[00:00:08] <zeeshan> 1982 i think
[00:00:11] <zeeshan> lemme check
[00:01:16] <zeeshan> 1984
[00:01:52] -!- sylphiae [sylphiae!~sylphiae@50-200-5-117-static.hfc.comcastbusiness.net] has joined #linuxcnc
[00:01:55] <zeeshan> im going to take it all apart
[00:01:58] <zeeshan> and clean up everything
[00:02:11] <zeeshan> from the looks of it, i just only need a 5i25
[00:03:17] <PCW> drives may need work or replacement if they are original 1982 models
[00:03:44] <PCW> you will find out when you dive in :-)
[00:03:59] <zeeshan> yes
[00:04:04] <zeeshan> btw do i need a 7i77
[00:04:12] <zeeshan> to have analog input
[00:04:34] <zeeshan> thats what i noticed from the 5i25 manual
[00:04:51] <PCW> for analog velocity mode drives with quadrature feedback, yes a 7I77 is appropriate
[00:04:55] <zeeshan> 7i75 is a basic breakout board, 7i76 is a step/dir bbob, 7i77 is one
[00:04:57] <zeeshan> ok
[00:05:10] <zeeshan> well you need analog velocity mode
[00:05:17] <zeeshan> thats the only way you can truly say you have closed loop :P
[00:05:57] <PCW> check what you have before choosing retrofit equipment
[00:06:25] <PCW> 1982 may be old enough that the motors have resolvers
[00:06:33] <zeeshan> well if thats the case
[00:06:38] <zeeshan> ill still buy a quadrature encoder
[00:06:49] <zeeshan> i really want feedback right into linuxcnc
[00:07:26] <PCW> resolvers can be used but the interface equipmemt costs more
[00:08:24] <CaptHindsight> zeeshan: I'd paint it metal flake green and call it the Hulk
[00:08:32] <zeeshan> haha
[00:08:39] <zeeshan> the guy was really nice
[00:08:43] <zeeshan> materials engineer by education
[00:09:00] <zeeshan> but he runs an aerospace machineshop/design
[00:09:09] <zeeshan> does some work for canadian space agency
[00:09:52] <zeeshan> he was biased though
[00:10:03] <zeeshan> said mach 3 is better than emc haha

[01:27:02] <Jymmm> ;)
[01:27:36] <jdh> you kinda set yourself up there.
[01:27:42] <Jymmm> "I swear... it was <----------- THIS BIG ----------->"
[01:28:07] <jdh> only thing left that makes sense would be "*Jymm blows"

[01:31:25] <Jymmm> Windows is great! I made a living off all the fubarness for over 20 years =)
[01:31:48] <Jymmm> Windows... the most profitable virus ever known.
[01:33:05] <LeelooMinai> I like my Win8 - stable as a rock for few years now
[01:33:52] <Jymmm> No OS is stable.
[01:34:06] <PetefromTn_> Speaking of windows
[01:34:07] <Jymmm> Not even linux. Maybe flavors of BSD, but that's about it.
[01:34:26] <LeelooMinai> Doesn't crash on me = stable in my book
[01:34:47] <Jymmm> lol
[01:35:09] <jdh> lowered expectations help.
[01:35:13] <PetefromTn_> I have windows 8 and while it has media player to play music it does not have media center which allows you access to graphic equalizers and other useful schtuff.. Anyone got a workaround?
[01:35:17] <Jymmm> LeelooMinai: Just curious, what's your longest uptime?
[01:35:24] -!- now7777 has quit [Ping timeout: 255 seconds]
[01:35:39] <LeelooMinai> Jymmm: I use it as my main desktop machine, not a server.
[01:35:48] <Jymmm> LeelooMinai: so?
[01:36:11] <Jymmm> I can make any os "stable" if I restart it hourly.
[01:36:31] <Connor> I had a windows 2003 Server up for over 3 years.. only reason wasn't longer is I had to reboot it because of a program upgrade the required a reboot.
[01:36:35] <XXCoder> just read that linux is considering splitting for desktop and server
[01:36:38] <LeelooMinai> Jymmm: I start it in the morning, and power off when I go to slep.
[01:36:42] <XXCoder> because they have very different demends.
[01:37:06] -!- mhaberler has quit [Quit: mhaberler]
[01:37:15] <Jymmm> Connor: I hat a NT4 box uptime of 99.9% for 4 years, till I updated IE on it =)
[01:37:16] <Connor> XXCoder: That's a bunch of BS. That would be the worst thing they ever did.
[01:37:22] <LeelooMinai> Jymmm: And this is in line with my statement that use proper tool for proper job - which in this case is desktop machine:)
[01:37:33] <Jymmm> Connor: the 0.01% was a power fialure.
[01:37:37] <XXCoder> dont ask me, ask em Connor :)
[01:37:53] <Connor> I've read they stuff.. I'm just saying.. I don't think it'll happen..
[01:37:57] <Jymmm> LeelooMinai: Yeah, uh huh.
[01:38:06] <jdh> I reboot my linux and vms boxes every spring (we have a site-wide power outage every year)
[01:38:08] <XXCoder> their?
[01:38:15] <Jymmm> jdh: lol
[01:38:16] <PetefromTn_> anyone? bueler?
[01:38:29] <jdh> Pete: it's there, not part of media player though
[01:38:35] <Connor> XXCoder: Yes.. Their. sorry.
[01:38:40] <PetefromTn_> where?
[01:38:49] <XXCoder> np, was unsure exact meaning lol
[01:38:49] <Connor> right arm killing me.. Pinched nerve..
[01:38:55] <Connor> in the shoulder and neck...
[01:39:15] <Connor> Been in bed most of the day.
[01:39:22] <jdh> Pete: either an app for your sound chip or just look for the system volume thing (I don't use 8 so I dunno)
[01:40:05] <jdh> if I had to turn my winbox at work off every day, I'd lose an hour a day.

