12:19 AM Rhine_Labs: Offically out of transformers for the old Tormach boards,
12:33 AM Rhine_Labs: Guy bough machine on Craigslist for 3k he got a good deal.
12:38 AM Rhine_Labs: Was baord was dead. Very common failure on the older units.
01:12 AM Deejay: moin
02:46 AM lcnc-relay: <harpgreen@discord> Guys, is pyvcp only for Axis interface? I want to add sidebar to gmoccapy with pyvcp syntax, but it does not work... is it possible to use pyvcp (i mean the html-like language thing) to customize the interface?
02:47 AM lcnc-relay: <harpgreen@discord> +gmoccapy
03:06 AM lcnc-relay: <travis_farmer@discord> Morning
03:08 AM lcnc-relay: <travis_farmer@discord> harpgreen@discord most of the crew are likely sleeping right now. where i am it is only about 4am 😉
03:08 AM lcnc-relay: you could design a whole interface with FlexGUI 😉
03:12 AM lcnc-relay: <harpgreen@discord> travis_farmer@discord: tks for the reply😁 . I'm afraid I can't design a new interface but only modify the gmoccapy, because the machine in our lab have used gmoccapy since years ago, I'm a new worker here, I was asked to add a sidebar to gmoccapy to achieve more functions..
03:27 AM lcnc-relay: <rs> harpgreen@discord: did you look at docs? specifically https://linuxcnc.org/docs/html/gui/gmoccapy.html#gmoccapy:configuration-of-tabs-and-side-panels ?
03:29 AM lcnc-relay: <rs> completely changing GUI might be a bit disruptive. PB only runs on full HD screens.

09:58 AM lcnc-relay: <skunkworks8841@discord> copper power distribution from the K&T original control..
09:58 AM lcnc-relay: <skunkworks8841@discord> I need a bit of copper sheet
10:03 AM lcnc-relay: <huursabg@discord> https://i.ebayimg.com/images/g/HkgAAOSw3xJVbzVk/s-l1200.webp
10:03 AM lcnc-relay: Would the lpt port header found on some of the modern motherboards work when using this adapter
10:03 AM lcnc-relay: <skunkworks8841@discord> maybe.. I have some HP's with the header - but I bought the official hp cable/plug
10:07 AM Tom_L: more than likely yes
10:07 AM Tom_L: i got one recently and it worked fine
10:16 AM Tom_L: https://www.amazon.com/gp/product/B009JXK5UE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
10:16 AM Tom_L: that's the one i got and it worked fine
11:02 AM lcnc-relay: <rs> i would check first if there really exists something resembling traditional LPT port. it could also be USB-parallel adapter integrated on mainboard which would be unusable.
11:02 AM lcnc-relay: <rs> (IO-port)
11:04 AM lcnc-relay: <rs> skunkworks8841@discord: what kind of monster machine is that. that looks as somebody ripped it from power distribution of a whole factory floor.
11:07 AM lcnc-relay: <skunkworks8841@discord> lol... It was a GE NC control that originally ran the K&T
11:07 AM lcnc-relay: <skunkworks8841@discord> 2ftX4ft by about 8 ft tall

11:22 AM lcnc-relay: <rs> skunkworks8841@discord: that looks like a bunch of discrete opamps
11:25 AM lcnc-relay: <skunkworks8841@discord> yep.. germanium transistors
11:26 AM lcnc-relay: <skunkworks8841@discord> no integrated curcuits..
11:27 AM lcnc-relay: <rs> that era is gone... can't use lead-free solder on those ;)
11:50 AM Tom_L: discord file bridge is borked again
11:52 AM xxcoder: it handles directly linked images wrongly it loooks like, but its same image as earlier direct linkl
11:55 AM lcnc-relay: <huursabg@discord> does the cpu benchmark score indicate any of the jitter i shud get
12:19 PM lcnc-relay: <skunkworks8841@discord> I don't think there is much of a correlation between CPU benchmark and latency..
12:20 PM lcnc-relay: <skunkworks8841@discord> rs: thank goodness.. the machine went from handy capped to awesome..
12:22 PM lcnc-relay: <skunkworks8841@discord> It did have linear and circular interpolation.. but it was limited to 9.9999" radius. And I have no clue how it did it. It was a bit facetted..
