[00:19:40] <andypugh> PetefromTn_: You don't even need to adjust anything really. The centre line of the spindle is the pixel that doesn't move when you wiggle the spindle.

[00:20:36] <XXCoder1> set it to one rpm and let program figure align nonrotating point on 0,0
[00:20:45] <XXCoder1> issue is wire lol
[00:20:56] <JT-Shop> wireless
[00:21:25] <XXCoder1> there ya go heh
[00:22:38] <andypugh> i just had to add 50mm to my Z travel limits.Which involved investigating if I was going to let the balls fall out the screw...
[00:23:18] <andypugh> I need to use the horizontal spindle to machine the edge of the work, as it is too big for the machine otherwise: https://picasaweb.google.com/lh/photo/uoy2UegtJpcl6BD88u_lFdMTjNZETYmyPJy0liipFm0?feat=directlink
[00:25:27] <Tom_itx> not enough travel in X to do it?
[00:25:38] <Tom_itx> err nevermind
[00:25:55] <andypugh> No, not enough daylight under the vertical head
[00:26:33] <andypugh> This is the forst proper CNC job I have done on the machine, I think. Using CAM and suchlike: https://picasaweb.google.com/lh/photo/CSu6UI0YPPadVzIdnFPyFtMTjNZETYmyPJy0liipFm0?feat=directlink
[00:26:58] <XXCoder1> awesome
[00:27:07] <Tom_itx> i was just looking at that one
[00:27:10] <andypugh> I am wondering why the vertical spindle gets so hot, though.
[00:27:26] <andypugh> I wonder if the bearings are wrongly adjusted?
[00:27:41] <Tom_itx> shaft rubbing on something?
[00:27:53] <Tom_itx> or bearings..
[00:28:17] <Tom_itx> did you use cambam for that?
[00:28:18] -!- rob_h has quit [Ping timeout: 240 seconds]
[00:29:12] <andypugh> Yes.
[00:29:16] <Tom_itx> what was your impression of it's 3d capabilities other than the waterline issue?
[00:29:16] <PetefromTn_> Hard to see the parts from the pics..
[00:29:23] <andypugh> It works pretty well when you figure it out.
[00:29:48] <andypugh> The parts are buried in pockets in a fixture (hot-melt glue)
[00:30:10] <Tom_itx> did you mill the backside flat?
[00:30:21] <Tom_itx> or does it have the bend shown in the drawings
[00:30:40] <andypugh> Yes. Though actually I could have put the kink in, with this work plan.
[00:30:44] <XXCoder1> I need to buy cambam so I can do tutorials without running into limits
[00:30:54] -!- Tugge_ [Tugge_!~tugge@a91-153-45-7.elisa-laajakaista.fi] has joined #linuxcnc
[00:31:21] <Tom_itx> i downloaded it but haven't used it except to look at a post
[00:31:34] <PetefromTn_> I am liking CamBam so far. It is the best of the low cost bunch that I have tried but it is not without quirks.
[00:31:43] -!- MacGalempsy [MacGalempsy!~quassel@ip68-12-21-167.ok.ok.cox.net] has joined #linuxcnc
[00:31:53] <Tom_itx> what others did you look at?
[00:32:01] -!- lyzidiam_ has quit [Remote host closed the connection]
[00:32:44] <PetefromTn_> So far I have posted probably a little over a dozen programs to the machine and so far everything worked exactly as it was supposed to.
[00:33:27] <andypugh> PetefromTn_: I had to modify the default EMC post to add the G43 to a toolchange.
[00:33:48] <Tom_itx> i think we did that as well but i can't honestly rememeber
[00:33:51] <PetefromTn_> Oh man we tweaked the post quite a bit...
[00:34:14] <andypugh> And I am going to get rid of the move-to-clear height before a toolchange too, because that can be bad if you have actually already insterted the new (longer) lool.
[00:34:15] <PetefromTn_> It is not perfect but works great for me so far.
[00:34:39] -!- Tugge has quit [Ping timeout: 255 seconds]
[00:35:02] <PetefromTn_> Huh I don't understand that?
[00:35:38] -!- uwe_ has quit [Ping timeout: 240 seconds]
[00:35:45] <PetefromTn_> YOu mean the safe Z height?
[00:35:48] <andypugh> The limiting speed in grease is 4400 and in oil is 5800. SO I don't think that they should be getting toasty-hot at 1000rpm?
[00:36:01] <Tom_itx> wouldn't think so
[00:36:14] <andypugh> Yes, CamBam puts in a "move to clear height" before the tool change.
[00:36:38] <Tom_itx> clear should clear any obstructions...
[00:36:39] <PetefromTn_> how is that a problem I still have that in there as well
[00:37:03] <Tom_itx> that is one reason i set my z well above any work or fixtures
[00:37:05] <PetefromTn_> Even the Haas Machines where I am working temporarily do that..
[00:37:11] -!- lyzidiamond has quit [Ping timeout: 252 seconds]
[00:37:35] <andypugh> So, if you previously had a short tool in, but have (manually) inserted a longer tool, but haven't done the G43, because you can see that a toolchange is almost the first thing in the program, then it can crash the tool.
