01:22 AM rifraf: anyone have experience with 5C style collets, i am liking the large bore size in back end, increases possibilities for bar feeder
02:26 AM lcnc-relay: <vibram@> hello
04:45 AM Tom_L: morning
06:57 AM rdtsc-w: morning, team LCNC/EMC2 :)
07:58 AM rdtsc-w: @linext did MIN_FEED_RATE=0.1 work? (you'll want to correct your steps/rev)
09:14 AM -!- #linuxcnc mode set to +vv by osmium.libera.chat
09:39 AM lcnc-relay: <huursabg@> what endmill should i use for helical ramping into steel, i read i should use corner radius and not flat one is that true
09:44 AM lcnc-relay: <voiditswarranty@> huursabg@: I think that's a matter of making it last longer, rather than being required. I could be wrong though
09:54 AM lcnc-relay: <huursabg@> im milling it without air and coolant and the chips are hard to eject and it struggles, any ideas to improve it barring using air/colant? voiditswarranty@
09:54 AM lcnc-relay: <huursabg@> * air/coolant?
09:55 AM lcnc-relay: <skunkworks8841@> air or coolant.
09:55 AM lcnc-relay: <voiditswarranty@> high helix end mills can help too
09:55 AM lcnc-relay: <skunkworks8841@> run your machine upside down?
09:55 AM lcnc-relay: <voiditswarranty@> and roughing with a corn cob
09:55 AM lcnc-relay: <voiditswarranty@> and yeah, air or coolant, why not?
09:55 AM lcnc-relay: <skunkworks8841@> I am here all day.
09:56 AM lcnc-relay: <voiditswarranty@> I've also had some success running a shop vac next to a small machine
09:57 AM lcnc-relay: <voiditswarranty@> less flutes for more chip space
09:57 AM lcnc-relay: <huursabg@> voiditswarranty@: like 45 degree, would it work for steel
09:57 AM lcnc-relay: <voiditswarranty@> if it's designed for it, yes
09:58 AM lcnc-relay: <voiditswarranty@> they do exist
09:58 AM lcnc-relay: <huursabg@> can you run carbide at way lower rpm than its recommended for, like if its meant for 7k can i run it at 2k as long as the chip load is the same
09:58 AM lcnc-relay: <voiditswarranty@> there's also variable helix endmills
09:58 AM lcnc-relay: <voiditswarranty@> yup
09:58 AM lcnc-relay: <huursabg@> so no issues with lower rpm
09:59 AM lcnc-relay: <voiditswarranty@> all this endmill stuff gets way more expensive than just using air or coolant though
09:59 AM lcnc-relay: <voiditswarranty@> I'd try a regular 2 flute center cutting end mill with coolat or air and see how that goes
09:59 AM lcnc-relay: <huursabg@> well i did try with some air and although it helped it didnt solve it entirely, there was still some struggle
09:59 AM lcnc-relay: <huursabg@> so just more air?
09:59 AM lcnc-relay: <voiditswarranty@> what kind of struggle?
09:59 AM lcnc-relay: <huursabg@> the chips dont eject fast enough and they push the z head upwards as it tries to recut them
10:00 AM lcnc-relay: <huursabg@> the ramp angle is 2
10:00 AM lcnc-relay: <voiditswarranty@> are you taking too big of a cut for either the width of the slot or the rigidity of the machine?
10:00 AM lcnc-relay: <huursabg@> 180% of endmill diameter
10:00 AM lcnc-relay: <voiditswarranty@> are you using a center cutting endmill?
10:00 AM lcnc-relay: <huursabg@> ye
10:01 AM lcnc-relay: <huursabg@> its doing 1mm ramps so not deep at all
10:02 AM lcnc-relay: <huursabg@> i cnc-ed a sieg mill and it easily cuts 2mm deep in mild steel 40% stepover but the downwards cutting is the issue
10:03 AM lcnc-relay: <zincboy_ca_on@> Much more force required for plunge cuts.
