[00:00:08] <Tom_L> but with the 6i25 instead of the 5i25
[00:00:47] <Getty> i must say i am abit confused, but probably cause there is much not written in the description of those cards hehe :D
[00:01:06] <Getty> i mean the picture of the both things you showed me are already equally, what is the crucial difference point here?
[00:01:07] <Tom_L> download the user manual and read it for each one
[00:01:09] <Getty> want to understand
[00:01:11] <XXCoder> you might be able to look up model #s on those
[00:01:24] <XXCoder> see if its model # for stepper or servo
[00:01:41] <Tom_L> i forget which is which but one is for stepper and one is for servo
[00:02:05] <Getty> ok.... so that is kinda a crucial attribute, and one for stepper cant be used for servo and one for servo cant be used for stepper?
[00:02:06] <Tom_L> one will talk about stepgen and one will talk about pwmgen
[00:02:20] <Tom_L> bingo
[00:02:20] <Getty> hey, if its about PWM, i can do that! :D
[00:02:24] <Getty> on my own! :D
[00:02:45] <Tom_L> likely not as efficient as the mesa card
[00:03:01] <Getty> sure :D... ok i think i remember what is the topic here
[00:03:08] <Getty> there is the same topic on the LED world
[00:03:11] <Getty> there are PWM controlled LED
[00:03:29] <Getty> and there are some which are somehow like PWM, but you cant use the same chip, i dont know what its called, but that was a topic on development
[00:03:32] <Getty> rarely used stuff
[00:03:44] <Getty> but i assume that is the same difference, PWM is just one way to control, and.. there is that other, ok
[00:03:56] <Getty> my dad said, we cant make the device capable of doing both methods
[00:04:11] <Tom_L> listen to him
[00:04:16] <Getty> haha, he is dead ;)
[00:04:51] -!- justanotheruser has quit [Ping timeout: 252 seconds]
[00:04:57] <Tom_L> that's why it's important you know what you've got
[00:04:59] <Getty> he left me the worst laboratory someone can imagine, but a lot of stuff i could extract that were useful, i threw away soooooooooooooo much electronics
[00:05:07] <Getty> well i will find out
[00:05:13] <Getty> is there are more then steppers or servo?
[00:05:23] <Tom_L> not really
[00:05:33] <Tom_L> not practically anyway
[00:05:58] <Tom_L> there are different ways to drive servos though
[00:06:07] <Getty> so if i would get that MESA card with the 2 ports for extension cards, and would buy one for stepper and one for servos, i would be probably able to cover everything?
[00:06:22] <Getty> "everything"
[00:06:36] <Tom_L> you can swap the daughter cards, yes
[00:06:50] <Tom_L> you would need to reload the firmware to reflect the change though
[00:06:54] <Tom_L> it's not hard to do
[00:07:11] <Getty> wait, i cant run both at once? I mean the MESA thing looks like to allow 2 extension cards, thats why i ask
[00:07:30] <Tom_L> i'm not sure, i don't have those cards
[00:07:40] <Getty> ok, something to find out
[00:08:09] <Getty> are there probably people with stepper+servo setups who know? or would that be ultra rare case?
[00:08:38] <Tom_L> if you check back in ~8 hrs someone will be awake that can answer that
[00:08:50] <Getty> yeah i anyway need to do something totally else
[00:09:02] <Getty> i am superstressed with 1000 things but somehow felt the need to join here and ask that topic to get a drill
[00:09:10] <Getty> i mean a drill of the direction ;)
[00:09:38] <Getty> I was already surprised to realize that a Raspberry is not doing the show (so good) :D but thats ok, doing it real is fun
[00:10:31] <Getty> https://i.imgur.com here btw the testing station i made for my boards mass tests, we try to find bugs and i always just had one device to test, so now i run a battery :D
[00:10:47] <Tom_L> i think the graphics is what kills the Rpi
[00:10:55] <Getty> https://i.imgur.com from the back
[00:11:21] <Getty> Tom_L: the bigger problem seems to be that nothing of the specialized drivers is available, so most stuff common to LinuxCNC doesn't work there
[00:11:52] <Getty> although it seems there is some compatibility check on release of LinuxCNC, so raspberry pi will work at least on what is "core"
[00:12:32] <Getty> the T30 plan i have actually seems to have a big disadvantage, it cant get powered off! :D hehe....
[00:12:45] <Getty> i probably do not want a LinuxCNC 24/7 on, right? :D
[00:13:07] <XXCoder> depends on usercase. at work we leave most machines 24/7
[00:13:13] <Tom_L> there are probably some that are
[00:13:17] <Getty> i mean not that i doubt that it cant do it, more like that i shouldn't risk that it fires up something while i am not there

[01:15:59] <XXCoder> busy guy
[01:16:03] <Getty> ah ok
[01:16:14] <Getty> i was just kinda curious, cause he suggested me first that Ethernet Solution
[01:16:24] <Getty> isn't that like the master of latency?!
[01:16:41] <XXCoder> it uses that different from what I understand
[01:16:51] <XXCoder> thats why you dont use it with regular ethernet card
[01:17:14] <Getty> oh i see

