04:04 AM -!- #linuxcnc mode set to +v by ChanServ
04:11 AM rmu: seems the forum has a troll problem
04:41 AM JT-Cave: morning
04:42 AM JT-Cave: rmu, where?
04:42 AM Tom_L: morning
04:43 AM JT-Cave: failed to get linuxcnc 2.10 to install on debian 13 as well
04:44 AM Tom_L: maybe somebody will add 2.9 support for the boards
04:52 AM JT-Cave: that would be nice, it's not much to cherry pick that back to 2.9
04:52 AM Tom_L: did you try 2.10 on debian 11?
04:53 AM Tom_L: likely get the same result
04:58 AM JT-Cave: no
05:02 AM rmu: JT-Cave: https://forum.linuxcnc.org/51-ot-posts/50072-how-to-send-a-process-or-thread-to-kernel-space-via-lxrt?start=10
05:02 AM travis_farmer: Morning :-)
05:06 AM travis_farmer: wow, just... wow. that user deserves a beat...... lesson ;-) but seriously, wow.
05:20 AM JT-Cave: gone
05:20 AM rmu: that guy obviously is a kind of idiot that doesn't stomach that nobody cares about his problems running windows audio plugins on wine in linuxcnc kernels and doesn't understand that you can't send processes "to kernel space", i.e. his initial question is not only off-topic but completely idiotic
05:20 AM rmu: thanks
05:23 AM JT-Cave: what got him banned was his off color comments
05:25 AM rmu: JT-Cave: yes of course. i will contact you again should anything like that appear again on the forum
05:28 AM -!- #linuxcnc mode set to +v by ChanServ
06:43 AM JT-Cave: rooster just crowed
06:59 AM JT-Cave: I think I'll just copy the 7i95t from 2.10 to 2.9 and build emc here
07:09 AM JT-Cave: mom and daughter deer are eating breakfast
07:18 AM JT-Cave: building 2.9 with 7i92T and 7i95T support
07:30 AM JT-Cave: still getting opengl errors... fi going to ride at Wolf creek
09:40 AM Unterhaus_ is now known as Unterhausen
09:40 AM Unterhausen: weird, the interwebs aren't working for me
09:41 AM Unterhausen: usually, IRC is the first to go out
09:42 AM travis_farmer: everything works for me, and i am in a hurricane... ;-)
10:11 AM travis_farmer: is there a HAL component to log a specific value to a file, given an event? what i want to do is log the current program line, when an E-stop is triggered.
10:18 AM travis_farmer: but i wonder if motion.program-line will change to 0 when E-stop is triggered...
10:56 AM roycroft: well, i did it
10:57 AM roycroft: today we start preparing ballots to mail for our upcoming election
10:57 AM roycroft: i got the voter roll book printed out a bit after midnight, and the mailing labels printed by 2am
10:57 AM * roycroft has been working on this for weeks
10:58 AM CaptHindsight: didn't you just have an election?
10:59 AM roycroft: we had a recall election in february
10:59 AM roycroft: but our annual election is in october
10:59 AM CaptHindsight: vote early, vote often
10:59 AM roycroft: hopefully we'll prevent the latter
11:00 AM roycroft: in the recall election, though, several ballots were returned by non-members
11:00 AM roycroft: they apparently intercepted (or were given) the ballot sent to someone else in their household
11:00 AM roycroft: and when they returned it they didn't even bother to forge the voter's name and signature
11:01 AM CaptHindsight: familial identity impersonation
11:02 AM CaptHindsight: rmu: were the forums slow 6-8 hours ago as well?
11:06 AM CaptHindsight: https://motocompacto.honda.com/ cycle disguised as a suitcase
11:12 AM Unterhausen: is there such a thing as a boring head that fits on an arbor with a 1 1/4" thread?
