[02:56:37] <diverdude> Hi - I am trying to home my stepper motor using this code: https://paste.ubuntu.com The homing actually works great, however when homed i want to change direction and move back, away from the switch. When I try to do this the motor is not doing anything. What am I doing wrong here?

[04:08:28] <pingufan> Hello.
[04:08:37] <gloops> morning
[04:11:14] <pingufan> I am using an older version of Linuxcnc because newer ones have biggest trouble with OnBoard graphics on my PC. (I have no other choice.) What I wonder about is: When connecting from remote (tigervnc) to see the progress of the job, it worked years ago fluently, but now I see only obe "screenshot" without any further updates.
[04:11:28] -!- rmu_ has joined #linuxcnc
[04:11:57] <pingufan> Can I tweak something to make it working again?
[04:12:21] <gloops> i cant help with that

[04:14:42] -!- Tecan- has joined #linuxcnc
[04:14:48] <pingufan> gloops: Which software do you use for generating Gcode?
[04:16:36] <pingufan> I currently use Cut-2D (vectric), but it is a windows one and has some really bad effects. I would like to use something very similar natively on Linux. 2.5D is sufficient for my needs.
[04:17:27] <gloops> i use vectric set for emc^2 g64 arcs
[04:18:26] -!- Tecan has quit [Ping timeout: 260 seconds]
[04:22:07] <pingufan> I do the same.
[04:22:48] <gloops> what are the bad effects?
[04:23:13] <pingufan> My major problem is that it does a rapid move downwards behing tabs. Does not matter in wood or plastic, but Aluminum and harder material???
[04:24:06] <pingufan> Are you using it on Windows or in wine environment on Linux?
[04:24:26] <gloops> ive used it on both, runs the same
[04:25:13] <pingufan> Updating the screen (preview of milling process needs 2 clicks on my system.
[04:25:17] <gloops> it will rapid at the maximum velocity set for the axis
[04:27:15] <pingufan> Indeed. So I push the 1mm endmill into aluminum at 900mm/min. Very brutal.

[04:27:18] -!- W1N9Zr0 has joined #linuxcnc
[04:27:53] <pingufan> And when setting the maximum speed to an acceptable one for this thin endmill, you wait infinitely to finish the job, because then all moves are done so slowly.
[04:28:43] <gloops> any chance of roughing out with a larger tool ?
[04:28:54] <pingufan> Therefore I cannot mill metal with thin tools without risking to break the endmill behind very tab.
[04:30:09] <pingufan> No. This is a modified enfraving machine. No automated tool changes.
[04:30:24] <pingufan> So I need to do everything with one tool.
[04:30:44] <gloops> no need for auto tool change, just generate 2 jobs on the same drawing
[04:31:16] <gloops> i have got auto tool change, i use different tools, i just have to run each procedure as a seperate job
[04:31:19] <gloops> havent got
[04:32:19] <pingufan> Ah! Good idea. Can Cut 2D insert a pause command (M1) ?
[04:33:43] <gloops> say you have a pocket and a profile to do, on the same drawing in vectric create the pocket toolpath, save it alone, then do the same for the profile, make the profile, save that code seperate
[04:33:55] <gloops> run the pocket let it end
[04:34:03] <pingufan> So the machine pauses before cutting out the part. I go there, "continue" the job, and manually hold down that part.
[04:34:06] <gloops> change the tool, load the profile path, run that
[04:34:41] <gloops> pause is not much good because youre going to have to touch off the new tool, unless you know the dimensions exactly and have them loaded
[04:34:51] <pingufan> When using "pocket", it consumes a lot of time to convert all material into chips. :) Therefore I only mill the outside path.
[04:35:33] <gloops> cant you add a 3d graphics card to the PC?
[04:36:49] <gloops> some jobs are slow lol https://www.youtube.com
[04:37:03] <pingufan> I mean: I "pause" the job my a g-code before the last path (cutting through material) starts. Then I continue it under personal control.
[04:37:37] <pingufan> Is this your mill ?
[04:39:12] <pingufan> My mill is 1/2 of this one. :) I have a workspace of 360x310x60 mm
[04:40:55] <pingufan> Back to your question... This is a miniITX board with VIA C7 CPU (Everything onboard). It only has a PCI slot (NOT PCIe!!), nothing else.
[04:42:29] -!- pink_vampire has quit [Ping timeout: 268 seconds]
[04:43:10] <pingufan> The mill is very heavy and has high precision, but it is small. It is a Gravograph VX. I threw out the original electronicsand replaced it by new stepper drivers (Gecko) and self built optocoupler board.
[04:43:15] <gloops> yeah its a router i built
[04:44:31] <gloops> well gotta get to the garage, someone might help with the older version, doesnt seem to be many around here atm
[04:45:05] <pingufan> Nice router. Perfect for such needs. Congratulation.
[04:45:18] <pingufan> I also have to go to my router and watch it...

