08:11 AM perry_j1987: morning
08:21 AM pere: hi
09:31 AM Tom_L: so flip it over and then mirror the scan
09:43 AM GTKplusplus6432[: I can't find anything about this anywhere.
09:43 AM GTKplusplus6432[: Is there some setting to tell gmocappy to use g54 zero as the center of my a axis for display purposes?
09:43 AM GTKplusplus6432[: The gcode works fine, but the preview is centered around the machine zero point, which makes the displayed radius completely wrong, and of course the tool position doesn't match the gcode preview, so it's very hard to understand what is going on
09:43 AM GTKplusplus6432[: it's a minor display issue, I guess, but makes checking my code much harder than it should be
09:45 AM GTKplusplus6432[: I found a 2018 thread that says it's not possible, so I guess if nothing changed I'd need to fix that myself
10:02 AM sparafucile: help
10:02 AM sparafucile: i'm ok sorry,GTK see use of '!' in https://linuxcnc.org/docs/devel/html/config/ini-config.html
10:03 AM sparafucile: in section for [DISPLAY]GEOMETRY
10:07 AM GTKplusplus6432[: Ah, ! to respect the offsets
10:08 AM GTKplusplus6432[: thank you, I read over that a couple times but completely skipped over that line
10:08 AM sparafucile: Use of ! is available in master branch (not 2.8)
10:08 AM GTKplusplus6432[: Ah
10:08 AM GTKplusplus6432[: Guess it's going to wait a bit then
10:08 AM GTKplusplus6432[: I'm on 2.8 with a project to finish first
10:09 AM GTKplusplus6432[: just have a couple more 4 axis operations to do and at this point I'm fairly sure my fusion setup is fine
10:09 AM GTKplusplus6432[: and they are just indexing moves to begin with
12:08 PM _unreal_: Interesting? my weather report app says VERY HIGH UV
12:14 PM perry_j1987: it looks like there's a slight rock in this mini lathe saddle
12:14 PM _unreal_: does it roll?
12:15 PM perry_j1987: lol
12:25 PM perry_j1987: really makes me want to just build a new one with linear rails lol
12:25 PM * RoboticsNut1189[ uploaded an image: (1832KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/RZTpJyIFiLlYFquKZDQNyuyP/IMG_7013.jpg >
12:25 PM RoboticsNut1189[: assembly of to section of new jointer
12:26 PM perry_j1987: if I made a new plate that moved all the gang tools back so the tips were closer to the center of the saddle that would greatly reduce the effect of the slight rocking though right?
12:27 PM * RoboticsNut1189[ uploaded an image: (6825KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/KeLRtJaNqpfZQzPFLfqeQkcR/278EAAA8-CAF9-459B-B08B-B46C0A3856D1.jpg >
12:42 PM solarwind: https://www.youtube.com/watch?v=WGqHZ1PY2E0
12:42 PM solarwind: That's a mighty fine end mill
12:43 PM solarwind: Is that actually a horizontal spindle, or is it just the camera?
12:46 PM Rab: Looks like a Pocket NC, at least for some of the operations. https://www.pentamachine.com/pocket-nc
12:47 PM Rab: With turning on some kind of mini lathe.
12:48 PM solarwind: I'm more interested in the gear machining
12:48 PM solarwind: I'd love to be able to do that. I think it should be doable with a 4th axis on my 3 axis CNC machine
12:49 PM acer: looks like that video is using the mini 3d mill pro what ever its called
12:49 PM acer: the mini 5 axis mill
12:49 PM solarwind: Rab is right, it's the pocket nc
12:49 PM solarwind: I see the logo at 2:34
12:51 PM solarwind: I hear a lot of chatter, but makes sense for a desktop mill
12:51 PM solarwind: I think my 4,000kg LeBlond Makino should be able to handle a little gear just fine :D
12:56 PM solarwind: Damn, my 10" rotary table weighs more than the entire Pocket NC machine
12:59 PM RoboticsNut1189[: jointer will be used to mill the 8-1/4 maple for the robotic workbench:
12:59 PM * RoboticsNut1189[ uploaded an image: (787KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/qorJinbXtMjZKykoOtcCNomH/38CA7510-183F-47B9-ACD4-075CC663AA3D.jpg >
01:12 PM CaptHindsight[m]: solarwind: sorry about your PocketNC, can you return it?
