10:18 AM lcnc-relay: <skunkworks8841@> Nice!
11:10 AM lcnc-relay: <unterhausen@> I finally figured out why it has to spin to pick up a tool. Does it ever cross-thread the nut?
11:25 AM lcnc-relay: <skunkworks8841@> I bet they are pretty hardened..
11:27 AM lcnc-relay: <skunkworks8841@> thoughts? I have some lathe tooling that I could just cut a bxa dovetail into it?
12:13 PM lcnc-relay: <unterhausen@> I think I don't understand the question
12:14 PM pere: <URL: https://inv.nadeko.net/watch?v=RxBT-9mMqe8 > is quite nice. :)
12:14 PM lcnc-relay: <unterhausen@> Lots of people have made toolholders, but they are cheap on ebay
01:17 PM Tom_L: Unterhausen, you won't be doing any rigid tapping with those holders
01:18 PM Unterhausen: Tom_L which holders?
01:19 PM Unterhausen: I feel like the ebay bxa holders are plenty stout enough, but if you are talking about the collet nut driven toolchanger, maybe it wouldn't work
01:25 PM Tom_L: in the yt toolchange thing
03:54 PM lcnc-relay: <skunkworks8841@> unterhausen@ https://photos.app.goo.gl/dZnRtxFGHPnPJw7u8
03:56 PM lcnc-relay: <unterhausen@> lathe tooholders like to eat endmills. And I'm not sure you have enough contact area
04:10 PM JT-Shop: also you need some way to set the height
04:10 PM JT-Shop: https://www.corvetteforum.com/forums/c3-tech-performance/4903080-82-steering-overhaul-2.html#post1608612010
04:25 PM Tom_L: cool
04:25 PM Tom_L: why all the 'bleeps' in the one post?
04:27 PM JT-Shop: bleeps?
04:27 PM Tom_L: Cleaned and inspected the worm gear assembly and everything was fine so I put new ***** in. You feed the ***** in
04:28 PM JT-Shop: it's your browser
04:28 PM Tom_L: hah
04:28 PM JT-Shop: Cleaned and inspected the worm gear assembly and everything was fine so I put new balls in. You feed the balls in from the end holes (with grease) until they come out of the middle holes.
04:28 PM xxcoder: bowlerized
04:29 PM Tom_L: ff
04:29 PM xxcoder: unneeded censoring to make things sound dirtier than it really is
04:30 PM Tom_L: silly
04:31 PM Bleepshop: xxcoder: Bowdlerized.
04:31 PM xxcoder: yeah
04:31 PM lcnc-relay: <mikemader@> So, I am trying to run my CNC for the first time in a couple of months. It was working without issue. Now, I am getting the attached error message. I was working on zeroing the bit when this happened, and the gcode file had not been opened yet, so no real load on it. I am currently on 2.9.3. https://1drv.ms/i/s!AsMg06LZj85xgotYC7frVRXpQM9rTg?e=vWGfmy
04:31 PM lcnc-relay: <mikemader@> Sorry for the image link, Discord isn't letting me upload an image for some reason.
04:32 PM xxcoder: its fine, its disabled due to weird stuff with bridge handling images in discord
04:32 PM lcnc-relay: <mikemader@> Gotcha
04:33 PM JT-Shop: use https://pasteboard.co/ to share an image
04:33 PM lcnc-relay: <mikemader@> https://pasteboard.co/lGMOu50IiLsx.png
04:34 PM Tom_L: i wonder where you turn that off in FF
04:34 PM xxcoder: not sure if thats ff or not. I dont get that
04:34 PM JT-Shop: run the latency-histogram --nobase
04:35 PM JT-Shop: looks like you have a latency problem
04:35 PM Tom_L: only other thing on it is ublock origin
04:35 PM JT-Shop: I use that too
04:35 PM Tom_L: i turned that off temporarily and didn't change anything
04:35 PM JT-Shop: ublock would not censor anything
04:36 PM xxcoder: might be forum itself
04:36 PM xxcoder: ublock here too
04:36 PM Tom_L: FF 115.20.0
04:37 PM JT-Shop: 128.3.1esr (64-bit)
04:37 PM JT-Shop: linux
04:37 PM Tom_L: win 32bit
04:37 PM xxcoder: 135 on minty fresh linux (lmde 6)
04:37 PM Tom_L: i've noticed a few minor differences between win and linux ff
04:39 PM Tom_L: anybody know of a program to import bookmarks from 2 browsers without duplicates?
