12:43 AM boostedcabbage[m: is there a setting that makes spindle.0.at-speed work? i have motion without this pin being true
01:00 AM miss0r7: mornin
01:10 AM miss0r7 is now known as miss0r
01:12 AM boostedcabbage[m: hello
01:16 AM boostedcabbage[m: i had some nets wrong. looks good now
02:03 AM mits[m]: Is there some config item, ini or hal that enforces linuxcnc is running on an RT kernel?
02:10 AM Deejay: moin
02:28 AM boostedcabbage[m: it's alive. makes chips

02:29 AM XXCoder: niiice
02:29 AM XXCoder: congats
02:29 AM boostedcabbage[m: thanks
02:30 AM boostedcabbage[m: the PID is pretty jacked, but it can be tuned
02:32 AM boostedcabbage[m: the 3d printed low/high gear is pretty loud too. this is fun, but man i need a real lathe
02:33 AM XXCoder: gears have grease?
02:34 AM boostedcabbage[m: not much 🙂
02:36 AM boostedcabbage[m: that chuck runout is real. i hit the spindle with a hammer and apparently didn't fix where the chuck mounts
02:39 AM * boostedcabbage[m uploaded an image: (846KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/pwLliKuFppqwUiwDzqhBBaxX/PXL_20230316_073407281.jpg >
02:40 AM boostedcabbage[m: 10/10 safest, most reliable linuxcnc setup
02:42 AM XXCoder: lol you should have seen my cnc router electrics
04:39 AM Tom_L: morning
04:46 AM Tom_L: boostedcabbage[m, you can use the spindle.0.at-speed with a 'near' component:
04:47 AM Tom_L: net spindle-cmd-rps <= spindle.0.speed-out-rps
04:47 AM Tom_L: net spindle-cmd-rps => near.0.in1
04:47 AM Tom_L: net spindle-at-speed <= near.0.out
04:47 AM Tom_L: net spindle-at-speed => spindle.0.at-speed
04:48 AM Tom_L: then set a value for near.0.scale
04:49 AM Tom_L: net spindle-velocity <= hm2_[HOSTMOT2](BOARD).0.encoder.01.velocity
04:49 AM Tom_L: net spindle-velocity => near.0.in2

06:53 AM JT-Cave: morning
06:53 AM alexfloca: hello everybody, did anyone notice a problem with the motion.feed-inhibit pin in the current release?
06:54 AM alexfloca: even if the pin is set true, the motion does not stop. i have tested setting the bit true before moving the machine and also tested setting the bit true during a move, both with same results, the machine moves with no restriction
06:59 AM jpa-: alexfloca: by "current release" do you mean 2.8.4 or something else?
06:59 AM alexfloca: yes, 2.8.4
07:00 AM alexfloca: i have used this function in 2.7.x with no problems before
07:00 AM travis_farmer[m]: were you jogging or running G-Code?
07:01 AM alexfloca: tried it while jogging
07:01 AM alexfloca: i could also write a g-code for testing
07:01 AM travis_farmer[m]: Note: feed-inhibit applies to G-code commands -- not jogs.
07:01 AM jpa-: for me feed-inhibit is working ok with 2.8 during G-code running
07:01 AM alexfloca: ok, let me try it, if it works during g code it should be ok
07:01 AM alexfloca: brb
07:04 AM alexfloca: yes, it works during g-code execution
07:05 AM alexfloca: have expected it to work also with normal jogging, but it's fine like this
07:05 AM alexfloca: thanks for the hint
07:05 AM travis_farmer[m]: no problem, glad i could help :-)
07:09 AM Tom_L: light snow this afternoon 65F currently
07:09 AM jpa-: also during G-code execution i think it will not stop travel moves (G0)
07:10 AM alexfloca: will also try that ;)
07:12 AM travis_farmer[m]: on a forum i moderate (not my personal forum), i got a promotion to Administrator level. :-)

07:32 AM ZincBoy[CAON][m]: You need a fiber laser to mark metal. A CO2 laser will cut metal at sufficient power levels (>150W absolute minimum with O2 assist) but will not mark metals. Metal is highly reflective at the 10.6um wavelength of the CO2 laser. A fiber laser has high enough peak power to etch the surface. There are some metal marking paints that work with both CO2 and diode lasers you could try.