01:23 PM mrec: solarwind: involute gears?
01:24 PM mrec: I'm doing quite a bit gear milling, I'm a bit stuck now on spindle synchronization I don't want to rewire my controller
01:24 PM mrec: so I'm waiting for some HW so I can connect the encoder via network/udp
01:35 PM -!- #linuxcnc mode set to +v by ChanServ
02:24 PM XXCoder: https://youtu.be/hMLDiEGru18
02:24 PM XXCoder: interesting
02:26 PM RoboticsNut1189[: That looks pretty neat.
02:26 PM XXCoder: purely drill and grinder
02:31 PM JT-Shop: my other brother john build a vise in shop class with a welder, saw and a file
02:31 PM XXCoder: nice
02:32 PM RoboticsNut1189[: What percentage of people on this channel are on IRC vs. Discord?
02:32 PM XXCoder: 147 on irc
02:32 PM XXCoder: some dupicates like myself. im on both irc and discord
02:34 PM XXCoder: only part I wonder is how well vise faces is 90 degrees from inside base, and is vase faces parallel? so on
03:20 PM JT-Shop2: prob good enough to hold something while you use a hacksaw
03:26 PM roguish[m]: 104.5 right now, and going up.
03:35 PM * JT-Shop2 is not going to mention the temperature here
03:37 PM XXCoder: jt drills too as he demos with various extrusions
03:37 PM XXCoder: weird. single day 86f on next sat
03:43 PM roycroft: there is only one reference face on a vise
03:43 PM roycroft: jaw
03:47 PM justache- is now known as justache
04:11 PM JT-MachineShop: sometimes there are more than one...
04:15 PM Tom_L: 89F
04:23 PM Tom_L: jaws can be 2 faced just like ppl
04:23 PM Tom_L: :)
04:31 PM JT-MachineShop: https://www.kurtworkholding.com/wp-content/uploads/2020/01/Kurt-Workholding-HDL4J_B-600x600.jpg
04:35 PM Tom_L: you have some of those?
04:36 PM XXCoder: only saw 2 of that kind in shop I worked at. pretty cool
04:44 PM JT-Shop2: no Kurt vises here and no doubles
04:49 PM roguish[m]: 107.2 now
04:52 PM Tom_L: roguish[m], that looks more like a radio station :)
04:52 PM pcw--home: not when it gets above 108
04:53 PM roguish[m]: pcw--home: probably be there soon. definitely tomorrow. you're probably similar PW
04:54 PM pcw--home: Its around 100 here
04:54 PM Tom_L: 119
04:54 PM Tom_L: °F in death valley
04:54 PM Tom_L: 124 predicted for tomorrow
04:55 PM pcw--home: We are less than 2 miles from the bay so this is really unusual
04:55 PM Tom_L: no breeze?
04:55 PM pcw--home: warm breeze
04:55 PM Tom_L: we've had one of the hottest summers here on record i think
04:56 PM pcw--home: air conditioning is relatively rare here
04:56 PM Tom_L: not _the_ hottest but right up there
04:58 PM pcw--home: we have still been getting a cool pacific breeze in the evenings so that helps
05:02 PM JT-MachineShop: I have 3 like this https://www.micro-machine-shop.com/parlec_2.jpg and one glacern
05:05 PM ZincBoy[CAON][m]: How do you find the parlac vs the glacern? I have a couple of the glacern vice and have no complaints so far.
05:14 PM Tom_L: i've got a shars 4" on my little one
05:14 PM JT-Shop2: the glacern was the last one I got, they seem to be the same
05:14 PM Tom_L: my bud offered me a free 8" kurt but i told him it wouldn't fit on the mill
05:14 PM JT-Shop2: I have a glacern next to a parlac in the vmc
05:15 PM JT-Shop2: a 4" kurt would be nice
05:15 PM Tom_L: yes
05:15 PM Tom_L: does kurt make a 4"?
05:15 PM Tom_L: oh i think i looked at the time and they're more than the 6"
05:15 PM Tom_L: 6" are alot more in demand
05:16 PM ZincBoy[CAON][m]: Good to know. I didn't expect much difference but I need to get a 3rd vice soon.
05:17 PM * JT-Shop2 thinks before gluing up wood he better make a 3-d model
05:17 PM Tom_L: https://www.shars.com/4-440v-cnc-milling-machine-vise-0-0004-1
05:17 PM Tom_L: no stock
06:59 PM ZincBoy[CAON][m]: https://www.glacern.com/gsv_440
06:59 PM ZincBoy[CAON][m]: Almost double the price of the shars one though.