12:22 PM lcnc-relay: <skunkworks8841@discord> No tool table.
12:23 PM lcnc-relay: <skunkworks8841@discord> But we ran it with the old control for years until we got a handle on Linuxcnc
12:36 PM xxcoder: LOL https://www.youtube.com/watch?v=4vWCXlqLK6g this shows power of 3d printer machine well. no company would create marble pick up vacuum attachment.
12:36 PM xxcoder: its short video
12:43 PM lcnc-relay: <huursabg@discord> how realiable is the backlash compensation on linuxcnc? is it better than the one in mach3
12:45 PM lcnc-relay: <skunkworks8841@discord> when the soldering went a little too good
12:45 PM lcnc-relay: <skunkworks8841@discord> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/czWZVgKmwmCGFvghxEorSitn/PXL_20241128_183615642.jpg
12:46 PM lcnc-relay: <JT> Let the cooking begin
12:59 PM lcnc-relay: <JT> https://jauriarts.org/_matrix/media/v3/download/matrix.org/WKbftvluBzcXOFPGzgQnbJvx/20241128_125118_4991097512052388658.jpg
01:05 PM _unreal_: hurrsab backlash options are fine. its really a question of how repeatable is the machine your using when changing directions.
01:33 PM rdtsc_away is now known as rdtsc
01:35 PM rdtsc: Re xx Marble overloards: nice. SW: looking kinda corroded; was that new or old? JT: same boat; trying to keep the mashed potatoes from boiling over
01:35 PM rdtsc is now known as rdtsc_away
01:36 PM rdtsc_away is now known as rdtsc
01:36 PM rdtsc: see what do you did there SW; please tell me you used rosin-cored solder on that?
01:37 PM rdtsc is now known as rdtsc_away
01:38 PM rdtsc_away is now known as rdtsc
01:39 PM rdtsc: for electrical connections, always use rosin-cored solder as acid-core will dissolve copper over time. Might be fine for pipe and 6ga, but in the long-term rosin-core is better on everything else
01:40 PM rdtsc is now known as rdtsc_away
01:51 PM rdtsc_away is now known as rdtsc
02:00 PM jpa-: hurrsab: backlash compensation is pretty poor substitute for having the backlash mechanically fixed; it only works well for single axis operations, if you do interpolated circles and similar, there will be visible artefacts
02:14 PM lcnc-relay: <captainhindsight_.@discord> skunkworks8841@discord I would probably keep the old controls just for show and have a PC behind it all. Maybe even add some blinkenlights from the 60's for dramatic effect.

02:18 PM xxcoder: would love to recreate the ultimate computer lol
02:18 PM xxcoder: love the 1960s effects
02:43 PM lcnc-relay: <vibram@discord> Hello, this is certainly a dummy question for you but I don't understand why 18,20,22,24,26 don't have the same description as they are working the same way according to the phrase below?
02:43 PM lcnc-relay: <vibram@discord> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/zBONDDYfeZkSJftWjpZZwwhu/rn_image_picker_lib_temp_a304e072-2b79-4ea8-ae3c-64f4dfd7a034.jpg
02:51 PM lcnc-relay: <captainhindsight_.@discord> Paolo Mantegazza of the RTAI project has died https://www.freelists.org/archive/rtai/11-2024
02:51 PM lcnc-relay: <captainhindsight_.@discord> https://www.freelists.org/post/rtai/Rtai-Future-of-RTAI he was 80

03:38 PM lcnc-relay: <skunkworks8841@discord> rdtsc: this is leadless solder - same as what you use for drinking water... (with 95 flux)
05:23 PM rdtsc: "95" likely being HoHS flux - still perhaps a good idea to clean that with LT (preferred) and/or IPA imo. Always best idea to get through 100% of the flux and know exactly what the solder looks like.
05:24 PM rdtsc: just because RoHS tends to be brittle
05:26 PM rdtsc: haven't seen any shorts due to RoHS flux (always a concerm), but have seen many crusty RoHS solder connections harboring cracked connections
05:27 PM rdtsc: large surface areas of copper are the exception; RoHS is typically used on a single pad and the flux entirely covers it.