[05:39:31] <pingufan> Hi, what is the difference between M0 and M1, please? I used M0 in the g-code to pause _temporarily_ the program, regardless if the M1 icon is clicked or not (in GUI). Which key do I have to continue execution? "S" didn't work. "R" started the program from beginning. :(
[05:40:22] -!- Guest31449 has joined #linuxcnc
[05:40:32] <XXCoder> pingufan: m0 is pause period
[05:40:42] <XXCoder> m1 is pause only when m1 pause is enabled
[05:40:52] <pingufan> So I understood.
[05:41:19] <XXCoder> just hit run again
[05:41:37] <pingufan> So M0 is the right command because I have to manually hold down the part in last cutting move.
[05:41:55] <pingufan> What is "RUN"? Key "R" ?
[05:41:57] <XXCoder> m1 is same thing as m0, just you can disable m1 but not m0
[05:42:11] <XXCoder> linuxcnc no idea. work machines I just hit the run button :)
[05:42:57] <pingufan> You mean the button with triangle pointing to the right?
[05:43:03] <pingufan> In GUI?
[05:43:34] <XXCoder> i want to say yes but uncertain. set rapid and feed overrides to zero first
[05:44:55] <pingufan> When moving the mouse over that button, it shows "R" to run program inside a popup hint. But when I press "R" on keyboard, the program starts with first line again.
[05:45:34] -!- Guest31449 has quit [Remote host closed the connection]
[05:45:40] <XXCoder> dammit. no idea for linuxcnc how to "countune" and not start again
[05:47:13] <pingufan> In worst case I will insert a command for manual tool change. Will this automatically turn off/on coolant, spindle, ...?
[05:47:31] <XXCoder> m3 turns on spindle
[05:47:33] <XXCoder> m5 is off
[05:47:40] <XXCoder> coolant lemme try remember
[05:47:51] <XXCoder> m6 m8? not sure lol
[05:48:09] <pingufan> You are close. M7 and M9
[05:48:26] <XXCoder> ok
[05:48:48] <pingufan> I also have M101/102 in use to turn the vacuum on/off by G-Code.
[05:49:33] <XXCoder> http://wiki.linuxcnc.org may be applicable
[05:50:22] <pingufan> Does a manual tool-change from tool 1 -> Tool 1 cause a pause in execution, or will linuxcnc see that it is the same tool and skip pausing?
[05:50:52] <XXCoder> may factors depend on your setup, for example maybe your machine will move spindle up to change position or maybe not
[05:51:03] <XXCoder> BUT it will simply run again afterwards with no tool change
[05:51:29] <XXCoder> however if your machine HAL is set to "no automatic tool change" then it will pause and wait for you to change tool and set length
[05:52:26] <XXCoder> hurco doesnt go to tool change position lol scared shit out of me when it started spinning and moved to part without rinsing
[05:52:42] <XXCoder> it marked the part but didnt break it, and then it rose to starting z position
[05:52:48] <XXCoder> know your machine :)
[06:01:51] <pingufan> Hmm - again, the program started from first line.
[06:02:18] -!- Rob_H has quit [Ping timeout: 264 seconds]
[06:02:22] <XXCoder> look for resume somewhere
[06:03:00] <XXCoder> load a test program that is just few m0s
[06:04:45] -!- syyl has joined #linuxcnc
[06:10:39] <pingufan> Horrible. I see a "clicked" Pause icon. When I click it to continue, the program starts from line one.
[06:11:25] <XXCoder> we are missing something. checked out menus?