[00:37:59] <Tom_itx> i actually move my model in the cad down 3" or so then post, using a 3" 123 block to set the tools from then
[00:38:05] -!- GuShH_ [GuShH_!GuShH_Lap@unaffiliated/gushh] has joined #linuxcnc
[00:38:33] <andypugh> Well, my machine is configured to quill-up for tool change. So rather often you get a qill-down to clear-height then a quill-up for tool change (in that order)
[00:38:40] <Tom_itx> you shouldn't be changing the tools until the program calls for it :)
[00:38:50] <PetefromTn_> Dunno why you would do that, all my tools use TLO's and I set them all before running anything.
[00:39:05] <Tom_itx> andypugh yeah once in a while my post will output such a move
[00:39:08] -!- thomaslindstr_m has quit [Quit: Leaving...]
[00:39:16] <Tom_itx> i haven't really been able to pinpoint where it's being inserted yet
[00:39:19] <andypugh> I have manual tool-change, but measured tool heights.
[00:39:39] <PetefromTn_> me too...so far anyways.
[00:39:42] <Tom_itx> i set mine up in the tool table and leave them in the holders
[00:40:25] <PetefromTn_> I did run into a problem with a CamBam Quirk yesterday tho.
[00:40:41] <PetefromTn_> When I made that part I showed pics of yesterday.
[00:40:52] <Tom_itx> andypugh, does the whole vertical head come off yours to become a horizontal cutter?
[00:40:59] <Tom_itx> driven off the same shaft?
[00:41:02] <andypugh> Another quirk (the same cause) was the set of canned-cycle holes I just drilled. So, it went to clear-height, then did a tool change (quill-up) then did the G98, so there was a full-travel rapid between each hole :-)
[00:41:02] <GuShH_> Loetmichel: Does Mach3 have any issues whatsoever with AMD processors?
[00:41:46] -!- uwe_ [uwe_!~uwe_@dslb-088-064-212-101.pools.arcor-ip.net] has joined #linuxcnc
[00:41:50] <PetefromTn_> I did the outside profile using a .dxf drawing I made and in CamBam used the Join feature to make it a polyline.
[00:41:51] <andypugh> Tom_itx: Yes, as can be seen in that photo I posted a few minutes ago, with the vertical head dangling from the roof, and the toolholder in the horizontal.
[00:42:07] <Tom_itx> that's why i asked
[00:42:16] <PetefromTn_> I then created MOP's off that like outside profiling etc..
[00:42:32] <PetefromTn_> Then I wanted to only Champfer certain parts of the outside profile.
[00:42:34] <andypugh> Ah, yes. When dragging polyline points in the XYplane, why do they move randomly in the Z plane?
[00:42:56] <PetefromTn_> So I exploded the polyline and created MOP's for that.
[00:43:30] <PetefromTn_> When i posted the enitre code the previous ops that used the unexploded polyline were broken and did not post despite being enabled when posted.
[00:43:31] <andypugh> PetefromTn_: Might have been easier to draw a boundary shape.
[00:44:21] <PetefromTn_> I asked about this on their forum and Lloyd suggested in the future that I copy and paste the polyline over top of the existing one somehow and explode that to do the individual MOP's...
[00:45:40] <Tom_itx> can you change a drawing line to become a tool path?
[00:46:00] <PetefromTn_> sure or you can just do an engrave no offset mill.
[00:46:09] <PetefromTn_> I actually did that on this part I just made..
[00:46:30] -!- Servos4ever has quit [Quit: ChatZilla [SeaMonkey 2.24/20140203230751]]
[00:46:54] <andypugh> I wanted to corner-round a shape with changeing Z, and couldn't figure out how to do it. (I habd-coded in the end)
[00:47:24] <PetefromTn_> http://imagebin.org/301463
[00:47:50] <PetefromTn_> I actually drew two arc
[00:47:57] <XXCoder1> pete did your cnc do inside spots?
[00:48:04] <XXCoder1> if so, thats pretty smooth indeed.
[00:48:24] <XXCoder1> and how the heck do you do edge lips on pockets? I couldnt think of way.
[00:48:56] <PetefromTn_> lines to create a geometry to do a peel milling operation to help rough out the outside of the arcs before I did an outside profile..
[00:49:03] <andypugh> In the skip at eork today I found a 150-175mm micrometer and two 3-point bore comparators. Which are no longer in the skip.
[00:49:19] <PetefromTn_> Yeah the entire part was made on the Cincinatti Arrow 500 VMC with LinuxCNC...
[00:49:25] <XXCoder1> cool
[00:49:30] <PetefromTn_> Do you mean the champfer?
[00:49:38] <XXCoder1> yeah couldnt think of proper word
[00:49:48] <XXCoder1> that 45 angle before start of hole
[00:50:10] <PetefromTn_> Yeah that is a simple inside profile operation with a vee cutter and some offset and depth calculations to get the right champfer.
[00:51:02] <XXCoder1> cool. I guess its something I have to play with
[00:51:16] <humble_sea_bass> ooh. the unclampable part done got clamped