[01:40:21] <Jymmm> heh
[01:41:10] <Connor> I have a problem with my linux machine.. X Locks up.. hard.. It's GPU problem.. I can remote into the machine via SSH.. but.. only way to fix it is to reboot it.
[01:41:33] <jdh> can't restart X?
[01:41:39] <XXCoder> sounds like configuration issue for x
[01:41:47] -!- mhaberler [mhaberler!~mhaberler@extern-174.stiwoll.mah.priv.at] has joined #linuxcnc

[01:43:02] <jdh> what happens when you kill it?
[01:43:25] <Connor> Nothing.. no screen activity at all.. the GPU is crashed.
[01:43:42] <Connor> Normally happens if I watch videos..
[01:43:54] <Connor> or have heavy graphics going on.

[01:47:15] <jdh> I would think that you would have 4-20 graphics cards laying around.
[01:47:35] <Connor> I haven't looked at it in a while.. probably need to.
[01:47:47] <XXCoder> that is why I do annual dust cleaning

[01:48:00] <XXCoder> my pc is at 8th cleaning and should have 9th soon but been delaying it lol
[01:48:47] <Connor> Quad Core i7 2.8mhz machine with 12GB Ram and 2TB Hard Drive. ATI Dual Video card.
[01:48:50] <Connor> not a bad machine.
[01:49:51] <XXCoder> when humans used rocks, my pc was very top end pc
[01:50:11] <XXCoder> thats why its still pretty darn awesome years later
[01:50:27] <Connor> This one is at least 3 years old now.
[01:50:44] <Connor> I was running ubuntu 10.04 LTS on it for the longest time..
[01:50:47] <XXCoder> young. mines at 8 years old
[01:50:54] <XXCoder> nearing 9 years old
[01:51:18] <LeelooMinai> I week ago I jumped into my basement "server" room with a compressor nozzle in hand - that was pretty fun
[01:51:36] <LeelooMinai> 5 years of dust in PCs
[01:51:41] <XXCoder> fun
[01:51:53] <Connor> Got my Backup server going.. 4 x 4TB Hard Drives! :)
[01:52:00] <XXCoder> I once helped person figure if pc stuffed with 3 years smoke would still work
[01:52:14] <XXCoder> guys smoking gives your pcs cancer too
[01:52:27] <XXCoder> sticky conductive tar cancer
[01:52:57] <Connor> When I was a PC tech back in 95, I charged extra $$ if I had to work on a smokers PC.. Gave me headaches..
[01:53:34] <LeelooMinai> Imagine the lungs of those people
[01:53:43] <XXCoder> no shit lee
[01:53:51] <Connor> okay, so RAID 6 on the backup server's array.. giving me 7.3TB after being formated.
[01:54:14] <XXCoder> heh my pc formerly had raid 5. then 2 drives died
[01:54:29] <Connor> I decided to use xfs, ext3 took up too much disk space.. ext4 not supported on this kernel..
[01:54:41] <Connor> I'm running a Distro Called Openfiler.
[01:55:03] <Connor> The OS is running on a 2GB IDE DOM
[01:55:14] <Connor> Nice little setup.
[01:57:45] <Connor> Ballscrews ordered, Bearings and shims ordered, hardware ordered, 5i25 + 7i76 ordered
[01:58:31] -!- ries has quit [Quit: ries]
[01:58:52] <jdh> made your z ballnut holder yet?
[01:59:00] <Connor> No.
[01:59:13] <jdh> make two :)
[01:59:14] <Connor> Don't have any alumn thick enough for it.
[01:59:35] <XXCoder> get kiln make your own
[01:59:45] <XXCoder> probably cant get one large enough
[01:59:46] <jdh> I saw a 2-part design that looked better
[02:00:05] <jdh> more like the original one where the horizontal part was just a spacer
[02:00:21] <Connor> Went off script from Hoss's plans too..
[02:00:27] <Connor> for the Y ballscrew
[02:00:43] -!- rythmnbls has quit [Quit: Leaving]
[02:01:54] <Connor> Going to bore a hole in the base large enough for the double nut to base into.. so that it'll run into the mountt.. giving another 1/2" or so..
[02:08:11] <roycroft> so my ball screws arrived
[02:08:23] <roycroft> the double support bearings on the motor end are really tight
[02:08:30] <roycroft> are those bearings generally an interference fit?
[02:08:59] <Connor> They can be tight..
[02:09:05] <Connor> you have a lathe?
