12:08 AM roycroft: ok, i think i have the e-stop figured out now
12:24 AM * roycroft goes to do some quick wiring for a test
12:24 AM xxcoder: awesome
12:24 AM fluffywolf: first step, stick your hand in the spindle, then see if you can reach the button and it stops. :P
12:25 AM roycroft: i was going to just use 5v for the e-stop and limit switches, but i saw a note in the forum from pcw saying that for mechanical switches 24v is much better over the long term
12:26 AM roycroft: so maybe i need to get a 24v psu for that stuff
12:26 AM roycroft: i'm testing with the one i got from xxcoder now, but it's way too big to fit in the cabinet now that i've swapped in that second 48v psu
12:27 AM xxcoder: can always use dc-dc
12:27 AM fluffywolf: wolfy bedtime. bbl.
12:27 AM xxcoder: it can be quite small, if amps isnt too high
12:27 AM roycroft: yeah, that's what i'm thinking
12:27 AM roycroft: it should be milliamps
12:28 AM xxcoder: you do have 12v one, but I have no idea what upper volt bound is, been too lomg. I think 24v does work but your goal is not to use that
12:28 AM roycroft: it's 40v, unfortunately
12:28 AM roycroft: i checked already
12:28 AM roycroft: if it were 48v i'd use it and decide 12v is better than 5v
12:29 AM roycroft: and i can run the switches with 5v for now
12:29 AM roycroft: i just don't want to have to remodel the cabinet in six months or a year
12:31 AM roycroft: so i just read that the paramount merger was approved by the fcc yesterday
12:31 AM roycroft: that must have been before the south park episode aired :)
12:31 AM xxcoder: double dc-dc? 48v to whatever, to 12v
12:32 AM xxcoder: or 5v if prefer
12:32 AM roycroft: i'm finding plenty of bucks for cheap
12:32 AM roycroft: but they're all big
12:32 AM roycroft: i need something tiny
12:32 AM xxcoder: im sure theres better ones that can do it in single step
12:33 AM roycroft: 24v or 12v would be fine - it doesn't matter
12:33 AM roycroft: and as i said, 5v will work, but it might not be as reliable as i'd like
12:34 AM xxcoder: pretty lot of those is high amps
12:34 AM xxcoder: found 48 to 24v for 1a but yeah
12:35 AM xxcoder: yeah dunno lol
12:36 AM roycroft: this will not be a production machine that runs for 8 hour/day or more
12:36 AM roycroft: so reliability may not really be an issue
12:36 AM roycroft: and the psu is just for limit switches and the e-stop
12:36 AM roycroft: neither of which should engage often
12:37 AM roycroft: so 5v is looking like a good medium- to long-term solution given the circumstances
12:37 AM roycroft: it will also be living inside my house, so corrosion is not a concern
12:37 AM xxcoder: if reliability issue maybe boosted from 5v to say 10v
12:37 AM xxcoder: might be plenty dunno
12:41 AM roycroft: that would still require another psu or a voltage reducer
12:42 AM roycroft: i have 120vac, 5vdc, and 48vdc to work with
12:42 AM lcnc-relay: <meisterdippel@> moin
12:42 AM lcnc-relay: <meisterdippel@> git status
12:44 AM roycroft: i am still a sniveling little rat-face git
12:44 AM roycroft: and let me introduce my wife, dreary fat old boring git
12:56 AM Deejay: moin
04:17 AM -!- #linuxcnc mode set to +v by ChanServ
05:03 AM -!- #linuxcnc mode set to +v by ChanServ
05:36 AM lcnc-relay: <travis_farmer@> Morning
05:38 AM lcnc-relay: <meisterdippel@> it's lunchtime and the earth is flat 😂 so how long do you sleep 😱
08:13 AM lcnc-relay: <skunkworks8841@> time zones are complicated
09:17 AM lcnc-relay: <.le_potato@> morning
09:17 AM lcnc-relay: <.le_potato@> skunkworks8841@: it is, so i wakeup/sleep cet time lol
09:17 AM lcnc-relay: <.le_potato@> but its 4pm rn
09:18 AM lcnc-relay: <.le_potato@> sorry not cet, something us time i mean :3
09:19 AM lcnc-relay: <.le_potato@> PST!
09:41 AM -!- #linuxcnc mode set to +v by ChanServ
09:42 AM JT-Shop: success!
09:42 AM lcnc-relay: <skunkworks8841@> which one?
09:44 AM lcnc-relay: <skunkworks8841@> welded up another bracket - might be getting used to welding again.
09:46 AM roycroft: hi folks
09:47 AM roycroft: it is friday!
09:48 AM lcnc-relay: <skunkworks8841@> Finally!
09:49 AM roycroft: another day in paradise
09:49 AM roycroft: i'm about to drop my car off for the new clutch
09:49 AM roycroft: and i got my e-stop wired and tested last night
09:49 AM lcnc-relay: <skunkworks8841@> the toyota has 260k miles and the original clutch.. How do you drive that thing? 😉
09:50 AM roycroft: i need to add the logic for what i want linuxcnc to do when i mash the button
09:50 AM roycroft: the veloster clutch is a 100k mile wear item - i haven't seen it but i'm sure it's pretty tiny
09:50 AM roycroft: and the car has just under 100k miles
09:51 AM roycroft: but, more importantly i think, it's how did the previous owner drive it
09:51 AM roycroft: the clutch was really grabby when i bought the car
09:51 AM roycroft: so much so that i had a hard time not stalling the engine when engaging the reverse gear
09:51 AM roycroft: i've been driving a manaul transmission since i was in high school, so it's not like this was my first vehicle with a clutch
09:52 AM roycroft: i suspect it was a little wonky when i got it
09:52 AM lcnc-relay: <skunkworks8841@> the toyota took a long time to get used to.. I don;t know what the deal was.