[06:11:53] <pingufan> So I have to find a workaround. Can I cause a command prompt which stops program frow until confirmed?
[06:12:31] <XXCoder> m0 should always resume to enxt line and so on
[06:12:34] <XXCoder> same as m1
[06:12:42] <XXCoder> not sure whats happening at your setup
[06:17:40] <pingufan> Me, too. On keyboard, I can press "P" during program execution. Machine pauses then. And when I press "S", it continues. I actually want the same but the "P" should come from the G-Code script.
[06:18:19] <XXCoder> does it also resume when you press "S" at m0 stop?
[06:18:44] <Tom_L> pingufan, http://wiki.linuxcnc.org
[06:20:00] <XXCoder> Tom_L: does S also resume from m0 or m1?
[06:20:48] <Tom_L> i dunno
[06:21:04] <Tom_L> i've been using 'run from line' quite a bit lately
[06:21:15] <Tom_L> right click on the line in the window
[06:21:26] <Tom_L> make sure your spindle is on...
[06:25:28] <Tom_L> https://en.industryarena.com
[06:29:51] <pingufan> I definitely use P/S to manually pause and continue a program, this works. But S did not work from M0/M1.
[06:30:12] <jthornton> morning
[06:30:24] <pingufan> Hi.
[06:30:57] <gloops> if you change the tool during pause, how you gonna touch it off though?
[06:31:12] <gloops> unless you add tool touch off next
[06:33:24] <pingufan> Nonono - you mis-understand. I do not change a tool. I always do everything with one tool. I am only looking for a way on how to temporarily stop program execution until I am there. I have to hold down the part I am milling out, the inner (remaining) material of a cut-trough window.
[06:33:58] <gloops> ahh right, i thought you were trying to stop for a tool change
[06:34:16] <XXCoder> gloops: but he cant resume, only start from first line
[06:34:22] <XXCoder> bit odd
[06:34:32] <XXCoder> m0 and m1 should allow him to do resume but...
[06:34:46] <gloops> that doesnt seem to work for me from the linuxcnc ui either, on 2.8
[06:34:59] <pingufan> No. My problem is that I could not find out how to proceed the job after a M0/M1 command. My Linuxcnc always starts from first line then.
[06:35:12] <XXCoder> its such a basic part of cnc machines. why doesnt resume work?
[06:35:37] <pingufan> Would like to know that, too. :)
[06:35:56] <gloops> i dont know, i remember gregcnc saying he'd not had any luck with it either
[06:36:09] <gloops> we ought to solve this issue, it cost me a lot of time the other week
[06:36:27] <XXCoder> maybe some change broke it
[06:36:38] <gloops> where i could have carried on, but it went back to the start
[06:37:28] <pingufan> In my code, I turn off mist and the vacuum cleaner, then I do "M1". So the machine is very silent and I know that I have to go there. Now I take a stick to hold down the part and want to proceed. So the next commands turn on the cacuum cleaner and mist again, then the normal remaining code follows.
[06:37:48] <pingufan> This is my plan. But I cannot find the right key to resume execution.
[06:38:55] <jthornton> t
[06:41:41] <jthornton> opps no it's s
[06:41:56] <Tom_L> http://linuxcnc.org
[06:42:08] <Tom_L> that should be more current if not the same as the previous wiki one
[06:42:29] <Tom_L> i don't think it's changed
[06:42:37] <gloops> well, i finally got my vertical surface mounted today, 2 months after starting it! funerals, weddings, flu you name it, everything but progress