10:03 AM lcnc-relay: <voiditswarranty@> ah yes, too agressive for the rigidity of the machie
10:03 AM lcnc-relay: <voiditswarranty@> pre-drilling the start can help a lot
10:03 AM lcnc-relay: <huursabg@> sure but then i have to change tools manually
10:03 AM lcnc-relay: <huursabg@> not fun
10:04 AM lcnc-relay: <voiditswarranty@> or increase rigidity and horsepower of the machine
10:04 AM lcnc-relay: <voiditswarranty@> or use a smaller end mill
10:04 AM lcnc-relay: <huursabg@> could it be insufficient cfm/psi or whatever it is it wont solve it
10:04 AM lcnc-relay: <voiditswarranty@> it may not be chip clearance that's the issue, it may just be that it needs more force to plunge
10:04 AM lcnc-relay: <zincboy_ca_on@> I use air blast on steel with variable flute cutters but you need quite a bit of CFM.
10:05 AM lcnc-relay: <huursabg@> i mean it does finish the plunge its just that you can hear it struggle but in the end it will get to the needed depth
10:05 AM lcnc-relay: <huursabg@> no deviation
10:05 AM lcnc-relay: <zincboy_ca_on@> Plunging never sounds great. You will always get some amount of chip re-cutting in my experience.
10:06 AM lcnc-relay: <huursabg@> by plunge i meant helical ramp
10:06 AM lcnc-relay: <huursabg@> my bad
10:06 AM lcnc-relay: <voiditswarranty@> if the results are good, what's the problem?
10:06 AM lcnc-relay: <huursabg@> well idk it might break something, no idea
10:06 AM lcnc-relay: <huursabg@> there isnt much to break but ye
10:07 AM lcnc-relay: <voiditswarranty@> in school one of the first things manual machinists are told to do is push a machine hard enough to break the endmill so they realize how much that takes.
10:07 AM lcnc-relay: <zincboy_ca_on@> Tries that with a 0.010" endmilll, can't feel it 😛
10:07 AM lcnc-relay: <voiditswarranty@> imo part of DIY CNC is finding out what breaks, and fixing it so it doesn't break again
10:08 AM lcnc-relay: <voiditswarranty@> zincboy_ca_on@: heh yeah, we were starting with a huge monarch with 1" HSS tools, those made a bang
10:09 AM lcnc-relay: <zincboy_ca_on@> I find the various feed and speed calculators really good for getting starting point. Then you need to figure out how much you need to back those numbers off for your machine/setup.
10:09 AM lcnc-relay: <voiditswarranty@> my old horizontal mill is so rigid it will break a 1/2" endmill without really any noise, no spring
10:10 AM lcnc-relay: <huursabg@> i got hss-co and hss pm ripper endmills because they are supposed to be sharper and better for my lower rpms and dont have carbide ripper endmills to compare but so far they are perfect, is it true the former are sharper than carbide?
10:10 AM lcnc-relay: <voiditswarranty@> eh, generalities. you can buy ground edge carbide that is craaazy sharp
10:10 AM lcnc-relay: <zincboy_ca_on@> Yes, HSS _can_ be sharper than carbide due to the grain structures.
10:10 AM lcnc-relay: <voiditswarranty@> hss-co rippers are really nice though, they stand up for a long time and make small easy to clear chips
10:11 AM lcnc-relay: <huursabg@> is hss-e done with PM done than normal hss-co?
10:11 AM lcnc-relay: <zincboy_ca_on@> I have a pile of 1.25" diameter by 4" long HSS endmills. Never use them because I am never working on stuff that big 🙂
10:11 AM lcnc-relay: <huursabg@> +better
10:11 AM lcnc-relay: <huursabg@> -done
10:12 AM synfinatic_ is now known as synfinatic
10:13 AM lcnc-relay: <voiditswarranty@> I broke my favorite the other day, 3/4" 6" carbide, almost cried. Got lazy on a setup and it moved....
10:14 AM lcnc-relay: <zincboy_ca_on@> Ouch. That is a pricey mistake.
10:15 AM lcnc-relay: <voiditswarranty@> I was given a resharp from my dad, not gonna replace it 😦
10:15 AM lcnc-relay: <zincboy_ca_on@> I have gone to insert mills for the bigger stuff.
