[00:02:54] <pink_vampire> one part is done!
[00:03:23] <pink_vampire> 5 more to go..

[00:05:11] <Tom_L> mine are too
[00:05:18] <Tom_L> gotta sand the tab off

[00:07:45] <pink_vampire> just put them on a rod with washer and nut at the end and finish on the lathe.
[00:07:54] <pink_vampire> one pass clean all
[00:09:43] <Tom_L> thought about that but i don't have a 5mm bolt handy
[00:10:31] <Wolf__> 10-32 should work
[00:11:45] <pink_vampire> it is just a cap, you can even back press it with the tailstock
[00:30:11] <pink_vampire> 4 parts to go..

[05:25:55] <veek> what's the difference between a 4 stroke 2 wheeler petrol engine and a tractor/tiller engine.. i was looking at some specs and the tiller has Displacement (Swept Volume) 631 cu.cm whereas the 2-wheeler has ngine Displ. : 87.8 cc but SUPPOSEDLY it produces 5 bhp of power at 6500 rpm and the tiller is rated at 9hp..
[05:26:48] <veek> the power's almost comparable but the displacement's hugely different

[08:20:39] <jdh> why did you open it?
[08:22:15] <Loetmichel> it should go into a steel inclosure.. i think i get a different one out of the stash ;)

[08:34:00] <Loetmichel> Rab: indeed!
[08:35:24] <Rab> Oh, I guess they forced it in backwards then?

[11:15:49] <robotustra> question: does anybody know how to get tool path coordinates from interpreter of rs274ngc without execution the command?
[11:18:49] <cradek> I don't understand your question, can you say more?
[11:19:47] <robotustra> let say I open gcode file and give and I what to get the trajectory of the tool.
[11:20:59] <robotustra> rs274ngc interpreter can read and execute this code, but I would like to get a whole trajectory before execution to draw it in OpenGL view window
[11:22:05] seb_kuzm1nsky is now known as seb_kuzminsky
[11:22:11] <robotustra> I didn't find a function which parse gcode file line by line and return the trajectory coordinates in the interpreter
[11:22:40] <robotustra> where I can get trajectroy coordinates from without actual running of the code?
[11:23:02] -!- tachoknight has joined #linuxcnc
[11:23:23] <cradek> are you aware that AXIS already does this exactly?
[11:24:01] <cradek> you could look at that, or perhaps you should look at the standalone interpreter, which is the program named rs274
[11:25:35] <robotustra> I read a doc about rs274ngc, but it has NO function to return position coordinates
[11:26:49] <cradek> but it prints the moves to stdout
[11:26:57] <robotustra> and I don't want to make my own interpreter of gcode because it's 1) too big (>12000 lines)
[11:27:16] <HighInBC> no need to interpret every line at once
[11:27:37] <robotustra> cradek, does it prints while execute?
[11:28:02] <robotustra> I want to draw trajectory BEFORE I execute a single line of code
[11:28:26] <cradek> do you know AXIS already does this?
[11:28:43] <hazzy-m> robotustra: https://github.com
[11:28:53] <robotustra> it does it in python. I would like to do it in c++
[11:30:04] <robotustra> I need c/c++ api to do this
[11:30:17] <robotustra> not python
[11:30:58] <hazzy-m> Look at how the python implementation does it, that will at least give you an idea of what you need to do in c++
[11:31:04] <robotustra> If I can just call interpreter line by line and get all coordinates without actual execution it wil be ok
[11:31:40] <HighInBC> is there a "dry run" mode?
[11:31:43] <robotustra> I already have an idea, I suspect that this c/c++ api already exist in the heap of the code
[11:32:05] <robotustra> HighInBC, where to look at this?
[11:32:14] <robotustra> probably
[11:32:37] <HighInBC> I dunno