08:25 AM Loetmichel: Hey, anybody here that knows what thread is on the head of a classic dremel(clone)? the plastic one that holds the two enclosure halfs together. Have to make an adapter for 43mm throat tool holder.
08:27 AM travis_farmer[m]: google says 19mm x 2mm
08:29 AM Loetmichel: travis_farmer[m4: i measured 17.2mm by 1.4mm... seems off
08:31 AM travis_farmer[m]: another source says 3/4" -12 UN
08:35 AM unterhaus: yeah, it's the 3/4" one
08:35 AM unterhaus: dremels have been the same for 60 years
08:35 AM unterhaus: no way an american company would use metric
08:35 AM unterhaus: 60 years ago
08:36 AM unterhaus: anyway, I have a tap for it sitting around somewhere
08:36 AM unterhaus: the chinese clones are not the same, it's a pita
08:39 AM unterhaus: okay, possibly since 1935. Pretty optimistic time to introduce a new type of tool
09:18 AM perry_j1987: morning
09:46 AM elia: anyone here did a turcite buildup on damaged dovetail ways?
09:47 AM elia: I'm not planning on doing that right now, but I definitely want to know my options - the FND32 mill turned out to have gotten some horrible damage to the Y axis ways
09:47 AM JT[m]: Tom_L Blue is ordered
09:48 AM elia: it'll work, after knocking out the high spots and ensuring proper oiling it should still provide usable accuracy, but it definitely qualifies for a proper reconditioning
09:48 AM elia: if I can manage to find a local-ish place that can handle the entire main casting on a grinder to remove the damaged layer, I will seriously consider it
09:49 AM elia: the damage appears too deep for just scraping to make any sense whatsoever)
09:49 AM elia: although I might be wrong about that, I'll definitely post some photos and measurements as soon as that part gets cleaned uo
09:49 AM elia: *up
09:51 AM unterhaus: I know someone through work that has a company called "newway" that specialized in some kind of rebuilding of ways
09:51 AM unterhaus: don't know if it's turcite though
09:52 AM unterhaus: they moved into air bearings though
10:02 AM CaptHindsight[m]: https://mtsandtg.com/turcite-application
10:10 AM CaptHindsight[m]: what the websites that sell turcite don't mention is that the ways have to be completely covered to prevent contamination
10:38 AM unterhaus: how do you tell google you want a socket for a 3/8" head grub screw?
10:40 AM unterhaus: it turns out it's a female pipe plug socket, not carried by the local suspects
11:06 AM perry_j1987: chat gpt to the rescue unterhaus
11:07 AM perry_j1987: sent you a msg lol
11:18 AM unterhaus: it turned out to be far easier than I thought to adjust the door, once I loosened the set screws a little the pulley slipped to the right place
11:18 AM perry_j1987: nice
11:19 AM unterhaus: I don't know how a 3/8" fastener uses a 10mm wrench, but it worked
11:19 AM unterhaus: couldn't find a 3/8" that fit on it
11:30 AM roguish[m]1: hey, have you guys seen this? https://www.pbs.org/newshour/show/american-company-accused-of-violating-sanctions-doing-business-with-russian-arms-industry
11:33 AM roycroft: i hadn't seen that, but it does not surprise me
11:34 AM Tom_L: not the first time they've been in trouble
11:34 AM roycroft: president eisenhower warned us about their ilk
11:35 AM roycroft: i'm going to have another go with the laser engraver in a bit
11:36 AM roycroft: i found a pile of small red oak cutoffs from a project a while back that are perfect for testing it
11:36 AM roycroft: i'll sand them to p1200 or p1500 and then do some high resolution engraving to see how sharp the images are
11:38 AM roycroft: that plywood i used last night is a bad test - i thought it was baltic birch but when i looked at it more closely i realized it was just cheap domestic birch ply, with thinner than paper veneers
11:41 AM Tom_L: so while driving across town to here i left and it was 65F and as i crossed on the highway i watched the temp drop from that to 45F in 5-10 min
11:48 AM unterhaus: My understanding about the Haas deal is that it really isn't their fault
11:49 AM unterhaus: They finally caught up to their distributor that was the real problem
11:50 AM unterhaus: too bad they lost the suit against Hurco, the response was pure comedy
11:52 AM roycroft: it's too bad that big corporations put money before morality and patriotism
11:54 AM bjorkintosh: roycroft, you would not be surprised if you realized that corporations serve a different purpose from individuals.