[00:52:19] <XXCoder1> well yes and no
[00:52:51] <XXCoder1> thats why I plan to go though tutorials and such to get skills properly gauged and filled in
[00:53:12] <humble_sea_bass> you doing this bass ackwards
[00:53:23] <XXCoder1> not surpised
[00:54:34] <humble_sea_bass> do yourself a solid and grab any old book about technical drawing and/or engineering graphics
[00:54:44] -!- toastyde1th [toastyde1th!~toast@] has joined #linuxcnc
[00:54:59] <XXCoder1> no prob
[00:55:45] <ChuangTzu> hmm
[00:55:49] <andypugh> Well, there is something to be said for machining first, you are less likely to design unmachinable things :-)
[00:55:49] <XXCoder1> I have been playing with inkscape, 3d render software and such on and off across years so cambam I picked up pretty quickly but since it works with something completely new
[00:56:11] <XXCoder1> I guess it will take me a bit
[00:56:35] <andypugh> Depending on what you are trying to make you are likely to find something parametric better than a direct modeller.
[00:56:38] <humble_sea_bass> well put andy, but I think having the syntax to communicate ideas is really important
[00:56:43] <ChuangTzu> i picked up solidworks and learned it in like half a day
[00:56:57] <ChuangTzu> but maybe i should go back and get one of these... books.... as you call them
[00:57:11] <XXCoder1> humble that is where my weak area is. I always forget it too. probably why I never could get a CS job lol

[00:58:00] <CaptHindsight> ChuangTzu: the more difficult aspects of SW is merging different areas and getting all the tools to work right
[00:58:25] <XXCoder1> thanks for link
[00:58:48] <XXCoder1> wow so cheap
[00:58:52] <XXCoder1> its one of best eh
[00:58:55] <andypugh> I picked up Inventor basics in half a day, but I am still learning. And that is after spending 2 years working with it 8 hours a day.
[00:58:58] <humble_sea_bass> they are old as shit
[00:59:02] <humble_sea_bass> but the information is good
[00:59:09] <CaptHindsight> don't they teach drafting in high school anymore?
[00:59:13] <XXCoder1> yeah I have C book thats almost as old as C language lol
[00:59:23] <humble_sea_bass> Cap, you think schools are made of money??
[00:59:24] <ChuangTzu> yeah, i still learn a lot about solidworks
[00:59:25] <XXCoder1> capt I wouldnt know, I went to deaf schools
[00:59:27] KreAture is now known as KreAture_Zzz
[00:59:33] <ChuangTzu> and there is still a lot i don't know
[00:59:38] <jdh> my daughter is taking a solidworks class
[00:59:43] <humble_sea_bass> XXCoder1: which one/
[00:59:45] <ChuangTzu> but i can do what i want with it and could from the first half day
[00:59:59] <ChuangTzu> but what i'm saying is, maybe i'd benefit from a book
[01:00:04] <CaptHindsight> humble_sea_bass: more like money pits
[01:00:14] <ChuangTzu> on actual drawing
[01:00:31] <ChuangTzu> i'm a scientist, i've never taken any classes on practical shit :)
[01:00:47] <humble_sea_bass> actual drawing nips a lot of bad habits in the bud
[01:01:00] <XXCoder1> dunno havent even looked at book for years now
[01:01:04] <CaptHindsight> humble_sea_bass: drawing nips?
[01:01:12] <XXCoder1> its amazing reference book for c
[01:01:17] <XXCoder1> 1980s
[01:01:18] <humble_sea_bass> yeah that sounded suboptimal
[01:01:42] <humble_sea_bass> XXCoder1: the new edition is like 150 bux and won't show you much
[01:01:58] <XXCoder1> its because of damned colleges
[01:02:00] <andypugh> I should have tried this earlier tonight. But I had forgotten it exists: http://openscam.org
[01:02:20] <XXCoder1> maybe one word change and your old edition is worthless and new book is $20 higher new than last one
[01:02:23] <humble_sea_bass> open >>>SCAM<<< dot org.
[01:02:38] <Tom_itx> the more you machine the more you learn about fixtures too
[01:02:38] <humble_sea_bass> sorry obama. keep your open out of my scam
[01:02:44] <CaptHindsight> why did they name it open-scam vs open-cam?
[01:03:05] <XXCoder1> lack of domain avil?
[01:03:34] <XXCoder1> read about its issues. some isnt good
[01:03:45] <andypugh> Why did they create expertsexchange and therapistfinder? Sometimes you read what you know it says.
[01:04:15] <andypugh> A new version was just announced on the LinuxCNC - dev list.
[01:04:23] <Tom_itx> anything like openscad?
[01:04:30] <Tom_itx> i'm not very fond of that