[02:30:20] <ChunkyPuffs> this is getting dire
[02:30:47] <ChunkyPuffs> I can cut shit just fine, but I can't get the cut to go to the depths I want it to go to
[02:30:53] <ChunkyPuffs> this is a misunderstanding of fusion or something

[03:56:42] <crazyben> Good moning
[03:57:01] <crazyben> Good morning
[03:57:21] <XXCoder> good monetizing for you also
[04:03:57] <crazyben> Anyone here using ethercat on a 64-bit environment?
[04:05:19] <XXCoder> in what way? as network or as commucation cable between controller and machine?
[04:06:04] <crazyben> xxcoder: yes
[04:06:17] <XXCoder> on both? both isnt same thing.
[04:06:58] <crazyben> xxcoder: As a communication cable to control the machine.
[04:08:01] <XXCoder> there is MESA card that uses ethernet yeah
[04:08:09] <XXCoder> bits dont really matter in this respect.
[04:12:22] <crazyben> do you use this in your setup - if yes, on which os?
[04:19:08] <crazyben> can see my components now..

[06:07:09] <jthornton> morning
[06:07:54] <XXCoder> hey jt
[06:13:18] <XXCoder> how did making minium example go
[06:13:42] <jthornton> never did get it to work
[06:14:09] <XXCoder> yeah? one I modified from yours worked fine
[06:14:33] <XXCoder> or did you mean it didnt work with linucnc?
[06:14:43] <XXCoder> becaue I didnt test that
[06:15:15] <XXCoder> im pretty sure linuxcnc would require haltranslations defined
[06:15:18] <jthornton> I didn't try it on it's own just with linuxcnc
[06:15:46] <XXCoder> maybe just add a sphere at 0,0,0 and add haltranslation of all 3 axis on it
[06:16:00] <XXCoder> then move sphere upwards 400
[06:16:11] <XXCoder> then see if it works

