[04:47:30] <gloops> done, with 45 minutes to spare haha https://ibb.co
[04:47:54] <XXCoder> hh your webpage scales it waaay up
[04:48:00] <XXCoder> looks great!
[04:49:42] <MarcelineVQ> It does, probably even better head on as well, it's hard to read the cleary at that angle

[04:52:06] <gloops> well i just took a couple of snaps in what look a good light, mrs wanted to show someone, shes taking it to a wedding in a bit lol
[04:53:07] <gloops> needed a bit of sanding worked where i touched second tool off slightly out but too late to mess about
[04:55:39] -!- veek has quit [Quit: Leaving]
[04:59:02] <XXCoder> you dont use paper to touch off?
[05:00:31] <gloops> on this occasion i simply felt for resistance while turning the tool, not much out but a few little deeper marks here and there, old oak doesnt sand quickly by hand, so it was just a quick rub over, should have been done 2 week ago but i didnt get round to it lol
[05:01:19] <gloops> nothing noticeable
[05:05:42] <XXCoder> cool

[05:59:31] <Blumax> Hello gloops
[05:59:39] <gloops> hello
[06:00:08] <Blumax> I'm looking for how to check the perpenducularity
[06:00:53] <Blumax> I use endstop effect hall, I can adjust the moment of detection accurately but before I must be sure that the machine is well perpendicular
[06:01:23] <XXCoder> theres few ways to do hat, Blumax
[06:01:32] <gloops> well, tramming is one way
[06:01:37] <XXCoder> do you have dial test indictor or bigger dial indictor
[06:03:37] <Blumax> XXCoder I do not understand

[06:05:20] <Blumax> Hello SVG URL spammeur :p
[06:05:21] <XXCoder> oops! sorry had to close client to stop the spam
[06:06:04] <XXCoder> http://www.kaefer-messuhren.de
[06:06:14] <XXCoder> thats test version
[06:06:31] <Blumax> Yes I have this :)
[06:06:44] <XXCoder> you could use it to check stuff
[06:06:56] <Blumax> But I'm not a reference surface
[06:07:11] <XXCoder> its for trimming your machine
[06:07:34] <XXCoder> basically you attach it to spindle somehow with offset as large as you can make it
[06:07:37] <gloops> https://www.youtube.com
[06:07:56] <gloops> also Blumax - surface the spoil board
[06:07:57] <XXCoder> then you rotate it around and adjust spindle till its nicely trimmed
[06:08:39] <XXCoder> interesting gloops lol
[06:09:23] <gloops> well, simple idea but will get you pretty close
[06:09:36] <XXCoder> yeah depends on your tols range
[06:09:49] <Blumax> Oh sorry, i want settle two motor Y granty
[06:09:51] <XXCoder> that wont work for .001" +- tol parts
[06:10:05] <gloops> ahh you mean square Blumax?
[06:10:29] <gloops> square the gantry, X > Y
[06:11:15] <Blumax> yes square :)
[06:11:32] <gloops> nobody really knows how to do that lol
[06:12:02] <XXCoder> measuring and adjusting is so much fun
[06:12:11] <XXCoder> measure corner to opposite corner
[06:12:18] <XXCoder> then other set
[06:12:21] <XXCoder> see if equal
[06:12:24] <Blumax> With a precision square and a feeler
[06:12:39] <Blumax> But the big square is very expensive :(
[06:12:40] <gloops> i started with a kitchen door - i knew had been machined reasonable square, then get x and y travel passing along each side just brushing it
[06:13:01] <gloops> you can do pythagoras 345 measurements etc
[06:13:18] <Blumax> I have a big glass table.
[06:13:28] <gloops> cut squares and try them with engineers square, draw lines on the board with a pencil and test that
[06:14:38] <gloops> it comes down to nudging the home switches a touch this way and that way until youre happy, i couldnt devise any scientific method to do it
[06:15:24] <Blumax> Ok, shame, I'll do as I can with the glass table ^^
[06:15:37] <XXCoder> well heres silly thing you can do
[06:15:43] <XXCoder> tape a paper to your table
[06:15:47] <XXCoder> attach a pen
[06:15:58] <XXCoder> program it to draw a recangle or square
[06:16:07] <XXCoder> it would show if your machine is out of square
[06:16:18] <XXCoder> circle is good though bit harder to check
[06:16:41] <XXCoder> in fact draw a diamond inside circle inside square
[06:17:02] <XXCoder> it combines all motion ponental issues so it could expose issues
[06:17:19] <XXCoder> square is single axis, diamond is equally two axis, circle hits ALL ratios
[06:20:33] <XXCoder> Hmm I'd suggest perment marker as it has softer tip so you dont break pen or pencil on paper lol
[06:20:54] <Blumax> The machine is 838 x 1425mm
[06:21:55] <gloops> yeah that circle in a square cut is a good guideline
[06:22:18] <XXCoder> diamond circle square yeah
[06:22:32] <MarcelineVQ> XXCoder: you'd want a mid-quality bic ball-point pen, low quality would clog up, other writing implements ends would wear during use
[06:22:50] <MarcelineVQ> Just to min-max this task :>
[06:22:59] <XXCoder> lol ok
[06:23:09] <MarcelineVQ> What we need is good card stock!
[06:25:57] <gloops> if you could set up 2 laser measures at one end of X, pointing diagonally across each other to the other end of X, you
[06:26:08] <gloops> could get a perfect square
[06:26:29] <XXCoder> hold on a second
[06:26:35] <gloops> but then you gotta get both angles perfect etc, its not worth it for a router
[06:26:41] <XXCoder> whoa picpaste is down?
[06:26:50] <gloops> imagbb
[06:27:27] <XXCoder> Blumax: https://imgur.com
[06:27:49] <XXCoder> I eyeballed the diamond a little but you get the idea lol
[06:28:00] <gloops> i had a vid of mine doing that test but must have deleted it
[06:28:09] <XXCoder> too bad
[06:28:39] <gloops> if the circle is a true circle, the square should fit nicely in it
[06:30:57] <Blumax> So if I understand correctly, I make a circle with the hand and I ask the CNC to do the square?
[06:31:08] <XXCoder> nah it does all the drawing
[06:31:27] <XXCoder> if machine has errors there is bunch different symtoms
[06:32:01] <XXCoder> squashed a little, skew, circle not properly placed inside square (or other way if gloops version)
[06:32:23] <XXCoder> circle is hardest because there is bunch of ponental issues
[06:33:08] <XXCoder> the transition where it goes to, stops and reverses on one axis while other is going max speed can cause issues if theres hardware issues
[06:33:22] <gloops> i could make you some code to run, but have to dash out right now for 10 minutes
[06:35:04] <Blumax> I know how to use the GCode and LinuxCNC, I have already machined quite a lot but I found problems of perpendicularity on certain piece. That's why I changed my machine.
[06:35:38] <XXCoder> heh I havent really worked on my machine for quite a while, but then I run big machines at work :P
[06:36:13] <XXCoder> biggest being a61 makino lol
[06:36:17] <XXCoder> whole cell
[06:40:05] <Blumax> Beautiful machine
[06:40:24] <XXCoder> it runs quite well, most times
[06:40:49] <XXCoder> couple flaws is chips tend to build up near tool break detect laser at far end
[06:40:53] <Blumax> Okay, I'll do with my glass table and a comparator. With pytagore I will check if the table is perpendicular.
[06:41:29] <XXCoder> today I ran tiny robodrill though lol
[06:41:39] <XXCoder> engraving very hard metal parts :P
[06:41:49] <XXCoder> its so hard tool gets useless after 30 parts
[06:42:15] <XXCoder> compare it to similiar engrave of stainless steel it can run 1,000 parts or more before tool gives up lol