09:52 AM lcnc-relay: <skunkworks8841@> the VW's clutch is so effortless in comparison...
09:52 AM roycroft: i'm not happy about this - it's a $1k repair that i can't afford right now
09:53 AM roycroft: but oh well
09:53 AM roycroft: i have two trips to town to make this weekend, and with the vehicle as it is, they would be slow going
09:53 AM roycroft: and my fuel economy has gone way down since it started slipping
09:54 AM lcnc-relay: <skunkworks8841@> I bet
09:54 AM roycroft: i have to drive in a lower gear than normal
09:54 AM roycroft: so i'm driving at 3krpm instead of 2.2krpm
09:54 AM roycroft: but i only have three more blocks to go with that situation
09:55 AM lcnc-relay: <satiowadahc@> Why does building documentation take longer than compiling the source code?
09:56 AM lcnc-relay: <skunkworks8841@> Do you need the documentation? Pretty sure you can compile without
09:59 AM roycroft: we're at pl4 now - the feds have declared it
09:59 AM roycroft: a little later than last year, but a little earlier than usual
09:59 AM lcnc-relay: <travis_farmer@> pl4?
09:59 AM roycroft: pl4 is pretty severe - it's one level below mobilizing the military to help with the fires
10:00 AM lcnc-relay: <satiowadahc@> Yea. Apparently links are weird in adoc. Fixing a mistake.
10:00 AM roycroft: preparedness level - it's how we prepare to fight wildfires
10:00 AM lcnc-relay: <travis_farmer@> i c
10:00 AM roycroft: at pl5 we not only bring in the military, we bring in canadian firefighters
10:00 AM roycroft: if any are available - they're having a horrible fire season again there
10:01 AM roycroft: even newfoundland has had some big wildfires this year
10:01 AM roycroft: which is almost unheard of
10:01 AM roycroft: time to take the car in - bbiab
10:01 AM lcnc-relay: <satiowadahc@> Can confirm. Smoke has been pretty bad this week mid Canadian prairies.
10:08 AM Tom_L: satiowadahc unless you need them you can build with no docs
10:09 AM Tom_L: there are several languages etc to build is probably why
10:13 AM lcnc-relay: <satiowadahc@> Trying to fix a link I made yesterday. Syntax is escaping me here.
10:14 AM lcnc-relay: <satiowadahc@> Even with disabling translations, building the docs alone takes way longer than building the source code
10:27 AM Tom_L: absolutely
10:27 AM Tom_L: that's why there's a no docs switch
10:27 AM Tom_L: and it has change a bit so i'm not sure the syntax now either
10:39 AM Tom_L: who was asking about building arm images the other day?
10:40 AM Tom_L: https://github.com/rodw-au/rpi-img-builder-lcnc
10:41 AM Tom_L: http://linuxcnc.org/docs/stable/html/getting-started/getting-linuxcnc.html#_installing_on_raspbian_12
10:46 AM roycroft: i found a buck converter that is small and affordable
10:46 AM roycroft: it's 12v out, not 24v, but that will be fine
10:47 AM roycroft: 12v is better than 5v :)
10:47 AM Tom_L: in what way?
10:50 AM Tom_L: i used the center tap off one of my transformers to get 24v but you don't have that option
10:54 AM roycroft: going on a comment pcw made on the forum, which makes sense
10:54 AM Tom_L: https://www.ebay.com/itm/141943328732
10:54 AM roycroft: for mechanical switches, 24v is more reliable long-term than 5v
10:55 AM roycroft: i'll translate my experience with 6v volkswagens that i converted to 12v
10:55 AM Tom_L: only small one i've found so far
10:55 AM roycroft: as contacts corrode/oxidize the higher voltage helps maintain continuity, while the lower voltage fails
10:56 AM roycroft: https://www.ebay.com/itm/334838139485
10:56 AM roycroft: that's what i got, and that's all i need
10:57 AM roycroft: and it's a little cheaper than the 24v one you found
10:57 AM Tom_L: i remember a handfull of vehicles with + gnd
10:57 AM roycroft: which i did not see, because i only see listings that ship from the usa
10:58 AM roycroft: i will not play tariff roulette
10:58 AM roycroft: that can be somebody else's game
10:58 AM roycroft: yes, i've had 6v positive ground vehicles
10:58 AM roycroft: the '52 ford pickup with the flathead 6 was that
10:59 AM Tom_L: the ones i can think of were british
10:59 AM lcnc-relay: <.le_potato@> http://gumicsonak.ddns.net/nc/index.php/s/L8W6MWEmZ5sHxZA
10:59 AM lcnc-relay: <.le_potato@> i making my vise spacer
11:00 AM Tom_L: you should make some soft jaws for it
11:01 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Softjaws1.jpg
11:01 AM Tom_L: i use them quite a bit
11:03 AM roycroft: i wonder if i should get a tiny vise for the mini-router
11:03 AM Tom_L: 3" are pretty common
11:03 AM Tom_L: 4" are more useful but harder to find good ones
11:03 AM roycroft: probably not - there's almost no z on that machine, and a vise would hold the work up at pretty much the collet level with the spindle all the way up
11:04 AM Tom_L: i wound up getting a set of stub length drills due to that
11:04 AM lcnc-relay: <.le_potato@> 12" for big pp
11:04 AM roycroft: i'd need like 5mm long drills :)
11:04 AM lcnc-relay: <.le_potato@> Tom_L: I using 6061
11:04 AM Tom_L: machines easier doesn't it?