[06:45:29] -!- Deejay has quit [Quit: bbl]
[06:46:52] <Tom_L> because "S" sure reminds me of 'Resume' :)
[06:47:17] <XXCoder> yeah lol
[06:47:35] <jthornton> r was already used for Run
[06:47:46] <jthornton> reSume
[06:47:56] <XXCoder> but why doesnt Run change to Resume on m0 or m1 stop?
[06:48:09] <XXCoder> all machines at work I use same button for Run to Resume
[06:48:10] <Tom_L> they should have used "S" for "Start program" and "R" for "Resume"
[06:48:32] <jthornton> have to ask the programmer why he did it like that
[06:48:41] <jthornton> change it
[06:49:11] <Tom_L> meh, i'd have to bother you to change the docs :)
[06:49:19] <jthornton> lol
[06:49:27] <jthornton> the docs are wrong anyway
[06:49:39] <jthornton> it says press cycle start to resume

[06:50:48] <Tom_L> lsb_release -a
[06:51:23] <XXCoder> looks like mint Sylvia lemme find out which ubuntu version it matches
[06:51:28] <pingufan> Has a single % sign a special meaning?
[06:51:37] <Tom_L> start or end of program
[06:51:50] <XXCoder> looks like Xenial
[06:51:56] <pingufan> Argh !!!!!! This was the reason!
[06:51:58] <Tom_L> unless you're calculating tax on something
[06:52:13] <Tom_L> yes it needs to be in the program
[06:52:57] <XXCoder> ah so your program ended at first % after top lol
[06:52:57] <Tom_L> maybe for old tape readers? i don't honestly remember
[06:53:03] <XXCoder> Tom_L: yeah basically
[06:53:09] <pingufan> So whitespace is simply a empty line?
[06:53:28] <XXCoder> no any space, there should never be empty line
[06:53:30] <jthornton> http://linuxcnc.org
[06:54:32] <Tom_L> it's da law!
[06:54:36] <XXCoder> wow
[06:54:45] <XXCoder> repos have pretty old ubuntu versions supported
[06:58:27] <pingufan> I need to wait 1 second in my gcode to let the spindle speed up. What command shall I use?
[06:58:45] <jthornton> pause
[06:59:08] <jthornton> or dwell even

[07:09:57] <pingufan> How can I install x11vnc on my cnc mill? It seems that the built-in vnc server is very poor in my version.
[07:10:47] <pingufan> I am almost sure that this is the reason why I cannot watch the desktop from remote.

[07:16:53] <XXCoder> jthornton: I used to have linuxcnc on this pc for testing reasons
[07:17:04] <XXCoder> but I forgot how to add it in such way that its for sim only
[07:17:09] <XXCoder> no RTAI
[07:25:48] <jthornton> http://linuxcnc.org
[07:26:20] <XXCoder> its telling me to install rtai I dont wanna do that
[07:26:25] <XXCoder> ]it wont be running real machine
[07:26:46] <jthornton> 4 options are for stock kernel...
[07:27:26] <XXCoder> I miust be missing it. which section?
[07:27:29] <jthornton> but it doesn't tell you how to get simulation only :(
[07:27:54] <jthornton> http://buildbot.linuxcnc.org
[07:28:09] <XXCoder> yeah thats why I was having issue
[07:28:11] <XXCoder> a second
[07:29:09] <jthornton> geez installing the simulation version should be in the damn docs
[07:30:05] <XXCoder> lucid is latest linux ubuntu version linuxcnc is using right?
[07:30:35] <jthornton> no, linuxcnc uses debian now so stretch is the latest
[07:31:44] <XXCoder> can I change deb http://buildbot.linuxcnc.org stretch 2.7-rtpreempt to deb http://buildbot.linuxcnc.org stretch 2.7-sim ?
[07:32:50] <jthornton> give it a try
[07:34:27] <XXCoder> http://dpaste.com
[07:35:18] <XXCoder> looks like I gonna install em myselg
[07:35:27] <jthornton> linuxcnc-uspace:???
[07:35:46] <XXCoder> yeah no linuxcnc install weird
[07:39:29] <pingufan> Can somebody tell me how to install x11vnc on my cnc mill? (Ubuntu 8.04 Hardy)
[07:39:41] <pingufan> I cannot use a newer linux on my hardware.
[07:41:10] <pingufan> normal vnc support is very poorely working, I had same effects on openSuSE with KDE, too, while x11vnc on openSuSE works perfectly. So I want to do the same on linuxcnc machine, but I am not familiar with ubuntu.
[07:44:58] <XXCoder> "E: Package 'linuxcnc' has no installation candidate" dammit
[07:50:11] <gloops> G4 P(x)
[07:50:35] <gloops> ahh sorry, scroll was stuck further up lol
[07:51:20] <pingufan> gloops: I tried G4 P5 but this rised an error. (Currently a job is running, cannot test.
[07:52:10] <gloops> i use that with vectric code, on a seperate line, it works ok for me
[07:53:21] <pingufan> So an example is G4 P5 for 5 seconds delay?
[07:53:35] <gloops> you can send the spindle status from the vfd to hal, i had that working before but forgot how to do it - it wont move then till spindle is at speed
[07:53:48] <gloops> yeah that should work pingufan
[07:54:06] <XXCoder> "E: Package 'linuxcnc-sim' has no installation candidate" dammit
[07:54:17] <pingufan> Then I try again. This was possibly a problem caused by a previous error.