05:29 PM rdtsc: SW, if "silver solder", the temps are even higher, with greater risk of brittle joints
05:30 PM lcnc-relay: <skunkworks8841@discord> this is just for a hydraulic return line... Nothing major
05:30 PM rdtsc: oh I thought this was for a copper buss bar
05:30 PM lcnc-relay: <skunkworks8841@discord> nope.. 🙂
05:30 PM lcnc-relay: <skunkworks8841@discord> I just stole from the copperp buss for my bracket.
05:32 PM rdtsc: hydraulic? use TIG + silicon bronze ;)
05:32 PM lcnc-relay: <skunkworks8841@discord> tig.. That would be nice.
05:32 PM lcnc-relay: <skunkworks8841@discord> Something I don't have yet
05:33 PM lcnc-relay: <skunkworks8841@discord> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/cQNlmtuEBUniSTnAqppyiFJo/PXL_20241128_232456829.jpg
05:33 PM lcnc-relay: <skunkworks8841@discord> it really soldered nice.. Time will tell if it lasts..
05:34 PM rdtsc: loops really nice; Ahp AlphaTiG 203xi, can personally recommend
05:34 PM rdtsc: https://ahpwelds.com/products/alphatig-203i
05:34 PM rdtsc: just need to add one bottle ot 100% argon
05:35 PM lcnc-relay: <skunkworks8841@discord> it will happen.. I just haven't pulled the trigger yet
05:35 PM lcnc-relay: <skunkworks8841@discord> pun intended
05:37 PM rdtsc: Used mine to fill in a 1/2" slot in a SS valve slide... mounted it to a piece of aluminium (an imcompatible metal), fed in ER309L filler, and patched the hole easily)
05:38 PM rdtsc: With all the stuff you work on, get a 203xl
05:38 PM rdtsc: then you can post videos about it :)
05:39 PM rdtsc: please not on holidays though... spend those with the fam
05:39 PM rdtsc: speaking of, grandkids are up, bbl
05:40 PM rdtsc is now known as rdtsc_away
05:49 PM lcnc-relay: <skunkworks8841@discord> Lol.. thanks. I am cooking tomorrow.
05:56 PM lcnc-relay: <xxcoder@discord> happy thankgiving all

06:01 PM Unterhaus_ is now known as Unterhausen
06:01 PM Unterhausen: I got a free turkey from FB. Having it tomorrow though
06:02 PM Unterhausen: I'm not a big fan of turkey, but we finally got an oven, so I felt compelled
06:22 PM rdtsc_away is now known as rdtsc
06:22 PM rdtsc is now known as rdtsc_away
07:12 PM lcnc-relay: <captainhindsight_.@discord> was up at 5 to go shopping, started cooking by 9 and by 3 we were all too tired to eat
07:14 PM xxcoder: doh
07:14 PM xxcoder: im cooking eggs right now. got this easy to cook eggs thingy to do it
07:16 PM lcnc-relay: <captainhindsight_.@discord> thanks for reminding me .... was going to make deviled eggs
07:17 PM lcnc-relay: <captainhindsight_.@discord> we only made about 3/4 of what we planned on cooking today
07:22 PM Tom_L: start a day ahead with things you can and it's not as bad
07:27 PM lcnc-relay: <captainhindsight_.@discord> that was the plan by yesterday turned into no sleep, an ER visit and designated driver
07:27 PM lcnc-relay: <captainhindsight_.@discord> by/but
07:28 PM lcnc-relay: <captainhindsight_.@discord> my holiday started yesterday at 6:30am
07:29 PM lcnc-relay: <captainhindsight_.@discord> I didn't make it to bed until 5pm
07:29 PM Tom_L: ate around 12:30 and i've had enough for lunch and dinner
07:30 PM Tom_L: hope you're doin ok
07:30 PM lcnc-relay: <captainhindsight_.@discord> i was just the driver
07:30 PM Tom_L: ok
07:30 PM Tom_L: been there a few times
07:32 PM lcnc-relay: <captainhindsight_.@discord> tomorrow is easy, just slow roasting BBback ribs
07:33 PM lcnc-relay: <captainhindsight_.@discord> going to be cold this weekend, I had outdoor project plans but not anymore
07:34 PM Tom_L: 26f overnite here
07:34 PM Tom_L: 46 for the high
07:34 PM xxcoder: whew eggs was really yummy
07:35 PM Tom_L: no outdoor plans here
07:35 PM xxcoder: and it was really ez to cook, didnt need to boil large amount of water for it.