06:59 PM roguish[m]: well, looks like we peaked at 111.9, that'd' be 44.388 for roycroft.........
07:00 PM XXCoder: rog that sucks
07:01 PM roguish[m]: going inland about 20 miles adds another 10
07:46 PM * roycroft is far from the only person who uses sensible temperature units
07:47 PM roycroft: i am almost ready to permanantly install the counter top on my new cabinets
07:47 PM roycroft: if this coat of wax suffices i'll be doing it in a few minutes, otherwise later tonight or tomorrow
07:47 PM * roycroft will be glad to be done with that project
08:57 PM Jeratan[m]: i'm seeing internet wisdom repeatedly says that you specifically need an older PC with a parallel port. is there any reason I can't use the plethora of $10 parallel port PCIe cards?
09:00 PM Rab: Jeratan[m], no. Some work great, but others might not.
09:03 PM Rab: Jeratan[m], specifically, CaptHindsight[m] reported a good experience with this card: https://www.vantecusa.com/products_detail.php?p_id=122&p_name=2-Port+Parallel+PCIe+Host+Card&pc_id=12&pc_name=Add-on+I%2FO&pt_id=4&pt_name=Add-on+Cards
09:05 PM Rab: I've had good luck with the super-cheap CH382-based cards, which have a parport and up to two serial ports.
09:11 PM Rab: I'm having trouble finding the exact cards I bought, because it was a few years ago and they're totally generic. This is cosmetically very similar, and claims to have a WCH382L chip: https://www.ebay.com/itm/254673774088
09:12 PM Rab: I've run two at once in LinuxCNC, one for step/dir signals and one for limit switches, with no issues.
09:14 PM Rab: Some don't have the serial ports populated, or just one, and you can add those just by soldering on a 2x5 header and a MAX3243C if you're curious like I was.
09:18 PM Rab: I meant to add my cards to the wiki, but I'm afraid it would be misleading to claim compatibility since there seem to be so many variants. If you have access to Amazon Prime, might want to exploit those free returns if it doesn't work out. https://www.amazon.com/dp/B08MY86DWB
09:24 PM CaptHindsight[m]: Rab: have you hqd good luck wit the wch382?
09:24 PM Rab: CaptHindsight[m], indeed.
09:24 PM CaptHindsight[m]: hqd/had
09:24 PM CaptHindsight[m]: that if fcking weird
09:24 PM CaptHindsight[m]: all of mine don't work with 2.9
09:25 PM CaptHindsight[m]: that is on my list to fix
09:25 PM CaptHindsight[m]: Rab: which kernel and which LCNC are you using them with?
09:25 PM CaptHindsight[m]: they used to work for me
09:25 PM Rab: Hmmmmmmm, I'm using 2.9.0~pre0
09:26 PM CaptHindsight[m]: and yes https://www.vantecusa.com/products_detail.php?p_id=122&p_name=2-Port+Parallel+PCIe+Host+Card&pc_id=12&pc_name=Add-on+I%2FO&pt_id=4&pt_name=Add-on+Cards is what I am currently using for tests
09:26 PM CaptHindsight[m]: Rab: huh!
09:26 PM CaptHindsight[m]: ok which kernel?
09:26 PM Rab: And I was using an old RTAI kernel, but latency went crazy at some point and I tried mainline rt and it worked better than rtai ever did.
09:27 PM Rab: So before it was 4.14.174-rtai-amd64 and now it's 5.10.0-17-rt-amd64.
09:27 PM CaptHindsight[m]: oh so you are using an RTAI kernel with wch382 and they work fine?
09:28 PM Rab: I was, but not anymore.
09:28 PM CaptHindsight[m]: ok I have lcnc 2.8 with RTAI running on a system next to me with the 2 LPt port vantec card
09:28 PM Rab: I never tried to test their performance, I just put my (fairly conservative) machine config into stepconf and went with it.