[02:09:11] <roycroft> yes
[02:09:17] <roycroft> but i also have a freezer and a stove
[02:09:39] <Connor> wrap the screw in beer can and chuck it up and take a emery cloth to it.. LIGHTLY.
[02:09:52] <roycroft> i can do that
[02:10:31] <Connor> just indicate it first.. to make sure you have no run out..
[02:10:33] <roycroft> it probably only needs a couple tenths to fit without trouble
[02:10:37] <roycroft> yes
[02:11:06] <roycroft> supporting a 1150mm long screw in my little lathe might be problematic though
[02:11:14] <roycroft> i can run it slow
[02:11:37] <Connor> yea.. that could be..
[02:11:46] <roycroft> actually, i can put the tail bearing on and bolt that down to a block of wood that i can elevate to the proper height
[02:11:50] <Connor> third party hold it with leather glove ?
[02:12:15] <roycroft> but sticking the screw in the freezer for a while might do the trick with no turning
[02:12:20] <roycroft> i'll try that first
[02:12:38] <Connor> that'll make it really hard to remove the bearing if you ever need to.
[02:13:00] <roycroft> mayhap
[02:13:09] <roycroft> although it really is very close to fitting now
[02:13:15] <roycroft> a puller might do the trick without too much trouble
[02:13:44] <roycroft> the nuts all turn freely, with no discernable play when turning them by hand
[02:13:56] <roycroft> the turning freely part is what is important
[02:13:59] <Connor> you go single, or double nut ?
[02:14:00] -!- mozmck has quit [Read error: Connection reset by peer]
[02:14:07] <roycroft> single
[02:14:14] <roycroft> i'll see if i need double nuts
[02:14:17] <roycroft> if so i'll buy another set
[02:14:25] <Connor> This for lathe or mill?
[02:14:27] <roycroft> router
[02:14:33] <Connor> I did double nuts on mine..
[02:14:34] -!- mozmck [mozmck!~moses@] has joined #linuxcnc
[02:14:37] <roycroft> and i only hope to hold 0.005"
[02:14:49] <Connor> wood router ?
[02:14:52] <roycroft> it's not a high precision machine
[02:14:55] <roycroft> wood and metal engraving
[02:15:09] <roycroft> and possibly some light non-ferrous metal milling
[02:15:10] <Connor> you'll be fine.. You should be able to do .002"
[02:15:12] <roycroft> but very light on that
[02:15:28] <Connor> you get the bearing blocks ?
[02:15:31] <roycroft> yes
[02:15:35] <roycroft> that's what are a tight fit
[02:15:43] <roycroft> i ordered them with the screws from the same vendor
[02:16:13] <Connor> I had issues with those.. you may need shims.. the pockets were slightly too deep on mine.. and couldn't get any preload.
[02:16:18] <Connor> caused backlash.
[02:16:35] <roycroft> they come with sleeves that protrude slightly
[02:16:48] <roycroft> sleeve -> bearing -> spacer -> bearing -> sleeve
[02:16:51] <Connor> yea.. but.. the bearings could still slide back and forth in the pockets.
[02:17:32] <Connor> picture ?
[02:17:32] <roycroft> there's a nut to tighten the bearing block on the motor end
[02:17:44] <roycroft> one moment
[02:18:08] -!- Thetawaves [Thetawaves!~Thetawave@186-51-178-69.gci.net] has joined #linuxcnc
[02:18:58] <jdh> I'd rather them slip fit than have to heat/freeze. You might want to remove them while test fitting
[02:19:35] <Connor> Mine went sleeve -> bearing -> bearing -> sleeve
[02:19:52] <roycroft> i'm still looking for the drawings i have
[02:19:59] <roycroft> there may not be a spacer between the bearings
[02:20:00] <Connor> and I had to have someone make me slightly longer sleeve as the nut rubbed against the seal
[02:20:04] <roycroft> i think there is but i'm not sure
[02:20:18] <roycroft> the nut has a ridge on one side
[02:20:28] <roycroft> so the ridge can press against the sleeve before the nut hits the block
[02:20:43] <roycroft> i can't find my drawings
[02:20:49] <roycroft> i should go take pictures - that would be faster