10:15 AM lcnc-relay: <voiditswarranty@> broke right at the shank too, so can't even save it
10:15 AM lcnc-relay: <voiditswarranty@> yeah, I do that a lot mostly, but needed to go to the bottom of a deep hole and didn't have an insert mill long enough
10:15 AM lcnc-relay: <zincboy_ca_on@> Did you take out the tool holder too? I useually find the holder/collet is scrap after a crash like that.
10:17 AM lcnc-relay: <voiditswarranty@> nah it was in a what's it called... DT? I forget. Looks like ER but with a shallower angle. Gets a really good hold on it. There was enough shank stickout that it broke 1/2" away from the collet, thankfully. Pretty much just broke at the end of the flute
10:18 AM lcnc-relay: <zincboy_ca_on@> TG100 probably. DT is more for drills and not endmills. I have a pile of TG100 holders from the PO of the mill. They are great but a little big for most of my work.
10:32 AM roycroft: it got frosty again last night
10:32 AM roycroft: it was not supposed to get below freezing, but it's -4 right now
10:48 AM lcnc-relay: <voiditswarranty@> haha turns out it's a woodworking collet!? OZ25
10:49 AM lcnc-relay: <voiditswarranty@> got a full set of inch collets for it going up to 1"
10:49 AM lcnc-relay: <voiditswarranty@> it's my oddball that I usually just leave a slitting saw arbor in and use my ER32 and normal endmill holders for everything else
10:53 AM lcnc-relay: <voiditswarranty@> OZ25 in an nmtb40 holder, weird. came with a 90 degree head adapted to a 100 year old horizontal mill
11:03 AM roycroft: i did not know there were woodworking-specific collets
11:03 AM roycroft: i got an er32 collet chuck for my wood lathe, and use those collets for wood
11:03 AM rdtsc-w: What's the sense of having a standard (OZ25) if there are a hundred standards? :\
11:04 AM roycroft: it's easier for microsoft to "improve" a standard, making it proprietary, than for them to develop a proprietary standard from scratch
11:04 AM roycroft: perhaps that is the case in the machining world as well
11:06 AM Rab: big_kevin420, thanks for correction re: Machinekit.
11:08 AM Rab: I last used it around 10 years ago, then decided I would be happier with LinuxCNC on x86.
11:27 AM lcnc-relay: <voiditswarranty@> re: standards: https://xkcd.com/927/
11:51 AM lcnc-relay: <voiditswarranty@> yeah it's not a wood collet in an ER, it's an OZ collet chuck
11:52 AM roycroft: er collet holders seem to be almost univerally used by wood turners in their lathes
11:52 AM roycroft: universally, rather
11:55 AM Tom_L: huursabg, 4 flute TiALN coated high helix carbide fwt
11:55 AM Tom_L: ftw
11:57 AM Tom_L: or even 6 flute
11:57 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/cutters/carbide_6flute1.jpg
11:57 AM Tom_L: radius is up to you
12:00 PM memleak: hello everyone!
12:00 PM Tom_L: i've also heard helix ramp is better than a straight ramp move but haven't tested that
12:00 PM rdtsc-w: memleak, where ya been buddy! :)
12:01 PM memleak: playing call of duty world at war on veteran, racking up deaths lol
12:02 PM memleak: people say it's the hardest CoD and i believe it
12:02 PM rdtsc-w: oh that explains it, lol ;)
12:03 PM rdtsc-w: here I thought you were gonna say you got wire EDM machine and have been busy converting it to lcnc :)
12:03 PM memleak: i've been on a big WW2 kick lately, going to watch battle of the bulge soon
12:03 PM memleak: just finished "the pacific" hbo mini series, very good
12:03 PM rdtsc-w: ditto, was very good
12:04 PM Tom_L: voiditswarranty, join the club: http://tom-itx.no-ip.biz:443/~webpage/cnc/temp/IMG_2421.jpg
12:04 PM memleak: i'll probably push that gentoo image out today
12:04 PM memleak: rdtsc-w, do you want to test it?
