01:33 AM Deejay: moin
02:00 AM travis_farmer: Morning :-)
04:22 AM Tom_L: morning
04:53 AM JT-Cave: morning
04:53 AM JT-Cave: 55°F
06:35 AM Tom_L: 66F
06:41 AM JT-Cave: rooster just crowed
06:43 AM travis_farmer: Federal IRS tax refund just hit my account :-D
06:56 AM JT-Cave: nice emc 2.10 has lot's of issues and won't run
07:20 AM JT-Cave: some kind of opengl error here
07:21 AM travis_farmer: glad i didn't upgrade, really ;-)
07:21 AM JT-Cave: I had to upgrade to test the 7i95T board
07:33 AM travis_farmer: there, i officially have Vcarve Pro now! :-D now to learn how to use it...
08:41 AM Tom_L: yard done hopefully for the last time
08:59 AM Tom_L: JT-Cave, what about the 7i92t? does it run on 2.8--2.9 or does it have the same issue as the 7i95t
09:59 AM travis_farmer: so, i made up a quick 10" square plaque with a deer on it, and a little scenery (from Vcarve clipart)... setup sheet says estimated time for both roughing and finish passes is 4 hours, 3 minutes! i had anticipated a lot of mill time, but 4 hours for a 10" square project? all i can say is, wow, i need stable power for this machine so it doesn't fail in a storm....
10:00 AM rmu: are you finishing with a 1mm ball endmill?
10:01 AM travis_farmer: 1/8in
10:28 AM travis_farmer: OMFG! i updated to use the actual endmills i have from Amana... now total time is 12:42:24 !!! this gets better and better, LMAO! :-D
10:41 AM travis_farmer: what do people do in the event of a power failure? my eventual plan is to have the spindle VFD on a magnetic switch, and have the machine power and computer power on UPS backups (sepperate ones). then have the AC power fault trigger an E-stop.
10:42 AM JT-Cave: Tom_L, the 7i92t works on 2.9 for sure
10:42 AM Tom_L: start the 13hr thing all over :)
10:42 AM Tom_L: JT-Cave, wonder why the change on the 7i95t
10:42 AM JT-Cave: new
10:43 AM Tom_L: same fpga chips though right?
10:43 AM Tom_L: he must have updated something in the hostmot2 driver
10:44 AM JT-Cave: yup and yup
10:44 AM JT-Cave: gotta run and clean chicken shit
10:44 AM travis_farmer: seriously, Tom_L? waste all that time and money??? sounds discouraging:-(
10:44 AM Tom_L: it happens in shops too
10:44 AM Tom_L: scrap parts and go on
10:44 AM travis_farmer: :-(
10:45 AM Tom_L: if you're lucky you can salvage the part
10:46 AM travis_farmer: Hmmm, sounds like i need to setup backup plans for material...
10:46 AM Tom_L: if you're good you can note the approximate line you were on and run from line on a z move
10:46 AM Tom_L: but
10:46 AM Tom_L: if you do that be sure to edit the line above it with a M3
10:46 AM Tom_L: and start there
10:46 AM Tom_L: i've done that
10:47 AM rmu: re-post the file in question and deactivate all finished operations
10:47 AM rmu: and pray that your machine homes repeatable
10:47 AM Tom_L: rmu, in his case it's likely going to be a single cutter
10:48 AM Tom_L: for vcarve stuff
10:48 AM travis_farmer: two cutters
10:48 AM travis_farmer: 1/4 ball, and 1/8 ball
10:48 AM travis_farmer: rough and finish
10:49 AM Tom_L: is that 13 hrs running at max?
10:49 AM Tom_L: we've had a few parts that ran for a week
10:49 AM travis_farmer: not at max
10:50 AM Tom_L: when we were making prototype parts that didn't have forgings yet cut from a solid billet of titanium
10:50 AM Tom_L: landing gear etc
10:50 AM travis_farmer: gotta run and get lunch... be back in a bit
10:51 AM rmu: 7i95t has different FPGA chip AFAIK, something like this https://www.digikey.com/en/products/detail/efinix-inc/T20F256C4/10654496
10:53 AM Tom_L: ahh
10:54 AM Tom_L: i thought he was using the same efinix on all the new boards
10:55 AM rmu: i meant different chip than 7i95 of course ;)
10:55 AM rmu: sorry
10:58 AM -!- #linuxcnc mode set to +v by ChanServ
11:03 AM Tom_L: oh, yeah i knew he switched from xilinx
11:24 AM JT-Cave: someone needs to cherry pick the 7i95t support back to 2.9... 2.10 is just too broken
11:26 AM JT-Cave: https://github.com/LinuxCNC/linuxcnc/commit/223837403938b43f0233e1216e65dfeb2b7cf3e4
11:37 AM skunkworks: Lol - I have been running a windows 11 vm here at work as my main workstation.. I guess I only allocated 4gb of ram..
11:38 AM skunkworks: I would not have known - other than my chrome tabs seemed to R3scapind!
11:38 AM skunkworks: have to re-load
11:41 AM roycroft: does windows even boot with only 4gb of ram these days? :)
11:54 AM rigid: no one needs a nicely colored a-axis, but it doesn't hurt either: https://www.amazon.com/dp/B0C581H2B3/
11:54 AM skunkworks: I guess - been running it for atleast a year.. or more
11:55 AM rigid: roycroft: i guess "slipstreaming" is what kids do these days?
11:55 AM rigid: or whats it called
11:56 AM roycroft: i don't know what that is
11:56 AM rigid: some process to remove all the bloat & tracking and gives you a somewhat lightweight windows install
11:56 AM roycroft: i just know that i need to allocat 8gb of ram to a windows vm to get it to do anything useful
11:57 AM rigid: my tax software runs in 2GB VM
11:57 AM rigid: not exactly fast. and it's probably not really demanding.