09:28 PM CaptHindsight[m]: i will try the wch382 and see if they magically work now
09:29 PM CaptHindsight[m]: right now i am trying to debug why the spindle encoder does work with axis in 2.8 with RTAI 4.x
09:29 PM CaptHindsight[m]: does NOT work
09:30 PM CaptHindsight[m]: doesn't work at all with axis in 2.8 with RTAI 4.x and throws a signal 8 core dump with LCNC 2.9 and preempt_rt
09:30 PM Rab: 01:00.0 Serial controller: Device 1c00:3250 (rev 10)
09:31 PM CaptHindsight[m]: somebody broke a bunch of stuff between 2.9 and 2.9 and RTAI with LPT ports
09:31 PM CaptHindsight[m]: between 2.8 and 2.9 and preempt_rt
09:32 PM CaptHindsight[m]: good to know, more crap to fix :(
09:32 PM Jeratan[m]: are serial ports usable as inputs?
09:32 PM Rab: Is there a newer 2.9 than 2.9.0~pre0?
09:32 PM CaptHindsight[m]: Jeratan: nope
09:33 PM Tom_L: Rab, i don't think so
09:33 PM CaptHindsight[m]: Rab: well doesn't 2.9 change near daily?
09:33 PM Tom_L: the version hasn't anyway
09:33 PM Tom_L: but being master, what CaptHindsight[m] said.
09:34 PM Tom_L: it's the 'sid' of linuxcnc
09:34 PM CaptHindsight[m]: I am going to try a wch382 with LCNC 2.8 and RTAI in a minute. The wch382's definitely don't work with preempt_rt and LCNC 2.9
09:35 PM CaptHindsight[m]: Rab: can you post you ini and hal?
09:35 PM CaptHindsight[m]: you/your
09:36 PM CaptHindsight[m]: if it's handy, otherwise I'll just run a simple stepconf version
09:36 PM CaptHindsight[m]: the wch382 issue is weird
09:38 PM Rab: CaptHindsight[m], sure! http://reboots.g-cipher.net/linuxcnc/
09:39 PM CaptHindsight[m]: Rab: thank you!, what is weird that Peter and Jon Elson could not get the wch382's to work after i used them all the time
09:40 PM CaptHindsight[m]: now I can't get them to run :(
09:40 PM Rab: CaptHindsight[m], they may not work without my USB peripherals connected if you're going to try to run them.
09:40 PM CaptHindsight[m]: Rab: why is that?
09:41 PM Rab: I dunno, it just crashes out.
09:41 PM CaptHindsight[m]: Rab: so far the hal and ini look pretty straighfroward
09:42 PM Rab: ./custom.hal:5: waitpid failed hal_input hal_input
09:42 PM Rab: ./custom.hal:5: hal_input exited without becoming ready
09:42 PM CaptHindsight[m]: Jeratan: sorry, what are you trying to find??
09:42 PM Jeratan[m]: so the CH382 and WCH382L seem to be about the same price ($30 +p&p) for me, there's some HP parallel port cards on ebay for $6, are they worth trying?
09:42 PM Rab: Jeratan[m], if you're willing to gamble the money.
09:42 PM CaptHindsight[m]: Jeratan: I dug into all this about a week ago. The HP's use a good LPT chipset but they were mostly PCI vs PCIe. What do you have available?
09:43 PM Jeratan[m]: i guess i'll roll the dice and report the finding
09:43 PM CaptHindsight[m]: CH382 and WCH382L, what is the difference?
09:43 PM CaptHindsight[m]: just Chinese spelling? :)
09:44 PM Rab: CaptHindsight[m], I should specify that I had not touched the machine in a long time, and when I did, LinuxCNC would no longer start with RTAI. There was some kind of real time error I don't recall. So I switched to RT, and it worked fine (which it hadn't in the past).
09:44 PM * Jeratan[m] uploaded an image: (229KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/SDNdeDdbaAKrXYfOyBOffcmX/unknown.png >
09:44 PM Jeratan[m]: exhibit A
09:44 PM Rab: I don't think that was related to the parport hardware, I couldn't even get into stepconf.
09:44 PM CaptHindsight[m]: Rab: thanks, I'll ping you in the next day or two with either an answer or more questions :)
09:44 PM * Jeratan[m] uploaded an image: (171KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/DULIYzHhJixJYgkNCnIMvrnO/unknown.png >
09:44 PM Jeratan[m]: exhibit B (claims WCH CH351Q chip)
09:44 PM Rab: I believe CH382 and WCH382L are the same part.
09:45 PM Rab: CaptHindsight[m], good luck!