[08:01:27] <pingufan> Whar rpm does your spindle?
[08:01:39] <pingufan> I am close to 16000 rpm
[08:01:47] <gloops> top speed is 24k, i dont use that much though
[08:01:58] <rmu_> XXCoder: if apt says "no installation candidate" you need to activate a source repository
[08:02:02] rmu_ is now known as rmu
[08:02:14] <gloops> im usually around 16k too
[08:02:25] <pingufan> You use relatively thick tools - compared to mine (1-3 mm at most).
[08:02:57] <jthornton> XXCoder: my guess is you need to build a deb for your os and install that
[08:03:30] <gloops> yeah, 3mm is usually small enough for any detail i want to pick out in wood, and then anything up to 25mm if i want to get rid of stuff quick
[08:03:30] <XXCoder> rmu: I didnt add source, lemme see if that works
[08:03:35] <pingufan> But I thought of buying a HF spindle of 300W in China. Problem is: The reciption for belt-driven my spindle is ø35 mm.
[08:04:22] <XXCoder> no change rmu
[08:04:22] <pingufan> Find a spindle with this diameter... :(
[08:05:18] <gloops> well, you can get the 3 phase chinese spindles and vfd for around £150 now, which is a lot of money really

[12:24:36] <Connor> Anyone help my calculate the diameter needed for a heat-shrink fit for a aluminum hub on a 1/8" shaft? The hub is 3mm, and I can ream it i exactly .125 or .1245 (the only two I have) or leave it as is..
[12:26:11] <jdh> try the small one first?
[12:30:20] -!- tachoknight has quit [Remote host closed the connection]
[12:30:45] -!- tachoknight has joined #linuxcnc
[12:32:44] <Connor> Hmm.. Looks like, if I ream it to .1245" and heat the alumnum up to 350F, I can get exactly .125" of a fit.
[12:33:46] <Connor> I can't get there from the 3mm size hole with no amount of heat.. as it would melt.. :)
[12:34:02] <Connor> so, .1245" reamer it is and some heat..
[12:34:10] <Connor> probably from a hot plate or something.
[12:36:44] -!- beachbumpete1 has quit [Quit: http://quassel-irc.org - Chat comfortably. Anywhere.]
[12:37:02] <cradek> your 1245 is probably a dowel pin reamer, meant for a press fit of a .1252ish dowel pin
[12:37:41] -!- MarcelineVQ has joined #linuxcnc
[12:38:09] <Connor> https://www.mcmaster.com
[12:38:10] <cradek> with .0007" interference you can simply press them together and that's the usual thing to do
[12:38:53] <Tom_L> you can always cool the other part too
[12:39:00] <Tom_L> freeze one, heat the other
[12:39:08] <Connor> It's going on a Brushless outrunner motor (like the ones for drones).. I wasn't wanting to press it on.. I need to file a flat on the shaft too.
[12:39:13] <cradek> is your shaft really .1250?
[12:39:31] <Tom_L> i bet it's .125001
[12:39:50] <Connor> I've not put the mic on it yet.. but, it's suppose to be 1/8" :) I'll double check it before I do any of this.
[12:39:51] <cradek> actually I bet it's .1247 and both these reamers are way too big
[12:40:40] <cradek> so use the smaller one, and when it's still loose, use loctite :-)
[12:41:08] <Tom_L> or knurl it
[12:41:08] <Connor> Using loctite anyway. It's for a 3lb combat robot. :)
[12:42:52] <cradek> when you mic the shaft, mic the reamer too
[12:43:24] <Connor> ok. I don't have my mic with me.. All I have here at the house is HF Calipers..
[12:43:40] <Connor> So, I'll check it later tonight.

[12:47:58] <gregcnc> hammer it together using the HF calipers
[12:48:36] <Connor> I do have to say, the HF digital micrometers aren't all that bad for what you pay for them.. their calipers are crap though. Almost every single one I've had has a high spot or something so that if you tighten up the thumb screw, it stops mid way..
[12:50:58] <Rab> The (metal) calipers are pretty good for being $10. Mine are several years old, so maybe quality varies.
[12:51:33] <jdh> my $10 HF ones measured calibrated gauge blocks identically to my mitutoyo (both half thou)
[13:02:00] <Connor> The measure okay.. They're just not as smooth.. and sometimes not repeatable..