[06:32:59] -!- gloops has joined #linuxcnc
[06:33:54] <jthornton> what did you modify to make it run stand alone?
[06:35:09] <XXCoder> all machines can be stand alone
[06:35:22] <XXCoder> just do this: phyton ./somefile assuming you in same dir
[06:35:52] <XXCoder> you wont be able to do anything besides change viewpoint zoom in out
[06:35:57] <XXCoder> but thats good for fast testing
[06:36:01] <jthornton> if you have the shebang line you just need to do ./nameoffile
[06:36:14] <XXCoder> chmod +x yeah
[06:36:47] <XXCoder> then can run it directly with simply ./whatever
[06:37:10] <XXCoder> if its not marked exec you would need to use python to run it
[06:40:23] <XXCoder> hm I wonder if +x is a requirement for linuxcnc to be able to run it
[06:40:30] <XXCoder> doubt it but lemme test
[06:41:23] <XXCoder> permission denied
[06:41:38] <jthornton> yea it is
[06:43:38] <XXCoder> loaded fine here now
[06:44:58] -!- veek has quit [Quit: Leaving]
[06:48:05] <XXCoder> what error is you getting?
[06:50:12] <jthornton> linuxcnc.error: emcStatusBuffer invalid err=3
[07:02:49] <XXCoder> cant figure that one
[07:06:15] <jthornton> I assume you should be able to just show one piece in the tk window?
[07:06:23] <XXCoder> yeah
[07:06:40] <XXCoder> tooltip and world have to be grouped into that object be besides that yeah
[07:07:11] <XXCoder> so minium 4, some object, tooltip work, and result of collection of all 3
[07:09:31] <Tom_L> morning
[07:09:45] <XXCoder> hey
[07:10:00] <XXCoder> haltranslate might be required lemme try
[07:10:22] <jthornton> ok
[07:10:25] <Tom_L> 44�, Hi 39, Lo 22
[07:10:30] <Tom_L> cold is on the way again
[07:13:45] <jthornton> going to be pretty warm here today 62F
[07:16:59] <XXCoder> bleh! finally got it running
[07:17:12] <XXCoder> case of dumbass, apparently folder on desktop is a shortcut
[07:17:17] <XXCoder> so when I copied it to make test
[07:17:31] <XXCoder> well i was apparently modifing same folder no wonder it didnt work
[07:17:37] <XXCoder> so lemme test something
[07:18:06] <XXCoder> okay running fine
[07:18:11] <XXCoder> dont need any haltranslate
[07:20:19] <XXCoder> jthornton: http://dpaste.com
[07:21:11] <XXCoder> making something weird with it now. just dancing ball
[07:22:48] <jthornton> cool it finally works for me, prob don't need the pins yet I'll test
[07:23:07] <XXCoder> im checking if all 3 haltranslates can be assigned to single object lol
[07:25:51] -!- fragalot has joined #linuxcnc
[07:26:16] <fragalot> hey
[07:26:20] <XXCoder> hey
[07:27:21] <jthornton> ok I finally got what I needed just the code to display the base and it's only a few lines
[07:27:25] * fragalot needs to find an affordable ~40mm drill or long annular cutter to continue the part he's working on
[07:27:37] <fragalot> because screw going from 15mm up to 42mm with the boring head :P
[07:27:38] <XXCoder> yep very short
[07:27:55] <XXCoder> im still writing new ini almost done
[07:30:17] <XXCoder> some kind of error, no line drawing, or maybe sphere is too small. base is way too high so probably silly error
[07:30:21] <fragalot> shame forstner bits dont work on cast iron :p
[07:30:26] <jthornton> http://dpaste.com
[07:30:43] <XXCoder> super brief lol
[07:31:17] <jthornton> that's what I need for the docs super brief and to the point and most important it works!
[07:31:56] <XXCoder> btw using 3 haltranslates to single object apparently works. could see sphere move in all axis.
[07:33:18] <XXCoder> lol i tranplanted base not sphere no wonder places seemed swapped
[07:33:27] <jthornton> cool, paste that up when you get it done
[07:33:55] <jthornton> looks like firefox is forcing me to reboot lol
[07:34:14] <XXCoder> firefox is kinda broken all you need is close reopen firefox
[07:34:23] <XXCoder> sometimes have to wait few minutes
[07:34:26] <XXCoder> no reboot needed
[07:35:13] <jthornton> yea, I can't reboot right now anyway I have a terminal open running the coop automation
[07:35:55] <XXCoder> umm alpha dont work
[07:36:05] <XXCoder> ball should be 50% transparent
[07:36:20] <XXCoder> 10% I mean
[07:38:20] <XXCoder> http://dpaste.com
[07:38:25] <XXCoder> enjoy lol
[07:38:45] <XXCoder> I changed ini to have 600x600x600 volume machine
[07:38:57] <XXCoder> base is much larger than actual work volume
[07:39:07] <jthornton> are you running that from linuxcnc?
[07:39:21] <XXCoder> apparently if you group work and tooptip in such way it shares same spot it wont draw a line
[07:39:30] <XXCoder> I moved work from sphere to base
[07:39:56] <XXCoder> yeah sphere just moving around and drawing a line. its a 3d etch
[07:40:14] <XXCoder> etch a sketch 3d version lol
[07:40:44] -!- gloops has quit [Ping timeout: 244 seconds]
[07:44:55] <jthornton> is the sphere the red dot?
[07:46:28] <XXCoder> yeah
[07:46:34] <XXCoder> its pretty tiny
[07:46:49] <XXCoder> i'd make it larger if transparencies work
[07:46:57] <XXCoder> it dont seem to be case
[07:48:06] <jthornton> ok, I just need to make the axis connections in hal now
[07:49:51] -!- Inline has quit [Quit: Leaving]
[07:54:37] -!- gloops has joined #linuxcnc
[07:56:06] -!- weenerdog has joined #linuxcnc
[07:56:08] <weenerdog> good morning
[07:57:27] <XXCoder> hey hey
[07:58:03] <XXCoder> jthornton: bet it'd be fun to run a giant hilbert 3d grid with sphere vismach :P
[07:59:04] -!- Inline has joined #linuxcnc
[08:00:20] <weenerdog> thats something like i used to make fusion cry like a bitch. except it weaves over and under itself
[08:01:07] <weenerdog> but i got a plan. i was being stupid. i was making a height field instead of vector paths
[08:05:41] <jthornton> well I discovered more trickery and secret shit I hate to find if there is a file called sim_hardware.hal in the same directory it gets loaded even if it is not in the ini file...
[08:06:21] <jthornton> well maybe not dunno yet
[08:06:43] <XXCoder> hope not vismach is pretty conplex as is lol
[08:07:11] <XXCoder> I dont think can be more simpler and still axis than mine. well could have no base but hard to see movement otherwise lol
[08:07:18] <XXCoder> *still 3 axis
[08:07:21] <jthornton> lol I found out how it got loaded source sim_hardware.hal
[08:07:26] <jthornton> in the hal file...
[08:08:28] <XXCoder> it loads itself?
[08:08:36] <jthornton> should the red ball move when you run a file after connecting up the pins
[08:08:41] <jthornton> yea seems that way
[08:08:56] <jthornton> err no the main.hal file has that line
[08:09:01] <XXCoder> ahh
[08:09:19] <XXCoder> move as in move as commanded by linuxcnc? yeah
[08:11:04] <jthornton> I see the sphere.Xaxis and rest changing but the red ball does not move...
[08:12:01] <jthornton> http://dpaste.com
[08:12:48] <jthornton> http://dpaste.com
[08:13:19] <XXCoder> did you change test to sphere in hal and ini also?
[08:13:27] <XXCoder> ah you did
[08:13:52] <jthornton> ini?
[08:14:05] <XXCoder> yeah my mistake it has a name but its not critical
[08:14:10] <XXCoder> I think
[08:15:07] <XXCoder> MACHINE = sphere
[08:15:19] <XXCoder> line 13 or below version
[08:15:24] <XXCoder> dunno if its critical at all
[08:15:27] <jthornton> that should just be the name in axis
[08:15:32] <XXCoder> yeah
[08:15:56] <XXCoder> hmm strange that sphere dont move.
[08:16:18] <XXCoder> wonder if 2.8 changed so single object cant have 3 haltranslates?
[08:33:09] <XXCoder> jthornton: learned something new
[08:33:34] <XXCoder> tooltip must be group with lowest base object. it cant be collection with a collection and work
[08:34:13] <XXCoder> for example if I define sphere and cylinder, collection them together, then collection them again with tooltip it wont draw
[08:34:31] <XXCoder> would need to collection tooltip with say cylinder, then collection them with sphere
[08:39:18] <jthornton> can you paste that example?
[08:39:31] <XXCoder> nah it was abstract
[08:40:10] <XXCoder> i was curious if I could do 3 sphere, one only x, one xy motion and one xyz motion then attach tooltip to last one
[08:40:16] <XXCoder> drawing refused to work
[08:40:31] <XXCoder> I reverted it to single sphere like one you saw
[08:42:31] <jthornton> does the single sphere move for you?
[08:42:35] <XXCoder> yeah
[08:42:41] <XXCoder> in all 3 axis
[08:42:55] <jthornton> your using 2.7?
[08:42:57] <XXCoder> running it and manual moves dont work?
[08:42:58] <XXCoder> yeah