12:06 PM roycroft: i watched "tora, tora, tora" a few weeks go, and then "midway"
12:06 PM memleak: installs to USB, SATA/SSD/HDD, NVMe, supports BTRFS, F2FS (best for flash devices) EXT4 and XFS, comes with XFCE and LXQt, Okular, FileZilla, guvcview (camera app) and much more, with a 6.12 heavily tuned preempt_rt kernel
12:08 PM memleak: gimp, inkscape and krita
12:09 PM memleak: qt5 and qt6 frameworks too but doesn't yet work with qtpyvcp, that's going to be a big project
12:09 PM memleak: flexgui works though :)
12:42 PM Rab: <rifraf> anyone have experience with 5C style collets, i am liking the large bore size in back end, increases possibilities for bar feeder
12:43 PM Rab: rifraf, my lathe takes 5C collets and I like them well enough...what do you want to know?
12:43 PM roycroft: they have a much smaller working range then er collets
12:43 PM roycroft: if you're ok with that they are fine
12:45 PM Rab: Yes, and danger of springing them if it's exceeded.
12:46 PM roycroft: a nice feature of 5c collets is that you can get an 'emergency' collet
12:46 PM roycroft: which is a solid collet that you can bore to hold whatever part you need to hold in it
12:47 PM roycroft: including odd-shaped parts
12:47 PM Rab: But with a collet stop I think they're more reproducable than ER. One disadvantage of ER is that the collet pulls the tool in when it tightens, and there's no standard stop.
12:49 PM Rab: Also there are a lot of accessories which fit a 5C taper, mandrels and even lathe chuck mounts.
12:50 PM roycroft: 5c collets seem pretty much the standard type for lathes that are larger than mini-lathes
12:50 PM roycroft: i'm not sure there is a "standard" collet type for milling machines - both 5c and er are widely used on mills
12:51 PM Rab: Which mill uses 5C?
12:51 PM Rab: Bridgeport/clones generally use R8.
12:52 PM roycroft: not for the spindle itself
12:52 PM Rab: Oh, for like collet blocks, indexers etc
12:52 PM roycroft: you can get a 5c collet chuck with an r8 taper
12:52 PM roycroft: but i'm mainly taking about rotary tables, collet blocks, etc.
12:53 PM roycroft: my guess would be that folks who start with a lathe tend to use 5c on their mill
12:53 PM Rab: I suspect 5C is better for workholding than for toolholding, but I would have to think through the geometry.
12:53 PM roycroft: folks who start with a mill use either er or 5c, but when they get a lathe they usually get some 5c collet holders for the mill if they don't already have them
12:54 PM Rab: Very short taper on 5C.
01:11 PM rifraf: guys thank you for the input on the 5C, for my home made cnc does seem like a reasonable choice now
01:13 PM Rab: rifraf, if you're building your own machine (lathe?) then 5C would be a good choice. It's certainly the most common lathe collet out there.
01:15 PM rifraf: Rab yep already have the machine made working great, will have to remake headstock, but having hollow drawbar and bar feeder is the aim now
01:15 PM Rab: Not too expensive used, I bought a well-used set of 40 for $80 on eBay.
01:16 PM Rab: Always a risk of getting damaged ones that way, though.
01:16 PM rifraf: and didn't discover 5C till yesterday, i really like the large internal and the external thread
01:18 PM roycroft: watchmaker lathes often use ww collets
01:18 PM Rab: rifraf, look into drawtube and collet closer designs. You may want something automated if you're planning a CNC bar feeder setup.
01:18 PM roycroft: which i think are particular to horology machines
01:20 PM Rab: There are people who sell pre-machined drawtube blanks with the correct thread for 5C. Or if you're lucky, you can snag a cheap closer with drawtube that might work for your application. E.g. https://www.ebay.com/itm/134946406287
01:20 PM rifraf: Rab, will do, am looking for automation, just to feed a bar of stock, not to reload the stock when it runs out, no room in shed for that.
01:20 PM roycroft: if you gl with 5c collets, and you want to keep immediate cost down, you can get a small set of standard size collets for it, and a couple or three emergency collets
01:20 PM roycroft: when you need to hold something that is not a standard size you can use an emergency collet for it
01:22 PM Rab: Note that while 5C collets go up to 1.125", the maximum through bore stock size is 1" (and that can be a squeeze). If you want to feed >1" stock then I would look for something else.