[11:35:46] <robotustra> hazzy-m, it means that gcode reader reads only motion g-codes?
[11:36:06] <robotustra> like feed, arcfeed and traverse?
[11:38:14] <hazzy-m> No, it reads all the lines, there are also dwel, toolchange, rotaryindex and others, can't remember the exact names, its been a while since I played with it
[11:39:42] <robotustra> wait a minute, it looks like interpter can do either execution of just printing of information
[11:39:50] <robotustra> Igo back to reading
[11:39:59] <hazzy-m> That python code is using the python interface for the rs274 interpreter, so if you look at how that is implemented you should have a very good I idea what you need to do
[11:40:34] -!- jerryq has quit [Ping timeout: 240 seconds]
[11:40:41] <hazzy-m> Yes, you can use it just to spit out info
[11:40:57] <robotustra> hazzy-m, why I should read python code if there is original interpreter written in c++ code + it's well documented?
[11:41:51] <robotustra> and I'm going to use c/c++ api directly
[11:42:24] -!- chupacabra has joined #linuxcnc
[11:42:37] <robotustra> python is smoking aside, I don't want to touch python even with 10 ft stick. :)
[11:43:12] <hazzy-m> reading the python code might give you a hint as how you can use the interpreter ...
[11:43:45] <robotustra> how to use interpreter is written in the document in English
[11:43:56] <robotustra> https://ws680.nist.gov
[11:45:48] <robotustra> I have to read "stand alone interpreter" chapter

[12:49:48] <fragalot> JT-Shop: glad it works :D
[12:50:20] <fragalot> miss0r: My inner eye?
[12:50:34] <miss0r> isn't that a term? :D
[12:50:39] <fragalot> no :P
[12:50:41] <miss0r> :D
[12:50:55] <fragalot> miss0r: what i've mostly been wondering is how the hell i'm going to rigidly mount the read head on the Y given that there's no real flat surface..
[12:50:56] <miss0r> its like imagining pictures in your head.
[12:51:05] <fragalot> on the RF45 I made a subplate with 3 setscrews to align it
[12:51:14] <fragalot> but i'm not sure if I want to go that route again
[12:51:18] <miss0r> fragalot: Didn't we somehow cover this on the video tour?
[12:51:24] <miss0r> I can't remember the conclusion
[12:51:25] <fragalot> miss0r: we only covered position :P
[12:51:46] <miss0r> I'd need another tour or extensive amounts of pictures
[12:52:35] <fragalot> miss0r: https://media.exapro.com
[12:53:18] <fragalot> the proper place to put it would be on the right of that clamp
[12:53:52] <miss0r> yeah. that is what we talked about, yeah
[12:54:23] <fragalot> so the rail is easy.. just use that brown strip that's perfectly square to mount it
[12:54:34] <miss0r> I would probally make a block of steel with two bolts to attack it, and three set screws; two at the bottom & one at the top
[12:54:47] <fragalot> so the same way I did it on the RF45 then
[12:54:48] <miss0r> for ajustment
[12:54:57] <miss0r> basically, yeah
[12:55:05] <fragalot> I guess it did work well, and i'm expecting less than 1cm of bondo on this machine :P
[12:55:56] <miss0r> bondo?
[12:56:23] <fragalot> body filler
[12:56:30] <miss0r> hehe
[12:57:05] <miss0r> the RF45 was basically bodyfiller with some cast iron reinforcements inside :D
[12:57:15] <fragalot> I played around with a euromac FX punch today
[12:57:23] <fragalot> blimmin' nice machine, that
[12:57:32] <miss0r> hehe :D

[12:57:46] <miss0r> I fell in love with a small okuma CNC lathe today :-/
[12:58:12] <miss0r> it *only* has a footprint the size of my maho
[12:58:24] <miss0r> alas... impossible love
[12:58:27] <fragalot> xD
[12:58:37] <miss0r> but it was just so damn cheap!
[12:58:43] <fragalot> ZX, not FX*
[12:58:49] <fragalot> miss0r: until you add the Schunk chuck
[12:59:58] <miss0r> it already came with a röhm chuck. both 3 and 4 jaw
[13:00:07] <fragalot> no comparison
[13:00:09] <miss0r> rotary tools damnit !
[13:00:23] <miss0r> two x rotary tools

[13:00:51] <fragalot> just enough to make you realize what you're missing
[13:01:11] <fragalot> :D
[13:01:20] <miss0r> :'( *sob*
[13:01:30] <fragalot> CNC lathes only really get interesting once you start with 8 axis machines
[13:01:35] <miss0r> if I had the room to fit it, I would've bought it on the spot
[13:01:46] <fragalot> quicktech has some really neat affordable compact ones that i've run in the past
[13:01:51] <miss0r> nah. I would be pretty happy to own a two axis cnc
[13:02:56] <miss0r> This was an okuma Space Turn LB something. They only wanted 8k eur for it
[13:03:06] <fragalot> pocket change
[13:03:12] <miss0r> I'm not quite over it yet...
[13:03:15] <fragalot> xD
[13:03:22] <miss0r> Reality kicked in, and told me I had to turn it down
[13:03:23] <fragalot> so. no GLS delivery note yet
[13:03:39] <miss0r> the tracking info still says it is in Denmark...