[01:06:00] <Tom_itx> my cam has a preview similar to that
[01:06:15] <Tom_itx> i don't use it alot
[01:06:33] <CaptHindsight> http://www.youtube.com/watch?v=fTaKDnSIb4c
[01:06:35] <Tom_itx> i view the cutter paths more than the solid
[01:07:06] <XXCoder1> amazon has a hardcover copy for one penny + shipping.
[01:07:17] <XXCoder1> 1980 edition though. is it worse humble?
[01:08:33] <humble_sea_bass> dude it is fine
[01:09:17] <humble_sea_bass> get the 1936 version if they have it, pencils, ink and straight edges didn't make much progress over the decades
[01:09:38] <XXCoder1> okay will order when get back. dinner heh
[01:09:56] <humble_sea_bass> although I assume the 1980 version will be in that text book size we all know and love with more pictures and nicer paper

[01:28:35] <CaptHindsight> can you use it to notch your bed or table?
[01:28:36] <somenewguy> well lucky for me , with the shape of my head and fixture, generally it will crash into something removable before hitting the precious bed
[01:28:47] <skunkworks> I mean find any unforeseen bugs..
[01:28:47] <somenewguy> well, not on purpose lol
[01:28:56] <CaptHindsight> that's what Mach3 is for!
[01:29:17] <somenewguy> but in all seriousness, I am actaully ready to let ppl try out the few working routines, if they are interested in giving feedback
[01:29:31] <CaptHindsight> add counts even when your encoders aren't moving
[01:29:39] <CaptHindsight> it's a feature, not a bug
[01:29:45] <somenewguy> I run steppers, but that is why I left mach3
[01:29:59] <somenewguy> the code is so effecient in mach3, someteims the motors move even BEFORE you send a command

[01:39:00] <somenewguy> I'm glad I nicked my vice the second day I had the mill
[01:39:04] <somenewguy> makes it easier to live with
[01:39:19] <somenewguy> PO hit the bed a few times, and for several inches impressivly
[01:39:42] <somenewguy> how do you mill a rectangle out of your bed, seriously?
[01:40:01] <humble_sea_bass> they were looking for hidden treasure
[01:40:05] <skunkworks> I think the worse we have so far is an 1/8 in cutter pulled out of the collet and cut a small slot in the angle plate before it broke
[01:40:06] <XXCoder1> lol
[01:40:41] <PetefromTn_Andro> My Cincinnati actually you would have to try hard to hit the bed the head does not come that close so you would need to either drill it or have a longer endmill.

[01:41:19] <skunkworks> I did form some aluminum when the hd started re-directing sectors.. (lost the tool change position because the var file got nuked.)
[01:41:25] <humble_sea_bass> in college this one group drove a drill bit into the bed and broke it off so this thing was in there like excalibur
[01:41:48] <PetefromTn_Andro> I never work directly on the table usually part is in vise or atop some 123 blocks or substrate.
[01:41:48] <somenewguy> I found one of those in my bed....
[01:42:00] <somenewguy> ^seriously
[01:42:07] <CaptHindsight> the other exciting thins about the mach setup is if the hydraulics are on and the e-stop, if you kill/power-off/crash the PC the spindle starts up at the last set speed
[01:42:15] <somenewguy> and make sure you know how high you are off the bed lol
[01:42:15] <XXCoder1> humble couldnt they mill it flush?

[01:43:53] <PetefromTn_Andro> Capt when I first got my VMC for some reason when I powered up the control the vfd had no signal control yet and would ramp up to Max speed immediately. Scared the freaking shit out of me.
[01:44:47] <humble_sea_bass> XXCoder1: it got pulled out after a few days and basically we just had a hole on the table for the rest of semester I was tehre. I finished my work so I gave no fucks and graduated

[02:01:17] <skunkworks> I would post it.. More people trying it - the better. just say that it is experimental - use at your own risk
[02:01:26] <somenewguy> I am basically adding single function routines as I need them

[03:57:31] <XXCoder1> manual one
[03:57:34] <zeeshan> i could send you pdf

[14:25:15] <miss0r1> I have had a thought! (waiting for applause)... too much vertical movement is bad for the tools in a mill, because the middle of the tool essentially stands still, so my thought is: Do any of you use a ramp when you 'dig into' a pcb? or is that considered overkill?