11:04 AM roycroft: toe clamps and other hold-downs will be fine
11:04 AM lcnc-relay: <.le_potato@> i facemill it
11:05 AM roycroft: and fixtures, if i really need them
11:05 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rue/Can_Holder/A12_New/A12_P2_2.jpg
11:05 AM roycroft: first i need to get it ready to cut chips, though, and i'm dangerously close to that
11:05 AM Tom_L: i use softjaws for stuff like that
11:06 AM Tom_L: using G54 G55
11:06 AM Tom_L: i think...
11:10 AM Tom_L: le_potato, that looks like a 4 flute cutter
11:11 AM Tom_L: on aluminum you're better off with a 2 or 3 flute
11:11 AM Tom_L: 4+ on steel and harder materials
11:12 AM roycroft: indeed, aluminium is soft and gummy
11:13 AM roycroft: give it some space
11:13 AM lcnc-relay: <skunkworks8841@> and some sort of lube really helps
11:24 AM JT-Cave: https://www.amazon.com/MACAVGVKNL-Clamp-Fixture-Tabletop-Adjustable/dp/B0DRYDQYVP
11:33 AM roycroft: wd-40 works really well with aluminium
11:34 AM roycroft: or you can go visit abom's youtube channel and he'll recommend some other lube that costs 9x as much
11:34 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Rustlick1.jpg
11:34 AM Tom_L: like that?
11:35 AM lcnc-relay: <skunkworks8841@> all the big youtubers use ancorlube
11:35 AM roycroft: that looks like a useful clamp, jt-cave
11:35 AM lcnc-relay: <skunkworks8841@> anchorlube
11:35 AM roycroft: probaby, tom_l
11:35 AM roycroft: abom only uses cnc products
11:36 AM roycroft: if it comes in a green can that's probably it
11:36 AM roycroft: oh, that's not it
11:36 AM Tom_L: that'll make ~20-30 gal
11:38 AM roycroft: wd-40 is $28/gallon
11:38 AM Tom_L: likely cheaper than 20gal of wd-40
11:38 AM roycroft: that's for a mister though, isn't it?
11:38 AM Tom_L: either way
11:38 AM Tom_L: that's how i use it
11:38 AM JT-Shop: dish soap works on aluminum
11:38 AM roycroft: but you wouldn't just put it in a spray bottle or brush it on
11:38 AM Tom_L: my but ran it in all his cncs
11:39 AM Tom_L: roy you could
11:39 AM roycroft: it's a continuous lube
11:39 AM roycroft: hmm
11:39 AM JT-Shop: nap time
11:39 AM roycroft: the last gallon of wd-40 i bought was several years ago, and i still have much of it
11:39 AM Tom_L: typically we used oil when brushing
11:39 AM roycroft: on steel, sure
11:39 AM roycroft: but on aluminium wd-40
11:40 AM Tom_L: soap probably works just as well
11:41 AM lcnc-relay: <roguish> kerosene is a good lube/coolant for aluminum..... in a spray bottle
11:42 AM roycroft: yeah, kerosene works well too
11:50 AM lcnc-relay: <.le_potato@> Tom_L: I go slow, 480mm/sec and 1mm feed in
11:52 AM Tom_L: that's just gonna build heat and likely gauld the tool
11:53 AM xxcoder: reminds me of that video where guy used grease as cutting oil for copper
11:53 AM xxcoder: probably could do same for alim
11:53 AM xxcoder: good morning
11:55 AM roycroft: not his retirement grease!
11:56 AM roycroft: he's gonna have to cook up a lot of bacon to replace that
11:56 AM lcnc-relay: <.le_potato@> whops, yes 1mm too much
11:57 AM lcnc-relay: <.le_potato@> 0.5mm good with air
12:01 PM lcnc-relay: <skunkworks8841@> we would mix a bit of kerosene with oil
12:03 PM lcnc-relay: <.le_potato@> should buy emulsion or soap water
12:13 PM roycroft: you put de oil in de kerosene, mix it all up
12:14 PM lcnc-relay: <.le_potato@> kerosene lmao
12:14 PM lcnc-relay: <.le_potato@> and i blow up
12:23 PM rdtsc: if you want a mirror finish on copper, use a sapphire or diamond tool and isopropyl alcohol mist
12:52 PM lcnc-relay: <captainhindsight_.@> Soap water tends to not burn as readily as kerosene
12:54 PM lcnc-relay: <captainhindsight_.@> Same for IPA beer vs IPA (isopropyl alcohol)
12:57 PM lcnc-relay: <captainhindsight_.@> I second that emulsion
01:01 PM * roycroft has finished his morning work task, and thinks it's time to do some classicladder work
01:11 PM fluffywolf: "isopropyl alcohol mist" ... that sounds way too much like a blowtorch to me...
01:20 PM fluffywolf: I'm making a motor mount, of the variety that clamps around the motor body. The middle of it is a 3" diameter hole, for the motor, and it'll be in 1/2" thick aluminum. Rather than turning 3.5in3 of alu into chips with a 1/8" endmill, I want to just profile the circle and leave a 2.75" diameter disc behind. i.e. trepan it. is this insane?
01:20 PM fluffywolf: that's a looooong deep slot cut...
01:23 PM fluffywolf: https://imgur.com/a/RLdR6s3 i.e. this.