[06:46:25] <diverdude> Hi, I am trying to run this code: https://www.brainy-bits.com to home my stepper motor...but when the code has been uploaded the motor is just giving a buzzing sound and is not moving. What am I doing wrong?
[06:46:58] <XXCoder> buzzing sound hm have you configured microstepping and such?
[06:49:51] <miss0r> XXCoder: This is how far I got with the control cabinet last night: https://imgur.com
[06:50:03] <diverdude> XXCoder: hmm yeah... i can move my motor if i just do something like this: https://paste.ubuntu.com so the motor is working
[06:50:17] <diverdude> XXCoder: its just the homing using accelstepper which is not working for some reason
[06:50:52] <XXCoder> I cnt directly answer that, its been a while but there may be troubleshooting stuff I can suggest
[06:51:03] <XXCoder> your machine may be trying to accerate too hard
[06:51:09] <XXCoder> given its configuration
[06:51:19] <miss0r> diverdude: Does the stepper give off sound?
[06:51:21] <XXCoder> miss0r: high quality cardboard!
[06:51:31] <diverdude> miss0r: yeah its like bzzzzzzzzzzzzz
[06:51:33] <miss0r> XXCoder: indeed hehe
[06:51:49] <XXCoder> no pizza leftover stains on it
[06:51:56] <miss0r> diverdude: Alright. That sounds like you are either a) accelerating too hard or b) running it intirely too fast
[06:52:09] <XXCoder> or microstepping is too high
[06:52:15] <XXCoder> it loses torque with that
[06:52:18] <diverdude> miss0r: aha so if i increase the delay it might help
[06:52:25] <miss0r> what delay?
[06:52:28] <miss0r> line no.
[06:52:55] <miss0r> the delay(1000) ?
[06:53:27] <diverdude> miss0r: here is a delay: https://www.brainy-bits.com delay(5);
[06:53:44] <miss0r> no
[06:54:03] <miss0r> that delay is during the setup phase. That does not effect your loop time.
[06:54:13] <miss0r> And using accelstepper you do not need to think about the loop time.
[06:54:36] <miss0r> you need to ajust: stepperX.setMaxSpeed(100.0); & stepperX.setAcceleration(100.0);
[06:54:44] <miss0r> although, those both seem alright
[06:54:55] <diverdude> miss0r: hmm ok. the thing is that i set stepperX.setMaxSpeed(100.0); stepperX.setAcceleration(100.0); so those values are definitely not to big
[06:54:56] <miss0r> (if those are, infact, the values you use
[06:55:15] <miss0r> so, what is it you have working, exactly?
[06:55:24] <diverdude> because in my working accelstepper code i set it to stepperY.setAcceleration(5000.0); stepperY.setMaxSpeed(10000.0);
[06:56:09] <miss0r> ahh...
[06:56:19] <diverdude> this very simple code is working;: https://paste.ubuntu.com
[06:56:37] <miss0r> hehe. in fact, this might be so slow that it does not seem to move / accelerate at all.
[06:56:45] <miss0r> Try to increase those values
[06:57:38] <miss0r> 2 secs, on the phone
[06:58:06] <gloops> give it some stick diverdude
[06:58:23] <diverdude> but if i set it to stepperX.setMaxSpeed(10000.0); stepperX.setAcceleration(5000.0); (in the homing code) no sound is even coming from the motors
[07:00:30] -!- syyl has quit [Ping timeout: 264 seconds]
[07:01:36] <gloops> im not familiar with stepperaccel whatever it is, but it sounds like the motors are being asked to perform extremes they cannot achieve
[07:03:12] <miss0r> back
[07:03:24] <XXCoder> wb
[07:03:40] <miss0r> diverdude: Theres something off about the code that is not working.-
[07:03:53] <miss0r> The way you are calling the accelstepper

[07:04:36] <XXCoder> yo jt
[07:04:56] <miss0r> diverdude: Please make me two pastebins; one of the code you want to have working, like you have tested it and failed. and one of the working code you have
[07:05:31] <jthornton> morning
[07:05:43] <miss0r> mornin' jt
[07:05:55] <jthornton> morning miss0r
[07:07:08] <MarcelineVQ> in case it's important to the task at hand: according to the docs setMaxSpeed is in steps/sec and setAcceleration is steps per sec per sec
[07:07:52] <MarcelineVQ> Which you guys probably guessed but I was curious about what units were being used so there it is just in case
[07:09:31] <miss0r> MarcelineVQ: No guessing :) We read manuals
[07:09:47] <miss0r> This is not ikea furniture. The manuals are worth something
[07:10:04] <XXCoder> yeah understanding machine is key
[07:10:36] <jthornton> thank you I spent a long time working on the manuals
[07:10:41] <XXCoder> hguy at work who badly hurt hand didn't understand that chip conveyer at back could run seperately and does, contrast it with most machines its linked
[07:10:42] <miss0r> pop, theres goes the warranty on my new computer PSY
[07:13:40] <jthornton> I need a 17" laptop that I can install linux for the road using a VM sucks
[07:14:07] <diverdude> miss0r: this is the code which i am trying to get to work (the homing procedure) https://paste.ubuntu.com AND here is the code which is working - which is just accelstepper moving forward and backward https://paste.ubuntu.com
[07:14:17] <Loetmichel> *hmpf... you think my wife will ever learn NOT to send the husband out for grocerys on an empty stomach? Wife has written up foods for 60 eur... i came back with foods and snacks for 217 eur... :-)
[07:14:54] <XXCoder> lol
[07:14:56] <jthornton> opps there goes the diet
[07:16:25] <diverdude> Loetmichel: haha nice :D and thats how we learn!!!
[07:17:22] -!- syyl has joined #linuxcnc
[07:18:29] <miss0r> diverdude: and you have sent the information it needs via the serial connection?
[07:18:34] <gloops> money spent on food is never wasted
[07:18:56] <diverdude> miss0r: mmm the setup procedure should just begin to home directly without getting input
[07:19:13] <diverdude> miss0r: its only in the loop procedure its asking for input
[07:19:18] <Loetmichel> gloops: not wasted unless it spoils before you can eat it
[07:19:36] <miss0r> diverdude: sure. But the 'setup' part does not actualy move the stepper
[07:19:44] <gloops> better get eating Loetmichel lol
[07:20:06] <miss0r> well, okay, it does
[07:20:16] <diverdude> miss0r: i think it does - its doing: initial_homing-=1000; // Decrease by 1 for next move if needed stepperX.run(); // Start moving the stepper
[07:20:38] <miss0r> Theres a bad error there, I would say
[07:20:48] <diverdude> miss0r: ok, which one is that
[07:20:51] <miss0r> The while loop, that does the homing oyu speak of there
[07:21:31] <miss0r> it calls stepperx.run(); each cycle, but in the end of that loop, theres a delay of 500ms, which means, the homing cannot move faster than two steps per second
[07:21:44] <miss0r> I would try to decrease that delay to perhaps 5-10ms