11:55 AM roycroft: i did not say i was surprised
11:55 AM roycroft: i said it's too bad
11:55 AM bjorkintosh: that's too bad. you should be surprised so that my statement would work!
11:56 AM roycroft: in fact, i stated above that i had not heard about the haas issue before roguish pointed it out, but that it did not surprise me
11:56 AM roycroft: <roycroft> i hadn't seen that, but it does not surprise me
11:56 AM bjorkintosh: oh. I hadn't seen that.
11:56 AM roycroft: <roycroft> president eisenhower warned us about their ilk
11:56 AM bjorkintosh: but it doesn't suprise me (either)
11:57 AM bjorkintosh: I wondered for a while why the USSR had not jumped on CNC back when it existed.
11:57 AM bjorkintosh: and then I realized they really did not care at all about productivity.
11:57 AM bjorkintosh: so it didn't matter.
11:57 AM roycroft: because soviet technology is potato
11:58 AM bjorkintosh: efficiency was not a fundamental requirement. if it was, they merely said so, they did not do so.
11:58 AM bjorkintosh: so machines which increased efficiency were not prioritized.
11:58 AM roycroft: efficiency is not necessary when you can enslave the masses
11:58 AM bjorkintosh: 'xactly. cheap labor is a curse.
11:58 AM roycroft: and threats of gulag is a form of enslavement
11:59 AM roycroft: speaking of lack of efficiency
11:59 AM unterhaus: they really should change the laws surrounding corporations to make it a requirement to serve the public interest
11:59 AM roycroft: i think i'm going to set up for another go at the laser engraver now
12:00 PM bjorkintosh: I thought they would have been all over it because there was a big cybernetics push at some point in the '70s, and their economy was centrally planned.
12:00 PM unterhaus: right now, if you make more money not serving the public interest, it's essentially a requirement to not do so
12:00 PM roycroft: courts have ruled that corporations *cannot* serve the public interest
12:00 PM roycroft: they are required to only serve the shareholders
12:00 PM bjorkintosh: unterhaus, the very corporations set the public agenda through a very efficient system of lobbyists and propaganda. it's not going to change any time soon!
12:00 PM roycroft: although we do have a fairly new corporate structure here in oregon now - b corporations
12:00 PM roycroft: the 'b' standing for public benefit
12:01 PM bjorkintosh: I mean, they invented too big to fail but screw the common man.
12:01 PM bjorkintosh: (or person)
12:01 PM roycroft: their corporate charter has the public benefit embedded in it
12:01 PM roycroft: the courts have not found a way to rule around that yet
12:01 PM roycroft: i'm sure they'll figure something out though
12:02 PM bjorkintosh: the judges are afraid that their retirement funds would be tarnished by corporations if they annoy them. so they typically rule in their favor.
12:02 PM roycroft: we can't have people going around voluntarily doing good things when there is greed to be had
12:02 PM travis_farmer[m]: that's a sad truth
12:03 PM bjorkintosh: perhaps one day ChatGPT-99 would emerge wholly and independent and objective enough to be the ultimate judge. (cue Kafka-esque sci-fi horror story)
12:03 PM unterhaus: all the machinists say that at least they weren't selling the Russians good machine tools, only Haas machine tools
12:04 PM bjorkintosh: funny.