01:26 PM Tom_L: no that's not insane. keep the channel clear of chips
01:28 PM Tom_L: precisely how i did this: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Speedhandle1.jpg
01:28 PM Tom_L: make sure to clamp the disk in the middle
01:29 PM Tom_L: not just the perimeter
01:29 PM roycroft: trepanning sounds like the best option
01:29 PM roycroft: well, other than casting and cleaning up
01:29 PM roycroft: but that might be a bit more involved than what you want to do
01:31 PM roycroft: actually, an other option might be to use a slightly undersize hole saw to cut out the disc from the center and a boring head to finish the hole
01:31 PM fluffywolf: my plan was double-stick tape and assuming it won't go too stupid between breaking through and lifting the cutter out.
01:31 PM Tom_L: you'll find out on the very last cut
01:32 PM Tom_L: when it breaks loose
01:32 PM roycroft: tuck a phone book inside your shirt
01:32 PM roycroft: the classicladder editor will not let me edit from my office
01:32 PM JT-Shop: a phone book would be an antique now
01:32 PM roycroft: i may have to go to the console for that
01:32 PM JT-Shop: it doesn't like your office?
01:33 PM roycroft: then use a sears and roebuck christmas catalog :)
01:33 PM roycroft: it may have to do with running stand-alone via an x tunnel
01:33 PM JT-Shop: Uline catalog would work
01:33 PM roycroft: if i run it from within linuxcnc it might work better
01:34 PM Tom_L: not many catalogs are printed anymore
01:34 PM roycroft: yeah, and all you have to do is think about the word "uline" or accidently see it, and you'll be getting catalogs in the mail for life from them
01:34 PM Tom_L: yeah i know
01:34 PM roycroft: and if you ask them to stop sending them they'll send you twice as many
01:35 PM fluffywolf: summit racing keeps sending me pointless catalogs
01:35 PM roycroft: i think uline are just a front for the lumber cartel
01:35 PM Tom_L: i've been getting another catalog for years they said i needed to reply to continue
01:35 PM xxcoder: start building a house out of those catalogues
01:42 PM fluffywolf: Tom_L: that url doesn't want to work for me
01:42 PM fluffywolf: nevermind, retrying again did work.
01:45 PM * fluffywolf directs Tom_L to the bin at the hardware store labeled "thick hardened fender washers"
01:45 PM Tom_L: doesn't take much
01:46 PM Tom_L: just enough to keep it from moving and snapping the bit
01:47 PM fluffywolf: I just mean the totally mangled washer off to the side. heh.
01:48 PM fluffywolf: looking at that rendering, now I want to make the ears thinner than the rest of the part... but freecad has been making me so angry that I don't know if I want to try figuring out how to do that.
01:49 PM Tom_L: i did the whole part with a single program. i wanted to see how it would go. so a bunch of op stops and clamp moves and it worked great
01:49 PM Tom_L: top & bottom
01:49 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Speedhandle_profile.jpg
01:50 PM Tom_L: i made the clamps from scrap left over from building the mill
01:50 PM fluffywolf: yeah, I've got two stops in my plan. I'll start with the edges clamped while it mills out the slots, then move to bolts in the slots so it can cut all the way around the outside of the part. then another stop so I can be ready for manual chip clearing for the trepaning cut in the middle.
01:51 PM Tom_L: when i do that, i generally try if possible to dowel pin at least one point
01:52 PM fluffywolf: I'm going to be having pretty low tool pressure. it's aluminum with an extra long 1/8 endmill. I was tempted to try the whole part with it just double stick taped down. lol
01:52 PM lcnc-relay: <captainhindsight_.@> https://www.ndtv.com/world-news/uline-president-expresses-frustration-over-young-employees-resigning-blames-parenting-8029551
01:53 PM lcnc-relay: <captainhindsight_.@> Another psycho
01:55 PM Tom_L: not entirely wrong though
01:57 PM roycroft: perhaps the "traditional workplace" should value its employees as much as its bottom line
01:57 PM Tom_L: you could formulate an argument for either side
01:58 PM xxcoder: want loyality? maybe be loyal to workers
01:58 PM Tom_L: waiting to see how my kid's work changes now that Bosch owns them
01:58 PM roycroft: that said, helicopter parenting is a significant problem imo
01:58 PM xxcoder: I would say so yeah
01:59 PM Tom_L: i don't see alot changing honestly
02:00 PM * roycroft makes his argument in the middle, and when pressed to take a side picks "splunge"
02:00 PM Tom_L: they are treated well at his place and he likes it
02:01 PM roycroft: i'm not a fan of "everyone is the same" and "participation" medals
02:01 PM roycroft: nor ruthless competition
02:01 PM fluffywolf: bbl, lunch over, back off to work
02:01 PM Tom_L: that it taught early on
02:01 PM Tom_L: everyone is a winner
02:02 PM roycroft: but people do need to learn how to set goals and how to reach them
02:02 PM roycroft: and not just muddle on with life aimlessly
02:02 PM Tom_L: you come in 2nd, you are the 1st looser!
02:02 PM xxcoder: thats good. thats what I meant, company and workers work together, not "workers must be loyal, company can fire them anytime for any reason, and pay very low"
02:02 PM Tom_L: try harder
02:02 PM xxcoder: looser? just re-tighten
02:02 PM Tom_L: :)
02:02 PM Tom_L: you get it
02:04 PM roycroft: and while i do not ascribe value to the particular path that a person takes, i do think people should aspire to better themselves, and act accordingly
02:04 PM roycroft: but you know
02:05 PM roycroft: after you're about 4 years old, you really should not need to be given a gold star if you put your underpants on right, instead of backwards
02:39 PM roycroft: classicladder runs fine when invoked from within linuxcnc, but when invoked stand-alone
02:53 PM lcnc-relay: <roguish> roycroft: check around. ya might find some other ladder logic viewers/editors
03:06 PM roycroft: i'm ok with this
03:06 PM roycroft: i am having an issue though
03:06 PM roycroft: i've built a ladder connection
03:07 PM roycroft: i can go the variables box, and if i click on an output that output is triggered and all is as it should be
03:07 PM roycroft: but i cannot click on an input
03:07 PM roycroft: and when the pin i have tied to the input is enaged (i press the e-stop button) nothing happens
03:07 PM lcnc-relay: <roguish> can't help ya. haven't used ladder for years.....