04:42 PM lcnc-relay: <mikemader@> This is what I get when I run latency-histogram --nobase:
04:42 PM lcnc-relay: <mikemader@> waitpid failed /usr/bin/rtapi_app threads
04:42 PM lcnc-relay: /usr/bin/rtapi_app exited without becoming ready
04:42 PM lcnc-relay: insmod for threads failed, returned -1
04:42 PM lcnc-relay: while executing
04:42 PM lcnc-relay: ... long message truncated: https://jauriarts.org/_heisenbridge/media/jauriarts.org/RHMFJPxadTCfYdcixfguwGeS/qJeW3lmZFnU (20 lines)
04:46 PM Tom_L: did the same thing on my linux ff
04:48 PM lcnc-relay: <mikemader@> That said, when looking at top, there is an "rtapi_app" that is taking 10% of the CPU
04:50 PM JT-Shop: did you shut down linuxcnc?
04:50 PM JT-Shop: you can't run them both at the same time
04:51 PM lcnc-relay: <mikemader@> Yes, it is shut down
04:54 PM lcnc-relay: <mikemader@> I rebooted, now it is working
04:55 PM lcnc-relay: <mikemader@> I have glxgears running as well
05:02 PM lcnc-relay: <mikemader@> https://pasteboard.co/kowkCJHwYpdx.png
05:02 PM JT-Shop: that's not bad for 7i96
05:06 PM lcnc-relay: <mikemader@> So, any thoughts as to why I am getting that error message?
05:08 PM JT-Shop: maybe something caused some latency that made the watchdog bite, run your configuration for a while and see if you get bit again
05:08 PM lcnc-relay: <mikemader@> Okay, will try again
05:29 PM lcnc-relay: <mikemader@> So, I got the job done that I set out to do
05:29 PM lcnc-relay: <mikemader@> I think I may know what happened.
05:29 PM JT-Shop: what's that?
05:30 PM lcnc-relay: <mikemader@> The little mini PC has on board WIFI that barely reaches the nearest AP, and a USB WIFI that works very well.
05:30 PM lcnc-relay: <mikemader@> It supposed to default to the USB wifi, but doesn't always.
05:31 PM lcnc-relay: <mikemader@> I found it was using the on board one, and it was trying to do something that normally would have quickly been done, but instead was chewing on the CPU.
05:31 PM JT-Shop: odd
05:32 PM lcnc-relay: <mikemader@> Very much so.
05:32 PM JT-Shop: at least you got your job done
05:32 PM lcnc-relay: <mikemader@> I think I may just pop the cover off, and pull out the M2 Wifi board.
05:32 PM lcnc-relay: <mikemader@> Yeah, it was only supposed to be a 5 minute job too! lol
05:33 PM JT-Shop: yeah I know how that goes
05:33 PM lcnc-relay: <mikemader@> Thank you for your help!
05:33 PM JT-Shop: I restoring an 82 C3 and everything takes 10 times as long as you thing
05:34 PM JT-Shop: think
05:34 PM JT-Shop: your welcome, glad I could help
05:43 PM lcnc-relay: <mikemader@> That said, the router on the CNC sounds like it is about ready to be replaced. It didn't sound good while running. 😦
05:44 PM JT-Shop: ouch
05:48 PM Unterhausen: since most of the clough42 fan club is here, I found out he has a ripoff belt sander design
05:48 PM lcnc-relay: <mikemader@> I am hoping it was just a bit too cold for it
05:48 PM JT-Shop: I've seen people spend a fortune on replacing a router and never make anything
05:48 PM Unterhausen: sometimes I'm glad nobody watches my youtube channel so I'm not tempted to do such things
05:49 PM lcnc-relay: <mikemader@> It is a Bosch 1617 on it, so it won't be too expensive to replace.
05:50 PM lcnc-relay: <mikemader@> One of these days I need to get a spindle for it.