[07:23:33] <jthornton> ah yea that's what I meant I just woke up lol
[07:23:44] <miss0r> :]
[07:23:58] <Loetmichel> gloops: already at it... got my first coffee (latte macciato made by the wife) for today, sitting in front of 6 bread rolls layerst with cheese and cold meats... there is a reason i weight 19 and a half stone ;)
[07:24:11] <diverdude> miss0r: originally that was just delay(5); and it also did not work
[07:24:29] <Loetmichel> s/layerst with/covered in
[07:24:49] <MarcelineVQ> is a stone 20lbs?
[07:24:51] <miss0r> diverdude: Well, you can be very sure it does not work with 500 ;)
[07:25:05] <miss0r> well, it would move. but be ridiculously slow
[07:25:13] <miss0r> to the point you'd be unaware that it is even moving
[07:25:17] <diverdude> miss0r: yes that i also found out :)
[07:25:26] <Loetmichel> MarcelineVQ: i weight 124kg. a stone is 14lbs
[07:25:27] <MarcelineVQ> Er no that'd be too high wouldn't it, you work too hard for that number to work out
[07:26:07] <MarcelineVQ> gosh you weight more than I do, you must be tall
[07:26:49] <diverdude> miss0r: ok i tried completely removing the delay and then i can see that its actually moving
[07:26:59] <diverdude> miss0r: but its just moving very slowly
[07:27:56] <miss0r> is your homing switch activated at this point? (during your test now) ?
[07:29:06] <diverdude> miss0r: yes
[07:29:21] <miss0r> okay :) then move to the next loop - there you also have a delay, remove that as well
[07:29:41] <diverdude> miss0r: yeah already did that
[07:29:45] <diverdude> but still very slow
[07:30:05] <miss0r> Darn it. that would've made sense
[07:30:07] <Loetmichel> MarcelineVQ: 180cm
[07:30:36] <Loetmichel> <. fat old bastard ;)
[07:31:31] <miss0r> diverdude: comment out all serial communication
[07:31:45] <miss0r> and run it again (that could very well be slowing it down alot)
[07:31:46] <diverdude> miss0r: already done....does not help
[07:32:06] <miss0r> meh. Send me an updated version of your code, please
[07:33:02] <MarcelineVQ> Loetmichel: well, you're not short, that is a little higher weight-wide for that height though hehe
[07:33:10] <MarcelineVQ> *weight-wise
[07:34:04] <Loetmichel> MarcelineVQ: i SHOULD be around 90kg according to my doctor ;)
[07:34:39] <miss0r> ladies ladies... I'm ~120kg 187cm :)
[07:34:51] <MarcelineVQ> that sounds about right, though if you've got some muscle that could be low
[07:35:24] <miss0r> It mostly is, but I have around 5-6kg of stomach fat I would like to loose at some point
[07:35:26] <MarcelineVQ> Just get really buff, then if you're also fat you can blame the weight on your muscle density.
[07:35:46] <miss0r> but I just like burgers and soda too much, I guess :)
[07:36:17] * jthornton should be 12.5 stone but has been slacking and is 13 stone
[07:36:39] <MarcelineVQ> all y'all talkin' in stones and cm, what a crowd
[07:37:13] -!- Papagno has joined #linuxcnc
[07:37:26] <XXCoder> $wa 13 stone to pounds
[07:37:38] <XXCoder> %wa 13 stone to pounds
[07:37:42] <MarcelineVQ> "I only weight one stone, it's that one over there holding up the bridge."
[07:37:45] <diverdude> miss0r: the only thing which seems to make it run faster is to increase the stepsize....but that only makes it run so far...its still quite slow
[07:37:49] <andypugh> MarcelineVQ: Yes, very odd. cm are right out. I think in stones and mm
[07:37:53] <diverdude> miss0r: moment i will hsow you updated code
[07:39:04] <diverdude> miss0r: this is updated code: https://paste.ubuntu.com
[07:39:10] <miss0r> diverdude: So the speed does not change *at all* when you increase/decrease the MaxSpeed or MaxAcceleration?
[07:39:27] <diverdude> miss0r: motor is at least moving now but its still quite slow and i cannot see how to increase speed
[07:40:22] <miss0r> so editing the MaxSpeed or acceleration does not change anything?
[07:41:11] <diverdude> miss0r: well no and it makes sense why also since its moving many small steps so i guess it will accellerate and deaccell always
[07:41:42] <miss0r> Increase the length it has to move then
[07:42:04] <miss0r> If that does not change it either, I would have to say theres something slowing down your cycle time
[07:43:42] <diverdude> miss0r: no it does not help really
[07:43:49] <miss0r> hmm
[07:43:54] * miss0r is studying the text
[07:44:02] <diverdude> miss0r: maybe accelstepper is just bad for making homing procedure?
[07:44:05] <miss0r> how 'slow' it is, would you guess, in RPM?
[07:44:21] <miss0r> Could be. Write your own, if in doubt
[07:44:29] <diverdude> miss0r: oh thats a difficult question.
[07:44:44] <miss0r> ballpark answer
[07:46:06] <diverdude> i would say its moving maybe 1/3 cm per second
[07:46:16] <diverdude> in RPM i have no idea
[07:46:39] <diverdude> i dont even know how to see that
[07:47:41] -!- norias has joined #linuxcnc
[07:47:46] <miss0r> hmm
[07:47:52] <miss0r> hang on, reading like a mad man here
[07:48:16] <miss0r> It seems you still have the serial in working order?
[07:48:53] <miss0r> never mind. its not 'inside' the loop
[07:48:57] <miss0r> so it shouldn't matter
[07:51:15] -!- Sairon has quit [Ping timeout: 252 seconds]
[07:51:57] <miss0r> hmm
[07:52:10] <miss0r> Can you move the axis a good way away from the home switch and run it again?
[07:52:46] <diverdude> miss0r: yeah for sure
[07:53:05] -!- norias has quit [Quit: Leaving]
[07:55:17] <miss0r> Have you tried this with a good long run before? (After removing the delays in the loops)?
[07:55:27] <diverdude> yeah
[07:55:39] <diverdude> its moving at constant speed
[07:55:49] <miss0r> and it is creeping up on the homing switch very slowly?
[07:56:21] <diverdude> yes
[07:56:44] <miss0r> alright. and with the working example you had it running quite fast, with the same electrical setup?
[07:57:42] <miss0r> i.e. no change to microstepping on the driver?
[07:57:45] <diverdude> yeah much faster
[07:57:58] <diverdude> no change on driver
[08:00:27] <miss0r> https://pastebin.com
[08:00:40] <miss0r> try that, and let me know how it does
[08:04:31] <diverdude> miss0r: its moving a bit faster now...but its stopping before reaching the switch
[08:04:57] <miss0r> yeah. now it is only moving the amount of steps defined in the home_step
[08:05:14] <miss0r> faster, but not as fast as the working code?
[08:05:45] <diverdude> miss0r: i would say same speed as working code actually
[08:05:50] <miss0r> yeah
[08:06:10] <miss0r> Good. I think it was just using some stupid math in there, that made the loop take too long to cycle.
[08:06:37] <diverdude> miss0r: right...but i think its not homing now...its just moving to an absolute position
[08:06:48] <miss0r> I would make two constants: home_stepin and home_stepout
[08:07:21] <miss0r> One for each direction. And make sure the home_stepin(the one replacing home_step) is large enough to reach the home switch from anywhere on the travel
[08:07:43] <miss0r> thereby eliminating the math in the loop
[08:08:14] <miss0r> and the home_stepout should only be a distance large enough for it to release the homing switch
[08:08:16] <diverdude> miss0r: but is it possible to forexample ask accelstepper to run 10000000 pulses and then stop it when homeswitch is reached?
[08:08:37] <miss0r> diverdude: That is basically what you are doing right now
[08:08:39] <diverdude> miss0r: i thought that was the whole reason to move it small steps
[08:09:02] <diverdude> miss0r: yeah but right now its not even reaching the home switch. it stops before
[08:09:09] <miss0r> the loop that calls stepperX.run() exits when the homeswitch is acticated. afterwards you set the distance it needs to go to zero
[08:09:41] <miss0r> basically you just need to have a number large enough
[08:10:14] <diverdude> miss0r: ok you are actually right
[08:10:24] <miss0r> what a chocker :P
[08:10:27] <diverdude> miss0r: very interesting :D
[08:10:35] <diverdude> haha nono i did not mean it that way
[08:10:47] <miss0r> Yeah :)
[08:11:20] <miss0r> Would you mind humouring me with a picture of your setup?
[08:11:34] <diverdude> I just was surprised why this article then jumps so many hoops for a stupid slow scheme when i can just move the damn motor in a single move
[08:12:03] -!- Namidairo9 has joined #linuxcnc
[08:12:22] <miss0r> They are trying to make an example of using a constant speed method, which is flawed, in my opinion
[08:14:04] <Loetmichel> miss0r: i always use G64P0.05 on my programs. i can live with the 0.05mm deviation and it makes the run so much smoother, especially if you have a lot of corners/small arcs in the code
[08:14:17] <diverdude> miss0r: so now comes next question....how can i make the motor move faster....its now running at same speed as bespoke working code....but would be awesome if it was working faster
[08:14:19] -!- Namidairo9 has quit [Remote host closed the connection]
[08:15:13] <miss0r> Increase the maxSpeed
[08:16:28] <miss0r> just take note of one thing: when doing a movement like this.. or rather stopping it like you do - sending it no more pulses when the homing switch is reached, you do not have a ramp down. it stops abruptly. It might not be wise to move too fast
[08:16:31] <diverdude> miss0r: hmm no it does not really increase speed
[08:16:50] <miss0r> test with your other program, if you can increase the speed with that
[08:17:00] <miss0r> if you can, it still comes down to the cycle time of the arduino
[08:17:02] <diverdude> miss0r: yeah ok...but for homing i think its ok
[08:17:08] <miss0r> Indeed
[08:17:23] <diverdude> miss0r: yeah i am actually testing with other program already
[08:17:31] <diverdude> but it also does not really increase speed
[08:17:31] <miss0r> ha... :)
[08:17:57] <diverdude> what i remember though is that i once used grbl on this machine and it was able to move it faster than this
[08:19:14] <miss0r> https://www.airspayce.com
[08:19:42] <miss0r> perhaps one should start looking at maxSpeed as just that. A sort of failsafe :)
[08:19:54] <miss0r> 2 secs, I will have a quick glanse at the last stepper controller I programmed
[08:20:12] <diverdude> ahh yes ofc
[08:20:25] <diverdude> setspeed would be the one to use
[08:21:20] <miss0r> not sure about that, though
[08:21:21] <miss0r> :)
[08:21:48] <miss0r> I did not use it. I can upload you some code if you like to take a look at it? sadly all the comments are in danish, so I don't know what use you could have looking at it
[08:22:43] <diverdude> miss0r: well then its quite lucky that i am fluent in danish ;)
[08:22:55] <miss0r> That helps ;)
[08:23:20] <miss0r> https://pastebin.com
[08:23:37] <diverdude> anyway...setspeed did not seem to make much difference either hmmm
[08:23:55] <miss0r> yeah, I didn't think it would.
[08:24:05] <miss0r> How does that acceleration feel? does it do a nice ramp when starting?
[08:24:58] <diverdude> hmm
[08:25:12] <diverdude> actually not really
[08:25:59] <diverdude> why in denmark are you based?
[08:26:03] <diverdude> why=where
[08:26:19] <miss0r> A small city called Řlstykke. north of copenhagen(ish)
[08:26:32] <diverdude> oh cool. im in copenhagen hehe :D
[08:27:36] <miss0r> Sweet. I did not know there were any "locals" in here :)
[08:28:39] <miss0r> On another node: I'm not sure you can completely compare grbl and arduino when it comes to speed. I'm not sure how the internals of the grbl run when it comes to cycle time. it might be able to do it faster
[08:28:55] <miss0r> Try reducing the ramp time, and see if that makes any difference
[08:29:06] <diverdude> but grbl was running on this very arduino
[08:29:15] <diverdude> its just code which i downloaded to arduino
[08:29:57] <miss0r> oh, so a grbl shield?
[08:30:05] <miss0r> not the actual grbl software on the arduino
[08:30:37] <miss0r> well, there you have it: the grbl shield does not use microstepping, if I recall correctly.
[08:30:45] <miss0r> Are you doing so with your current controller?
[08:30:49] <miss0r> controller=driver
[08:31:15] <diverdude> hmm yes i actually am doing microstepping now
[08:31:23] <diverdude> is that the reason for the slow speed you think?
[08:31:50] <diverdude> moment i will show you
[08:32:18] <Blumax> XXCoder and gloops, i have solution.
[08:32:34] <gloops> elaborate Blumax
[08:32:46] <miss0r> The arduinos cycle time can only produce pulses at a given maximum speed. If your maxspeed is set to something higher/faster than the cycle time of the arduino it sorta' just caps off doing it as fast as it can.
[08:33:24] <miss0r> When you were using the grbl, one step pulse was translated into one full step on the stepper. i.e. what we shall call 'full speed'. Now that you are running microstepping
[08:34:00] <miss0r> one pulse translates to 1/16(? or what microstepping setup you have) which would make the maximum output of the arduino move 1/16 the speed as before
[08:34:22] <miss0r> so, yeah
[08:35:44] <miss0r> if I were you, i'd reduce the maxSpeed to a point where you can see it moves slower(the steps can be performed within the cycle time of the arduino)
[08:36:06] <miss0r> Not doing so could cause issues later on
[08:38:23] <miss0r> diverdude: If I have answered what questions you have for now, I'll move to the mill to do some brackets for my new controller.
[08:38:48] <miss0r> :) You are welcome to write me here, but don't expect a fast answer in the forseable future
[08:38:51] <diverdude> ah ok sorry...i was trying to capture and image of the driver settings for you. Its in an inaccessible place hehe
[08:38:55] <Blumax> XXCoder, gloops :
[08:38:55] <Blumax> https://prntscr.com
[08:39:37] <Blumax> If i draw triangle and that I measure it is 3 sides, we can calculate all other