03:07 PM lcnc-relay: <roguish> you'll figure it out
03:08 PM roycroft: i probably have something that i messed up or omitted
03:08 PM roycroft: yeah, i'm like 90% there
03:08 PM roycroft: it's easier to do this in my office where i have a computer with 3 big displays and can look stuff up while i'm working
03:08 PM Tom_L: http://linuxcnc.org/docs/stable/html/ladder/ladder-examples.html#_external_e_stop
03:08 PM roycroft: as it is, i run to the office, do some research, run back to the studio, make the change, test, run back to the office
03:08 PM roycroft: lather/rinse/repeat
03:08 PM Tom_L: might show something
03:09 PM roycroft: and this is a hal thing, not a classicladder thing, i'm sure
03:09 PM roycroft: yeah, i've seen that page
03:09 PM roycroft: i pasted that link here last night or this morning, even :)
03:10 PM roycroft: and i think i know what's wrong
03:13 PM lcnc-relay: <roguish> think I'm gonna watch a couple South Park episodes this evening......
03:14 PM lcnc-relay: <roguish> ok, ride time...... bbl
03:15 PM roycroft: yeah, it works
03:15 PM roycroft: there's one really good one to watch, roguish :)
03:15 PM roycroft: it just came out two days ago
03:16 PM roycroft: this seems odd to me, but with the ladder you have an input line on the left and an output line on the right
03:16 PM roycroft: you drag objects onto "rungs" and connect them with lines from left to right
03:17 PM roycroft: i had put my input on the far left, adjacent to the input line
03:17 PM roycroft: i moved it over one square to the right, added a line from the input line to the object, and now it works as expected
03:17 PM roycroft: which really seems odd, but it works, so i'll go with that
03:18 PM Tom_L: the example doesn't show the extra line
03:18 PM roycroft: yeah
03:18 PM roycroft: but the video i've been watching does
03:18 PM roycroft: and i tried it and it worked
03:18 PM roycroft: maybe i did something else though, but i don't think so
03:19 PM roycroft: so now i have it controlling the indicators the way i want
03:19 PM roycroft: next i figure out how to have it tell linuxcnc that it's in e-stop mode
03:21 PM Tom_L: is the editor standalone?
03:21 PM lcnc-relay: <travis_farmer@> i wish it was cool enough to work in my shop...
03:25 PM lcnc-relay: <travis_farmer@> i had planned on working in my shop early this morning, but i had a autistic meltdown and things just were not going i my favor...
03:25 PM BorgPipe: https://netpipe.ca/wp-content/uploads/2025/07/logoengrave-rotated.jpeg
03:25 PM roycroft: i can only use the classicladder editor when it's invoked from within linuxcnc
03:26 PM roycroft: travis_farmer: it would be really good for you to find a way to cool your shop off a bit
03:26 PM roycroft: even getting a used fan at the goodwill might be helpful
03:26 PM lcnc-relay: <travis_farmer@> yeah, but it has to e cool enough outside to install the A/C 😉
03:26 PM roycroft: oddly, there is an "estop-routine" signal that gets triggered when i press the e-stop button
03:27 PM roycroft: but i did not provision that signal
03:27 PM roycroft: and have not routed anything to it - i wonder where it comes from
03:27 PM roycroft: it does not seem to trigger anything else, though - linuxcnc does not know it's in an e-stop condition, in spite of that signal being triggered
03:29 PM Tom_L: i have loadrt estop_latch
03:29 PM BorgPipe is now known as Netpipe
03:29 PM Tom_L: addf estop-latch.0 servo-thread
03:29 PM Tom_L: net estop-loopout <= estop-latch.0.ok-out
03:29 PM Tom_L: net estop-loopout => hm2_[HOSTMOT2](BOARD).0.gpio.029.out
03:29 PM Tom_L: net estop-loopout => iocontrol.0.emc-enable-in
03:30 PM Tom_L: and some more
03:30 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/configs/NEW_MILL/new_mill.hal
03:30 PM roycroft: i already have the e-stop input pin assigned to classic ladder
03:31 PM Tom_L: it may need the latch
03:31 PM lcnc-relay: <travis_farmer@> bridge a wire to another input 😉
03:31 PM roycroft: but maybe i can assign an output to estop-loopout
03:31 PM roycroft: that would defeat the point of using classicladder, travis_farmer
03:31 PM Tom_L: the whole of mine is in that hal
03:32 PM roycroft: and would waste a precious input :)
03:32 PM Tom_L: i have 2 buttons and the soft button on axis
03:32 PM -!- #linuxcnc mode set to +v by ChanServ
03:32 PM -!- #linuxcnc mode set to +v by ChanServ
03:33 PM JT-Shop: machinery is similar to boats... you're happy the day you bring it home and your also happy the day it gets a new zip code
03:34 PM xxcoder: lol
03:34 PM Tom_L: and they are likely just as happy
03:35 PM JT-Shop: yup so everyone is happy
03:35 PM xxcoder: they are on first stage while youre at second ;)
03:35 PM lcnc-relay: <travis_farmer@> i would be sad to lose my machine after building it... like losing a child
03:36 PM JT-Shop: I'm glad to let a machine go off after it doesn't need me anymore
03:38 PM JT-Shop: I have but one task left to do today and that's put the 16' trailer away
03:39 PM JT-Shop: so I got rid of a DRO I don't think I'll ever use, a 480v-240v 3 phase transformer, a chep pallet, and a wooden box