[10:31:49] <Getty> https://twitter.com you guys might lke this :D
[10:35:05] <fragalot> gloops: thanks :-) -- I'll need to figure out whether or not I can hold these in the schaublin though
[10:35:31] <fragalot> i've got morse adapters for it, but they require threads to pull it up into the spindle.. so doesn't work with those tails
[10:35:33] <jthornton> tapers on a couple look pretty beat up...
[10:36:13] <fragalot> jthornton: and the grinds look AWFUL too :P
[10:36:36] <jthornton> it did say assume they needed a regrind lol
[10:36:42] <fragalot> but if it stays below £50 or so I don't mind a few of them being unusable
[10:38:04] <fragalot> also, has anyone else ever noticed how ebay will sometimes NOT show you ANY items in one of their shops?

[10:46:42] <Tom_L> playin with a bouncin ball today ehh?
[10:47:00] <Tom_L> snow started a bit ago
[10:50:26] <fragalot> JT-Shop: do you have any experience with indexable drills?
[10:50:48] <fragalot> i'm wondering if they require more or less power than conventional drills, given their tendency to have less of a taper on the tip
[10:51:35] <Tom_L> we used some 3" ones on some Ti parts
[10:51:49] <tiwake> fragalot: less pushing more RPM
[10:51:54] <Tom_L> power wise i'm not sure
[10:52:09] <Tom_L> not in Ti :D
[10:52:12] <fragalot> tiwake: more curious whether the schaublin's 3kW spindle can push them or not
[10:52:13] <tiwake> well sure
[10:52:19] <fragalot> around 40mm dia
[10:52:26] <tiwake> fragalot: donno... I don't do metric
[10:52:38] <tiwake> :P
[10:52:41] <fragalot> about 1.6"
[10:53:04] <tiwake> insert drill or insert spade drill or something else?
[10:53:17] <tiwake> I've done lots with both
[10:53:20] <fragalot> either, open to suggestions
[10:53:26] <tiwake> what material?
[10:53:31] <tiwake> and volume
[10:53:32] <tiwake> heh
[10:53:35] <fragalot> cast iron
[10:53:44] <tiwake> oh pff whatever works
[10:53:45] <fragalot> pre-drilled at 15mm, 60mm deep
[10:53:54] <tiwake> use insert drill
[10:54:18] * fragalot => ebay
[10:54:19] <tiwake> spade drills don't like pilot holes
[10:54:24] <JT-Shop> fragalot: I think I have one somewhere lol, I guess the load depends on the insert
[10:54:33] <Tom_L> make sure you can get the inserts for them
[10:54:44] <fragalot> Tom_L: yea :P
[10:55:07] <tiwake> the problem with insert drills is you can't really change the size of the hole, so make sure you get exactly the size you need
[10:55:14] <fragalot> had fun yesterday roughing out the horizontal support bracket for the mill
[10:55:29] <fragalot> especially once you realize "hang on this thing has a horizontal spindle"
[10:55:30] <tiwake> spade drills give you a large-ish range of insert spade options
[10:55:36] <JT-Shop> Tom_L: just trying to understand vismach so I can make sense out of the documents
[10:55:43] <tiwake> but they hate pilot holes
[10:55:49] <fragalot> tiwake: I plan on boring to size, I just want to reduce the roughing time
[10:55:55] <tiwake> cast iron? its going to be butter
[10:56:07] <tiwake> so spin it up
[10:56:16] <fragalot> lathe isn't big enough
[10:57:01] <tiwake> fragalot: what is the volume?
[10:57:54] <fragalot> 5,5x5,5x2,5 "
[10:58:09] <tiwake> no, I mean volume of parts per week or month or whatever
[10:58:15] <fragalot> https://www.youtube.com <== that thing
[10:58:16] <fragalot> tiwake: one.
[10:58:37] <tiwake> just doing one? merf... just use a roughing endmill then
[10:58:45] <tiwake> and G13 it up
[10:58:50] <fragalot> manual machine
[10:59:13] <fragalot> but.. I can peck it out
[10:59:19] <fragalot> thanks for the suggestion
[10:59:40] <tiwake> there is no reason to use a $200 tool for making a 1.6" hole for one part
[10:59:42] <tiwake> lol
[10:59:51] <tiwake> unless you want to use it for other things
[11:00:18] <fragalot> they can be found used for far less, and don't wear out in the home shop.. ever :P
[11:01:20] <tiwake> do whatever you want... I'm just suggesting crap based on.. well... my experience with such tools
[11:01:39] <fragalot> but I didn't want to risk spending ~ €60 on one (plus inserts) if a 3kW spindle wouldn't run it
[11:01:45] <fragalot> hence asking about that in the beginning
[11:02:12] <tiwake> thats like 1.something hp?
[11:02:30] <fragalot> 4hp
[11:02:30] <tiwake> its cast iron, it will be fine
[11:02:49] <fragalot> sweet
[11:02:57] <tiwake> steel? more issues, but not horrible