[14:59:55] <DaViruz> i have the file at work though :/
[15:00:01] <DaViruz> so it'll have to wait.. :)
[15:00:04] <miss0r|office> hehe
[15:00:32] <miss0r|office> I'll wait ;)
[15:00:46] <JT-Shop> lol the jointer my buddy gave me was made June 1933
[15:01:05] <jdh> with fine american steel?
[15:01:44] <JT-Shop> I quess, it has 1/16" thick knives so hard to find new ones
[15:02:00] <jdh> you need a grinder
[15:02:23] <syyl> everybody needs a surfacegrinder!
[15:02:33] <DaViruz> indeed
[15:02:41] <miss0r|office> Agreed :)
[15:02:45] <JT-Shop> I have a Brown & Sharpe 612
[15:02:48] <DaViruz> i need space for one first though :/
[15:02:51] <syyl> perfect!
[15:02:53] <syyl> :D
[15:03:00] <miss0r|office> Glad you didn't have it... DaViruz:D
[15:03:13] <gloops> cant beat heavy metal
[15:03:18] <JT-Shop> I guess some 3/32" thick knives and a bit of time I'll be in good shape
[15:03:24] <DaViruz> me too to be honest, having more space would probably not be good for me :)
[15:03:30] <syyl> \m/
[15:03:36] <miss0r|office> gloops: Unless you are talking music, I would call it 'old iron' ;)
[15:03:58] <miss0r|office> syyl: cool down. He didn't mean it! He don't know what he is saying ;)
[15:04:53] <miss0r|office> also.. if I ever felt like a hacker from the matrix, it should be now. I am looking at four screens, placed in a semicircle in front of me.
[15:05:17] <miss0r|office> Three for my normal workstation here, and one, quite massive box, with a touchscreen in it, I am setting up for the CNC
[15:09:13] <miss0r|office> Also.. the ventilator in the cnc controller here is quit loud in my office. hehe
[15:12:24] <JT-Shop> when I bought the 612 (very cheap) the owner made a comment I hope you know how to make it work...
[15:13:06] <JT-Shop> when I got it home I took the table off and the rollers were all facing the same way... no wonder he could not get it to work with a unlevel table
[15:13:46] <Tom_L> JT-Shop how wide and long?
[15:14:03] <Tom_L> https://www.routerbitworld.com
[15:14:11] <JT-Shop> 612
[15:14:15] <JT-Shop> 6x12
[15:14:31] <Tom_L> those are only 8 wide
[15:14:36] <JT-Shop> ok the jointer knives are 6" x 5/8" x 1/16"
[15:14:49] <Tom_L> cut 2" off then and you're golden
[15:15:16] <JT-Shop> yea I saw them but I just ordered some 6" x 5/8" x 3/32" and I'll grind them down to 1/16"
[15:16:13] <Tom_L> they may actually have the 6" as well
[15:16:40] <Tom_L> https://www.amazon.com
[15:17:02] <Tom_L> err no those are 1/8"
[15:19:17] <miss0r|office> Setting up linuxCNC here. How come I am limited to 2000mm/min velocity?
[15:21:39] <cradek> probably because of a misconfiguration, but you need to tell us a lot more to get meaningful help.
[15:22:34] <miss0r|office> Well. There isn't alot more to tell :) This is the second page of the pncconf wizard. And I am only able to type in 2000mm/min in the textbox
[15:22:47] <miss0r|office> It won't let me enter a greater number
[15:23:02] <cradek> aha that is a lot more information
[15:23:19] <miss0r|office> alright, it is :)
[15:23:33] <cradek> if there is a bug in pncconf limiting you to that, you can edit your config (ini file) by hand after you are done in pncconf
[15:23:44] <miss0r|office> That is true. :)
[15:24:47] <cradek> <object class="GtkAdjustment" id="max_lin_vel_adjust">
[15:24:47] <cradek> <property name="upper">2000</property>
[15:25:03] <miss0r|office> so not a bug.
[15:25:04] <cradek> seems likely it's this, which might be a bug
[15:25:13] <cradek> I don't know why it's this number
[15:25:21] <miss0r|office> It might be. Surely I can't be the first one to wanna go faster than that? :)
[15:26:09] <cradek> are you sure that's not per second?
[15:26:24] <miss0r|office> On the caption it says mm/min
[15:27:06] <cradek> it might have been chosen for inch (2000 inches/min) and then incorrectly also applied in mm
[15:27:16] <cradek> either way go ahead and continue, and edit the file afterward
[15:27:37] <miss0r|office> That sounds more realistic, although 2000 inches/min is not mindblowing fast either
[15:28:14] <cradek> I'm just guessing why the number is there
[15:28:23] <miss0r|office> Indeed. :)
[15:28:34] <cradek> if you don't find another reason for it, and it's just an arbitrary and wrong constraint, please file a bug against pncconf explaining what you found
[15:29:12] <miss0r|office> I will
[15:29:15] * miss0r|office is taking a note
[15:29:23] <cradek> cool thanks!
[15:30:02] <miss0r|office> No problem. That is what the opensource community is all about ;)