03:45 PM roycroft: i need to sell my brew system
03:45 PM roycroft: i loved building it and i loved brewing with it
03:46 PM roycroft: the only sadness i'll have when i sell it, though, is that i'm sure i won't get anywhere near what it's worth
03:46 PM roycroft: and i'll be sellign it at a substantial loss
03:46 PM lcnc-relay: <travis_farmer@> thats always my fear
03:46 PM roycroft: but currently i am paying money every month to store it
03:46 PM JT-Shop: that seems to be the norm
03:46 PM roycroft: so i'm already losing money
03:47 PM roycroft: i have way more money invested in my festool gear than in the brew system
03:47 PM roycroft: and while i have no plans at all on selling any of that, since i bought most of it from the refurb website i could sell it today for at least what i paid for it
03:47 PM roycroft: and the festool annual price increase is coming up
03:47 PM JT-Shop: I sold mine for $200 just to get rid of it
03:47 PM roycroft: and they are also going to add a 20% tariff charge next month
03:47 PM JT-Shop: that guy got one good deal
03:47 PM roycroft: which will drive the price of used gear up even more
03:48 PM roycroft: so i could make a nice profit if i sold it all
03:48 PM roycroft: not many tools appreciate in value like that
03:48 PM lcnc-relay: <travis_farmer@> <-- can see JT as more of a moonshiner than a beer drinker 😉
03:49 PM roycroft: i've thought about parting out the brew system
03:49 PM roycroft: i could probably sell all the sanitary tri-clamp fittings individually for more than i'd get for the whole system
03:49 PM roycroft: but then i'd have to scrap the control panel, and i'd really rather see that have a new home than get scrapped
03:50 PM roycroft: i don't have emotional attachments to things, really, but i put a lot of time and energy and money into that panel, and i think it's a really good panel, and it looks awesome
03:51 PM roycroft: i would be sad to see it scrapped
03:52 PM lcnc-relay: <travis_farmer@> hmmm, i start my colonoscopy prep sunday... thats a lot closer than i was hoping...
04:23 PM JT-Shop: roycroft, any brewing clubs in the area?
04:26 PM xxcoder: would donation to one count as tax writeoff
04:30 PM JT-Shop: I found a 2hp briggs horz shaft motor when I moved the surface grinder
04:30 PM Tom_L: that might be handy for something
04:30 PM JT-Shop: and a piece of wide flange beam it was sitting on
04:31 PM JT-Shop: electric is blinking...
04:31 PM Tom_L: storms in the area?
04:31 PM JT-Shop: nope
04:35 PM JT-Shop: I figure it will take a week to put everything away lol
04:38 PM Tom_L: heh
04:39 PM JT-Shop: I'm so glad my buddy came by this morning to help me load the surface grinder up as I can't see the forks from the drivers seat
04:40 PM Tom_L: yeah i'm not sure how successful you would have been otherwise
04:40 PM Tom_L: alot more dangerous
04:40 PM JT-Shop: it would have taken all day... move an inch get off look lather rinse repeat
04:40 PM xxcoder: I wonder if you could use older cellphone using wifi and "webcam" app and use your current to view it. but yeah less safe
04:41 PM JT-Shop: well you need to look at several places to make sure the forks line up with the grinder
04:42 PM JT-Shop: and I trust his judgment on moving heavy equipment
04:42 PM Tom_L: is he the one you helped slice the big tree?
04:43 PM JT-Shop: no, he works at empire
04:43 PM Tom_L: ahh
04:43 PM JT-Shop: I've been doing work for him for a long time
04:43 PM JT-Shop: did a lot of work for him at revere
05:21 PM JT-Shop: I think it will be an early night for me
05:44 PM roycroft: i am thinking about putting my controller and router on a cart and rolling them into my office while i work on the hal/classicladder configs
05:44 PM JT-Shop: skates are put away...
05:44 PM roycroft: it's getting tiresome running back and forth
05:44 PM roycroft: i cannot get the cart into the office, though, because my printer is blocking the path
05:45 PM JT-Shop: it's easier to work on stuff if you can be comfortable
05:45 PM roycroft: i've been meaning on doing a bit of rearranging the office furniture, and now that the boxes are gone, that might be a good idea
05:45 PM roycroft: yeah
05:45 PM roycroft: things are starting to click, but i still have some basic hal concepts that are not totally clear to me
05:46 PM JT-Shop: hal is pretty straight forward
05:46 PM roycroft: it is, and i'm picking it up fast
05:46 PM roycroft: but i'm not totally there yet
05:46 PM roycroft: and when my machine is on one side of the house and my documentation source on the opposite side, it's not fun working on this part
05:47 PM JT-Shop: yup that sucks
05:47 PM roycroft: if it weren't for the bypass tray it would be easy to move the printer
05:47 PM roycroft: the bypass tray is blocked where it is now anyway, but it's easy to unblock it
05:48 PM JT-Shop: yup time to lock up and call it a day
05:48 PM * JT-Shop is one tired puppy
05:48 PM roycroft: i'm hoping my car is done today
05:48 PM roycroft: i have to go to town tomorrow and sunday both, and i do not want to drive the pickup either time
05:49 PM JT-Shop: is it a front wheel drive car?
