06:12 AM Tom_L: You know all about that
06:20 AM JT-Cave: yup
06:21 AM Tom_L: C8 update?
06:39 AM JT-Cave: status is still 3000 and TPW is still 5/15
06:41 AM JT-Cave: I'll call Phil Friday to see if any update shows on the GM Work Bench

11:55 AM Unterhaus__: I'm still confused about getting lcnc to warm up the bed and nozzle on a 3d printer before printing.
11:56 AM CaptHindsight[m]: Unterhaus__: which part is confusing?
11:57 AM Unterhaus__: I don't have a lot of 3d printer experience, but on mine you can heat things up separately from the gcode
11:57 AM Unterhaus__: I suppose it could just wait until everything is up to temperature
11:57 AM Unterhaus__: like waiting for spindle speed
11:59 AM ZincBoy[CAON][m]: You could use the Near component and tie that to the motion enable. Or use the M66 wait on input in your gcode to delay until the Near output becomes valid.
12:00 PM Unterhaus__: that sounds reasonable
12:11 PM Unterhaus__: can I just add a vcp to axis to start the bed/extruder heaters and control their temperatures independent of gcode?
12:12 PM ZincBoy[CAON][m]: Sure. That is the nice thing about linuxcnc. You can make it do pretty much whatever you want 🙂
12:21 PM Unterhaus__: I have thought of having a remora board hooked up to a mesa just for the temperature reading/control
12:33 PM CaptHindsight[m]: Unterhaus__: https://github.com/SebKuzminsky/linuxcnc-hal-teensy older options
12:35 PM Unterhaus__: teensy doesn't have the circuitry built-in
12:35 PM CaptHindsight[m]: no?
12:36 PM Unterhaus__: does it?
12:37 PM CaptHindsight[m]: Unterhaus__: if you look on the forums we also found several boards made for GRBL that have ARM micros and all the CNC glue gun IO's that by now work with LCNC, let me find a link
12:38 PM Unterhaus__: that's not remora?
12:39 PM Unterhaus__: the remora thread has to be the longest on on the forum, doesn't it?
12:40 PM CaptHindsight[m]: starts around here, it's a tangent to the main thread: https://forum.linuxcnc.org/18-computer/46077-potential-all-in-one-single-board-computers?start=20#251933
12:41 PM CaptHindsight[m]: Unterhaus__: Remora attracted lots of low budget cnc glue gun tinkerers
12:41 PM CaptHindsight[m]: so you could keep your low budget hardware and run LCNC
12:42 PM Unterhaus__: it probably would be over 100 pages if rpis didn't cost so much
12:42 PM CaptHindsight[m]: Rpi's are already the past
12:42 PM Unterhaus__: I'm not convinced many people are running glue gun printers with lcnc or there would be more people whining about how difficult it is to set up
12:42 PM CaptHindsight[m]: there are lots of newer, faster and available boards now
12:43 PM CaptHindsight[m]: they all complain on the forums
12:43 PM Unterhaus__: I saw you had lcnc running on some alternat board
12:44 PM CaptHindsight[m]: rk35xx boards
12:44 PM Unterhaus__: is that the best option currently?
12:44 PM CaptHindsight[m]: also a newer Odroid amlogic https://forum.linuxcnc.org/18-computer/48113-odroid-as-raplacement-for-raspberry-pi
12:45 PM CaptHindsight[m]: find another hobby :)
12:45 PM tiwake: looks like banks are taking a huge dump today
12:45 PM CaptHindsight[m]: i haven't touched any of this in months
12:46 PM ZincBoy[CAON][m]: lcnc is not that great for a 3d printer controller. Klipper is way better with the higher order path planner. It can be used but the performance is on the level of old marlin firmware. The only reason to use lcnc for a 3d printer is if you want to experiment with unique kinimatics or integrating special automation functions.
12:46 PM CaptHindsight[m]: maybe in the fall
12:46 PM CaptHindsight[m]: ZincBoy[CA, ON]: :p
12:47 PM Unterhaus__: isn't there a klipper variant that has better performance?
12:47 PM CaptHindsight[m]: Unterhaus__: see what you like, Linux is the usual mess on ARM, nobody wants to send the time to really fix anything right, just patch on top of patch
12:48 PM CaptHindsight[m]: send/spend
12:49 PM Unterhaus__: that issue is why I am inclined to stick with rpi, the alternates seem to be dead-ends mostly
12:49 PM ZincBoy[CAON][m]: Of lcnc? I know there have been ongoing efforts to add a higher order path planner to lcnc but I have not seen any that are past the prototype stage.
12:49 PM Unterhaus__: I was thinking of mainsail
12:49 PM CaptHindsight[m]: Unterhaus__: https://forum.linuxcnc.org/18-computer/48079-can-the-opi5-be-configured-to-run-lcnc works pretty well
12:51 PM Unterhaus__: I could buy a pc for that much
12:51 PM Unterhaus__: in the before times, I could buy a pc from salvage and a mesa board for that much
12:52 PM Unterhaus__: granted, the 3dp guys would look at me funny
12:53 PM ZincBoy[CAON][m]: That is the problem with most of the sbc options. They end up being the same price as a PC but have all sorts of odd quirks and compatibility issues.
12:55 PM Unterhaus__: I have a nuc that I should check for latency. I bought it because it had 2 ethernets
12:57 PM Unterhaus__: I see klipper punts on accel limits for delta printers just like you have to do on lcnc
01:06 PM Unterhaus__: cakeslob would be mad at me if I put klipper on the sk1.4 he gave me :)