[02:32:32] <roycroft> http://www.roycroft.us/BallScrews/Bearing_Block.jpeg
[02:32:42] <roycroft> sorry - i didn't bother rotating those
[02:32:47] <roycroft> quick upload and all that
[02:32:50] <roycroft> you can see what i have though
[02:33:20] <Connor_iPad> Yup. Same as I had. You may need a shim to adjust preload.
[02:33:22] <roycroft> not the highest quality bearings ever made
[02:33:44] <Connor_iPad> If the pocket is too deep.
[02:33:49] <roycroft> i don't think i shall, but i'll definitely check for that
[02:33:59] <jdh> those nuts have a built in shim
[02:34:09] <roycroft> yes, that's why i didn't think i would need one
[02:34:11] <Connor_iPad> And be sure to put the bearings back to back.
[02:35:00] <Connor_iPad> But the shim is on the inside race. Which won't do anything
[02:35:04] <roycroft> are those bearings good enough for my application, or would i be better off replacing them with higher end ones right away?
[02:35:15] <Connor_iPad> They're fine.
[02:35:40] <roycroft> well once i get one installed i can check for end play quite easily
[02:35:47] <roycroft> a bearing block that is
[02:35:59] <roycroft> so i'll know if i need a shim or not
[02:37:17] -!- DaViruz has quit [Ping timeout: 272 seconds]
[02:37:40] <roycroft> the tail bearing floats longitudinally, but that should be fine
[02:38:05] <roycroft> if it's secure at the head end that is all that matters
[02:39:05] <roycroft> so i'll touch the shafts with some emory cloth to get a slip fit
[02:39:15] <roycroft> i'll start with the 350mm screw
[02:39:30] <roycroft> i haven't removed a ball nut yet
[02:39:38] -!- revo14 [revo14!~revo14@] has joined #linuxcnc
[02:39:44] <roycroft> i probably don't need to for turning the shafts, if i'm careful and go slowly
[02:39:45] <Connor_iPad> Don't unless you have too
[02:39:58] <roycroft> they don't seem to be at all crunchy
[02:40:07] <roycroft> all three of them move very smoothly
[02:40:43] <roycroft> if i need to add a second set that can be my mandatory playing around with ball nuts exercise
[02:41:40] <roycroft> my plan is to get the screws mounted on the bearing blocks, with zero end play
[02:41:53] <roycroft> mount the blocks securely, then measure backlash on the nuts
[02:42:05] <roycroft> that's when i'll decide whether to get a second set or not
[02:42:06] -!- erve has quit [Ping timeout: 272 seconds]
[02:42:26] <roycroft> it looks like the nuts are about $20 each for those screws
[02:42:35] <roycroft> so probably $100 including shipping
[02:43:15] <roycroft> i'd rather put that $100 towards a nice spindle if the single nuts are not too bad