05:50 PM lcnc-relay: <skunkworks8841@> unterhausen@ yes - I would pick the ones that are soft. The kinemetal ones are very hard.
05:50 PM xxcoder: wonder how easy it would be to rebuild bosch
05:51 PM xxcoder: new bearings, new bushings if needed
05:51 PM lcnc-relay: <mikemader@> Probably not too terrible, the 1617 has been around forever
05:51 PM * JT-Shop calls it a day
05:52 PM lcnc-relay: <mikemader@> I think the one in my router table is nearing 20 years old, still runs great.
05:52 PM JT-Shop: better quality in the older ones
05:53 PM lcnc-relay: <mikemader@> True. I had a bosch sander I really liked that finally quit. Bought a new one of the same version, it had issues.
05:53 PM lcnc-relay: <mikemader@> I ended up buying a festool as a result, lol.
05:53 PM roycroft: clough 42's design is shite
05:53 PM JT-Shop: festool makes some good stuff
05:54 PM roycroft: he forgot to steal the best feature from jer schmidt - a drivetrain that moves independently to the table
05:54 PM lcnc-relay: <mikemader@> They do at that. You pay for the quality.... but it is quality.
05:54 PM roycroft: so now you have a sander with excellent extraction and that runs so smoothly you can use it all day
05:54 PM roycroft: which festool sander did you geti?
05:54 PM roycroft: get, rather
05:55 PM lcnc-relay: <mikemader@> And I was a former festool skeptic too, lol. Once I finally used the sander on a project and saw the difference in finish quality, I was a believer.
05:55 PM JT-Shop: I still have not explored the blue tooth issue with the extractor
05:56 PM lcnc-relay: <mikemader@> It is the ETS 125 REQ
05:56 PM roycroft: most festool skeptics have never used any festool kit :)
05:56 PM roycroft: aah, that was my first festool sander
05:56 PM roycroft: it now has the edge sanding attachment permanently installed
05:57 PM roycroft: not permanent as in it can't be removed - permanent as in i leave it installed and squared up all the time
05:57 PM lcnc-relay: <mikemader@> Nice. I think my next festool purchase will be the DTS 400 REQ
05:58 PM * roycroft has 7 festool sanders now, but not the dts 400 req
05:58 PM roycroft: and i think i'm done buying sanders
05:58 PM lcnc-relay: <mikemader@> LOL
05:58 PM roycroft: they are all different, and i use them all, most on a regular basis
05:59 PM Unterhausen: Clough stole his design from House Made. It's a very popular design
05:59 PM Unterhausen: I'm glad he didn't steal Jer's design, that would have annoyed a lot more
05:59 PM roycroft: i like jer schmidt's design much better
06:00 PM roycroft: clough's doesn't even rotate at all
06:00 PM roycroft: it's fixed position
06:00 PM roycroft: so i guess that independent movement thing is moot
06:01 PM lcnc-relay: <skunkworks8841@> I every once in a while want a fancy sander.. But my ancient 1 inch and wood working 6 inch work just fine.
06:01 PM roycroft: i bet you have enough scrap metal around to build one of jer schmidt'd grinders
06:01 PM lcnc-relay: <skunkworks8841@> the 1 inch is a delta rockwell
06:01 PM roycroft: and i'm sure you have a motor
06:02 PM roycroft: you would only need the wheels and perhaps a vfd
06:02 PM lcnc-relay: <skunkworks8841@> sure.. not on the priority list
06:02 PM lcnc-relay: <skunkworks8841@> have those in a drawer too
06:02 PM lcnc-relay: <skunkworks8841@> (vfd's not the wheels)
06:02 PM roycroft: but you have the monarch
06:02 PM roycroft: so you can easily make the wheels
06:03 PM lcnc-relay: <skunkworks8841@> sure. and a cnc to create the arc..
06:03 PM roycroft: i had a 1x36? (i'm pretty sure it was 36") before i built the 2x72
06:03 PM lcnc-relay: <skunkworks8841@> lol - what word am I looking for?