01:29 PM jym: Morning
01:30 PM JT-Shop: yo
01:31 PM jym: ...ho ho and a bottle of rum
01:33 PM jym: Just installed a new IRC client, gonna disconnect/reconnect to see if I configed it right. brb
01:36 PM jym: Seemed to work -shrug-
01:37 PM roycroft: not much needs to work
01:37 PM roycroft: you type stuff
01:37 PM roycroft: you read stuff
01:37 PM roycroft: then you type more stuff
01:37 PM roycroft: :)
01:37 PM jym: Reading is hard, so is breathing and thinking at the same time
01:40 PM roycroft: maybe you can have brainhelpgpt and bodilyfunctionsgpt help you with that stuff
01:41 PM jym: roycroft, Tequila sounds simpler
01:42 PM * roycroft can't handle te-kill-ya any more - he's too old for medicine that strong
01:43 PM roycroft: a wee dram still helps, though
01:46 PM * JT-Shop looks at a bottle of Remy Martin and falls asleep...

02:45 PM santydofus201425: hey guys i've been trying to change the language of the error messages from linuxcnc to portuguese for a while now
02:45 PM santydofus201425: i have this files for translation someone posted on github
02:45 PM santydofus201425: https://github.com/araisrobo/linuxcnc/blob/master/src/po/pt_BR.po
02:46 PM santydofus201425: and i tried to do the msgmerge from pt_BR.po to linuxcnc.pot but no matter what i try, its still in english
02:49 PM JT-Shop: did you change your locale?
02:52 PM Tom_L: I did :)
02:52 PM JT-Shop: lol
02:52 PM JT-Shop: how's the weather?
02:53 PM Tom_L: 87F
02:53 PM Tom_L: Partly overcast
02:53 PM JT-Shop: windy here
02:54 PM Jymm: 85 and windy here in AZ
02:54 PM Tom_L: Amber cove
02:54 PM Tom_L: DR
03:01 PM Tom_L: Just now shoving off
03:01 PM JT-Shop: where to?
03:02 PM Tom_L: San Juan by 10 Am
03:02 PM JT-Shop: nice
03:02 PM JT-Shop: we have been there a few times
03:03 PM Tom_L: 14th century forts etc
03:03 PM JT-Shop: yup, we visited it
03:03 PM Tom_L: Fly or other?
03:03 PM JT-Shop: vly
03:03 PM JT-Shop: fly
03:05 PM Tom_L: Takin the slow lazy way
03:22 PM -!- #linuxcnc mode set to +v by ChanServ
04:10 PM Jymm: Hmmm, I got disconnected
04:29 PM CAKESLOB_w: Unterhaus__ I wouldnt be mad, I cant give you something and tell you to only use it my way
04:30 PM CAKESLOB_w: I wouldnt be happy, but do what ever. Im just hoping out of the 20 boards I get at least 3 new people
04:31 PM CAKESLOB_w: but I never said 3dp on linuxcnc.....or anyhting on linuxcnc would ever be easy
04:32 PM CAKESLOB_w: that was the basis of my lobbying campaing , "give free shit to these smart guys"
04:33 PM CAKESLOB_w: But yeah, 3dp isnt ideal on linuxcnc, part of the plan was to get more smart guys using it, so we can make it better.
04:43 PM CAKESLOB_w: I think theres some m codes remaps for the heater in the 3d-printing repo you were looking at, and some pyvcp examples. Ive been doing a 3dprinter thing for axis, but ive been doing remora shit lately
04:46 PM Lcvette[m]: Just had a weird occurrence
04:46 PM Lcvette[m]: Z axis started cutting deeper on a part
04:47 PM CloudEvil: Not because you forget to tighten the collet?
04:47 PM Lcvette[m]: It was like the 9th set i ran a d all preceding were lerfect
04:47 PM Lcvette[m]: It was a chamfer mill
04:48 PM Lcvette[m]: I am gonna check that but seems unlikely
04:51 PM * Lcvette[m] uploaded an image: (203KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/VljqjVlNTBFgjUCMFrPGMNsw/IMG_20230502_175041940_HDR.jpg >
04:52 PM CloudEvil: Sure the part is mounted flat?