[05:38:14] <tjtr33> i just faked one using loadusr -W hal_input -KRAL Dual
[05:38:54] <tjtr33> then setp input.0.abs-y-scale -51 then setp input.0.abs-y-offset 127.5
[05:39:03] <tjtr33> that gets me +/- 2.5 float
[05:39:11] <tjtr33> then i input that to a sum 2
[05:39:23] <tjtr33> with 2.5 offset to get 0 to 5 float output
[05:39:59] <tjtr33> this is useful for ancient 00-5v analog input velocity command drives (or other 0-5v analog devices )
[05:42:05] <tjtr33> its not really analog, its chinky with 'steps' of 5v/255 size, but analagous enuf for me
[05:42:12] <tjtr33> chunky

[15:11:26] <varesa> Any idea what this thing strapped onto the cylinder is? http://imgur.com/a/HWrO6
[15:11:53] steve_stallings is now known as steves_logging
[15:13:37] <zeeshan|2> varesa
[15:13:41] <zeeshan|2> looks like some sort of solenolid
[15:13:43] <zeeshan|2> either pressure
[15:13:57] <zeeshan|2> or a capacitive / inductive proximity sensor
[15:13:58] <pcw_home_> yeah a solenoid valve
[15:14:41] <pcw_home_> right could be a pressure/flow switch
[15:14:53] <varesa> I though it was a valve first but then I was no actual connection to the cylinder and there is a valve at the back
[15:15:08] <zeeshan|2> then its more than likely a proximity switch
[15:15:09] <pcw_home_> maybe a pressure switch
[15:15:15] <varesa> So I'm guessing some kind of sensor
[15:15:20] <zeeshan|2> is there fluid in that cylinder?
[15:15:26] <zeeshan|2> or supposed to be
[15:16:02] -!- nofxx has quit [Ping timeout: 245 seconds]
[15:16:27] <varesa> I think that's a pneumatic cylinder
[15:16:39] -!- dan2k3k4 has quit [Ping timeout: 255 seconds]
[15:17:01] <pcw_home_> so maybe a single acting cylinder with a end of travel switch
[15:19:46] <varesa> it could be that
[15:20:34] <pcw_home_> so probably part of the tool changer control handshaking

[15:22:22] <SpeedEvil> Loaded on a good thick pallet to spread the load - sure

[15:30:13] <archivist> and you cannot get the load CG in front of the rear axle easily
[15:30:46] <archivist> flatbed loading from the side could be easier
[15:31:14] <ssi> pallet jack
[15:32:04] <archivist> can the floor take point loads of the pallet truck wheels
[15:32:08] <ssi> and actually if you can find a truck rental with a 5k liftgate, you can move the whole thing with just a pallet jack
[15:32:45] <ssi> dunno about that truck specifically, but a box truck with a liftgate which'll hold the machine will handle the pallet jack
[15:33:28] <ssi> or else do it like this :)

[15:36:43] <ssi> lol
[15:38:16] <archivist> he got me being the "flashing lights in the rear" for that wide load
[15:41:54] <PetefromTn_> Damn this programming is kicking my ass today LOL
[15:42:36] -!- micges-dev has quit [Quit: Wychodzi]
[15:44:50] <ssi> why's that
[15:45:45] <PetefromTn_> well I gotta program a woodruff keyseat cutter to machine a horizontal slot along the perimeter of a real funky shaped part.
[15:46:02] <PetefromTn_> It only goes around it about 3/4 of the way and it is a very odd shape.
[15:46:29] <PetefromTn_> So I machined a clearance pocket for the woodruff cutter to plunge into around the edge with some room to spare.
[15:47:17] -!- micges has quit [Client Quit]
[15:47:18] <PetefromTn_> Now I gotta program this keyseat cutter and when I try to program for multiple passes which is what it is going to take the lead in and out are not wide enough to clear the ledge that the cutter is forming when it makes the slot.
[15:47:51] <PetefromTn_> The entry and exit is in a radiused corner so it is up against that which is what makes it complicated.
[15:47:55] <ssi> I see
[15:48:02] <ssi> are you doing this with cam, or by hand?
[15:48:10] <PetefromTn_> is that a serious question?
[15:48:42] asheppard is now known as sheppard
[15:48:46] <PetefromTn_> no man this is a very funky contour I would not know where to begin to program it by hand.
[15:49:11] <PetefromTn_> I think I have got it now but it took a good while playing with settings and whatnot to get it there.
[15:49:20] <PetefromTn_> Have not actually machined it yet but working on it.
[15:49:58] <ssi> :P
[15:50:03] <PetefromTn_> its like if this were an open contour out in space somewhere this would be a breeze.
[15:50:29] <PetefromTn_> but with the shoulders and radiuses around the entry and exit point it gets real funky and the Cam software does not know what to do with it.
[15:50:49] <PetefromTn_> Of course it would help if I was more experienced
[15:51:18] <PetefromTn_> Oh well it is what it is. Once I get this programmed to work it should work the same way on the other four parts just with a slighlty different shape.
[15:51:31] <PetefromTn_> I gotta get this done here and soon...