[14:35:56] -!- maximilian_h has quit [Ping timeout: 252 seconds]
[14:36:13] <cpresser> miss0r: for engraving i use .3mm china engraving tools
[14:36:54] <miss0r> alright. A ball head or a straight head?
[14:37:10] <cpresser> straight. let me search for a picture..
[14:37:37] <miss0r> I am just having issues with the finish of the cobber when I use a straight head.
[14:37:46] <cpresser> miss0r: http://www.gis-tec.com/images/express_photo.jpg
[14:38:35] <miss0r> cpresser, Oh! you happy with the result of that?
[14:39:37] <cpresser> miss0r: it all depends on how flat i can mount the copper-plate onto the bed
[14:40:18] <miss0r> cpresser, Indeed - I build a vacuum table a few days back, with 50 suction holes underneath a 160x100 pcb
[14:41:28] <miss0r> That seems to do the trick. I should try with the cheap chinese tool for milling.

[14:46:59] -!- theorbtwo [theorbtwo!~theorb@] has joined #linuxcnc
[14:48:11] <miss0r> I use an industrial vacuum cleaner. But a regular one will do as well, as long as you make sure it does not overheat due to the lack of airflow. And I am VERY happy with the result
[14:48:28] <miss0r> http://picpaste.com/DSC_0082-JdRK7Imi.JPG
[14:48:35] <miss0r> I seem to have it at an angle, sorry about that
[14:50:09] <miss0r> I made it out of a slab of nylon. I basicly build it, mounted it securely and milled off 0.2mm of the top with a 3mm mill
[14:50:19] <miss0r> to make damn sure it was straight
[14:51:20] <cpresser> that looks nice
[14:51:46] <cpresser> i assume there is some kind of adapter for the 5 hoses to attach to the shop-vac?
[14:52:35] <miss0r> Well, I have just used a standard electrical junction box (100x100x40mm) with soft rubber seals for cables, and I drilled a hole in the lid
[14:52:41] <miss0r> for the vacuum
[14:54:37] <miss0r> my idea with using 5 separate hoses and 5 separate chambers inside the vacuum table, is that I can place a small object on there, as long as I have 70% of the holes in each chamber used blocked. Then it will stick.
[14:55:26] <miss0r> When I place a board on there, and drop it, it makes a serious 'smack'.... My best guess is that I have to use aprox 5kg of force to move it sideways and somewhat more to lift it directly off.
[14:55:57] <miss0r> The way really beats thoes 4 clamps i used to use
[14:59:48] <miss0r> also: the chinese mill i bought had a control box that was a little too chinese for my taste, so i build an upgrade: http://picpaste.com/DSC_0083-y12RXfZP.JPG

[17:02:23] <archivist> schef, it is just a case of reading the pinouts and working out what each one needs, you can use stepconf

[17:11:13] <schef> i tryed that..i read a pdf manual which pin is what and used stepconf but coudnt get it runing
[17:13:06] <schef> in manual it sais that i have to have xyzab axis but in linux i cannot choose b..x axis has two step mottors y a z have one..could that be the case..
[17:13:18] -!- patrickarlt has quit [Ping timeout: 268 seconds]
[17:14:36] <archivist> not sure that stepconf has a gantry where two are slaved, you may need to hand edit the config files
[17:16:24] <schef> can you make an example..i'm new to this..pleas..
[17:16:45] <cpresser> schef: start with the axes which habe only one stepper, thats easier. you only need 2-3 pins for that (step, dir, enable)
[17:17:10] <schef> aha..
[17:17:51] <schef> i didnt hear the sound of the mottors when i started linuxcnc..the motors dont turn on..
[17:18:00] <cpresser> schef: i think stepconf is the easiest way to go
[17:18:06] <schef> like they do in mach3 when i click reset..
[17:18:13] <cpresser> schef: please post a link to the manual
[17:18:45] <schef> http://www.katodo.com/Documentation/10.9031.0007/CNC_TB6560_4-Axis_Stepper_Motor_Controller.pdf
[17:19:56] <cpresser> schef: page5 has the pinout. Pin1 does enable all axes. make sure you configure this pin
[17:20:05] <R2E4_> That looks pretty straight forward.
[17:22:50] -!- patricka_ has quit [Read error: Connection reset by peer]
[17:23:30] <cpresser> linuxcnc has a 'amplifier enable' pin. connect that to pin1 in stepconf

[17:25:29] <schef> i put estop in or out...thats the proble i think

[18:09:20] <IchGuckLive> oh yes there i see the problem
[18:09:35] <IchGuckLive> stop mashine operation
[18:09:56] <IchGuckLive> they tunneled the power and the Db25 cable to a walkway
[18:10:12] <pcw_home> OK a crc error or other noise generated error would not stop the machine
[18:10:25] <IchGuckLive> steel pipe and there are up to 5 plasmas in the shop
[18:10:46] <pcw_home> actually sounds more like a power issue at the 7I76
[18:11:25] <pcw_home> (sound like comms just dropped out entirely rather than having a transient error that you woudl expect with noise)
[18:11:34] <Connor> pcw_home: PeteFromTN was getting those 5i25/7i77 serial error's when ever he clicked the spindle direction on his VFD. (Even before giving it a speed). After he switched to Modbus, it stopped.. we never could figure out what was causing that.