[12:41:23] <ChunkyPuffs> Hey guys do you think I can do 6mm at a time with a 12mm 2 flute flat?
[12:41:35] <ChunkyPuffs> on wood
[12:41:41] <ChunkyPuffs> carbide
[12:42:05] <fragalot> depends on the wood & how rigid your router is, but.. absolutely.
[12:51:58] <gloops> id use a spiral cutter, depends on the wood, and your machine, like oak is a lot harder than pine
[12:52:51] <fragalot> i've found oak cuts a lot nicer
[12:53:33] <fragalot> (assuming sharp tool)
[12:55:47] -!- jbar has quit [Quit: Page closed]
[12:56:22] <gloops> oak does cut well yeah, ive found pine to be more variable, some cuts great, another piece doesnt
[12:57:11] <fragalot> yeah.. some days you get a piece with tight grain that works well, other times you get stuff with like 10mm growth rings
[12:57:25] <gloops> there is only one way to really know the outcome of a given speed and cut etc heh
[13:02:06] <ChunkyPuffs> streaming on https://twitch.tv again
[13:02:14] <ChunkyPuffs> so you can see the outcome of this horrendous experiment
[13:02:18] <ChunkyPuffs> hope I don't break the bit
[13:04:05] <ChunkyPuffs> just going to do it at 4mm per passes instead, to avoid potential horrendous behaviour
[13:04:16] <fragalot> Good luck :-)
[13:04:32] -!- DaPeace has joined #linuxcnc
[13:04:33] <gloops> i can show you a vid that proves the outcome...
[13:04:51] <gloops> but you try first ;)
[13:05:19] <fragalot> yea gloops but you were plunging with a cutter that wasn't designed to plunge :P

[13:09:37] <gloops> a flat bit needs slower feed

[13:13:34] <gloops> the dovetails are actually perfect, if i say so myself, no breakout or chipping

[13:25:52] <ChunkyPuffs> gloops, generally speaking, what needs to change as you get larger flat heads?
[13:26:02] <ChunkyPuffs> do you need to reduce the rpm? do you need to reduce the feedrate?
[13:27:37] <fragalot> ChunkyPuffs: typically you want to keep the chip per tooth the same, and the rpm optimal for the material & cutter combination you have
[13:28:21] <ChunkyPuffs> so feedrate stays the same fragalot ?
[13:28:28] <MarcelineVQ> which would be a good idea to use a calculator to determine
[13:28:31] <ChunkyPuffs> I'm not really advanced enough yet to know what chip per tooth is
[13:28:40] <fragalot> ChunkyPuffs: it should be one of the fields in fusion
[13:28:52] <ChunkyPuffs> My cnc doesn't have control over it
[13:28:55] <fragalot> chip per tooth == how much each tooth cuts away each time it spins around
[13:29:08] <fragalot> so if you lower the RPM, your feedrate goes down
[13:29:10] <ChunkyPuffs> you set the feedrate and speed, that's all I can adjust in my software
[13:29:14] <fragalot> if you increase RPM your feedrate goes up
[13:29:29] -!- DaPeace2 has quit [Quit: Leaving.]
[13:29:34] <fragalot> if you increase in diameter, your surface speed goes up, so you reduce the RPM to compensate
[13:29:51] <ChunkyPuffs> which in effect means lowering feedrate/
[13:29:58] <ChunkyPuffs> but you have to manually lower your feedrate ,right?
[13:30:19] <fragalot> if you don't have a CAM software to figure that out for you, yes.
[13:30:50] <MarcelineVQ> ChunkyPuffs, search "speeds and feeds" on youtube
[13:31:12] <fragalot> for wood, the range that you can work in is quite forgiving though
[13:33:36] <ChunkyPuffs> MarcelineVQ, I'm aware of the concept
[13:33:51] <ChunkyPuffs> so now I'm asking what exactly it is that I have to do for larger bits
[13:34:02] <ChunkyPuffs> speeds and feeds relates to material more than it does to the cutter
[13:34:19] <ChunkyPuffs> so a search result is about that more than what I want, which is info about the cutters
[13:34:41] <fragalot> carbide can take much higher feedrates, as it is more rigid, and can stand the heat better
[13:34:46] <gloops> the straight bits cant clear chips like a spiral cutter, you need to drop the feed/speed
[13:35:11] <fragalot> or an air blast
[13:35:12] <ChunkyPuffs> so would you say 20k RPM 1500mm/min is too much for a 2 flute flat head?
[13:35:38] <gloops> for a deep cut probably yes
[13:35:44] <ChunkyPuffs> 6mm per cut
[13:36:00] <fragalot> hit go & listen.. if it sounds wrong, it probably is
[13:36:13] <ChunkyPuffs> I'm not riskin a £20 bit on that
[13:36:14] <gloops> depending on the cutter youre looking at a mm or 2 per pass, for deep cuts slow it right down
[13:36:15] <ChunkyPuffs> yet
[13:36:26] <fragalot> ChunkyPuffs: so start slow
[13:36:37] <ChunkyPuffs> there's no such thing lol
[13:36:40] <ChunkyPuffs> you don't have time to react
[13:36:55] <gloops> 12ipm is not uncommon for pine you know
[13:36:58] <ChunkyPuffs> the cut either works or it doesn't, you either take it too far or you don't
[13:37:59] <gloops> try 750mm/min maybe 300mm for plunging
[13:39:15] <gloops> it wants to be cutting its way through, not smashing