01:22 PM rifraf: Rab this was my first drawtube attempt, using mt2 taper for experiment, waiting on a couple of parts to complete https://studio.youtube.com/video/X9T8L9pdzVs/edit
01:23 PM rifraf: yep, if i can feed 1/2 inch stock is enough for me
01:23 PM Rab: rifraf, Google's asking me to log in, I think that might be your interface and not a public URL for the video.
01:24 PM rifraf: ok try this, just woke up :) https://www.youtube.com/watch?v=X9T8L9pdzVs
01:32 PM Guest20: I updated my LinuxCNC from 2.7.14 wheezy to Debian 12 Bookworm LinuxCNC 2.9.2 RTAI and my latency went from 20K up to 150K+. Would the newer version have been to cause of the increased Latency? Same PC (Dell Optiplex 760 Core2Duo 2.6GHz 2 GB DDR2).
01:33 PM Tom_L: Guest20, you sure you're using a preempt-rt kernel?
01:33 PM Tom_L: doesn't sound like it
01:33 PM Rab: rifraf, there are also nose-mounted collet chucks with integrated closer, but I'm not sure how you would automate them. https://www.ebay.com/itm/281495809729
01:34 PM Tom_L: rifraf, is that bitter beer??
01:34 PM Tom_L: :)
01:35 PM rifraf: Tom_L yep, brand is XXXX
01:36 PM rifraf: XXXX Bitter, its what we drink up this way, the beer from down south more expensive
01:36 PM rifraf: well most cannot handle the full strength version, so xxxx gold much more popular
01:37 PM Tom_L: https://www.amazon.com/KACOME-Pneumatic-high-Speed-Internal-External/dp/B0DM1TQC7Z?gQT=1
01:37 PM Tom_L: more than you want to spend but might offer some ideas
01:40 PM rifraf: yep for sure, how much US$ for that, won't show me because cannot ship it it says
01:40 PM Rab: rigid, watching your other videos. Looks like a great little machine!
01:40 PM Tom_L: $700
01:41 PM rifraf: Rab i am loving it, with the new AC servo is now a dream machine
01:41 PM Rab: Action shot for the bigger version of that pneumatic closer: https://www.youtube.com/watch?v=2lwnn3JXEH8
01:43 PM rifraf: will use compressed air for this new contraption as well, enough pressure for little hobby setup
01:47 PM rdtsc-w: @memleak the Gentoo image? hmm could prolly try it in a VM, but that wouldn't reveal as much as running on real hardware
01:50 PM rdtsc-w: my (in construction) mill is Rpi4B + 7c80, so would choke on Gentoo :)
02:09 PM Guest20: +Tom_L, any thoughts? maybe go back to a 2.8.? release and try that. Everything was working then some how either I crashed it or it crashed. Either way I saw it as an opportunity to updated. And now I'm here. The Debian 12 does actually work. It's when I try to use LinuxCNC that I get a quit operation message.
02:25 PM roycroft: show us the output of uname -v on that machine
02:25 PM roycroft: or leave :)
02:28 PM lcnc-relay: <perry_j1987@> afternoon all
03:51 PM lcnc-relay: <schoch_@> @rifraf a bunch of the chinese lathes with a 38mm bore can accept a mt5 taper, and you can also make a MT5 to 5c adapter.
03:53 PM lcnc-relay: <schoch_@> those spindle are only like $120 bucks and take a pretty common tapered roller bearing size
03:56 PM Rab: https://www.aliexpress.us/item/3256805303166947.html
03:57 PM lcnc-relay: <schoch_@> i'd argue a er collet grips better for non nominal sizes though so you can also consider er32 or er40
03:58 PM lcnc-relay: <schoch_@> also, while that spindle seems much more rigid with a mt5 slug inserted, without it they are a bit thin
03:59 PM lcnc-relay: <schoch_@> https://www.aliexpress.us/item/3256806015066707.html
04:04 PM Rab: A hex collet block like this could go right in the existing chuck, although it would probably need to be carefully shimmed for runout: https://www.aliexpress.us/item/3256806768592196.html
04:04 PM Rab: And they don't provide a measurement for the through bore.