06:03 PM roycroft: night and day difference in performance
06:04 PM roycroft: it doesn't replace the 6x89 edge sander though
06:04 PM roycroft: i wish i had room for one of those in the shop - i really miss it
06:05 PM roycroft: maybe i'll get a smaller, vertical version
06:05 PM lcnc-relay: <skunkworks8841@> yah - that is on the second floor of the barn. It gets used off and on
06:05 PM roycroft: that was probably my favorite tool i ever sold
06:05 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/gPKbQE8fb8w23Htz8
06:06 PM roycroft: but the reality was that i did not have the room or it
06:06 PM roycroft: for

06:17 PM lcnc-relay: <pixiepaws01@> https://www.youtube.com/watch?v=imxnpvtXNv4 he is turning between centers and mentions that it lets him "sneak up" on the dimensions because it allows the metal to "relax". What does he mean by that?
06:19 PM lcnc-relay: <pixiepaws01@> You can't really sneak up on steel with carbide inserts, at least definitely not neutral/negative rake inserts with a land. You need a super sharp honed edge and a positive rake like on uncoated inserts for alumium if you want to take shallow depth of cut.
06:20 PM lcnc-relay: <pixiepaws01@> Any time I've tried to take less than the minimum recommended depth of cut, it leaves a poor finish and it's hard to hit the dimensions, so I have to aim for the finishing pass to take a pretty big depth of cut, even with finishing inserts.
06:20 PM lcnc-relay: <pixiepaws01@> I don't know how he's getting such a good surface finish with the insert he's using at such a shallow cut
06:20 PM -!- #linuxcnc mode set to +v by zirconium.libera.chat
06:21 PM lcnc-relay: <pixiepaws01@> Also he doesn't use a drive dog initially, hmmm
06:21 PM lcnc-relay: <skunkworks8841@> he is lucky.
06:22 PM lcnc-relay: <skunkworks8841@> I have gotten by without drive dogs..
06:22 PM lcnc-relay: <mikemader@> I fixed the WIFI issue so that it will now default to the better WIFI interface.

06:35 PM lcnc-relay: <ccatlett1984@> If my stepper drivers are labeled 1600 pulses/rev , and I know that the motors are 200 steps/rev, I should be putting a value of 8 for microsteps, correct?
06:36 PM lcnc-relay: <ccatlett1984@> just found the example in the docs, looks like that is correct.
06:56 PM lcnc-relay: <skunkworks8841@> ,,
09:20 PM BorgPipe is now known as NetPipe
09:24 PM memleak: finally published the gentoo image, installer works but only supports preempt_rt at the moment
09:25 PM memleak: (6.12 kernel)
09:25 PM memleak: https://github.com/NTULINUX/gentoo_backup/releases
09:25 PM memleak: i'll be working on the rtai image soon
09:30 PM memleak: instructions: https://openlunchbox.com/mw19/index.php/HOWTO:_Gentoo_for_LinuxCNC#Fetching_the_installer
09:37 PM lcnc-relay: <mikemader@> So, should my bosch router need replacing, this spindle & VFD I found isn't really much more in cost. Any gotchas with these? https://www.amazon.com/gp/product/B0CR326WH6/ref=ewc_pr_img_1?smid=A3A1CXRHIIBHYY&th=1 https://www.amazon.com/gp/product/B0B4MWGX99/ref=ewc_pr_img_2?smid=A3E9T3KQ1YPBBY&psc=1
09:37 PM lcnc-relay: <mikemader@> Will that VFD work with 7i96?
09:37 PM lcnc-relay: <mikemader@> +my
09:57 PM Tom_L: 7i96 or 7i96s?
09:57 PM Tom_L: S would give you analog out to the vfd
09:57 PM lcnc-relay: <mikemader@> 7i96, no S
09:57 PM Tom_L: you can always add a spinx board for that if you need to
09:58 PM Tom_L: for analog control
09:58 PM lcnc-relay: <mikemader@> I bought it before the chip shortage, lol
09:58 PM Tom_L: 0-10v
09:58 PM lcnc-relay: <mikemader@> Would the RS-485 be an option for speed control?
09:58 PM Tom_L: https://mesaus.com/product/spinx1a/
09:59 PM Tom_L: it could be yes
09:59 PM Tom_L: analog seems easier to me if the vfd supports it
10:06 PM lcnc-relay: <mikemader@> So, I am assuming the spinx board wires to the 7i96