11:13 AM rmu: CaptHindsight: didn't notice anything but I wasn't very active
11:15 AM pere: I flagged several ru.po translations for review, because of newline discrepencies caused build failures. Someone who understand the language should have a look at fix the strings. <URL: https://hosted.weblate.org/projects/linuxcnc/-/ru/ > now got 15 unfinished strings.
12:40 PM Unterhausen: interwebs are really slow today. It's like they want to force me to go log into my modem and see what's up
01:03 PM Unterhaus_ is now known as Unterhausen
01:53 PM JT-Cave: https://github.com/LinuxCNC/linuxcnc/issues/2642
01:53 PM JT-Cave: not that anyone cares that linuxcnc is broken now
01:54 PM JT-Cave: the issue I reported yesterday is gone now...
01:54 PM JT-Cave: WTF
01:57 PM Tom_L: did somebody fix it>
01:57 PM Tom_L: ?
02:11 PM JT-Shop: it == recent 2.9/2.10 no
02:11 PM JT-Shop: Leo just released a new video
02:22 PM pcw---home: JT-Shop Did you notice the M4 issue in the forum? You might consider adding the reverse spindle speed setting in you INI file generation
02:22 PM JT-Shop: no, but I'll look thanks
02:23 PM pcw---home: Even if the default value gets fixed, it probably good to have it there as an example
02:25 PM JT-Shop: when did they add MAX_REVERSE_VELOCITY
02:32 PM Contract_Pilot is now known as Rhine_Labs
02:33 PM pcw---home: Not sure and the docs say it defaults to MAX_VELOCITY but it does not seem to so M4 doesn't work unless its defined
02:33 PM JT-Shop: ok, thanks for the tip I'll add that in the morning
02:34 PM pcw---home: (also it doesn't show up in the ini hal pins)
02:34 PM JT-Shop: kinda frustrated trying to test the 7i95T with 2.10
02:34 PM pcw---home: in fact no spindle setting do
02:34 PM JT-Shop: even with reading the ini function?
02:35 PM pcw---home: Not with halcmd
02:36 PM pcw---home: like somethings missing, maybe after the multiple spindle changes
02:38 PM JT-Shop: that would be my guess too
03:12 PM travis_farmer: just added it to my INI, in case i ever upgrade... i didn't even seem to have a SPINDLE_0 section...
03:17 PM JT-Shop: do you have a spindle controlled by hal
03:17 PM travis_farmer: yes
03:18 PM JT-Shop: do you have a spindle section
03:18 PM travis_farmer: in hal, yes
03:18 PM JT-Shop: in the ini
03:19 PM travis_farmer: i didn't before. it was regulated by the values in the DISPLAY section
03:26 PM travis_farmer: my ini was originaly made by PNCconf back in Dec 12 2020 :-) i have dragged it allong as i have upgraded LinuxCNC, and seems to work still :-)
03:26 PM travis_farmer: though i had to do the whole joint upgrade
03:31 PM JT-Shop: it prob works in both display and spindle 0 "for now"
03:31 PM travis_farmer: yes, "for now" :-S
03:33 PM travis_farmer: yeah, i am running 2.9 Pre 1 from the debian repo, so that may be why it works, "for now"
03:37 PM travis_farmer: hmmm, power just flickered... :-(
03:37 PM JT-Cave: hmm the 7i95T is now working in 2.9... maybe because it shows up as 7i95?
03:46 PM pcw---home: the 7I95t always worked but pre 2.9.something it was not discovered so the pinout list when LinuxCNC starts was not correct
03:47 PM pcw---home: just like the 7I92T in linuxCNC its hal names are all just the base name (but its full name must be different so mesaflash knows what it is)
04:01 PM JT-Shop: thanks
04:03 PM * JT-Shop has a challenging tree to cut up... a lot of branches are pretty high up as it could not roll as it fell
06:25 PM Tom_L: MAX_REVERSE_VELOCITY appears first in the 2.9 docs
06:25 PM Tom_L: not in 2.8
08:09 PM pcw---home: Yes, and M4 fails if MAX_REVERSE_VELOCITY not set (to a non-zero number) in 2.9 or 2.10
08:17 PM Tom_L: defaults are not set?