[18:14:31] <pcw_home> (you will se 10s of volts of 1 MHz + signals)
[18:15:11] <pcw_home> ground is just an autotransformer at HF
[18:15:31] <Connor> Okay, so, 7i76E that's a Ethernet version of the 7i76 ? Not supported yet? and, how does that work. Are the commands still off-loaded to a FPGA ?
[18:15:48] KreAture_Zzz is now known as KreAture
[18:16:21] <pcw_home> I have one working here but ist still a bit beta
[18:16:36] <Connor> Saw it on the store. :)
[18:16:57] <Connor> So, does it have a FPGA built in?
[18:17:04] <pcw_home> its really all the same, uses Ethernet in real time

[18:18:06] <Connor> Yea, I was just trying to figure out were the FPGA came into play.. the 5i25 being the FPGA connecting to the 7i7x cards.. since this was Ethernet... were the FPGA was at.
[18:18:07] <Connor> okay.
[18:18:11] <Connor> makes sense.
[18:18:43] <Connor> meant for point-to-point ethernet, no switches/hubs in between ?
[18:18:54] <pcw_home> Yes
[18:19:33] <pcw_home> (and host mac is dedicated to 7I76E/7I77E/7I80)
[18:19:59] <Connor> I probably should look at getting a 5i25 + 7i76 combo at some point.
[18:20:21] <Connor> get away from using cheap a$$ BOB and pport
[18:20:55] <pcw_home> You can probably still use the cheap a$$ BOB with a 5i25 directly
[18:21:15] <pcw_home> (the 7I76 is overkill for most small machines)
[18:21:18] <XXCoder1> Microsoft BOB? ;)
[18:21:19] <skunkworks> the 5i25 acts like 2 printer ports nativly.. I/O wise..

[18:29:45] <skunkworks> Connor, comparing the new trajectory planner in linuxcnc to mach3 (one of the comlaints of linuxcnc) It seems to be very comparable now even though you cannot compare apples to apples very well. (plus no constraint violations.. )

[18:46:03] <skunkworks> normally the limit is the axis starts oscillating...
[18:46:32] <XXCoder1> Ahh thanks for explaining
[18:48:49] <R2E4_> ok, if you leave it where the axis starts oscillating and you adjust I and D to stop the oscillation whcih is catchup error, then it is sitting normal without hunting. Now you can jack up the P again until it starts oscilating again.

[18:58:14] <gene__> I also use FF0 for a thru bias to help center the error band.
[18:58:39] <CaptHindsight> gene__: same question ^^
[18:58:47] <R2E4_> ok. While you are adjusting it intially, in the air, will be significantly diffent offset when a bit is cutting through a hunk of steel on the table.
[18:58:48] <Connor> CaptHindsight: Not yet..
[18:59:11] <gene__> I spose about 2/3rds inch at the workpiece
[18:59:35] <Connor> I'll fire it up tonight and do some testing.
[18:59:46] <Connor> I just got it working on the mill a day or two ago..
[18:59:49] <R2E4_> Skunkworks, yeah I got it straightened out. I added a .1 second timer, to give the brake a chance to engage and it doesnt drop a smidggin....
[18:59:50] <Connor> still need to make a mount for it.
[19:00:01] <CaptHindsight> 0.6" at 640 pixels is 0.001"
[19:00:15] <Connor> I can do closer than .6"
[19:00:24] <CaptHindsight> I have some low cost usb microscopes on the way
[19:00:25] <R2E4_> pcw_home: ok, Leave D at 0
[19:00:31] <gene__> That seems tobe about what I'm seeing.
[19:00:47] <CaptHindsight> 0.6" field of view at 1-2" distance would be nice
[19:01:09] <CaptHindsight> the lens should not be too close to the work surface
[19:01:47] <gene__> Cuz it will get dirty from flying lub.
[19:01:49] <pcw_home> also no I...
[19:02:20] <CaptHindsight> far enough away to be longer than the end mill
[19:02:31] <R2E4_> just drop the P untill it doesnt oscilate?
[19:03:20] <Connor> That would only matter if the camera was mounted all the time... My initial plan was to mount mine in a tool holder.
[19:04:30] <pcw_home> yes drop P until its stable even when jogged
[19:04:41] <CaptHindsight> Connor: I want to mount it offset so it can me used for auto zero as well as viewing the cuts
[19:04:57] <gene__> You want it stiff enough to pick up on the loading. But I am finding that altho Peters SPINx1 is far more linear than a C41, I still need to bend the curve down some at the top end.
[19:05:15] <Connor> yea, I had thought about that.. this one probably won't be able to do that.
[19:05:54] <pcw_home> SPINX1 is better than 1% linear
[19:05:55] R2E4_ is now known as R2E4_awy
[19:06:48] <gene__> That is probably an artifact of the input buildout of your motor controller. If the resistance to the summing junction is low from the put terminal, the sum gets overridden and speed goes way up.
[19:06:53] -!- thomaslindstr_m has quit [Quit: Leaving...]
[19:07:04] <gene__> This is NOT the SPINx1's fault.
[19:07:32] <gene__> Its linear to the limits of my ability to measure it.
[19:08:48] <marmite> man why is it so hard to find ifnromation about spindles for new people in this hobby :D
[19:08:59] <marmite> so hard to find a decent spindle for a samller machine
[19:09:00] <gene__> Using the JT250 controller in a 7x12 as a for instance, its terribly non-linear, but a 10k resistor in series with the input makes a hugfe diffeence.