[13:03:56] <miss0r> Tomorrow I will call them and tear them a new one
[13:04:17] * fragalot nod
[13:04:31] <fragalot> speaking of tearing a new one
[13:04:39] <fragalot> do you know where I could get some covers for my Z ways
[13:04:55] <fragalot> I tried using a rubber flap but with the way the Y moves that's just no good
[13:05:12] <miss0r> Can you do me a favour, and go put 22ish screws in a piece of wood, and take them out again, so I do not feel I've put all those screws in for no reason ? :)
[13:05:28] <miss0r> what are you thinking? harmonica ones?
[13:05:52] <fragalot> either harmonica, or stainless ( ones that overlap like the original
[13:06:31] <fragalot> er, like the deckels
[13:06:49] <fragalot> i'm not sure if schaublin ever bothered with way covers
[13:07:37] <fragalot> at least there's certainly zero provision for it
[13:07:38] <miss0r> hmm.. Looking, one sec. But if I can find it, it will be at a danish seller. And our luck with shipment isn't realy that great
[13:08:33] <fragalot> also - I think my whim purchase of a tschorn 3D taster may have been optimistic
[13:08:49] <miss0r> You should've gone for haimer :)
[13:08:50] <fragalot> because the table has to be all the way down and it /BARELY/ clears the vise xD
[13:08:57] <miss0r> :D
[13:09:21] <fragalot> I wish I could 've found a direct BT30 one that wasn't €600
[13:09:31] <miss0r> fragalot: https://industrikomponenter.dk
[13:09:38] <miss0r> Its all in danish :D but they got what you need
[13:10:12] <miss0r> https://industrikomponenter.dk
[13:10:40] <miss0r> 1) http://industrikomponenter.dk
[13:10:45] <fragalot> i'm wondering how the hell I can actually mount bellows correctly
[13:10:54] <miss0r> 2) http://industrikomponenter.dk
[13:11:15] <fragalot> the fact that the Y is on top of the machine, and the XY assembly moves sideways does not make it straightforward
[13:11:30] -!- homicdlbrainiac has joined #linuxcnc
[13:11:32] <miss0r> Nope. I guess you'll just have to clean it often :D
[13:11:40] <fragalot> :D
[13:12:33] <miss0r> Mill alot of cast iron with & use the airgun often. Then you will be forced to clean it :D Easy
[13:13:09] <fragalot> :P
[13:13:32] <miss0r> Nice, they also have leadscrew covers: http://industrikomponenter.dk
[13:13:33] <fragalot> I also need to make a pan for it
[13:13:35] <miss0r> I did not know that
[13:13:41] <fragalot> because flood coolant atm is ... well, a mess.
[13:13:52] <miss0r> That comes as a surprise :P
[13:13:54] <fragalot> and a huge waste as 80% of it goes on the floor
[13:14:29] <fragalot> (it runs down the vertical Y table slots, onto the Z handwheel & floor on both sides of the machine)
[13:15:10] <miss0r> That sounds less than ideal
[13:15:18] <fragalot> Quite.

[13:17:29] <miss0r> "vegan alert" :D
[13:17:48] <fragalot> ha
[13:17:54] <fragalot> I like the pet name he's got
[13:18:10] <miss0r> "Skattebasse" ?
[13:18:13] <fragalot> because if you interpret it in flemmish it means "fart berry"
[13:18:20] <miss0r> hehe
[13:18:41] <miss0r> Its basically 'sweet heart'
[13:18:49] <fragalot> (and yes we actually use that as an endearing term sometimes tooÃ
[13:19:03] <miss0r> haha, of course you do :D
[13:22:25] <miss0r> I have an issue with a machine I am working on. It mixes air into the oil, almost making it foamy
[13:23:06] <miss0r> reasonable deduction; air is getting into the system. And because it is a medium pressure system, it must get in there before the pump.
[13:23:06] <fragalot> use an oil that doesn't have a saponifier in it
[13:23:53] <miss0r> Well, by the time the oil gets back to the resevoir, its returned to its clear state
[13:24:32] <miss0r> before the pump theres a pipe going into the resevoir, through a filter & into the pump. and I cannot for the life of me find a hole or bad joint ! :-/
[13:25:23] <miss0r> Its not a real issue, as the oil is still quite viscous(?) & lubricates like it is supposed to. It just looks wrong
[13:26:10] <miss0r> it probably pisses me off more than it should :]