[08:40:28] <Blumax> Precise measurements must be made, but it should work well.
[08:40:51] <diverdude> miss0r: its here anyway: https://imgur.com
[08:40:52] -!- pasky9 has joined #linuxcnc
[08:41:11] <Blumax> The end stops of my machine are positioned at the center of the guide rails. They are modeled on the drawing by the red dots.
[08:41:56] <diverdude> miss0r: cool!! what is that
[08:42:04] <miss0r> diverdude: Nice to see a fellow builder using wire ferrules (ledningstyller)
[08:42:34] <miss0r> diverdude: its the replacement controller for my maho 500c. Currently it is sporting a 1986 philips 432
[08:42:40] <diverdude> oh yeah...that makes it nice and tidy
[08:43:42] -!- pasky9 has quit [Remote host closed the connection]
[08:44:10] <gloops> yes geometry helps Blumax, however, we have to make exact physical measurements of these lines and angles, at this scale it is not easy with a laymans tools
[08:45:27] <diverdude> miss0r: so right now i have microstepping set to 12000. You are saying that to increase speed i should set it to maybe 200 instead?
[08:45:58] <Blumax> gloops, yes, with this method there is no need to measure angle, "just" length.
[08:46:39] <miss0r> diverdude: well 200 would land you the same place the grbl does
[08:47:08] <miss0r> But I assume you've choosen this to be able to microstep(make the motion less jerky). So perhaps you could settle for a slower speed, that is more smooth.
[08:47:18] <miss0r> That is something you have to try out to see what you're most happy about
[08:48:05] <Blumax> With a little rigor we should have a good result.
[08:48:12] <miss0r> bah.. Time got away from me. I'll smoke a cigarette, then I have to get back into the house'n make pancakes for the kid & wife