[17:19:26] <cradek> mine works when I plug it in to the usb and do nothing special at all
[17:19:32] <cradek> so you'll have to be much more specific
[17:21:08] <cradek> I've made a serial one work in the past, but it was much much harder
[17:21:48] <Roguish> ok. i'll try it again. it is a Monoprice 15", usb. I would like to try Touchy.
[17:22:05] <Roguish> pretty much a knock off of an Elo.
[17:22:25] <Roguish> maybe Elo inside.

[17:24:53] <Roguish> did a sudo lsusb, get command not found
[17:25:13] <Roguish> do i need to be in a certain directory?
[17:25:28] <CaptHindsight> I was using multitouch on precise. It worked even better on Trusty so multitouch has more to do with the desktop tweaks than anything
[17:25:49] <cradek> Roguish: here's how you fish: apt-cache search lsusb
[17:25:57] <CaptHindsight> I'd like to get it working well on Wheezy
[17:26:24] <asah> pcw: in an 8i20 is the “current” commanded value the actual current flowing through the wires in all conditions?
[17:26:31] <cradek> multitouch doesn't matter for touchy, and I think an elo touchscreen won't do it anyway

[17:28:40] <asah> the other lists 17.1 amps peak.
[17:29:25] <asah> I have the nvmaxcurrent set to 1710 for 17.1 amps.
[17:29:33] <asah> for that axis.
[17:29:48] <asah> but realizing that value does not hold for the others.
[17:29:58] <pcw_home_> yeah its hard to tell what they mean but assuming they mean total (heating) current then that is correct

[17:31:11] <asah> sorry, continuous
[17:31:29] <asah> then I had better be averaging that.
[17:31:58] <asah> anyway, thats a small digression, Ill watch that during testing with all axes moving.
[17:32:20] <asah> how would you rate a motor you do’nt have peak current rating for?
[17:32:33] <asah> 2-3x stall?
[17:33:41] <pcw_home_> Yeah maybe 2-4x depends on magnet types

[19:16:45] <MrHindsight> nofxx: how about optical or inductive?
[19:17:19] <nofxx> MrHindsight, yeah.. the ceramic I mean inductive* does it touch? Optical looks the nicer ... any recommendation?
[19:17:49] <Loetmichel> nofxx: if metal swarf is in reach: use mechanical swithces
[19:17:55] <Loetmichel> MUCH less prone to failure

[19:28:30] <nofxx> optical is nice cuz got a lot from old printers
[19:29:50] <MrHindsight> printers are almost always in a clean environment
[19:31:18] <MrHindsight> LED + photodiode and something opaque to block the light, like dirt, swarf, coolant etc

[21:33:04] <zeeshan> nope
[21:33:04] <jdh> afaik, everyone is better than ups
[21:33:09] <zeeshan> same brokerage bull crap
[21:33:34] <jdh> how much of the money goes to ups vs. .ca?

[21:34:04] <Loetmichel> ... the ones that are made to withstand 30++g

[21:34:14] <LeelooMinai> Military printers... lol
[21:34:29] <zeeshan> http://www.ups.com/content/ca/en/shipping/cost/zones/customs_clearance.html
[21:34:38] <zeeshan> whatever that $ value is
[21:34:42] <zeeshan> multiply it by 1.13
[21:34:51] <zeeshan> thats the extra bullshit you pay
[21:34:57] <zeeshan> on top of taxes
[21:35:23] <Loetmichel> LeelooMinai: the company i work for makes military IT tech
[21:35:46] <zeeshan> so 200$ pkg = 29$ * 1.13 = 32.77 (29 goes to ups, gov takes the extr aamount) and then you pay 200*0.13 = $26 to the government
[21:35:55] <LeelooMinai> Bizzary world of milspec where one smd capacitor can cost $20:)
[21:35:56] <zeeshan> so in total you'll pay 32.77+26 out of your pocket
[21:36:19] <Loetmichel> ups managed to destroy 2 of these: http://www.cyrom.org/palbum/main.php?g2_itemId=3209