09:45 PM CaptHindsight[m]: http://www.wch-ic.com/products/CH382.html
09:45 PM Rab: I just found this in sources.list: deb http://linuxcnc.org/ buster base 2.8-rt
09:45 PM Jeratan[m]: do the image links come through alright on IRC?
09:46 PM CaptHindsight[m]: http://www.wch-ic.com/downloads/file/320.html?time=2022-09-06%2010:45:30&code=vs5BR7wsXEgCuSU1vqVZe9Nxmfyckrsmm4LVEBR9
09:46 PM Rab: ...Which is kinda disturbing, since I'm on bullseye and 2.9-pre. I may be running some frankenstein system which isn't reproducable.
09:47 PM CaptHindsight[m]: Rab: still good to know, it might help narrow down the problem
09:47 PM CaptHindsight[m]: I have about 10 test systems here, from Buster and 2.8 to Sid and 2.9
09:48 PM CaptHindsight[m]: we even have LCNC 2.9 running on Gnetoo with prempt_rt and RTAI
09:48 PM CaptHindsight[m]: Jeratan: they come through fine
09:48 PM CaptHindsight[m]: Jeratan: whay do you need PCI or PCIE LPT?
09:49 PM CaptHindsight[m]: you caught me with them all out on the bench right now doing tests
09:49 PM Jeratan[m]: i have one PCI and 4 PCIE slots
09:50 PM CaptHindsight[m]: Jeratan: are you in the USA?
09:50 PM Jeratan[m]: no, AU
09:50 PM Jeratan[m]: lucky me :)
09:50 PM CaptHindsight[m]: ah let me check
09:51 PM Tom_L: CaptHindsight[m], are you testing standalone use or pp -> mesa use?
09:51 PM Tom_L: would be nice if you posted your findings somewhere
09:52 PM CaptHindsight[m]: Tom_L: stand alone, no Mesa LPT are available
09:52 PM CaptHindsight[m]: in the process of doing so
09:52 PM CaptHindsight[m]: but I'm fixing a bunch of turds in LCNC
09:53 PM Tom_L: they seem to be making quite a few changes to it
09:53 PM CaptHindsight[m]: Jeratan: for PCI, wch351 and mcs9805 (moschip)
09:55 PM CaptHindsight[m]: Jeratan: for PCIe, moschip mcs9900, asix ax99100
09:56 PM pcw--home: Some 7I90s are still available (but re-spun cards will concentrate on Ethernet, then PCIE)
09:56 PM Jeratan[m]: CaptainHindsight (@_discord_702231000050040894:jauriarts.org) thanks!
09:56 PM CaptHindsight[m]: and whatever Jon Elson has posted on his website for PCI or PCIe http://pico-systems.com/osc2.5/catalog/product_info.php?products_id=30&osCsid=2st94jl73q6likvi5hmhtmqad7
09:57 PM Jeratan[m]: i'm yet to check if the mobo causes any funky latency problems
09:57 PM Jeratan[m]: no ddr3 ram around atm
09:57 PM CaptHindsight[m]: Jeratan: do that first
09:57 PM CaptHindsight[m]: doesn't take any new hardware to test latency, just bios options
09:57 PM CaptHindsight[m]: pcw--home: thanks , noted!
09:58 PM CaptHindsight[m]: Tom_L: I usually forum post for newly tested LPT cards
10:00 PM CaptHindsight[m]: pcw--home: did you see that Rob has the wch382's working? after you and Jon and I tried to get them going with preempt_rt
10:00 PM CaptHindsight[m]: I'll try them with RTAI in a few minutes
10:01 PM CaptHindsight[m]: Jeratan: option A that you posted got coved by the pic of option B, can you report?