12:04 PM bjorkintosh: HAAS is pretty decent.
12:04 PM bjorkintosh: and russian tools are half-bad. so they got the right machinery.
12:05 PM unterhaus: Someone got a Russian engineer to give a talk at the university, and it was amazing how crude his work was
12:07 PM unterhaus: I thought they all had pirated copies of excel at least
12:08 PM perry_j1987: ugh whoever made this drawing and failed to call out certain dimensions...
12:09 PM unterhaus: in my defense, I sent you a solid model with all dimensions defined
12:10 PM jpa-: and the solid model was in the universally recognized unit of deci-inches
12:10 PM unterhaus: bananas actually
12:11 PM unterhaus: it's the only self-defined system of units
12:13 PM unterhaus: banana truck crashed near here last night, setting back local metrology efforts by about a week
12:15 PM unterhaus: There is an effort to define the standard banana in terms of metric units
12:15 PM bjorkintosh: that's just bananas.
12:17 PM unterhaus: If they had had bananas in medieval Britain, we would be using bananas instead of feet
12:17 PM bjorkintosh: it's unfortunate they had feet.
12:18 PM unterhaus: did the first person that decided they needed a better unit of measurement than the king's foot meet a bad end?
12:18 PM unterhaus: I guess that's why it was the French that did it, they got rid of their king first
12:19 PM bjorkintosh: I mean... the Ruler was the ultimate authority.
12:19 PM bjorkintosh: isn't that why they are called Rulers?
12:19 PM unterhaus: interesting question
12:19 PM bjorkintosh: it's the same word in french as well.
12:19 PM bjorkintosh: same as the instrument.
12:21 PM bjorkintosh: a Regal Rule of Regulations Registered for Regiments. same root word: rule
12:21 PM bjorkintosh: (reg in latin)
12:28 PM * roycroft is engraving, and thinks the results will be better this time
12:34 PM unterhaus: the wikipedia page about metrology doesn't mention bananas at all
12:34 PM roycroft: you need to look on the radioactivity page to learn about bananas
12:37 PM roycroft: so i have a small fan blowing across the path of the laser engraver
12:38 PM roycroft: i can't smell any smoke at all in my shop - it's a minimal amount, and the fan seems to be dispersing it well
12:38 PM travis_farmer[m]: don't stare at the laser spot ;-)
12:39 PM roycroft: i haven't and won't
12:40 PM roycroft: but i do have some really groovy orange tinted goggles that i wear whenever i'm out there and the laser is operating
12:40 PM travis_farmer[m]: even with the cheap "laser" glasses, you can get a similar result as welding flase
12:40 PM travis_farmer[m]: flash
12:40 PM roycroft: even with the goggles on i avert my eyes as much as possible
12:41 PM roycroft: i just glance at the work piece to check progress then look away
12:41 PM roycroft: but right now i'm in my office, and the engraver is in my shop
12:41 PM travis_farmer[m]: excellant!, i know from experiance, about the laser glasses ;-)
12:41 PM roycroft: so i'm far away from it
12:42 PM * travis_farmer[m] goes to check on the water infiltration issue in the basement...
12:43 PM roycroft: i just spent too much money on spectacles to waste it putting my eye out!
12:47 PM * travis_farmer[m] found no water in basement, but the cement is discolored, so it is thinking about it...
12:47 PM roycroft: maybe a rat peed on the cement
12:48 PM travis_farmer[m]: really big rat, if it made that much discoloration...