[08:50:38] <diverdude> miss0r: its kind of a hobby thing hehe. But I am building a machine for controlling a microscope

[13:03:02] <diverdude> I have a 3-phase stepper motor which runs at 300 steps per revolution and a driver which pulses 200 steps per revolution. I made arduino program like this: https://paste.ubuntu.com which runs the motor 300 steps at 300 steps/sec at very high accelleration. In my understanding this should make the motor drive 1 second in 1 direction and then 1 second in the opposite direction. For some reason it runs 2 seconds in each

[13:08:33] <diverdude> miss0r: ohh i see
[13:08:44] <diverdude> maybe i confused some things
[13:08:46] <miss0r> diverdude: What exactly do you see? :)
[13:09:07] <miss0r> Are you quite positive your stepper does not have 200 steps/rev? i.e. the driver is doing a 1:1
[13:09:10] <diverdude> i see the machine is taking 2 seconds to move in each direction
[13:09:33] <diverdude> miss0r: well my driver has 200 steps/rev and my motor has 300 steps/rev
[13:09:44] <diverdude> miss0r: which makes it diffucult for me to understand
[13:09:46] <miss0r> is it a geared stepper?
[13:09:58] <diverdude> yes i believe so
[13:10:14] <miss0r> do you have a part number?
[13:10:50] <diverdude> i do
[13:10:53] <miss0r> you see, with steppers the most common ones are 200steps/rev. There are some 400steps/rev. but with these smaller ones 200 is the standard ish
[13:10:56] <miss0r> let me see :)
[13:11:11] <diverdude> this is my driver: https://www.lightobject.com and this is my motor: https://www.lightobject.com
[13:11:40] <diverdude> miss0r: yeah i can adjust this driver to different settings...now its at 200 steps/rev
[13:12:29] <miss0r> Indeed. You've found one of the odd ones :D
[13:13:01] <diverdude> yeah... unfortunately....if you know of a better motor/driver combination than this i am all ears
[13:13:02] <diverdude> :)
[13:13:51] <miss0r> I know of others, I'm not sure about better :)
[13:13:56] <diverdude> miss0r: ack...i have to go for 30-60 minutes....will you be here in about 1 hour?
[13:14:24] <miss0r> Sure.. I'm about to fire up the cnc and make the parts I didn't manage to get done earlier. Just write me, and I will answer as soon as I see it
[13:14:41] <diverdude> ahh awesome :) thnx man
[13:15:56] <Rab> miss0r, did you mill or punch the dsub cutouts in that enclosure you posted yesterday?
[13:16:05] <miss0r> rab: I milled those
[13:16:34] <miss0r> unfortunatly I don't own a punch'n die set for d-subs
[13:16:54] <miss0r> and I didn't feel like making three different ones for this small project ;)
[13:17:03] <Rab> It's a big financial outlay.
[13:17:21] <Rab> What was your source for the dsub dimensions?
[13:17:52] <miss0r> rab: This quite excellent one_ https://www.norcomp.net
[13:18:15] <Rab> miss0r, sweet, thanks! I think that's what I've used in the past.
[13:18:40] <miss0r> and you lost it? :)
[13:19:18] <Rab> Just wondering if there's a canonical source. I usually hit up datasheets from a big player like Norcomp or Amphenol.
[13:20:15] <miss0r> hehe. That there was basically one of the first three hits on google image search, when searching for "d-sub cutout template"
[13:25:32] <miss0r> rab: About the financial aspect of it; This is a project I'm making for myself.. so time is not realy a factor in this. I just couldn't be bothered :)
[13:26:24] <miss0r> rab: also, should you be curious; this is what it looks like bend into shape & mounted in the control panel: https://imgur.com
[13:28:27] <Rab> miss0r, looks great! Nice latching dsubs.
[13:28:44] <miss0r> rab: not so nice, actualy. I'm having issues with it
[13:28:45] <Jin^eLD> miss0r: what thickness did you chose?
[13:28:58] <miss0r> Jin^eLD: its 1mm plate
[13:29:35] <miss0r> rab: the latches I bought are designed to be mounted directly on the d-sub, so it does not pull the connector close enough. I'm searching for a solution
[13:30:34] <Loetmichel> Rab: we always do them symetrically
[13:30:58] <Loetmichel> sou you can fit the dSub in both orientations
[13:31:12] <miss0r> and the only reason I'm *stuck* with the latches, is because the controller I'm replacing is using them.
[13:31:14] <Loetmichel> http://www.cyrom.org
[13:31:18] <Loetmichel> like that
[13:31:27] <miss0r> Loetmichel: Do you have any experience with the latch locks?
[13:31:43] <Loetmichel> miss0r: like on the old thicknet connectors?
[13:31:46] <Loetmichel> nope
[13:31:55] <Loetmichel> i dont use them because they dont work well
[13:32:18] <miss0r> Me neither, I like the screw better. But as I am doing a plug'n play replacement of what is on my mill currently, I sorta' need to use them
[13:32:34] <Loetmichel> cant you remove them from the controller?
[13:32:44] <Loetmichel> and replace them with screws/bolts?
[13:33:08] <miss0r> sadly, no. They are factory made in one piece with the d-sub
[13:33:28] <miss0r> like riveted
[13:33:29] -!- ekr has quit [Ping timeout: 250 seconds]
[13:33:36] * miss0r did think of that
[13:33:40] <Loetmichel> rivets can be drilled open...
[13:33:49] <Loetmichel> but i see your predicament
[13:34:11] <miss0r> sure, but then I would have no way of attaching anything new. The idea is, that I can reinstall the old controller within a few hours, should the new one fail
[13:34:21] <Loetmichel> i am sorry to say: you are fubared...
[13:34:33] <miss0r> The problem is, I'm using this machine in my daily production, so I can't realy be too intrusive to it
[13:34:42] <miss0r> I had that feeling :]
[13:34:49] <Loetmichel> those clips didnt work well in the 70s and 80s... they dont work any better now ;)
[13:35:38] <miss0r> I mean, other than making a craptacular solution, where I add a male->female block bolted to the d-subs in my plate, and have the latchs on the back side of those. But that just seems exsessive
[13:36:12] <miss0r> bulky.. and another point of faliure ext
[13:36:15] <miss0r> ect*
[13:36:56] <Rab> Panel thickness can mess up any retention mechanism if the connectors are rear-mounted. I have that problem with threaded jack nuts. Are the cutouts big enough to front-mount the connectors?
[13:37:49] <miss0r> rab: sadly no. And even if they were, I would have issues with the two 50 pole d-subs, as they are with a screw terminal breakout board on the back, that I would not be able to get through the hole
[13:38:11] <Rab> oof
[13:38:40] <miss0r> I just want a solution that does not look like crap & is relieable
[13:38:49] <miss0r> Short of double sided tape, I'm out'a ideas :]
[13:40:22] <miss0r> gawd, it will be sweet with the new controller.. I'm transfering a 52kb g-code to the mill at the moment. I'm nearing completion, and I have been "uploading" for 16minuts
[13:40:37] <Loetmichel> miss0r: hrhr
[13:40:50] <Loetmichel> i once did a 35MB gcode
[13:41:03] <miss0r> Thats what you get for emulating a punch tape terminal, through a 2400baud serial connection
[13:41:11] <miss0r> Nice :D
[13:41:19] <miss0r> I only have 64k of memory on this one, anyway :D
[13:41:48] <Loetmichel> https://www.youtube.com <- took quite a while... about 30 hours IIRC. (caution loud)
[13:42:34] <miss0r> Yeah, those 3D parts are a bitch :D That is something I will be able to do once the new controller is in place.
[13:42:43] <miss0r> You can imagine, that is very limited with 64k memory