[14:29:28] <gloops> got it cutting yet ChunkyPuffs
[14:30:44] <ChunkyPuffs> not quite gloops
[14:30:51] <ChunkyPuffs> I'm gonna try metal with a 3mm 1 flute
[14:31:02] <fragalot> before doing the wood thing?
[14:31:04] <ChunkyPuffs> I'm a bit tired though, been up 48hrs
[14:31:14] <ChunkyPuffs> yeah before doing the wood thing, I've had a few successful wood cuts before
[14:31:37] <ChunkyPuffs> I don't have access to a 6mm bit, or optimal stock for the wood though, so it's limiting, i have 4mm aluminum here
[14:31:54] <gloops> 3mm snaps very easily with metal lol
[14:32:26] <fragalot> alu is tricky
[14:32:38] <fragalot> do NOT let ANY heat build up around the bit
[14:32:40] <MarcelineVQ> it is, going to slow welds the chip to your bit
[14:32:50] <MarcelineVQ> and it gets worse from there
[14:33:19] <gloops> the perennial issue with routers and aluminium is spindle speed, they nearly all have high speed spindles which have little torque at low revs and risk overheating
[14:33:42] <fragalot> gloops: at the same time, a 3mm bit single flute calls for high RPM
[14:33:52] <fragalot> but, you are correct.
[14:35:21] <MarcelineVQ> on the plus side, it should be quite easy to find speed and feed charts for aluminum
[14:36:39] -!- jbar has quit [Quit: Leaving]
[14:39:47] <Tom_L> single flute on metal probably not the best idea
[14:40:20] <fragalot> Tom_L: works fine on alu
[14:40:39] <fragalot> ask datron if you have any doubts :P
[14:40:51] <Tom_L> meh, i believe you
[14:41:00] <Tom_L> i'd just rather have 2
[14:41:04] <MarcelineVQ> 1 and 2 flute are ideal for alu, afaik
[14:41:15] <Tom_L> some like 3
[14:41:20] <fragalot> Tom_L: 2 is fine, IF your machine can move fast enough to keep the chipload nominal
[14:41:31] <Tom_L> yeah
[14:41:31] <fragalot> and that is where a single flute comes in
[14:43:59] -!- jbar has joined #linuxcnc

[15:45:49] <XXCoder> Tom_L: yeah impressive as heck, that machine
[15:45:50] <Roguish> not sure about that. don't think so, need one of their boxes, i believe. about $70 now. check 'em out at least.
[15:46:21] <XXCoder> but yeah while vismach requires work object to be made and included, it doesnt do anything
[15:46:27] <tiwake> Roguish: because I'd like to have the service for the same phone number on my cellphone, and my cellphone does not run on iOS or android
[15:46:43] <XXCoder> you could add stock shape yourself but besides it being there there is no effect
[15:47:11] <Roguish> tiwake: that's beyond me. good luck. let us know how it works out.
[15:47:46] <XXCoder> I wonder if there was supposed to be input on stock size and it feeds to vismach so it could show it. even if it doesnt show cuts with good transparancy (which doesnt work) it would be quite effective
[15:48:06] <tiwake> Roguish: if its a regular SIP phone service, I can get whatever SIP client I want, cisco phones, whatever SIP client I want on windows or linux or whatever

[20:54:28] <MarcelineVQ> nah there's no mechanical parts inside, https://www.wonkeedonkeetools.co.uk
[20:54:35] <Tom_L> As the sliding jaw travels along the main scale, the rectangular plates align and misalign and the capacitance (the amount of electrical charge) between the plates changes. This sends a signal to a chip within the caliper, which generates the readings shown on the LCD display.
[20:54:59] <XXCoder> nice site reading
[20:55:46] <Tom_L> hah i got mine from google
[20:56:40] <XXCoder> capatence nice