[19:10:51] <gene__> The input buildout R in this Gemini controller is about 30k and I have not tried adding another 50k between the SPINx1 and the controller, but I suspect that will go quite a ways in linearizing it.
[19:11:05] -!- Loetmichel has quit [Ping timeout: 268 seconds]
[19:11:56] <gene__> I have the SPINx1 set to peak at 15 volts, which is abut 1.5X what the gemini needs, so there is room to play :)
[19:15:10] <gene__> marmite: ebay has some spindles I am looking at for a quite reasonable price, however I was cautioned that the R8 chcuks, due to the single setscrew mounting, will probably have excessive runnout, so I haven't dropped the card yet.

[21:25:45] <Connor> and is it remap or classic ladder ?
[21:27:25] <JT-Shop> you were asking how to simulate inputs
[21:27:29] <JT-Shop> gnipsel.com
[21:27:43] <JT-Shop> it's classicladder
[21:33:09] <Connor> Okay, so you just have a button for each tool.. does that mean it has 4 sensors? 1 for each tool?
[21:33:14] <Connor> what if only have 1 sensor?
[21:35:18] <JT-Shop> that sim is for a turret with an absolute encoder, you would have to make what ever makes sense for you
[21:35:39] <JT-Shop> if you have one prox then you just need one button to simulate the prox
[21:35:45] <Connor> This is just a prox sensor that indicates once per tool position
[21:36:02] -!- FinboySlick has quit [Quit: Leaving.]
[21:36:23] <Connor> But, I need to simulate the count up/ count down from current tool to new tool

[21:40:14] <Connor> So, use hal encoder for counter <= Use a single gui button to indicate the prox sensor change ?

[22:53:38] <Connor> PetefromTn_: Yes, how many tool slots again ?
[22:53:48] <rob_h> no they could aford the extra cylinder on the changer
[22:53:54] <PetefromTn_> 20 I think I gotta check when I get home.
[22:54:24] <rob_h> dont forget its bidirection so have to rember to carry the count in each direction as such

[22:57:46] <JT-Shop> I think mine is a geneva indexer as well
[22:58:15] <JT-Shop> so plenty of time to stop the motor after the prox is high
[22:58:26] <rob_h> then mine got a 3 phase motor to drive it..
[22:58:40] <PetefromTn_> Honestly I am quite surprised that there have not been other simple umbrella toolchangers done before as every Haas, Fadal, Cincinatti etc has these type changers..
[22:59:04] <JT-Shop> unbrella?
[22:59:07] <rob_h> yea i think i just turned it on for a set time to index it after the bit was seen and added 1 to the count
[22:59:28] <rob_h> maybe others pickup a better machine with random and dont worry lol