12:48 PM roycroft: or a heavy drinker
12:48 PM travis_farmer[m]: lol
12:49 PM travis_farmer[m]: no, when the snow melts, it is too much for the ground to take care of, so it comes into the basement
12:53 PM -!- #linuxcnc mode set to +v by ChanServ
12:54 PM -!- #linuxcnc mode set to +v by ChanServ
01:18 PM roycroft: hmm, i just read that google glass is being discontinued again
01:19 PM roycroft: i never knew it had come back
01:20 PM roycroft: the engraving is going very slowly - increasing the resolution to 2k is making it take about 4x longer
01:20 PM roycroft: but the results look good so far
01:30 PM unterhaus: we were going to work on google glass, but the university decided it was not research or something
01:30 PM unterhaus: that was after google stopped selling them, so I figured they weren't giving up
01:32 PM unterhaus: proving law zero of bureaucracy, everyone can say "no"
01:33 PM unterhaus: definitely would have funded someone's phd
01:34 PM skunkworks: It really looks like the little emco's x axis is going to have an extra inch of movment after the ball screw replacment.
01:36 PM unterhaus: I posted a free woodstove 10 minutes ago and someone already asked if it's still available
01:37 PM unterhaus: I never thought about the advantage of putting ballscrews on my lathe. The acme screw runs out well before the end of the ways
01:38 PM unterhaus: actually, it's the rack that runs out, the acme screw goes quite a bit further
01:38 PM unterhaus: but I haven't been able to use the acme screw anyway
01:46 PM skunkworks: This has ball screws. (smaller ones) but the nut assembley is a bit shorter. I could probably make the travel even more.. but the emco is such a small lathe anyway
01:46 PM skunkworks: 2" vs 3" is quite an improvement.
01:49 PM unterhaus: it seems beefier than the little manual one we had at work
01:54 PM skunkworks: I am impressed at how they machine.
01:55 PM skunkworks: https://www.youtube.com/watch?v=pzk0wM1HERY
01:59 PM XXCoder: looks very clean
03:18 PM roycroft: https://roycroft.us/LaserPecker/LaserPecker3.jpeg
03:18 PM roycroft: the second go was much better
03:19 PM roycroft: i guess the next step is to figure out how to print my own files
03:20 PM roycroft: and that python extension for inkscape might be the ticket
03:21 PM XXCoder: nice
03:22 PM XXCoder: not surpised that it varies a little bit. darker spots would burn more
03:23 PM roycroft: i sanded that piece of red oak to p1500, so it was nice and smooth
03:23 PM roycroft: i also upped the resolution from 1k to 2k, and did two passes
03:23 PM roycroft: all that meant a much crisper, darker, and deeper engraving
03:23 PM roycroft: but it also took 2 hours instead of the 30 minutes last night's test took
03:24 PM roycroft: fortunately my logo will be smaller and should go much faster
03:25 PM roycroft: that is actually deep enough that i could fill it with opaque paint if i wanted to
03:25 PM roycroft: although 3 passes would probably be better for a paint fill
03:26 PM roycroft: if i decide to start doing that i'll get a more capable laser that is much faster, and can engrave to full depth in a single go
03:27 PM XXCoder: yeah
03:27 PM XXCoder: new one could do infill burns while small one just do burn
03:28 PM roycroft: this device gets me going right now, though, at minimal cost
03:28 PM roycroft: it was kind of free - i just had a cd mature, and it had accumlated $300 in interest
03:29 PM roycroft: i used that interest money to pay for the laser
03:31 PM XXCoder: nice
03:31 PM roycroft: i also just read that the laserpecker isn't really limited to 100mm x 100mm
03:32 PM roycroft: it can only print a single job at that size, but you can offset the job in the gcode, and if you tile the job, it will engrave up to 150mm x 400mm
03:32 PM XXCoder: nor surpised. I bet you could rise it for larger area, but at lower resolution and burn strength