[13:53:51] <fragalot> it came with a LOT of arbors
[13:54:01] <miss0r> you didn't happen to find a tapping head in there as well? :)
[13:54:08] <miss0r> how many are we talking?
[13:54:09] <fragalot> you say that

[13:54:27] <gloops> throughout the day
[13:54:31] <fragalot> we're talking an entire drawer (400mm wide) full

[13:55:56] <fragalot> miss0r: didn't take pics - forgot to take my phone with me and cba to go back now :P
[13:56:00] <fragalot> will do tomorrow
[13:56:11] <fragalot> tried the high speed head too

[13:59:37] <miss0r> that is pretty sweet. What speed was it able to do?
[14:00:15] <fragalot> miss0r: don't have a tachometer
[14:00:49] <miss0r> fragalot: In about 30 mins I think, a guy called diverdude(apparently a fellow dain) will be back here asking questions about grbl shield on arduino. He is having some issues. I think your insight will do him good
[14:01:16] <fragalot> you mean my superior documentation reading skills?
[14:01:43] <miss0r> I helped him earlier to the best of my knowledge, but theres just something off about driving a three phase 300steps/rev with a driver that says 200 steps/rev in the lowest microstepping setting... Something does not add up
[14:01:49] <miss0r> Sure.. call it that ;)
[14:02:36] <miss0r> (19:10:42)<diverdude>this is my driver: https://www.lightobject.com and this is my motor: https://www.lightobject.com
[14:03:11] -!- P1ersson has joined #linuxcnc
[14:04:00] <fragalot> there's always going to be something off with that motor and driver combination
[14:04:12] <fragalot> thankfully the driver itself doesn't give a damn what the motor will actually do
[14:04:20] <miss0r> Indeed.
[14:04:23] <fragalot> it probably assumes 1:1 step is 200 steps/rev
[14:04:31] <miss0r> yeah. What I was thinking exactly
[14:04:33] <fragalot> and 400 steps/rev is 1:2
[14:04:46] <miss0r> He just can't use the readout for other than assuming 200 is 1:1, and so forth
[14:04:57] <fragalot> yea
[14:05:01] <fragalot> easy. :)
[14:05:04] <miss0r> yep
[14:05:15] <miss0r> Always nice to have a second opinion.
[14:05:34] <miss0r> So, wensday, I will call GLS and claim insurance
[14:05:43] <fragalot> alright
[14:06:01] <miss0r> I'm pretty sure you can start looking for another tapping head.. Sorry man
[14:06:15] <fragalot> at least I have the collets & nut
[14:06:24] <miss0r> Always good to have :]
[14:06:28] <fragalot> I'll just make my own tapping head, with blackjack;. and hookers.
[14:06:48] <miss0r> Indeed :D
[14:07:08] <miss0r> you know, my closest friends and I use that same refrence pretty damn often.. we are sad people
[14:07:29] <fragalot> does your wife know?
[14:07:32] <miss0r> But I'm sure they will be more than ready to pay up, as I have been calling them daily since I started :D
[14:07:45] <miss0r> sure.. she "looks to the sky" every time
[14:07:50] <fragalot> different department
[14:08:01] <fragalot> you've been calling customer service

[14:08:13] <fragalot> without them actually having to do so
[14:08:35] <miss0r> sure. Insurance is another matter entirely. I know. Lets just hope for the best