05:49 PM roycroft: the cab of the pickup is also still full from the last load i brought up from the old house, and i have to rebuild a shelving unit before i can unload it
05:49 PM roycroft: yes, the car is front wheel drive
05:49 PM Guest1773: You can learn quite a bit about hal using the command line tools like halcmd and halshow
05:49 PM roycroft: i'm using those tools, guest1773
05:49 PM JT-Shop: that could be a lot of work to change the clutch then
05:50 PM roycroft: they have to drop the engine and tranny a bit before they can split them
05:50 PM roycroft: it's a full day job
05:50 PM JT-Shop: halshow is on the axis menut
05:50 PM roycroft: but i got there this morning before they opened, so they were able to get started right away, and they had cleared their schedule for the day to work on my car
05:50 PM Guest1773: halcmd is nice because it has command line completion (it "knows and the signal,component,pin, and parameter names)
05:51 PM JT-Shop: say goodnight Gracie
05:51 PM roycroft: ciaoder
05:51 PM Guest1773: halcmd -kf or halcmd -fk depending on mood
05:52 PM roycroft: this is definitely a small town
05:53 PM roycroft: the repair shop lost my phone number
05:53 PM roycroft: so they just drove over to tell me my car is done
05:53 PM xxcoder: lol. well nice that car is done
05:53 PM roycroft: and when i dropped it off they said they were pretty sure it woudl be done today
05:54 PM roycroft: i responded that i think it's about a 6 hour job
05:54 PM roycroft: it's been 7 hours and 40 minutes, and they take an hour lunch break
05:54 PM roycroft: so i think my estimate was pretty spot on
05:55 PM roycroft: anyway, i'm glad it's done
05:56 PM roycroft: btw, my main problem with hal (and linuxcnc in general) is vocabulary
05:56 PM roycroft: hal is very straightforward to use, except i don't know the names of everything
05:57 PM Guest1773: halcmd show all
05:57 PM roycroft: i know what i need to do, i can understand the internal logic of the software, but i don't know the name of the thing i need to connect to another thing or the name of the function i need to call to do the thing i need to do
05:57 PM roycroft: that is just a list of names
05:57 PM roycroft: i need a dictionary
05:57 PM roycroft: so when i read a name i know what it is
05:58 PM Guest1773: For components/hardware, that's the man page
05:59 PM roycroft: well right now i'm dealing with signals
05:59 PM Guest1773: signal are just wires
05:59 PM roycroft: anyway, should get my money ready and head over to get my car
05:59 PM Guest1773: they could all be named blue_wire_NNNN
05:59 PM Tom_L: alot of signals are self explanatory
05:59 PM roycroft: which will hopefully move fast when it goes *vroom* again
06:01 PM Guest1773: Their names _should_ be chosen to be self explanatory
06:02 PM Tom_L: i meant pins but yeah signals too
06:03 PM Guest1773: Yes, pins have (relatively) fixed names but signal names are arbitrary
06:06 PM lcnc-relay: <skunkworks8841@> some/all? componants can be re-named..
06:06 PM lcnc-relay: <skunkworks8841@> pin wise
06:07 PM lcnc-relay: <skunkworks8841@> what is it called - identity>
06:08 PM Tom_L: never messed with that
06:08 PM lcnc-relay: <skunkworks8841@> names=
06:09 PM lcnc-relay: <skunkworks8841@> me either..
06:09 PM lcnc-relay: <skunkworks8841@> makes it more confusing to me 😉
06:09 PM Tom_L: i have enough trouble keeping track of my own identity
06:13 PM lcnc-relay: <skunkworks8841@> I usually do most of my work in halcmd
06:15 PM roycroft: the old clutch disk was wafa thin
06:15 PM roycroft: like down to the rivets
06:15 PM roycroft: but things are solid now
06:15 PM lcnc-relay: <skunkworks8841@> can they re-surface the flywheel and such? o
06:15 PM roycroft: and they charged me $30 less than the estimate
06:15 PM roycroft: no
06:15 PM lcnc-relay: <skunkworks8841@> nice!
06:15 PM roycroft: those are considered wear parts on this vehicle
06:16 PM roycroft: i see why the clutch is a 100k mile clutch
06:16 PM lcnc-relay: <skunkworks8841@> they replaced the flywheel?
06:16 PM roycroft: it's tiny
06:16 PM roycroft: yes, the flywheel is part of the clutch kit
06:16 PM lcnc-relay: <skunkworks8841@> neat!
06:16 PM roycroft: and i paid probably $500 less than if had taken it to town for the repair
06:17 PM roycroft: not to mention the all-day trip to get it there, all-day trip to retrive it, and probably a week or more of it sitting in the shop before they got around to doing the repair
06:17 PM lcnc-relay: <skunkworks8841@> sounds like a good shop
06:18 PM roycroft: one reason, after i stopped being poor, that i kept doing my own vehicle work was because it was so hard to find a decent mechanic
06:18 PM roycroft: yeah, these guys are pretty good
06:18 PM roycroft: i'm a little concerned because their business registration lapsed a couple years ago and they did not renew it
06:18 PM roycroft: that's probably why they're cash only these days
06:19 PM roycroft: but if they do good work for a good price it's something i can live with
06:19 PM roycroft: anyway, that's done, so now i'll see if i can reorganize the office in a way that i can get my cart in
06:20 PM xxcoder: ok this is weird. I got the bugs bait thingy and tracking is still at cafornia.
06:20 PM roycroft: or i can clear off a section of my desk and set it on the desk
06:21 PM roycroft: that will take like 2 minutes
06:21 PM roycroft: and today's goal is for linuxcnc to know when i've pushed the e-stop button, not to rearrange my office
06:22 PM lcnc-relay: <skunkworks8841@> I sent my watch to chris radek last week using priority mail box.. It never showed in their system.. thankfully chris got it this week
06:22 PM roycroft: i was very pleased earlier when the amber lamp went off and the red lamp went on when i pushed the button
06:22 PM roycroft: i have the pins right and the plc logic right
06:25 PM xxcoder: nice
06:29 PM xxcoder: well 2 baits placed. hopefully it means end of rare fruit flies
06:29 PM lcnc-relay: <skunkworks8841@> I don't know what is about making a computer do physical stuff that is really cool and satisfying...