03:32 PM roycroft: no, because it has to focus at exactly 200mm
03:32 PM XXCoder: interesting
03:32 PM XXCoder: hm yeah makes sense
03:33 PM roycroft: my logo will usually engrave at about 10mm x 100mm, so the stock setup will be fine
03:33 PM roycroft: but it's interesting to know that i could go bigger if i needed to
03:33 PM XXCoder: yeah. im not sure how tiling would work though
03:34 PM roycroft: i think it would probably get a bit distorted at the extremes, and out of focus
03:35 PM roycroft: i don't know how the laser is set up in the head
03:35 PM roycroft: whether it has an auto-adjusting lens, or just a moving mirror
03:35 PM roycroft: if just the mirror, then anything outside the 100mm x 100mm footprint will probably not turn out so well
03:36 PM XXCoder: good thing to test at some point
03:36 PM roycroft: yeah, if i ever get bored
03:36 PM roycroft: so maybe in a few years :)
05:28 PM XXCoder: wow new winston moy video
05:28 PM XXCoder: been a bit. guy dont make videos often but usually interesting
05:47 PM unterhaus: one of the email lists I'm on got 120 emails since the last time I looked
05:47 PM unterhaus: too much work
06:25 PM JT[m]: We made it to Shreveport
06:31 PM skunkworks[m]: lol - makes me think of trueblood
07:52 PM roycroft: so from what i can determine so far, the only way to engrave my logo with this laser thing is to print the logo out and take a picture of it with my ipad's camera
07:53 PM roycroft: as an exercise, i tried that, and it's going as poorly as one would expect
07:53 PM roycroft: the manufacturer's support website, to which i was referred, returns a 404
07:58 PM XXCoder: ugh
07:58 PM XXCoder: no way to import image or what
07:58 PM XXCoder: if the bird logo is only thing that can be engraved sharply then it isnt worth much
08:01 PM roycroft: one can design images in the app, but it's a really sucky app
08:02 PM roycroft: there is a desktop app that supposedly imports files, but it only works with the laserpecker 2 and up
08:02 PM roycroft: not the 1 pro
08:03 PM JT[m]: That sucks
08:03 PM roycroft: yeah
08:03 PM roycroft: i may have to look at something else
08:03 PM roycroft: and it's too bad, because i really like the design of this device
08:04 PM roycroft: the 2 starts at $900
08:04 PM XXCoder: yeah yet another case of good hardware beyond shit software
08:04 PM XXCoder: maybe look up running alternate software?
08:04 PM roycroft: and it can't mount on a tripod like the 1
08:04 PM roycroft: i haven't found anything
08:04 PM XXCoder: sucks.
08:04 PM Suspect: maybe try https://github.com/yy502/inkscape-laserpecker
08:05 PM roycroft: the inkscape plugin supposedly works with the 1, but i don't see how to import the file, and the plugin doesn't work right
08:05 PM roycroft: i may be able to fix the latter
08:05 PM roycroft: but i still don't know how to get the gcode file on the ipad in the app
08:06 PM roycroft: i'll spent a bit more time with it before it goes back
08:06 PM roycroft: i want it to work
08:06 PM XXCoder: "Output Gcode file should end in .txt otherwise the LaserPecker App won't recognise it."
08:06 PM XXCoder: weird
08:06 PM XXCoder: its often .nc or whatever not txt
08:07 PM roycroft: yeah, but i don't see any way for the app to see it
08:07 PM XXCoder: 1 mb limit on l1/pro
08:07 PM roycroft: that should not be a problem
08:07 PM XXCoder: theres video tutorial
08:07 PM roycroft: it's small and simple
08:07 PM XXCoder: https://youtu.be/neA5kYvSX6w
08:07 PM roycroft: thanks
08:09 PM roycroft: oh, i watched that one already
08:09 PM XXCoder: it wouldnt help me much at all. no captions, but then I dont own laser l1
08:09 PM roycroft: the problem is that i've scaled the logo down so it fits easily in the footprint, but the inkscape plugin thinks it's too big, and refuses to generate gcode
08:09 PM roycroft: there's no audio at all
08:09 PM roycroft: you get as much as i do
08:10 PM XXCoder: wrong units?