[22:30:12] <Getty> So I think its stepper
[22:30:17] <Getty> cause it says STEPPER MOTOR 8-D
[22:30:24] <Getty> aehm STEPPING MOTOR so :D
[22:30:36] <Getty> i am no expert, tho :D
[22:31:09] <Getty> the bad part is, that i now noticed that a) i cant see the motor of the 2nd axis and b) there is only the Parallel Port as any output of the device at all
[22:31:18] <Getty> i feel trouble coming up
[22:31:40] <XXCoder> nice
[22:31:48] <Getty> nice?
[22:31:56] <XXCoder> finding out that its stepper
[22:32:00] <XXCoder> little bit of latency here
[22:32:17] <XXCoder> have you looked if there is electrics box anywhere in it, like under table
[22:32:34] <XXCoder> if not that dos box probably is directly controlling it
[22:32:51] <XXCoder> but then where do steppers get power as parallel port cant supply that much amps
[22:33:05] <XXCoder> sounds like wiring tracing in your future
[22:33:26] <Getty> they got a power of course
[22:33:32] <Getty> i mean thre is one power connector
[22:33:40] <Getty> wait a sec must find out how to make an album again on imgur
[22:33:53] <XXCoder> does it just go to psu?
[22:34:33] <Getty> https://imgur.com
[22:34:37] <Getty> here the album of the corner stones
[22:34:59] <Getty> that one motor i can see, the parallel port connector with nothing else around, the drill and the power connector
[22:35:08] <XXCoder> IO bet you electrics is under inside box]
[22:35:17] <XXCoder> you might have to lift and remove cover
[22:35:20] <Getty> well inside then, there is just plate under it
[22:35:27] <Getty> question
[22:35:28] <XXCoder> or top
[22:35:30] <Getty> do we really want that?
[22:35:53] <XXCoder> pictured your router table seem to have alum board with bolts on it?
[22:36:01] <Getty> yes
[22:36:05] <XXCoder> if so, just draw its orginial position on it and remove
[22:37:01] <XXCoder> and hope orginial designer was smart enough to design in maintanability
[22:37:19] <Getty> what you mean? https://i.imgur.com here the picture again
[22:37:29] <Getty> i feel like that box wasnt made to be opened
[22:38:02] <XXCoder> the BIG sheet of alim resting on extrude frame on bottom
[22:38:05] <XXCoder> alum
[22:38:14] <XXCoder> look around it see if anything is bolted on it
[22:38:25] <Getty> you mean under it?
[22:38:49] <Getty> let me see
[22:38:54] <XXCoder> lets picture it as collection of connected boxes, cover I am talking about is top of lowest box
[22:38:57] <XXCoder> also biggest
[22:39:21] <XXCoder> hopefully you will be able to just unbolt and remove cover
[22:40:39] <Getty> "unbolt"
[22:40:43] <Getty> how you unbolt at all?! :D
[22:41:01] <XXCoder> lemme download pic and paint on it a second
[22:42:49] <XXCoder> https://imgur.com
[22:43:06] <Getty> ok rearranged pictures and added 2 new ones: https://imgur.com
[22:43:20] <Getty> cause there is another connector i just realized not sure what it should be
[22:43:26] <Getty> and the bottom is pretty much solid bolted
[22:43:37] <XXCoder> yeah looks like it
[22:43:41] <Getty> XXCoder: yeah those are bolts, how you remove them?
[22:43:52] <XXCoder> its likely bolts to hold on drivers and such
[22:43:55] <XXCoder> bottom one
[22:44:02] <XXCoder> top looks like hex tools
[22:44:19] <Getty> cant we do something with the parallel printer?
[22:44:24] <Getty> i mean we do have the DOS stuff still :D
[22:44:30] <XXCoder> you'd have to look around and see if top has stuff on top of it
[22:44:42] <Getty> what you mean?
[22:44:43] <XXCoder> if not then cover should be easy enough to remove
[22:44:53] <XXCoder> anything on top being bolted to cover
[22:45:12] <Getty> i am confused i have no idea how many bolts are under the stuff
[22:45:21] <Getty> next to the fact that i do not know how to remove the construction on top
[22:45:30] <Getty> it seems pretty much like a blackbox-click-here-shit
[22:45:47] <XXCoder> what I mean is stuff on top connected to only sides or is there anywhere in middle also?
[22:46:20] <Getty> i am confused, sorry, english not native language, so i am getting confuse what you mean
[22:46:27] <XXCoder> can ypu take a picture, directly into front or back of machine in such way that gantry sides is to left and right?
[22:46:29] <Getty> you see in the pictures everything i can see more or less
[22:47:14] <Getty> i am unsure.... what you mean exactly for a direction here
[22:47:20] <Getty> you mean like into the flow?
[22:47:26] <Getty> like "being the plate"? :D
[22:47:56] <Getty> i doubt you see much, i mean i know there is not anything really beside the slides for the holder
[22:48:09] <XXCoder> your picture is downwards into top of machine
[22:48:21] <XXCoder> what I want is just picture of sides of machine
[22:48:39] <Getty> you see all the connectors that are on the sides
[22:48:46] <Getty> else the box is solid metal
[22:48:51] <Getty> in the pictures
[22:49:00] <Getty> 3 connectors, one for power, one for parallel port, one... other thing