11:58 AM rigid: but for win11 i'll probably need 4GB aswell
11:59 AM skunkworks: This was a windows 7 vm -> windows 10 upgrage -> windows 11
12:01 PM rigid: i'll do only fresh minimal install. last time I used some debloating script someone recommended. That helped a lot.
12:02 PM rigid: then I keep a snapshot of the clean install and just copy that for other stuff when I need a fresh install
12:04 PM skunkworks: The only reason I checked the memory is chrome seemed to shut down a lot of tabs - so I would notice them re-loading..
12:05 PM skunkworks: and that didn't happen on my laptop or at home. So - I guess that makes sense now
12:10 PM skunkworks: now it has 16gb :)
12:11 PM skunkworks: I don't know how real hardware works - but windows seems to run just fine on 4gb ram in qemu...
12:32 PM roycroft: i can install windows with 4gb of ram
12:32 PM roycroft: it's just not useful for anything i do
12:32 PM roycroft: but i should qualify that by saying that almost everything i do with windows is either cad software or bloaty java crap (primarily from cisco)
12:33 PM roycroft: and java, that "portable" language, tends to foster apps that only run on a particular java version on a particular os
01:10 PM skunkworks: This is mostly used for database applications and admin stuff
01:11 PM skunkworks: nothing super heavy. Still - honesty suprised it ran as well as it did.
01:20 PM travis_farmer: well that was exciting... just finished an online meeting... :-|
01:23 PM travis_farmer: hey, roycroft: i got my copy of Vcarve Pro this morning :-)
01:46 PM roycroft: nice
01:47 PM roycroft: have you upgraded to 11.55 yet?
01:47 PM travis_farmer: 11.552 :-)
01:47 PM roycroft: yeah, that's the minor release that is current
01:48 PM roycroft: when i got cut2d, the downloaded version was not current and i had to update to 11.55 right away
01:48 PM roycroft: then, a few days later, 11.552 came out
01:48 PM roycroft: so their downloader isn't necessarily current
01:48 PM travis_farmer: lol, figures ;-)
01:49 PM travis_farmer: yeah, but the update was included, so that's fine
01:50 PM travis_farmer: i even found the Amana tool database, so i can just pull the mills i have in my kit :-)
01:53 PM travis_farmer: pretty good kit, when you get your cnc router built: https://www.amanatool.com/ams-131-8-pc-signmaking-starter-cnc-router-bit-collection-ii-1-4-inch-shank.html
01:55 PM roycroft: nice
01:56 PM roycroft: the tool database doesn't do me any good right now, but when i get my cnc router built it will be a great help
02:18 PM * roycroft needs to work on the dxf to svg conversion issue still, and hopes to have time to invest in that soon
02:19 PM roycroft: sw has a heap of dfx export options, and it may take me a while to find the magic combination that lets cut2d do the conversions exactly as i need
02:25 PM travis_farmer: dang IRC kicked me... getting annoying...
05:49 PM memleak: Has anyone seen this before? https://dpaste.com/EYGTUNKJL
05:49 PM memleak: I was just testing LinuxCNC out again on Gentoo and that came up, LinuxCNC won't start
06:00 PM memleak: axis_9axis works just fine. I guess the sims aren't tested very much since you all have real machines :)
07:16 PM solarwind: Damn, the lucas "extra heavy duty" polyurea grease is insanely hard to wash off even with soap
07:16 PM solarwind: "excellent water resistance" is an understatement
07:17 PM solarwind: the red n tacky lithium complex on the other hand washes off with soap and water and scrubbing
07:18 PM memleak: isn't the red n tacky for marine use?
07:18 PM solarwind: other way around
07:18 PM solarwind: red n tacky for general purpose
07:18 PM memleak: ah
07:19 PM solarwind: they have a specific "marine" grease though, I think calcium sulfonate thickener
07:20 PM solarwind: I use the red n tacky for most things like high speed gears in air tools, etc. Never had an issue. I have a case of 20 cartridges.
07:20 PM solarwind: I'm going to buy a grease "sprayer" so I can coat the inside of machine tools to protect them from rust
07:21 PM solarwind: I use the extra heavy duty polyura one on the outdoor forklifts, it definitely does its job
07:53 PM CaptHindsight: be careful about junk getting stuck in the grease after application
07:53 PM CaptHindsight: it becomes a chip magnet
09:21 PM memleak: solarwind, what distro are you on? I just updated the 4.19 and 5.4 RTAI kernels but I can't build them due to something about relocations and read-only.
09:21 PM memleak: From my memory, that's because my version of Binutils is too new basically for the current source.
09:22 PM memleak: older toolchains should work fine. I know you said you use RTAI so that's why I updated the patches. I have 5.4.256 and 4.19.294
09:23 PM memleak: I pushed them to my for-next branch because I haven't even boot tested either: https://github.com/NTULINUX/RTAI/tree/for-next
09:36 PM memleak: Hmm maybe I can cherry-pick some of these... i.e. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/arch/x86/boot/compressed/head_64.S?h=v5.10.194&id=a2c4fc4d4e2c40b07534094810d915c7354d84a7
09:36 PM memleak: brb
09:50 PM memleak: nope, too much code differences. trying LLD instead of BFD
10:06 PM memleak: ld.lld: error: init sections too big!
10:06 PM memleak: Whelp, I'm SOL.
10:07 PM memleak: I'll try building on debian at some point but 5.4 might just be too old now.