08:10 PM roycroft: there's no point in captioning silence :)
08:10 PM roycroft: it may be a unit conversion thing
08:10 PM XXCoder: what units does cam expect
08:10 PM roycroft: i've set the units to mm and to inches
08:10 PM XXCoder: would be funny if it was actually pixels
08:10 PM roycroft: and the plugin still complains
08:10 PM XXCoder: (px)
08:10 PM roycroft: the engraver app works in pixels
08:11 PM roycroft: that's where the 1k and 2k "resolution" numbers come from
08:11 PM XXCoder: hmm maybe scale it to px and see if it works
08:11 PM roycroft: the image area is 100mm x 100mm
08:11 PM roycroft: so "1k" is 1k pixels/100mm
08:11 PM roycroft: and "2k" is 2k pixels/100mm
08:12 PM roycroft: No path selected. Work on all available paths.
08:12 PM roycroft: Graphics are too big: 354.0 x 20.9.
08:12 PM roycroft: Scale it down to within 100x100 for LaserPecker to function properly.
08:12 PM roycroft: that's the error i get
08:12 PM roycroft: the image is 87mmx9mm
08:12 PM roycroft: well under 100mm x 100mm
08:13 PM XXCoder: what units is "354"?
08:13 PM XXCoder: maybe you have to run though all units till you get that number from picture size
08:13 PM XXCoder: oh wait
08:13 PM XXCoder: is it reading Document size?
08:13 PM XXCoder: rather than object size?
08:14 PM roycroft: that document size is 87mm x 9mm
08:14 PM roycroft: the object fills the document footprint
08:19 PM roycroft: i found another video that purports to both generate the gcode and transfer it to the ipad
08:20 PM XXCoder: ok
08:21 PM roycroft: the software it uses is called laserweb, which is freely-available
08:24 PM roycroft: it uses dropbox to transfer the file, but i can live with that if necessary
08:24 PM roycroft: once the logo is on the ipad i probably won't need to deal with it again
08:24 PM Suspect: laserweb is browser based https://laserweb.github.io/LaserWeb4/
08:28 PM XXCoder: Suspect: setup is bit annoying
08:29 PM XXCoder: used it for my cheap lkaser thing
08:30 PM Suspect: yea internet connection here is crappy so i avoided it
08:36 PM roycroft: there's a native mac os app
08:37 PM roycroft: but again, for me this is pretty much a one and done thing
08:37 PM roycroft: unless i decide i need my logo in different sizes
08:37 PM roycroft: it's not something i would use regularly
08:38 PM XXCoder: eh sure but id suggest take notes anyway
08:38 PM XXCoder: in case
08:40 PM roycroft: https://www.youtube.com/watch?v=2I_ziR_dfAc
08:40 PM roycroft: that video explains it well
08:41 PM roycroft: it's good to be deaf though
08:41 PM roycroft: the narrator has an annoying chicago accent
08:41 PM roycroft: and he's a white sox fan
08:41 PM roycroft: so even for those who can hear, i recommend muting and captioning
08:42 PM * roycroft has a concert tonight, and needs to get ready
08:42 PM roycroft: i'll install laserweb later on, and see if that works forme
08:42 PM roycroft: i hope it does, because i'd rather not return the laserpecker
08:47 PM CloudEvil: https://www.youtube.com/watch?v=I5GvwWKkBmg
08:47 PM CloudEvil: World's first video of 56 transition controls for a triple inverted pendulum.
08:49 PM XXCoder: roycroft: have fun
08:49 PM Tom_itx: roycroft, https://github.com/yy502/inkscape-laserpecker
08:50 PM XXCoder: CloudEvil: dang a update to that
09:06 PM Tom_itx is now known as Tom_L
10:55 PM mits[m]: are there guidelines for HOME_SEARCH_VEL and HOME_LATCH_VEL for certain types of machines?
10:56 PM mits[m]: I have no clue about rough values that I should be using
10:56 PM mits[m]: I set it to 10 and 0.5 ages ago, but maybe I'm being overly cautious
11:32 PM TurBoss8676[m]: mits (@_discord_223249788139864064:jauriarts.org) have you seen this docs section? http://linuxcnc.org/docs/html/config/ini-homing.html#_homing_sequence
11:56 PM mits[m]: I have, am I missing suggested values?
11:58 PM mits[m]: I have, I'm not seeing any suggested values though