04:57 PM XXCoder: CAKESLOB_w: you was giving away controller boards for linuxcnc machines correct? I think its cool
05:01 PM Lcvette[m]: Nice call, part was not flat
05:01 PM Lcvette[m]: That makes me feel much better

05:21 PM JT-Woodshop: Lcvette[m], the BG plant has a build your Z06 motor at the plant option now
05:22 PM Lcvette[m]: nice
05:22 PM JT-Woodshop: they put you in an area with a tech and bring you the parts
05:22 PM Lcvette[m]: lol
05:23 PM Lcvette[m]: thats pretty cool honestly
05:23 PM Lcvette[m]: tell them to upgrade you to the Z06
05:23 PM Lcvette[m]: 😄
05:24 PM JT-Woodshop: no thanks, I'd love to build the engine but don't want to wait until next year to get my C8
05:34 PM Lcvette[m]: True
05:35 PM Lcvette[m]: <XXCoder> "knowing is always good" <- For certain I'll take operator error all day, that's a 2 second fix
05:35 PM XXCoder: :)
05:36 PM JT-Woodshop: shiny part!
05:36 PM CAKESLOB_w: XXCoder , thanks, yeah I brought 20 to the linuxcnc meeting, but not because everything is great and easy, I figured it was the best way to get power-users on board on board with the project. I cant force everyone to like it, so im hoping to get at least 3 people using it, and at least one that can help with stuff
05:37 PM XXCoder: good luck with that :)
05:38 PM CAKESLOB_w: thanks, my campaing isnt finished yet though
05:38 PM JT-Woodshop: what are you building?
06:15 PM Lcvette[m]: JT-Woodshop: kit parts
06:15 PM Lcvette[m]: For little mill conversations
08:24 PM Unterhaus__: I was just looking at the sheldon mailing list and someone gave bad advice about lcnc
08:25 PM roycroft: what sheldon user has ever heard of cnc?
08:25 PM roycroft: oh, wait, i own a sheldon horizontal mill
08:25 PM roycroft: but i'm not using it
08:26 PM Unterhaus__: Gene Heskett mentioned that he uses lcnc to drive his sheldon
08:26 PM Unterhaus__: and also Jon Elson is a Sheldon owner
08:27 PM Unterhaus__: I was a bit surprised that the sheldon folks don't care that Gene did that to his lathe
08:27 PM roycroft: did he do it under the radar?
08:27 PM roycroft: because yeah
08:27 PM Unterhaus__: he is pretty vocal about it on the mailing lists
08:27 PM roycroft: i've met sheldon owners who go ballistic if you repainted your mill the wrong shade of grey
08:28 PM roycroft: and i kind of get where they're coming from
08:28 PM roycroft: they're really nice machines for what they are
08:28 PM Unterhaus__: they would have died if they saw the way my lathe was painted then
08:28 PM roycroft: and come from the peak of our mechanical industrial period
08:29 PM roycroft: and are very nicely designed and built
08:29 PM XXCoder: reminded me of that vw beetle that was painted in awesome black trims and sunlight yellow
08:29 PM XXCoder: it was painted with house paints.
08:29 PM roycroft: it probably looked great at 30 feet
08:29 PM Unterhaus__: mine was probably painted with house paints. Several shades of green
08:29 PM XXCoder: likely
08:29 PM Unterhaus__: did not look good at 30 feet
08:30 PM Unterhaus__: my sheldon that is
08:31 PM Unterhaus__: I think it was originally grey
08:31 PM roycroft: i think almost all sheldons were originally grey
08:31 PM roycroft: some weren't, but the overwhelming majority were, i believe
08:31 PM Unterhaus__: I don't think I have seen any evidence of the original paint
08:32 PM roycroft: my sheldon mill isn't running, and never has since i got it
08:32 PM roycroft: the stand was missing, so i got the mill and the adjustable-speed motor
08:32 PM roycroft: i got a nice stand for it, but never got it all together
08:32 PM roycroft: i'm thinking about selling it now, to reclaim a little real estate in my shop
08:33 PM Unterhaus__: I wouldn't mind a horizontal mill
08:33 PM roycroft: but it's a nice little machine
08:33 PM Unterhaus__: I don't think I can sell my bridgeport
08:33 PM roycroft: i'm really hesitant to let it go
08:35 PM bjorkintosh: https://www.youtube.com/watch?v=hpJ6anurfuw
08:35 PM roycroft: the motor is one of those that varies the speed by squeezing the sheave sides in and out
08:35 PM roycroft: and it has a really weird motor mount
08:36 PM roycroft: that's a big reason i never got it running - i need to fabricate the mount and also make a linkage for the speed control, which is mechanical, of course
08:36 PM roycroft: plus, it's a 3 phase motor, and i got it before i was dealing with vfds
08:37 PM roycroft: i think it would be easier to just get a standard 3 phase motor and a vft
08:37 PM roycroft: vfd
08:37 PM roycroft: but i could so use the space it's taking up
08:37 PM Unterhaus__: my bridgeport variable speed head is normal except that the speed change wheel was swapped for an air turbine
08:39 PM Unterhaus__: I need air for the knee, which somehow is assisted by an air cylinder built into the base