[14:58:51] <Jin^eLD> hmm, so, my buddy is now trying to compile the comp on his linuxcnc installation, so RT mode as a kernel module; I as developing it in userspace mode
[14:59:01] <Jin^eLD> and for him it all fails because of a different compiler
[14:59:12] <Jin^eLD> I was assuming that halcompile would enfornce the same flags everywhere?
[14:59:14] <Jin^eLD> is that not the case?
[14:59:15] -!- candyonetoo has quit [Ping timeout: 252 seconds]
[15:01:28] <Jin^eLD> ok turns out he is on 2.7.11, not sure if that could have such an influence
[15:01:53] <fragalot> it might, depends on why it fails
[15:02:05] <Jin^eLD> from what I see it tries to use ISO C90 mode
[15:02:18] <Jin^eLD> while I was surely using C99 stuff during development, because it "just worked" here
[15:08:16] <Jin^eLD> does linuxcnc support "distro updates" via apt-get? so that he would not lose his setup/settings but just update linuxcnc?
[15:10:00] <Roguish> Jin^eLD: no distro updates. remember it's based on realtime kernel.
[15:10:19] <Jin^eLD> I thought linuxcnc rolls its own debian based distro?
[15:11:26] <Jin^eLD> so what would you suggest, whats the easiest way to get 2.7.14 without losing configuration? I think he starte with a 2.7.11 live cd and installed to disk from it (that was a while ago)
[15:11:27] <Roguish> yes it does that. sorry, probably misread your question.
[15:12:41] <Roguish> I run a master version, and when it gets a new build, it will update. without blowing the config.
[15:13:32] <Roguish> it's when, say you want to go from debain 8 to debian 9 that things don't work.
[15:14:55] <Jin^eLD> ok, thats what I meant... and is linuxcnc 2.7.11 to 2.7.14 like going from a distro to distro, or would a "regular" update do it? I am really not that familiar with the linuxcnc distro itself
[15:15:56] <Roguish> regular update should work fine, given the proper repositories are spec'd.
[15:17:00] <Jin^eLD> and any ideas about the kernel flags? should I rewrite the comp in C90?
[15:17:11] <Jin^eLD> or will 2.7.14 use C99?
[15:17:22] <Roguish> sorry, way above my pay grade.
[15:17:44] <Jin^eLD> I should probably ask in -devel
[15:17:49] <Jin^eLD> thank you for the update hints
[15:17:50] <Roguish> yes
[15:17:59] <Roguish> no problem.
[15:18:00] <Jin^eLD> I'll tell him to try a normal update first and lets see how far we get
[15:18:30] <Roguish> sounds like a good call.
[15:20:21] -!- Ross has quit [Ping timeout: 252 seconds]
[15:27:01] <Jin^eLD> did not work, he ran apt-get update, but he's still on 2.7.11
[15:28:07] <CaptHindsight> Jin^eLD: what kernel flags are being used?
[15:28:40] <CaptHindsight> my question has little to do with the upgrade not upgrading
[15:29:41] <Jin^eLD> CaptHindsight: I do not see the exact flags in his paste, but I see messages like:
[15:29:48] <Jin^eLD> warning: ISO C90 forbids mixed declarations and code
[15:29:59] <Jin^eLD> or
[15:30:00] <Jin^eLD> error: Á
[15:30:02] <Jin^eLD> crap
[15:30:08] <Jin^eLD> loop initial declarations are only allowed in C99 mode
[15:30:17] <Jin^eLD> stuff like that, so it seems to use C90 mode
[15:30:58] <andypugh> Jin^eLD: Might be easiest to update via Synaptic
[15:31:22] <Jin^eLD> i am currently looking at http://linuxcnc.org chapter 4.1
[15:31:23] <andypugh> If the repository is set up right (and an ISO install will be) then it’s automatic.
[15:31:45] <CaptHindsight> what is being compiled? maybe I need to read more of the backlog
[15:31:58] <Jin^eLD> I am not a debian/ubuntu guy, do you have a link for me or do I just google for synaptic update?
[15:32:29] <Jin^eLD> CaptHindsight: a C .comp via halcompile, it worked fine in userspace mode where I was developing it using halcompile from 2.7.14
[15:33:06] <Jin^eLD> but now my buddy is trying to build it on the actual PC that is connected to his mill, and turned out he has an older linuxcnc version there and the comp won't compile due to the above compiler errors
[15:33:29] <diverdude> miss0r: hi, are you still here?
[15:34:03] <andypugh> Can you halcompile a very simple (and pre-existing) comp?
[15:34:23] <CaptHindsight> Jin^eLD: if apt-get update didn't work then he needs to setup his repos
[15:34:31] -!- SpeedyG15 has joined #linuxcnc
[15:34:37] <andypugh> halcompile should just compile for the system it is running on.
[15:35:14] <andypugh> 2.7.11 to 2.7.14 should have no effect at all on halcompile. It’s a set of minor bugfixes
[15:35:14] -!- SpeedyG15 has quit [Remote host closed the connection]
[15:35:18] <Jin^eLD> andypugh: his halcompile works as such, and the compiler errors indicate that I was simply using too advanced C :) so I think it works "for his system", which we now found out is Debian Wheezy
[15:36:02] <andypugh> You have to be careful what you use in ,comp files. You should only really use basic C, no libraries.
[15:36:27] <Jin^eLD> andypugh: I am not using any libraries or whatever, its really stupid stuff like variable declarations in for loops and thingsd like that, C90 vs C99
[15:36:41] <andypugh> (and you can automatically use the rtapi_ math (etc) libraries.
[15:36:56] -!- ziper1 has joined #linuxcnc
[15:37:44] <Jin^eLD> andypugh: I would expect that halcompile uses the same restrictions in userspace mode, i.e. if it can only do C90 for the kernel, then I'd expect it to use C90 in userspace as well
[15:37:46] <Jin^eLD> is that not the case?
[15:37:59] <Jin^eLD> or is it a 2.7.11 vs 2.7.14 thing? thats what I am trying to find out...
[15:38:09] <Jin^eLD> if its the same on 2.7.14 then I should rewrite my comp
[15:38:16] <Jin^eLD> userpace did not give me any warnings whatsoever
[15:38:40] -!- ziper has quit [Ping timeout: 250 seconds]
[15:40:13] <Jin^eLD> would anyone who has 2.7.14 in rt mode be willing to quickly try and compile my comp and tell me if it works? that'd be a great help in determining how to approach the issue
[15:40:28] <andypugh> Nothing sugnificant as far as infrastructure changed between 2.7.11 and 2.7.14
[15:41:12] <Jin^eLD> so both would still be on wheezy?
[15:41:36] <andypugh> Both can be on a large range of OS-es.
[15:41:54] <andypugh> There is no link between any version of LinuxCNC and a specific OS.
[15:42:15] <andypugh> (years ago someone even managed to run it on MacOS)
[15:42:18] <Jin^eLD> well, he started with a linuxcnc live cd download, dunno how its being packaged
[15:42:43] <Jin^eLD> I thought that linuxcnc kind of maintains a distro spin based on debian/ubuntu
[15:42:52] <Jin^eLD> but I may be worng here
[15:43:05] <andypugh> The liveCD installs a Linux version, but the package can run on others. (and that version can be updated without changing the OS)
[15:43:27] <Jin^eLD> that I understood, the most trickery why the live cd is helpful is all the RT stuff
[15:43:54] <andypugh> Yes, you get Linux + RT kernel + LinuxCNC all working for little effort.
[15:44:10] <Jin^eLD> and of course I wrote the comp on my regular notebook, just compiled myself 2.7.14 linuxcnc from git and ran it in userspace mode
[15:44:25] <andypugh> But you can choose Linux distribution pretty freely as long as you can make on of the RT kernels work on it.
[15:44:43] <andypugh> (that’s RTAI, PREEMP-RT or Xenomai)
[15:44:48] <Jin^eLD> that'd be too advanced for him - not an IT vampire :)
[15:45:12] <andypugh> Where is your comp?