07:36 PM lcnc-relay: <captainhindsight_.@discord> rdtsc: those Chinese welders are easily hacked for custom features
07:38 PM lcnc-relay: <captainhindsight_.@discord> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/iBCaPanJNboFELMZnpYZvrOy/wsme200-01.jpg

07:39 PM Tom_L: quite a pile of mosfets? there
07:40 PM lcnc-relay: <captainhindsight_.@discord> only mid 20's f for highs this weekend here
07:40 PM lcnc-relay: <captainhindsight_.@discord> yeah paralleled for more Amps
07:40 PM Tom_L: i wonder how they can rate them so high with small leads
07:41 PM lcnc-relay: <captainhindsight_.@discord> https://www.ebay.com/itm/173277563415 spare parts
07:41 PM lcnc-relay: <captainhindsight_.@discord> https://www.ebay.com/itm/173277563415 spare parts
07:43 PM lcnc-relay: <captainhindsight_.@discord> https://www.ebay.com/itm/173277562225 on the backside of the PCB
07:43 PM lcnc-relay: <captainhindsight_.@discord> https://www.ebay.com/itm/173277562225 on the backside of the PCB
07:43 PM lcnc-relay: <captainhindsight_.@discord> since they would need 8oz copper or more for the layer
07:43 PM Tom_L: saw that on the first pics
07:44 PM lcnc-relay: <captainhindsight_.@discord> https://www.vishay.com/docs/91215/irfp260.pdf
07:46 PM Tom_L: surprising the lead doesn't become a fuse
07:46 PM rdtsc_away is now known as rdtsc
07:47 PM rdtsc: IRFP260: "ease of paralelling" heheheh
07:47 PM Tom_L: rdtsc, you see jt got flex installing with apt now?
07:47 PM Tom_L: not on the rpi yet
07:47 PM rdtsc: no, haven't seen it yet
07:48 PM Tom_L: https://www.gnipsel.com/linuxcnc/flexgui/install.html
07:48 PM Tom_L: the rpi looks for versions different
07:48 PM Tom_L: i think
07:48 PM rdtsc: capn, all I can say is the Ahp 203xi has worked great (at 240VAC input) for everything I've thrown at it. which admittedly, isn't much
07:50 PM lcnc-relay: <captainhindsight_.@discord> I remember going shopping for welders for the first time in China, they laughed when I was guessing the prices, they were all <$300usd
07:50 PM rdtsc: but setting the footpedal for a range of10A to 110A, can tack a sheet of aluminium to 1/4in steel all no prob (haven't tried larger)
07:51 PM lcnc-relay: <captainhindsight_.@discord> we have giant old millers at work
07:51 PM rdtsc: I'll be keeping a close eye on it it though
07:52 PM rdtsc: millers and old lincolns = cadillacs of welding
07:52 PM Tom_L: i have a small miller
07:53 PM Tom_L: 175 iirc
07:53 PM lcnc-relay: <captainhindsight_.@discord> yours is an inverter vs the old iron core transformer
07:53 PM Tom_L: yeah
07:53 PM lcnc-relay: <onceloved.cn@discord> Does anyone know how to use inmux? http://linuxcnc.org/docs/stable/html/man/man9/hostmot2.9.html#inm%20and%20inmux
07:53 PM Tom_L: i remember those
07:54 PM rdtsc: I'm no welding snob... much better at soldering'
07:55 PM Tom_L: i don't do much of either anymore
07:55 PM lcnc-relay: <captainhindsight_.@discord> had to weld some 0.5" plate the other day, the current was at only ~25%, was almost filling too fast
07:56 PM rdtsc: Here is some great infofor tig welding: https://www.youtube.com/@PacificArcTigWelding
07:56 PM Tom_L: do they even use stick much anymore?