[22:49:14] <Getty> oh you mean like if there are screws or something to remove it from there
[22:49:23] <Getty> ?
[22:49:36] <XXCoder> im not sure how to properly access the elctrics in box
[22:49:55] <Getty> i feel like my dad has never ever opened that thing
[22:50:01] <Getty> what can we do through the parallel port?
[22:50:17] <Getty> i mean is there probably a way to find out what machine and have some "driver" for it on LinuxCNC?
[22:50:29] <XXCoder> hard to say, maybe can reverse engineer pins and find what pin needs what data
[22:50:38] <XXCoder> if its even compitable with more modern cnc protocols
[22:50:52] <Getty> well we still have the DOS machine and can get more detailed information about what we have
[22:51:00] <Getty> independent of the not much that is standing on the machine
[22:51:03] <XXCoder> you can boot dos machine and get configuration info?
[22:51:10] <Getty> i hope! didnt tried yet
[22:51:25] <Getty> i could probably remove the harddisc best
[22:51:33] <XXCoder> hopefully it does have info
[22:51:35] <Getty> and just attach it via some bay and access it via linux
[22:51:59] <XXCoder> if its old enough it might use some weird filesystem but yeah
[22:52:07] <Getty> its a DOS
[22:52:12] <Getty> so i know what filesystem ;)
[22:52:16] <Getty> FATFS
[22:52:17] <Getty> ;)
[22:52:18] <XXCoder> fat16 likely yeah
[22:52:27] <Getty> it actually doesnt matter which fat
[22:52:32] <Getty> all the fats are totally compatible
[22:52:40] <XXCoder> yay we all like fat ;)
[22:52:51] <Getty> YOU KNOW I'M FAT, I'M FAT, YOU KNOW IT!
[22:53:00] <XXCoder> do you have PATA connector on your pc?
[22:53:03] <XXCoder> sata nowdays
[22:53:09] <Getty> i dont have yet any PC at the room
[22:53:20] <Getty> i doubt the harddisc is sata ;) its proably IDE
[22:53:30] <XXCoder> yeah ide uses PATA
[22:53:30] <Getty> but i got some IDE2USB thing somewhere or i buy one
[22:53:35] <XXCoder> not bad
[22:53:58] <Getty> but that also simplifies the computer situation a bit
[22:54:11] <Getty> that i just need a parallel port at first before i buy any actual I/O card
[22:54:18] <XXCoder> yeah hopefully it has list of pins and what data it expects
[22:54:34] <XXCoder> and hopefully its a controller linuxcnc can run
[22:55:04] <XXCoder> if not you would need to replace drivers and stuff in machine
[22:55:34] <XXCoder> maybe MESA ethernet or something, as well as whatever stepper drivers that can run yours
[22:55:47] <XXCoder> your steppers has voltage and amp required?
[22:55:56] <Getty> i hope i dont need to open that box cause i will never be able to close it again
[22:56:07] <Getty> https://i.imgur.com
[22:56:20] <XXCoder> 4v 1a wow pretty small
[22:56:36] <XXCoder> 1.8 degree per step thats very typical
[22:56:37] <Getty> https://i.imgur.com
[22:56:40] <Getty> and thats the drill
[22:56:46] <Getty> i got a complete set of drills actually
[22:56:53] <Getty> got at least 3 other PROXXON packages
[22:57:10] <XXCoder> drill is powered on and off manually or machine does it?
[22:57:28] <Getty> there is a switch at it, probably manually
[22:58:16] <XXCoder> im looking up tb6600 stats
[22:58:36] <XXCoder> 5v, 0.5a to 3.5a
[23:00:34] <XXCoder> anyway first thing is make a disk image of your old dos systenm
[23:00:43] <XXCoder> need backup in case it decides to die
[23:01:05] <XXCoder> it may well have docs as well as program to run it
[23:02:06] <Getty> yeah sure, it is a common software he used with some configuration file for the setup
[23:02:14] <Getty> some very old DOS stuff
[23:02:23] <XXCoder> indeed. that configure file is what you want
[23:02:23] <Getty> so i am very certain we will get results
[23:02:40] <XXCoder> hopefully its readable, or program can read and have gui for displaying said settings.
[23:03:08] <Getty> else we just hammer the parallel and see what happens :D
[23:03:33] <XXCoder> lol risky
[23:03:57] <XXCoder> could send axis signal to one pin a time
[23:04:04] <XXCoder> but I dont know how risky it ius
[23:04:27] <XXCoder> expecially since you need axis enable pin also if it has such thing also
[23:04:33] <Getty> if i remove the drill there cant be actually much happening
[23:05:45] -!- Tom_itx has joined #linuxcnc
[23:06:08] <XXCoder> yeah just be careful and make sure all axis is in middle of position range
[23:06:25] <XXCoder> so you can jog it small distance see if it works
[23:06:39] <XXCoder> but honestly reverse engineering first likely make job so much easier.
[23:07:01] <Getty> well all steps at a time! :D
[23:07:15] <Getty> i also need for sure get a computer for there... still tiggling if i should get that T30! :D
[23:08:29] <Getty> i assume i shouldn't use parallelport via USB, or?
[23:08:45] <XXCoder> usb cant do realtime
[23:09:33] <XXCoder> cpu being too busy can "freeze" usb when you hit e-stop and want machine to stop now