[23:01:01] <JT-Shop> random is faster
[23:01:01] <rob_h> twin arm
[23:01:05] <PetefromTn_> never heard it called that.
[23:01:09] -!- rosslyoung has quit [Read error: Operation timed out]
[23:01:12] <JT-Shop> swap tools
[23:01:23] <PetefromTn_> I have heard them called side mount swingarm etc...
[23:01:24] <rob_h> called random due to the tool never goes back into the same pocket number
[23:01:31] <JT-Shop> preposition the next tool then swap it with the one in the spindle
[23:01:35] <rob_h> yea prob EU talk and US talk there ;)
[23:02:02] <PetefromTn_> That was never an option on these machines.
[23:02:02] <JT-Shop> then you have redneck mixed in for a real mess
[23:02:08] Cylly is now known as Loetmichel
[23:02:34] <PetefromTn_> you callin' me a redneck?
[23:02:48] <JT-Shop> me
[23:02:51] <rob_h> lo
[23:03:45] <JT-Shop> seems to determine direction you need to calculate the shortest number between the current and requested tool
[23:04:08] <rob_h> ? u mean what i pasted link for
[23:04:52] <JT-Shop> yea
[23:05:09] <rob_h> yea it does.. was a snippet from the comp i made for CHNC where i put in servo motor
[23:05:33] <rob_h> i started wirtting a comp for when i do my other VMC to linuxcnc but been to bussy to think about converting it
[23:05:44] <JT-Shop> lol me too
[23:05:53] <JT-Shop> I need to play catch up for a while
[23:05:55] -!- arekm has quit [Ping timeout: 264 seconds]
[23:05:55] <rob_h> id like to find a newer machine realy also
[23:06:18] <rob_h> 10k spindle, through spindle coolant , random tool
[23:06:20] <PetefromTn_> what kinda machine is it?
[23:06:34] <rob_h> just bigger leadwell of what i put on youtube
[23:06:39] <JT-Shop> that would be a nice one
[23:06:46] <rob_h> one on youtube is a 540 X travel, other is a 720X travel (mm)
[23:06:54] <R2E4> evening
[23:06:55] <PetefromTn_> That looks like a decent machine on youtube.
[23:07:02] <Connor> is their a trick to get a component to work via name vs number ?
[23:07:10] <Connor> loadrt and2 names=upand,downand
[23:07:12] <Connor> loads it..
[23:07:13] <PetefromTn_> evening
[23:07:24] <Connor> but addf and2.upand servo-thread
[23:07:28] <Connor> says it can't find it.
[23:07:32] <R2E4> I see your working on your ATC
[23:07:42] <JT-Shop> it aint and2 anymore after you rename it
[23:07:50] <PetefromTn_> well Connor is at least I am lost..LOL
[23:08:07] <rob_h> PetefromTn_, is just entertaiing us all while we watch
[23:08:11] <R2E4> uukk! Does Conner travel? lol
[23:08:13] <JT-Shop> Connor, look in Show Hal Configuration
[23:09:03] <R2E4> I was looking on youtube, and mine Y has to travel during a tool change.
[23:09:04] <PetefromTn_> I'm really lucky he lives nearby here. I have been doing machine work for him and he helps me with the retrofit techie stuff....
[23:09:32] -!- tjtr33 has quit [Quit: Leaving]
[23:09:36] <PetefromTn_> so you may need some of the same medicine we need for my machine then I guess.
[23:09:43] <R2E4> My X,Y and Z are done.

[23:09:51] <PetefromTn_> mine as well..
[23:10:02] <R2E4> yeah, but there's nop doctor in these here parts....
[23:10:05] <PetefromTn_> I have been making parts with the machine for awhile now...
[23:10:47] <R2E4> sI have to dothe homingand test the limits before I run a file on it.
[23:11:03] <PetefromTn_> that's for sure..
[23:11:12] -!- patricka_ has quit [Remote host closed the connection]
[23:11:41] <PetefromTn_> I really like the homing setup on linuxCNC. there are many scenarios you can setup including home to index.... which is nice.
[23:12:40] <R2E4> yeah, I was reading that but didnt understand exactly what it was
[23:13:38] <PetefromTn_> well basically the encoders have an index pluse once in a revolution, you home to the switch and then the axis backs off from there to the index pulse and calls that home.
[23:13:55] <PetefromTn_> It is possibly more accurate than the switch itself.

[23:16:56] <R2E4> https://www.youtube.com/watch?v=lmvUlqs67dk thats a machine like mine doing a tool change
[23:17:41] <R2E4> PetefromTn_: I put a relay and delayed the swquence by .1 second, andit fixed my Z dropping issue.
[23:17:55] <Connor> alright.. using updown, and2, or, and not components.. I now have a counter that counts up to 20, wraps to 1, and if I set the direction bit, it counts down.. wrapping from 1 to 20

[23:18:14] <JT-Shop> your almost there
[23:18:58] -!- micges has quit [Ping timeout: 240 seconds]
[23:19:25] <Connor> Yup. Now, to write a O command that decides which direction is shortest, toggles the direction bit, the starts a while loop waiting for the tool changer to run.
[23:19:28] <PetefromTn_> glad to hear you got the Z sorted out. I know you were worried about that.
[23:21:01] <PetefromTn_> Connor I know we need to sit down and discuss the sequencing of the actual toolchange soon. Like I said we need to have not only each movement and sensor actuation but also the negatives of each for safet as well as a time out safety.
[23:21:32] <rob_h> no parting the tool changer off into the work table
[23:21:33] <Connor> Yea.. I'm writing out individual building blocks right now...
[23:22:02] <Connor> I.E. a subroutine that advances the tool to the appropriate pocket.
[23:22:22] <Connor> a subroutine that checks the ram sensors and actuates the ram accordingly.
[23:22:32] aude_ is now known as aude
[23:24:32] <asah> how have people setup their pwm frequency on mesa 3pwmgen ? I cannot see .frequency pin as listed in the docs.
[23:29:28] <rob_h> you mean? setp hm2_[HOSTMOT2](BOARD).0.pwmgen.pwm_frequency 192000
[23:29:28] <R2E4> PetefromTn_: you homing is using index?
[23:30:28] <Connor> now, to figure out the math of choosing the shortest path...
[23:30:34] <Connor> for the direction bit.
[23:30:50] -!- rosslyoung has quit [Ping timeout: 246 seconds]
[23:31:24] <asah> rob_h: no that does not work. neither pwm_frequency nor frequency show up for me as pins.