08:20 PM Tom_L: This setting will default to MAX_VELOCITY if omitted. acording to the docs
08:34 PM Tom_L: i haven't encountered that yet... still running 2.8.4 on the mill
08:37 PM pcw---home: No, the default appears to be zero
08:37 PM solarwind: if I cut a gear out of annealed 4140, will its dimensions change significantly after quenching and tempering?
08:38 PM solarwind: pcw---home random question: what is the resolution of frequency synthesis on the mesa cards?
08:38 PM solarwind: for step/dir pulse generation
08:38 PM pcw---home: For the stepgen?
08:38 PM solarwind: yes
08:38 PM Tom_L: zero would indicate ccw is not allowed
08:38 PM pcw---home: 32 bits
08:39 PM solarwind: what is the mechanism of frequency synthesis?
08:39 PM pcw---home: DDS
08:39 PM solarwind: excellent
08:39 PM solarwind: what chip are you using?
08:39 PM pcw---home: any FPGA
08:39 PM solarwind: ah ok
08:40 PM solarwind: so it's just a 32 bit register counter?
08:41 PM solarwind: at whatever frequency the FPGA is clocked at?
08:41 PM pcw---home: There is a prescaler but its not actually been used. I think with the commom 100 MHz base clock you get something like 1/40 Hz resolution
08:41 PM pcw---home: so not important at the nominal 1 KHz servo thread rate
08:43 PM pcw---home: It's actually a 48 bit accumulator
08:43 PM solarwind: Yeah I was just wondering for my stepper experiments. I got steppers to spin at 8,000 RPM with a signal from a dedicated signal generation
08:43 PM solarwind: they are very sensitive to jumps in speed when ramping up
08:44 PM pcw---home: The position feedback is 16.16 so you get 16 bit of full steps and 16 bits of fractional steps for feedback
08:46 PM pcw---home: so the phase errors are typically much smaller than an (external) step
10:36 PM Beef: Howdy, I've heard this is the place to come for development topics for LinuxCNC over Discord, but I haven't used IRC since like ... the days where AIM was popular. I also guess I need to change my nickname as someone is using it here ...
10:37 PM Tom_L: this is the main linuxcnc channel but there is also one for developers
10:39 PM Tom_L: and for the moment the matrix/discord bridge is broken
10:41 PM Beef is now known as IAmTheRealBeef
10:43 PM Tom_L: wrong time of day for much activity on either channel
10:46 PM IAmTheRealBeef: No worries, I am hardly in a place that I am ready to ask questions - but I figure I'll get more active in the coming months anyway
10:46 PM IAmTheRealBeef: Using the webclient, I assume that there is no message history kept while I'm offline. Is that correct?
10:48 PM IAmTheRealBeef: ah, that's how it works. Thank you
10:48 PM Tom_L: or download hexchat and use that
10:49 PM Tom_L: also
10:49 PM IAmTheRealBeef: "Since XChat is open source, it’s perfectly legal." lol
10:52 PM XXCoder: its by nice bot here, so yeah sometimes bot leaves so log isnt showing
10:54 PM XXCoder: I use hexchat
10:55 PM Beef: I'm on it now as well, gives me that '90s vibe all over again but it's also probably easier than the web browser
10:58 PM XXCoder: irc will always work really
10:58 PM XXCoder: if discord company goes under its all gone
11:00 PM Beef: Yes absolutely - I've done a fair number of writeups and project logs and so on and have downloaded and been revising them bit-by-bit to bring from discord over to my own website as well so they're not lost in the next couple of years
11:01 PM Beef: Recommend something like Obsidian.md or another similar program (whatever you find suits you) for organizing the 938 projects many of you guys likely have - I know I have too many to keep in my head