[21:40:09] <LeelooMinai> Maybe you need a new spec - UPS-specced printers:)
[21:40:17] <Loetmichel> seems that way
[21:40:45] <LeelooMinai> On the other hand... who the hell prints on a dot matrix inside a tank? :)
[21:41:00] <Loetmichel> we were joking that we copuld have used ups instead of the expensivce Gforce testing at frauenhoifer institute ;-)
[21:41:20] <Loetmichel> no idea
[21:41:36] <Loetmichel> i just build the things, i dont know how they are used ;-)
[21:41:39] <LeelooMinai> That's just bizzare... I would think that in 2014 they have better tech
[21:41:50] <Loetmichel> burt dot matris is nearly the only useable printing there
[21:41:53] <CaptHindsight> interesting, and I never use Fedex since they either lose it or break it
[21:42:19] <Loetmichel> laser would throw toner all around, ink cant cope tith -20 to +50°c...
[21:42:31] <LeelooMinai> Yes, I guess lazers are too fragile
[21:42:47] <LeelooMinai> But thermal printers could do maybe?
[21:43:09] <DaViruz> thermal printouts are pretty fragile though
[21:43:10] <Loetmichel> yes, the wax printers would be a possibility

[21:43:41] <LeelooMinai> A, printouts
[21:43:45] <Loetmichel> and the humidity because they use single sheet paper instead of endless...

[23:27:44] -!- maximilian_h has quit [Ping timeout: 250 seconds]
[23:28:01] <PetefromTn_> The Diameter column contains a real number. This number is used only if cutter compensation is turned on using this tool. If the programmed path during compensation is the edge of the material being cut, this should be a positive real number representing the measured diameter of the tool. If the programmed path during compensation is the path of a tool whose diameter is nominal, this should be a small number (positive or nega
[23:28:14] <PetefromTn_> I don't understand this statement in the linuxCNC files
[23:28:50] <PetefromTn_> what the hell does that fourth sentence mean?
[23:29:39] <PetefromTn_> cpresser I typically have been doing it the way you suggest as well but I am trying to work like a professional shop here and every shop I have worked in uses Cutter Comp. Mostly to be able to creep up on dimensions without having to repost code
[23:30:52] -!- asdfasd has quit [Ping timeout: 240 seconds]
[23:31:41] <Tom_itx> you sometimes _can_ get into trouble using comp
[23:31:52] <PetefromTn_> of the tool and the nominal diameter. If cutter compensation is not used with a tool, it does not matter what number is in this column. this is the last part of that paragraph.
[23:32:03] <Tom_itx> if a radius is smaller than the cutter+comp it will error
[23:32:07] <PetefromTn_> tell me about it. Just screwed up a part with it damnit...
[23:32:29] <Tom_itx> and then will sometimes go in a large arc
[23:32:49] <PetefromTn_> I did use it on a quarter inch round pocket with an 1/8 inch tool and it worked great..
[23:32:59] <Tom_itx> that would
[23:33:10] <PetefromTn_> ?
[23:33:33] <Tom_itx> the tool is small enough comp shouldn't cause a problem there

[23:33:49] <Tom_itx> heh

[23:34:39] <cpresser_> "If the programmed path during compensation is the path of a tool whose diameter is nominal, this should be a small number (positive or negative, but near zero) representing only the difference between the measured diameter of the tool and the nominal diameter." meaning: you can use cutter-comp to compensate the real vs. nominal tool-diameter.
[23:34:42] <PetefromTn_> Man I am so pissed off right now...
[23:35:10] <cpresser_> if you program the exact path with your cam; but your tool is .1 smaller, you can write that .1 into the tool table
[23:35:21] <cpresser_> and use comp to get an accurate part
[23:35:26] <PetefromTn_> yeah that is what I figured it was for.. I input .3755 for my 3/8 inch endmill and it screwed it up..
[23:36:06] <cpresser_> so far, i think .3755 is a good idea for that usecase
[23:36:15] <cpresser_> what exactly went wrong?
[23:36:18] <PetefromTn_> so is it possible that my cam is posting actual toolpath and I should have just put how much I wanted it to stay off the part
[23:36:32] <PetefromTn_> it cut like half the freaking diameter of the cutter into the edge of the part.
[23:36:55] <cpresser_> most likely your cam will generate the actual toolpath. my cam puts a G40 into the first line to indicate this as well
[23:37:50] <cpresser_> ~actual toolpath = centerline-of-tool path. sorry, english is not my native language. i am missing some of the words :)