04:07 PM * roycroft wonders what kind of lathe this is
04:07 PM roycroft: if it's a d1 mount you can just buy a 5c collet chuck that mounts directly
04:07 PM Rab: This one: https://www.youtube.com/watch?v=SikDeMiU4sM
04:09 PM roycroft: looks pretty homebrew, with a threaded spindle mount
04:09 PM memleak: rdtsc-w, ah it's for amd64 only. i would like to make a pi5 gentoo image though at some point
04:12 PM memleak: yesterday i learned something great about the pi5. it has a built-in boot menu so you dont need to bake things into the firmware to boot off nvme for example.
04:12 PM memleak: they make it _real_ easy
04:13 PM memleak: does anyone here have a pi5? from what i read, u-boot only offers some of the SoC bring-up code so i'm guessing that boot menu isn't coming from u-boot
04:14 PM memleak: i don't know where it's stored but it looks practically un-brickable
04:14 PM memleak: i know with the pi4, you have the firmware sit in the microSD card but the pi5 can boot without a microSD if i understand correctly.
04:15 PM memleak: so it must have some built-in flash or something that is abstracted away from the user, no idea.
04:20 PM lcnc-relay: <voiditswarranty@> oh yeah the built in boot menu is AWESOME,
04:20 PM lcnc-relay: <voiditswarranty@> I'm running a pi5 for my surface grinder
04:21 PM lcnc-relay: <voiditswarranty@> the pi4 you don't need the firmware on the sd, you can boot off of usb if you set some flags
04:21 PM lcnc-relay: <voiditswarranty@> the pi5 I'm booting directly off of an NVME plugged into the pci bus
04:21 PM lcnc-relay: <voiditswarranty@> no usb drive, no sd card, it Just Works(tm)
04:22 PM memleak: so with a pi5 you dont need to compile any firmware? right?
04:22 PM Tom_L: https://www.raspberrystreet.com/learn/how-to-boot-raspberrypi-from-usb-ssd
04:23 PM lcnc-relay: <voiditswarranty@> correct, I plugged the NVME drive in, booted off of a usb stick, installed raspbian to the nvme using the built in boot loader to select the usb drive, unplugged the usb, and it worked.
04:23 PM lcnc-relay: If you need to change the boot order, you can write a config change and the next time it boots it'll change the default boot order for subsequent boots
04:23 PM memleak: oh nice!
04:24 PM lcnc-relay: <voiditswarranty@> but at no point did I plug an SD card into it. It's a proper computer finally.
04:24 PM memleak: heh
04:24 PM lcnc-relay: <voiditswarranty@> oh and it has a power button, and it correctly hooks into ACPI events and stuff so if my monitor is being stupid I can still shut down gracefully
04:25 PM memleak: oh that's even better!
04:25 PM memleak: i mean i never had an issue with unclean shutdowns with ext4 but it is nice to be able to do is gracefully now in case theres an issue
04:26 PM memleak: *do it gracefully
04:26 PM lcnc-relay: <voiditswarranty@> on crappy sd cards on my pi3 it was a major problem, corruption every third day
04:26 PM lcnc-relay: <voiditswarranty@> when I moved the 4 to a nice usb flash drive that got a lot better
04:26 PM lcnc-relay: <voiditswarranty@> but on my 5 I have a shutdown script to set the GPIO to turn off power to the cnc drives just in case
04:27 PM lcnc-relay: <voiditswarranty@> here's my NVME drive expertly installed with some load bearing painter's tape https://photos.fife.usercontent.google.com/pw/AP1GczPLVJgKK-fii7Tn7Tb1CPVPOabJSN67LEksgJEpz8adIzm0f7rJUruZJg=w1387-h1040-s-no?authuser=0 😄
04:29 PM lcnc-relay: <voiditswarranty@> now if only I could figure out the linuxcnc pi image enough to make it force the HDMI drive on so I don't need my monitor plugged in before I power on the pi for it to enable the hdmi output. The debian HAL configuration is slightly different than the raspbian one
04:30 PM lcnc-relay: <voiditswarranty@> err devicetree. names are hard.
06:13 PM andypugh: Well, my evening set aside to complete a machining job became an evening of replacing a homing prox sensor.