[13:28:09] <miss0r> you can
[13:28:19] <miss0r> but it needs the right scale in there for it to make sense :)
[13:28:36] <fragalot> relative measurement is fine for me :P
[13:29:00] <fragalot> mix 'known good' amount, read it's ... salinity ... and use tha as a baseline

[13:57:13] <fragalot> kitchen
[13:57:42] <miss0r> We actualy have a very small kitchen :D so not
[13:58:19] <fragalot> office
[13:58:40] <fragalot> livingroom
[13:58:46] <fragalot> car
[13:58:48] <miss0r> Quite likely where they will end up(office)
[13:59:04] <miss0r> hehe car.. Not a good idea to have non lockable drawers in a car..
[13:59:05] -!- P1ersson has joined #linuxcnc
[13:59:38] <fragalot> easy fix
[14:00:13] <miss0r> I also would like to be able to access it *sometimes* -> less easy fix than what you were thinking about :P
[14:00:32] <fragalot> I was just thinking a simple pin & 2 washers
[14:00:43] <fragalot> slide pin in, all drawers locked.. remove pin, all drawers open
[14:00:44] -!- homicdlbrainiac has quit [Quit: Leaving]
[14:01:14] <miss0r> okay - that is pretty easy. But still a minimum of 4 per drawer system
[14:01:31] <miss0r> four columns of drawers.
[14:01:51] <fragalot> or 2 if you use a wide strip
[14:02:31] <miss0r> huhm.. Not a bad idea actualy. You know I hate to give it to you :D
[14:02:38] <fragalot> :P
[14:06:08] <miss0r> my wrist watch just fell into 9 pieces.. wtf
[14:06:37] <miss0r> the band broke off and the watch fell to the ground sheering two additional pieces off the band + alot of loose pins
[14:06:52] <fragalot> oops
[14:07:24] <miss0r> It had it at the watch repair man last week to have the pins checked!
[14:07:41] <miss0r> I felt they were getting loose, and he told me they were fine and not worry about it !
[14:07:43] <miss0r> bah!
[14:08:15] <miss0r> He thought he would get this repair job :D but jokes on him, I'll take the next one down the road