[15:46:45] <diverdude> I have a 3-phase stepper motor which runs at 300 steps per revolution and a driver which pulses 200 steps per revolution. I made arduino program like this: https://paste.ubuntu.com which runs the motor 300 steps at 300 steps/sec at very high accelleration. In my understanding this should make the motor drive 1 second in 1 direction and then 1 second in the opposite direction. For some reason it runs 2 seconds in each
[15:47:08] <Jin^eLD> if you have the environment set up and halcompile is available, then just "make gearbox" will do it
[15:48:06] <fragalot> diverdude: the driver likely assumes you have a 200 step motor, and will act as 1:1 step for your 300 step motor (eg, 300 pulses will be 1 revolution)
[15:48:51] <fragalot> diverdude: as for your understanding of the time: not really. it's not a linear acceleration
[15:49:40] <diverdude> fragalot: ok i see. What is then a good way to figure out what the maximum speed of my system is?
[15:50:08] <fragalot> you keep increasing the speed (with a load on it) until it stops being reliable
[15:50:15] <fragalot> then back down a bit
[15:50:26] -!- candyonetoo has joined #linuxcnc
[15:50:52] <fragalot> there are calculators out there that should get you close but I can't remember the link
[15:53:10] <andypugh> Jin^eLD: That’s a heck of comp. I haven’t seen one with separate headers before.
[15:53:35] <diverdude> fragalot: with a load on it?
[15:54:44] <Jin^eLD> andypugh: that's "fake" because I #include the sources too in the end, but I still wanted to have it separate for a better overview, didnt want to dump everything in one file (I let the preprocessor do that)
[15:56:38] <andypugh> Anyway, it isn’t wanting to compile on my RTAI LinuxCNC 2.8.0 system.
[15:57:02] <Jin^eLD> andypugh: same kind of C90 / C99 errors?
[15:57:56] <andypugh> https://pastebin.ubuntu.com
[15:59:23] <Jin^eLD> k, C90 as well, thank you!
[16:00:46] <Jin^eLD> btw he managed to update using synaptic, but says the splash screen still shows 2.7.11
[16:09:37] -!- Guest32896 has joined #linuxcnc
[16:16:19] <diverdude> fragalot: so if i set my driver to 200 it will really be 300, if i set it to 400 it will raelly be 600, if i set it to 10000 its really 15000...the driver does that mapping automatically. correct?

[16:19:57] <Jin^eLD> ok, hacked up the linuxcnc makefiles to enforce -std=c90, I think I should be able to fix my comp in a userspace env without a "real" system
[16:20:06] <Jin^eLD> andypugh: thanks once more
[16:24:33] <andypugh> Jin^eLD: The splash screen should show 2.7.14 if he really did update.
[16:24:50] <andypugh> What does Synaptic itself think the version is?
[16:24:51] <XXCoder> yo andy
[16:24:55] <andypugh> Hai
[16:25:04] <XXCoder> how goes yiur spindlke project
[16:25:14] <andypugh> Which one?
[16:25:22] <XXCoder> one you had video of
[16:25:39] <andypugh> Finished
[16:25:44] <XXCoder> cool :)
[16:26:06] <andypugh> Have you seen the video? (do autocaptions work at all)
[16:26:10] <Jin^eLD> andypugh: he reran it and rebooted again and seems now it worked, with 2.7.14 in the splash, so seems
[16:26:12] <Jin^eLD> OK
[16:26:36] <XXCoder> autocraptons does work but cuts out sometimes and once a while weird results when high inference
[16:26:54] <XXCoder> otherwise no issues I can see. you speak clearly apparently
[16:37:06] <andypugh> It’s doing very well.
[16:37:22] <andypugh> When I did my first video in 2010 it was utterly, laughably, hopeless.
[16:37:46] <andypugh> I don’t think that they had used any Yorkshire acents to train it with.
[16:38:02] <XXCoder> nice
[16:38:27] <andypugh> It made absolutely no sense at all. I think “ER32 collet” came out as “wrinkled popes” for example.
[16:38:48] <XXCoder> heh thats why I call it autocraptons
[16:38:56] <XXCoder> its definitely a lot better, but not always
[16:39:21] <XXCoder> its still iffy on specialized words but good

[16:58:00] <XXCoder> that looks good. :)
[16:58:04] <miss0r> It seems I have the most of the day tomorrow only for completing this. I think by evening tomorrow, I will be programming this thing. or atleast realy close
[16:58:08] <XXCoder> I really need to work on mine
[16:58:34] <miss0r> wait. don't tell me its nice yet. Just wait till I start pitchforking wires in there :D

[17:00:33] <miss0r> You need to be extra carefull to get all the chips out of the cabinet, now that theres a motherboard in there as well
[17:00:53] <XXCoder> getting those very puffy filters for air vents?
[17:01:08] <XXCoder> dunno what its called, we use lot of em at all machines at work
[17:01:41] <miss0r> Theres those filters in both the intake and the output vents on this one
[17:01:54] <XXCoder> nice
[17:02:00] <XXCoder> I have no idea where to buy em
[17:02:01] <miss0r> I don't know that they have a specific name. I just buy some complete units from schneider electric.
[17:02:16] <miss0r> I can get you the EAN number, if you are interrested?
[17:02:44] <XXCoder> while I dont think I will need for while sure I can find a link with number so I can look up later
[17:03:02] <miss0r> 7512404045
[17:03:20] <miss0r> just google that, you'll find a seller near you
[17:03:47] <XXCoder> interesting thats little different
[17:04:18] <miss0r> I used to use them all of the time on electrical cabinets when I build those
[17:04:19] <XXCoder> one at ork comes in large roll sheet maintance guy cuts em into rectangles
[17:05:08] <miss0r> sure. I just buy the ready made ones that fit in these. its probally 100x as expensive.. but at a few $ a piece, who cares when you only need two :D
[17:06:12] <miss0r> I'll call it a night. See you around
[17:06:16] * miss0r is out
[17:06:17] <XXCoder> night

[18:16:39] <andypugh> I would asssume that you can build what you want from modular industrial switches?
[18:17:32] <andypugh> eBay to the rescue. 20A 660V https://www.ebay.com
[18:20:43] <_unreal_> to large :/
[18:20:50] <_unreal_> wont fit
[18:24:22] <andypugh> Relay then :-)
[18:28:31] <andypugh> diverdude: Steppers are all OK with 100V or so. It’s what the drivers can handle that matters. (and you want to run as high a voltage as you can while still having a little margin)
[18:31:18] <andypugh> So I was given a brand-new Moog G400 servo yeterday. 29Nm 3kW. What should I use it for :-)