06:14 PM andypugh: (with diversions ncluding 3D printing a clip to hold together the push-release terminal blocks that the prox wires push into.
06:15 PM andypugh: Because the side-plate tends to come off and then the release button pings off into the swarf tray.
06:15 PM xxcoder: doh plans led asray
06:17 PM andypugh: The proxes used to go into this, which was horribly fiddly, especially as it’s at about knee height. https://photos.app.goo.gl/ZhJSadSk4UU2ttqC8
06:18 PM andypugh: These terminal blocks are a definite quality of life improvement, even if it’s only 5 years or so between prox failures. https://photos.app.goo.gl/AfpmUrWiVNc8gM3m8
06:20 PM memleak: oh hey andypugh!
06:20 PM memleak: always fancy seeing you here :)
06:20 PM andypugh: Bertho has been working on cleaning up the RTAI build in master.
06:20 PM memleak: Bertho?
06:22 PM andypugh: BsAtHome on the github
06:22 PM memleak: OH HIM!!
06:22 PM memleak: Freakin genius that guy is.
06:22 PM andypugh: He’s become obsessed with warning-free compilations.
06:22 PM memleak: lmao
06:23 PM andypugh: And seemed to take is as a personal affront when I told him that there were warnings when compiling under RTAI.
06:23 PM memleak: ah alright!
06:23 PM memleak: well hey i'm glad someone is helping!
06:24 PM memleak: having either one of us fork the tree to build linuxcnc against rtai isn't the best approach to say the leasr
06:24 PM memleak: *leastr
06:24 PM memleak: *least
06:24 PM memleak: WOW
06:26 PM bjorkint0sh: folks, you gotta read this: http://www.simonwinchester.com/precision-praise
06:26 PM bjorkint0sh: The Perfectionists: How Precision Engineers Created the Modern World
06:27 PM bjorkint0sh: I spammed the talk yesterday. but the book itself is great.
06:28 PM xxcoder: have you seen that screws of precision youtube vieo?
06:43 PM lcnc-relay: <big_kevin420@> captainhindsight_.@ looks like the esp part is only for communication, and all the gpio on the arduino header go to rp. can probably work something with that
07:00 PM rdtsc: mining blockchain? ;)
07:42 PM lcnc-relay: <big_kevin420@> its the best way to make money with cnc
07:44 PM linext: i found a workaround for F.1 G1 Z-0.5 being too fast
07:44 PM xxcoder: did you try that ini entry for minium speed?
07:45 PM linext: no because i'm running GRBL on a ESP32
07:45 PM linext: the workaround is to divide the G1 motions into smaller steps and put dwell commands in between
07:45 PM linext: such as G4 P3. for 3 seconds
07:46 PM xxcoder: oh so its not linuxcnc?
07:46 PM linext: no, but there's no GRBL on IRC
07:47 PM xxcoder: dont think you menioned it bing grbl last time, but then I might be misremembering
07:47 PM linext: i didn't yesterday
07:47 PM linext: the esp32 seems fast enough to keep up, not sure i need a full linux computer
07:48 PM linext: the arduino 328p based grbl was too slow
07:48 PM xxcoder: sure though we thought you was using linuxcnc so some of solutions or ponental solutions was all for linuxcnc
07:57 PM lcnc-relay: <captainhindsight_.@> big_kevin420@ yeah, i didn't look at the schematic yet
08:03 PM lcnc-relay: <big_kevin420@> yeah all the gpio are to the rp2040 and the is conencted to the via spi/uart
08:03 PM lcnc-relay: <big_kevin420@> limited gpio access for the esp
08:04 PM lcnc-relay: <skunkworks8841@> grbl is pretty basic. If that is all you need - then great!
08:04 PM xxcoder: linext left bit ago
08:04 PM lcnc-relay: <skunkworks8841@> oh
08:04 PM lcnc-relay: <skunkworks8841@> well.. I stand by what I said.
08:05 PM xxcoder: indeed. its fine for easy machine
08:36 PM memleak: andypugh, if BsAtHome is going to be doing a lot of fixes I think we should just give him commit rights at some point.
08:36 PM memleak: he seems like a good soul.
08:37 PM memleak: he certainly knows his stuff