[17:08:35] <pink_vampire> i need help with feed and speed for drilling
[17:10:22] <Tom_L> material?
[17:10:37] <pink_vampire> 2024-t3
[17:11:40] <Tom_L> https://www.chipblaster.com
[17:11:58] <Tom_L> wait.. that's not for drills
[17:12:39] <Tom_L> http://www.morsecuttingtools.com
[17:12:54] <pink_vampire> problem #2 where is the tap & drill set???
[17:13:08] <Tom_L> what do you mean?
[17:13:38] <Tom_L> depends how you program them
[17:13:58] <pink_vampire> i can't find my tapping set
[17:14:06] <Tom_L> set to the point and add .3 * diameter for the point
[17:15:50] -!- FinboySlick has quit [Quit: Leaving.]
[17:16:53] <pink_vampire> i want to see what drill diameter i need, but i need to find the tapping set first.
[17:17:28] <pink_vampire> ok, found it!
[17:17:37] <Tom_L> the .3 is for a 118 deg point
[17:18:04] <Tom_L> also depends on the type of tap
[17:18:11] <pink_vampire> the screw is 8-32, and the drill is #29
[17:18:14] <Tom_L> high helix is recomended for cnc
[17:18:29] <Tom_L> how deep?
[17:18:41] <pink_vampire> I'm going to tap by hand.
[17:18:52] <Tom_L> wtf for?
[17:18:53] <pink_vampire> i only need to drill it
[17:19:02] <Tom_L> you got linuxcnc for that !!
[17:19:09] <pink_vampire> for the servo spindle belt holder
[17:19:40] <Tom_L> for the drill depth figure the depth you want and add .3*diameter for the point
[17:19:49] <Tom_L> set the drill off the point like you would a mill cutter
[17:19:57] <pink_vampire> the hole depth is 25mm
[17:20:10] <Tom_L> 1"
[17:20:19] <Tom_L> no tap will tap that deep
[17:20:33] <Tom_L> not that size
[17:21:02] <pink_vampire> the tapping is 3/4" deep
[17:21:13] <Tom_L> so peck drill the hole
[17:21:16] <pink_vampire> but how do i drill it?
[17:21:24] <Tom_L> what do you mean?
[17:21:44] -!- phiscribe has joined #linuxcnc
[17:21:51] <Tom_L> G83
[17:22:17] <pink_vampire> what rpm, Z feed, in what depth to peck it?
[17:22:28] <pink_vampire> the drill is hss
[17:22:34] <Tom_L> you can peck the drill diameter and be safe
[17:22:50] <Tom_L> 800-1000 rpm probably
[17:23:07] <Tom_L> figure your chip load from that
[17:23:18] <pink_vampire> I can't go that slow
[17:23:34] <Tom_L> minimum?
[17:23:39] <pink_vampire> 20K
[17:23:44] <Tom_L> good luck
[17:23:54] -!- phiscribe_ has quit [Ping timeout: 244 seconds]
[17:23:55] <Tom_L> make sure you spot the holes
[17:24:00] <pink_vampire> i can go up to 60K
[17:24:14] <Rab> With HSS?
[17:24:20] <pink_vampire> it will be almost like EDM
[17:24:36] <Rab> I mean, friction drilling is a thing...
[17:24:46] <Tom_L> 2024 is kinda gummy isn't it?
[17:25:02] <Tom_L> better run a test hole
[17:25:15] <pink_vampire> much harder then 6061
[17:25:18] <Rab> Are you using coolant?
[17:25:26] <pink_vampire> baby oil
[17:25:34] <Tom_L> i'd hope so if he's goin 1" deep
[17:25:38] <Tom_L> 25mm sry
[17:26:19] <Tom_L> you may end up burning up the drill at those speeds
[17:26:31] <Tom_L> i've never tried it with a high speed spindle
[17:27:41] <pink_vampire> at least is not titanium that can self ignite
[17:27:57] <Tom_L> you want .001 - .002" per revolution
[17:28:21] <Tom_L> so figure your minimum rpm ( it will have no torque at that speed )
[17:28:33] <Tom_L> and adjust your feed to that
[17:28:43] <Tom_L> use the drill diameter as the peck depth
[17:28:57] <Tom_L> approx

[18:27:38] <pink_vampire> so don't drill with 3.4mm hss drill at 60K rpm, it will make some noise

[22:38:16] <trentster> Just built a new cnc router machine that uses 2 steppers for Y axis, any opinions on the best way to use proxomity switches to home each side square?
[22:39:32] <trentster> I already have a working config from an existing machine, but I see there is a lot of ways to do it with dual. I am using 2 seperate drivers, 1 for each of the steppers.
[22:40:14] <hazzy> trentster: Are you using 2.7 or 2.8~pre? You really need to be using 2.8 to do it right ..

[23:00:49] <pink_vampire> trentster: just use the same signal to drive both motors
[23:02:41] <trentster> Hazzy, I am not sure the exact version, I havent touched my machine in about 2.5 years it must be 2.7.x something
[23:09:10] <pcw_home> Yeah, the right way is to use 2.8 and have 2 stepgens and 2 joints for Y (to allow proper gantry homing)
[23:14:58] -!- methods_ has quit [Ping timeout: 252 seconds]
[23:15:11] <trentster> pcw_home: is 2.8 a must have for this?
[23:15:24] <trentster> I dont even see 2.8 on the main project page
[23:15:40] <trentster> isn't 2.7 current (stable)
[23:16:00] <CaptHindsight> trentster: it's the version that has support for 2 motors on one axis
[23:16:10] -!- methods_ has joined #linuxcnc
[23:17:07] <pcw_home> If you want to do proper gantry homing 2.8 is better (with 2.7 there's a somewhat kludgy workaround (the gantry component)
[23:18:04] <pcw_home> 2.8 is the development version "master"
[23:20:48] <trentster> Damn…guess I will have to upgrade. I am loathe to touch it tbh, its been working flawlessly for 2.5 years without a hiccup.
[23:21:14] <trentster> Is recommended route to backup config and wipe and reload 2.8 from scratch using a bootable iso?
[23:23:49] <pcw_home> If its flawless I would leave it alone, If you need proper dual motor dual switch gantry homing 2.8 is your best bet
[23:25:55] <trentster> sigh…
[23:26:06] <trentster> Thanks guys (scratches head)
[23:38:12] <Kevin`> turn the current down, slam it into the end stops, and turn it back up. only sort of kidding :)