[23:38:40] <cpresser_> in your case, G41 + tool-diameter=0.37 means that linuxcnc will offset the programmed path by 0.37
[23:38:53] <PetefromTn_> my post has the G40 in the preamble but when it calls the tool it sets up G43 H and G42 D numbers does the preamble negate that?
[23:39:43] <cpresser_> yes. G40 and G42/43 are the same modal group
[23:39:51] <cpresser_> they cancel each other out AFAIK
[23:40:06] <PetefromTn_> if that is the case then how come it worked when I programmed the eight inch cutter?
[23:40:15] <PetefromTn_> eighth
[23:41:24] <PetefromTn_> so if I program the tool table for like -.005 it will cut off the path that much outside?
[23:41:43] <cpresser_> no clue.http://www.linuxcnc.org/docs/2.4/html/gcode_overview.html#sec:Modal-Groups
[23:41:49] <PetefromTn_> The part is toast already dammit so I guess I will just try it and see what happens.
[23:42:10] <cpresser_> outside.. depends if G41/G42 is used :)
[23:42:20] <PetefromTn_> Honestly if it was that way I would probably prefer it so I can just input the difference I want and not have to whip out the calculator all the time LOL

[23:43:01] <cpresser_> there is also G41 and G41.1, where the first uses the tool-table value, and G41.1 has a D-parameter

[23:44:22] <PetefromTn_> I'm gonna try it and see what happens
[23:44:39] <PetefromTn_> Well trying to use CamBam here but not sure if I am doing it right or not....
[23:44:50] <zeeshan> PetefromTn_: it also depends on whether its an external feature youre conturing
[23:44:52] <zeeshan> or internal
[23:45:02] <PetefromTn_> Like I said have never used Comp on my personal machines so far..
[23:45:13] <PetefromTn_> its external.
[23:45:44] <zeeshan> so youre doing a g41?
[23:45:51] <zeeshan> or a g42
[23:46:20] <PetefromTn_> it posted a g42 D3
[23:46:39] <zeeshan> weird
[23:46:51] <cpresser_> and you have tool 3 loaded?
[23:46:59] <PetefromTn_> sure
[23:47:03] <zeeshan> i would have really thought it'd be g41..
[23:47:11] <zeeshan> because you want your tool to shift to the left of your part
[23:47:13] <zeeshan> not to the right
[23:47:20] <zeeshan> to the right would make it plunge more into the part
[23:47:24] <PetefromTn_> it looks good in the cam simulation.
[23:47:35] <zeeshan> yea, but your cam simulation doesnt understand how linuxcnc works
[23:47:39] <cpresser_> check it in the preview-window of axis
[23:47:55] <PetefromTn_> and if it did go to the wrong side it would be WAY inside not halfway inside..
[23:47:56] <zeeshan> i spent 3 days writing a custom mastercam post processor to work with the lathe
[23:48:02] <zeeshan> :(
[23:48:14] <PetefromTn_> I WISH I could afford mastercam.
[23:48:20] <zeeshan> no
[23:48:26] <zeeshan> im saying sometimes your cam will simulate correct
[23:48:31] <zeeshan> but your g-code output is wrong
[23:48:42] <zeeshan> know what i mean?
[23:48:47] <PetefromTn_> no not really.
[23:49:04] <zeeshan> like for example, when setting up constant surface speed mode..
[23:49:14] <zeeshan> mastercam was outputting some weird g-code
[23:49:18] <zeeshan> and it was completely unrecognizable
[23:49:23] <zeeshan> when i imported in linuxcnc
[23:49:29] <zeeshan> even the way it was doing arcs was wrong
[23:49:52] <zeeshan> if you look at mastercam's post processor options for mill for example
[23:50:13] <PetefromTn_> Can't don't have it..
[23:50:19] <zeeshan> they've got cincinnati arrow, haas vl7 or some other stuff
[23:50:28] <zeeshan> so theres like 25 different machines you can select
[23:50:38] <zeeshan> each will output g-code for the same cam simulation
[23:51:13] <PetefromTn_> BRB
[23:51:18] <PetefromTn_> Gonna try somethin here.
[23:51:25] <zeeshan> i would just do a simple 3 line code
[23:51:33] <zeeshan> w/ cutter compensation and see if it does wha tyoure asking it
[23:52:05] <zeeshan> i meant to say emag vl7 not haas vl7 btw!