[16:08:09] <phipli> https://www.youtube.com
[16:08:13] <pcw_mesa> There are a number of pncconf constants that assume inches unfortunately
[16:08:20] <XXCoder> CaptHindsight: it works fine if you make new one outside Path?
[16:08:57] <syyl> you could have finished that sentence after "crashes" ;)
[16:09:46] <CaptHindsight> XXCoder: didn't crash when I had a part already open
[16:10:34] <XXCoder> thats bit strange bug I guess Path module expects Body to already exist or something
[16:11:33] <XXCoder> seems to work fine here. around latest 0.17
[16:14:30] <CaptHindsight> when using 2 LPT cards with StepConfig do you put both addresses in the box with a space between them?
[16:15:18] <CaptHindsight> think I ended up just editing by hand
[16:15:33] <XXCoder> I think theres 2 boxes? been a while since I configured
[16:16:31] <CaptHindsight> I recall a checkbox for either 1 or 2 ports then on the port config page for #2 there was no box for an address
[16:17:24] <CaptHindsight> was just using it to get started anyway
[16:17:58] <XXCoder> my machine was so simple I could just use configurator lol
[16:19:39] <CaptHindsight> temporarily using steppers to control valves until I have the solenoid motors
[16:20:56] <miss0r|office> I am doing a small test with the 'halrun' command. I followed the instructions given by andypugh in this link: https://forum.linuxcnc.org . However, I am not sure what I am looking it. I would think there should be more I/Os available to me. Should I load a 7i77 as well?
[16:22:27] -!- Roguish has quit [Quit: ChatZilla 0.9.92-rdmsoft [XULRunner 35.0.1/20150122214805]]
[16:23:06] <miss0r|office> Basically, all I want to do for now is to be able to light up a signal lamp located on an output of the 7i77. but reading the list in the halrun I cannot see the outputs of the 7i77 board.
[16:38:22] -!- sgsabbageBq has joined #linuxcnc
[16:41:34] <JT-Shop> miss0r|office: you can't see the 7i77 led's from hal IIRC
[16:41:47] <miss0r|office> I figured it out. Apparently I forgot to set the output on the 5i25 card
[16:42:03] <miss0r|office> so I wasn't even registering the 7i77 :]
[16:42:18] <miss0r|office> (set the two jumpers to supply the 7i77 with 5 volts)
[16:42:55] -!- sgsabbageBq has quit [Remote host closed the connection]
[16:43:06] <miss0r|office> so now I have a massive & noisy box, that allows me to turn on and off an LED with a touchscreen... What a time to be alive :D
[16:45:55] <CaptHindsight> set steppers to squeal mode + microphone, amp and speakers set to 11 = worlds most annoying sounds
[16:46:11] <miss0r|office> now why would I do that then? :D
[16:46:21] <miss0r|office> also, no steppers in this setup; only servos
[16:46:56] <CaptHindsight> keep kids off the lawn, bear repellent, etc

[20:25:13] <enleth> CaptHindsight: "play well with Blender" is a pretty huge deal
[20:25:34] <enleth> just because two pieces of software are written in the same language doesn't mean squat when it comes to interoperability
[20:26:52] <enleth> Blender has an enormously complex internal data model that includes the UI itself as well as the actual scene, that's a... pretty unorthodox design

[22:18:52] <jdh> spindle vfd control works much better with the proper wires connected.
[22:27:47] <Tom_L> i would imagine so
[22:27:56] <Tom_L> got it figured out ehh?
[22:28:36] <Tom_L> you should post your model and what you did somewhere
[22:39:04] <jdh> https://github.com
[22:39:57] <jdh> That could use some sample motion.spindle-foo info and the few params you have to set in the vfd.