10:01 PM CaptHindsight[m]: repost
10:02 PM Jeratan[m]: there's no info in the description, unfortunately
10:02 PM Jeratan[m]: just a picture of the card
10:02 PM * Jeratan[m] uploaded an image: (229KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/pRxlEFmbRXeihxxkvKaywcBt/unknown.png >
10:02 PM pcw--home: ISTR that some needed the hardware specific driver to enable the card
10:03 PM CaptHindsight[m]: Jeratan: option B definitely works with preempt_rt and LCNC 2.9
10:03 PM Jeratan[m]: awesome
10:03 PM Jeratan[m]: i'll check that the mobo works and start with that one
10:03 PM CaptHindsight[m]: pcw--home: I never did when they worked and Rab doesn't appear to be either
10:05 PM CaptHindsight[m]: pcw--home: there was an issue a few years ago with some versions of the wch382 since it may be configured for 1LPT or 1lpt and 1serial or 2 serial and no LPT
10:05 PM CaptHindsight[m]: but that PCI ID issues were back ported 3 or more years ago
10:06 PM pcw--home: Right at the time it needed specific driver to set up the card to look like a normal parallel port
10:07 PM pcw--home: (that may be built in now)
10:07 PM pcw--home: it was many years ago when I tested them
10:08 PM CaptHindsight[m]: pcw--home: you and Jon posted that was the issues but it was not my experience
10:08 PM CaptHindsight[m]: we never loaded any special drivers here
10:08 PM CaptHindsight[m]: ok so maybe we can solve this weirdness once and for all :)
10:08 PM pcw--home: might have been already built into Linux
10:09 PM CaptHindsight[m]: the kernel issue was just PCI ID's for the standard LPT kernel driver
10:09 PM CaptHindsight[m]: ok I'll plug a wch382 into this RTAI machine in a few minutes and see what it does
10:10 PM CaptHindsight[m]: brb
10:18 PM andypugh_ is now known as andypugh
10:19 PM snakedLX is now known as snaked
10:19 PM pcw--home: Jon an I would have tested it for a working EPP mode, that may be a difference
10:20 PM CaptHindsight[m]: nothing out of it here, same as I recall with you guys
10:20 PM CaptHindsight[m]: yet Rab has it working
10:21 PM pcw--home: I would have tested it with DOS and low level access that expects a standard LPT register map
10:22 PM Rab: I gotta go to bed, but if you want any more into I can look tomorrow.
10:22 PM pcw--home: But I think its been 10 years...
10:23 PM CaptHindsight[m]: Rab: thanks, good night
10:23 PM CaptHindsight[m]: I'm working on the spindle encoder issues with LPT, was planning on fixing wch382 later this week anyway
10:24 PM pcw--home: I notice the WCH382 data sheet is pretty useless
10:24 PM CaptHindsight[m]: loadrt hal_parport cfg="0 out"
10:24 PM CaptHindsight[m]: Rab's kernel found it!
10:25 PM CaptHindsight[m]: there is a full one
10:25 PM CaptHindsight[m]: hold on
10:26 PM CaptHindsight[m]: http://www.wch-ic.com/downloads/file/140.html?time=2022-09-06%2011:25:04&code=F9OgfLXI9oH8lRGqgAg6u8dd8uTc6oBOfyLXLZWz shows the PCI id strapping
10:27 PM CaptHindsight[m]: http://www.wch-ic.com/downloads/file/320.html?time=2022-09-06%2010:45:30&code=vs5BR7wsXEgCuSU1vqVZe9Nxmfyckrsmm4LVEBR9 has more register info
10:27 PM CaptHindsight[m]: and I think there is a third with all the driver info
10:30 PM pcw--home: Looks pretty standard, seems it should just work
10:31 PM pcw--home: do cards ever have the EEPROM installed?
10:32 PM CaptHindsight[m]: yeah i have a feeling the way the kernel reads the pci id's is wrong
10:32 PM CaptHindsight[m]: I mean the pci id's in the list that kernel uses is broken
10:33 PM CaptHindsight[m]: pcw--home: nope, none that I have ever seen have the EEPROM
10:33 PM CaptHindsight[m]: and 5-6 years ago the cards just work with RTAI and LCNC
10:34 PM CaptHindsight[m]: anyway, that is for later in the week
10:34 PM pcw--home: the EEPROM makes no sense unless a large OEM wanted their own branded cards
10:35 PM CaptHindsight[m]: stepconf doesn't let you enter PCI id's for LPT cards that the kernel doesn't find
10:35 PM CaptHindsight[m]: Tommylight noticed this as well on the forums
10:36 PM CaptHindsight[m]: you have to LSPCI and then manually edit your hal file
10:36 PM CaptHindsight[m]: but this doesn't work for the ch382's
10:39 PM CaptHindsight[m]: now I am trying to fix why LCNC 2.8 can't read spindle encoders on the LPT pins 10 and 11 and throws a signal 8 and core dump on 2.9
10:39 PM CaptHindsight[m]: the signals show up in halscope
10:39 PM CaptHindsight[m]: in 2.8
10:39 PM CaptHindsight[m]: but not in the GUI for spindle RPM
10:40 PM CaptHindsight[m]: they show up in 2.9 but error out with signal 8
10:40 PM CaptHindsight[m]: i think the LPT got ignored by the devs and nobody noticed until now
10:42 PM pcw--home: Bug in the encoder comp?