07:56 PM lcnc-relay: <captainhindsight_.@discord> I'd rather not, it's boring much like machining
07:57 PM lcnc-relay: <captainhindsight_.@discord> the fun for me is only in the design of the machine
07:57 PM rdtsc: I bothered for the argon tank, so would prefer not to use stick... could in a pinch I suppose
07:57 PM rdtsc: 203xi supports everything
07:58 PM lcnc-relay: <captainhindsight_.@discord> yeah, I had to use stick a few weeks ago since they were out of wire
07:59 PM lcnc-relay: <captainhindsight_.@discord> well it was "hidden" vs out, the union auto workers are very territorial, but it takes about 6 of them to change a lightbulb
08:01 PM lcnc-relay: <captainhindsight_.@discord> onceloved.cn@discord: are you looking for examples?
08:02 PM lcnc-relay: <onceloved.cn@discord> captainhindsight_.@discord: Yes
08:02 PM rdtsc: Had use of a 1980's 200A MIG welder for years... never liked it much; TIG is much more finnicky but capable
08:03 PM rdtsc: even more of an art-form, if such is possible
08:03 PM lcnc-relay: <captainhindsight_.@discord> onceloved.cn@discord https://forum.linuxcnc.org/49-basic-configuration/50350-help-to-understand-net-command
08:03 PM lcnc-relay: <captainhindsight_.@discord> onceloved.cn@discord https://forum.linuxcnc.org/49-basic-configuration/50350-help-to-understand-net-command
08:05 PM lcnc-relay: <onceloved.cn@discord> Thanks but that's not what I want
08:06 PM rdtsc: inmux, in what capacity, onceloved? inmux is a modern part of many mesa boards
08:07 PM rdtsc: tom, now if only we could get JT to compile his own aarch64 builds :)
08:07 PM lcnc-relay: <captainhindsight_.@discord> onceloved.cn@discord https://forum.linuxcnc.org/39-pncconf/47881-index-homing-mesa-7i96s?start=30#301807

08:08 PM lcnc-relay: <captainhindsight_.@discord> onceloved.cn@discord search around the forums
08:09 PM lcnc-relay: <onceloved.cn@discord> captainhindsight_.@discord: Thank you I will take a look
08:09 PM lcnc-relay: <onceloved.cn@discord> rdtsc: It’s rv901
08:10 PM rdtsc: https://forum.linuxcnc.org/27-driver-boards/47730-new-project-litehm2-a-hostmot2-port-to-linsn-rv901t
08:12 PM rdtsc: But so far, with only a few hours of use, the Ahp 203xi is performing beauifully. Only complaint is this revision doesn't ever turn fans off. Other than that, zero complaints.
08:13 PM rdtsc: For my first TIG machine
08:13 PM rdtsc: and with only filling in a 1/2" hole in a SS plate and various aluminum patches/welds
08:14 PM rdtsc: did get filler for SS, aluminum, steel, etc.
08:17 PM rdtsc: even phosphor bronze wire (from the local home-improvement) for doing any type of brazing-equivalent
08:18 PM rdtsc: did one project, decades ago, where I filled in milled slots using brazing then turned on a lathe... would be easier with phosphor-bronze
08:21 PM rdtsc: of course everything would have been easier and far more accurate if I'd been using LCNC back then
08:24 PM rdtsc is now known as rdtsc_away
08:26 PM lcnc-relay: <captainhindsight_.@discord> I used lots of silicone bronze for sheet metal
08:37 PM Tom_L: rdtsc_away, i have a script for it so it's pretty painless
08:38 PM Tom_L: builds them both for me
08:38 PM Tom_L: and puts the arch64 one on my git repo
09:11 PM lcnc-relay: <big_kevin420@discord> did some shitty docs for my axis thing, now that i need to use it more, i need to fix more shit with it
09:11 PM lcnc-relay: <big_kevin420@discord> https://github.com/cakeslob/regularmac_800
09:11 PM lcnc-relay: <big_kevin420@discord> https://github.com/cakeslob/regularmac_800
09:12 PM lcnc-relay: <big_kevin420@discord> phil really flew under the radar with his plasmac gui. i wish he did more stuff with regular axis
09:15 PM lcnc-relay: <big_kevin420@discord> trying to do a small/big screen in the same gui is really painful. i wish all my screens were huge 1024*768 screens
09:21 PM lcnc-relay: <big_kevin420@discord> and now the bait is set
09:21 PM lcnc-relay: <big_kevin420@discord> i just need to wait for an ambitious python coder to come along and opensource fix all my mess that I dont know how to do