10:43 PM CaptHindsight[m]: skunkworks tried my encoder config on 2.8 and it worked for him, but errored like mine with 2.9
10:44 PM CaptHindsight[m]: I am on 2.8 with RTAI and it don't work :)
10:44 PM CaptHindsight[m]: so not sure what skunkworks and I have different
10:45 PM CaptHindsight[m]: why i hate software :)
10:46 PM pcw--home: looks like there were some encoder changes in 2019, 2021
10:47 PM CaptHindsight[m]: pcw--home: heh, other than you and JT, who touches Mesa code? :)
10:49 PM pcw--home: I don't think anyone changes driver code but me currently, more people poke at mesaflash
10:49 PM pcw--home: Andy has done a large amount of driver code (especially with sserial)
10:49 PM CaptHindsight[m]: probably why it works so well
10:51 PM pcw--home: the encoder comp thing is pretty mysterious, though the segv is probably traceable under Preempt-RT
10:51 PM CaptHindsight[m]: going to test 2.8 with preempt_rt to see it's an RTAI vs preempt_rt issue
10:52 PM pcw--home: wonder if the WCH382 thing has to do with its class code
10:53 PM CaptHindsight[m]: will try tomorrow when Skunkworks can tell me if he actually has the GUI showing spindle speeds or just that it did not signal 8 like 2.9 does
10:53 PM CaptHindsight[m]: ntulinux/memleak knows the kernels pretty well
10:54 PM CaptHindsight[m]: he will be back tomorrow
10:54 PM CaptHindsight[m]: he was going to trace the git changes back to when the encoder issue shows up and test the wch382
10:54 PM pcw--home: Good luck
10:54 PM pcw--home: bbl
10:55 PM CaptHindsight[m]: git bisect and similar
10:55 PM CaptHindsight[m]: see you
10:59 PM CaptHindsight[m]: more wierdness, the ch382 inputs are getting encoder signals since I can see them in halscope
10:59 PM CaptHindsight[m]: however the outputs aren't stepping
11:04 PM * roycroft is trying to figure out what part of the labor day holiday tradition involves massive consumer spending
11:05 PM roycroft: the "labor day sale" spam is still rolling in, and has been pretty steady for days now
11:05 PM XXCoder: everything is spend spend spend now
11:05 PM XXCoder: if there was "stay home, rest and dont buy anything day" there woiuld be ads to spend money then
11:05 PM XXCoder: *holiday
11:06 PM roycroft: i did buy some stuff today
11:06 PM roycroft: the day after thanksgiving is the day that i stay home and spend no money at all
11:06 PM roycroft: it's my tradition :)
11:06 PM XXCoder: :) last time I went out specifically for black friday sales was when I bought very good leather coat
11:07 PM XXCoder: I still have it now and still wearing it
11:07 PM XXCoder: and its over 20 years old
11:07 PM XXCoder: $220 of 1990s money bought for just $30 lol
11:07 PM roycroft: i got my countertop installed today
11:07 PM XXCoder: 30 / 20 years = $1.50 a year cost so far
11:08 PM roycroft: my handplanes are back in the shop, finally
11:08 PM XXCoder: nice!
11:08 PM roycroft: yeah, and i installed the shelf for my stereo as well
11:08 PM XXCoder: $418 usd today money lol
11:09 PM XXCoder: $54 for today money ($30)
11:10 PM * roycroft has a leather jacke that's about that old as well
11:10 PM roycroft: the fit is a bit tighter than it used to be
11:10 PM roycroft: i didn't know leather shrinks over time
11:15 PM XXCoder: interesting
11:15 PM XXCoder: well mines still been great
11:15 PM roycroft: anyway, the cabinet is done, and i'm finishing up making some speaker shelves that will be done in a day or two
11:15 PM roycroft: elections work is going to consume all my time for a week or so after that, but then i'll be back to my cnc router design
11:17 PM roycroft: i'm going to miss my target date to get it done, but i'll still get it done before too much longer
11:21 PM XXCoder: cool :)