06:29 PM xxcoder: hvent seen one since I managed to manually kill one yesterday but yeah
06:29 PM xxcoder: skunk lol indeed.
06:32 PM roycroft: has anyone here used eneloop pro battries?
06:32 PM roycroft: i'm trying to figure out how they make sense
06:32 PM lcnc-relay: <skunkworks8841@> I have not
06:33 PM roycroft: standard aaa eneloops are 850mah, and can be recharged 2100 times
06:33 PM roycroft: the pros are 980mah, and can be recharged 500 times, and cost more than 2x as much as the standard
06:34 PM roycroft: seems the standard ones give a lot more total life ah than the pros by a factor of about 3-1/2, for half the cost
06:34 PM roycroft: with the drawback of having to be recharged slightly more often
06:36 PM roycroft: i need another power distribution block for the cnc controller, and need to pad the order to $35 to get free shipping, so i was looking for stuff i need, and i'm really low on aaa batteries
06:48 PM lcnc-relay: <pink_vampire@> I'm looking for a recommendation for an endmill for doing parting operation in "wood" (particle board)
06:48 PM lcnc-relay: the spindle is 200W 48V ER11
07:12 PM Tom_L: too small and you'll break it
07:12 PM Tom_L: ideally you want one with geometry for wood
07:13 PM Tom_L: i'm guessing the board will be abrasive so i'd suggest carbide
07:13 PM Tom_L: since it's got alot of glue in it
07:13 PM roycroft: yeah, having the controller in my office is nice
07:14 PM Tom_L: how thick is the particle board?
07:14 PM roycroft: what do you mean by "parting" in this context?
07:14 PM * roycroft thinks of parting as a yahtzee on something round in the lathe
07:14 PM Tom_L: i use endmills sometimes to 'cut' aluminum to length since i don't own a decent cutoff saw
07:15 PM Tom_L: that's how i interpreted it knowing it was a router/mill
07:16 PM roycroft: but plywood is generally largeish sheets
07:16 PM Tom_L: https://www.amazon.com/125-FLUTE-LONG-LENGTH-CARBIDE/dp/B07DJY3NV1
07:16 PM roycroft: or particle board
07:16 PM Tom_L: dunno if those are any good or not
07:16 PM Tom_L: 3/4 loc it looks like
07:17 PM Tom_L: which is alot for a .125 em
07:17 PM Tom_L: 4 flute
07:18 PM Tom_L: https://shop.carbide3d.com/products/102-125-end-mill-cutter
07:18 PM roycroft: and without context, i'd recommend a solid carbide 1/8"/3.2mm spiral upcut router cutter for machining particle board
07:18 PM Tom_L: 2 flute .500 loc
07:18 PM roycroft: and not a standard end mill made for metals
07:20 PM Tom_L: typically wood cutters use a low helix angle don't they?
07:20 PM Tom_L: along with other geometric changes in the cutting edge
07:21 PM roycroft: yes
07:21 PM roycroft: so i'm struggling with something
07:21 PM roycroft: my mouse on my imac will access all three displays on the imac
07:22 PM roycroft: but i keep trying to move it over to the display for my cnc controller, and it's not going there
07:22 PM Tom_L: i never could get used to that
07:22 PM roycroft: i can't seem to remember to use the other mouse
07:22 PM Tom_L: i have a pile of em just for that
07:23 PM roycroft: the problem is with my braine
07:23 PM roycroft: brain
07:23 PM Tom_L: i do have to swap some when using the rpis
07:23 PM roycroft: not with the correct number of pointing devices
07:23 PM Tom_L: that's why i use a single screen. i never could get used to multiple
07:23 PM Tom_L: but have multiple PCs for docs etc
07:23 PM roycroft: i have no problem with multiple screens as long as they're connected to the same computer
07:24 PM roycroft: but now i have this other screen
07:24 PM xxcoder: 2 screens forever for me
07:24 PM roycroft: and it's just as big as the main ones, and also 4k like the main ones
07:24 PM roycroft: so it looks like it should belong to my imac
07:24 PM roycroft: but that's not the real problem
07:24 PM xxcoder: second is almost always irc, but also used for reference browser when I need to be able to see it and do something at same time
07:25 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/cad-station.jpg
07:25 PM roycroft: there is an estop-loopback signal that is triggered by pushing the e-stop button in the axis gui
07:25 PM Tom_L: yessir
07:25 PM roycroft: i can't find a way to map that to a classicladder pin
07:26 PM roycroft: and i still don't see how linuxcnc knows it's in e-stop mode
07:27 PM roycroft: when estop-loopback is triggered i can set motion-enable and joint-0-enable, amongst other signals
07:27 PM roycroft: and when i press the gui e-stop button it triggers those other signals off
07:28 PM roycroft: i want it to behave exactly like the physical e-stop button
07:28 PM roycroft: it seems i can wire up pins in classicladder, but i'm not seeing how to wire up signals
07:29 PM roycroft: and the wifi is all but useless in my office
07:29 PM Tom_L: http://paste.debian.net/1387859/
07:29 PM roycroft: so no copy/paste to it
07:29 PM Tom_L: the whole of my estop loop
07:29 PM Tom_L: alot of it happens in iocontrol
07:30 PM Tom_L: i have 2 physical switches and a soft switch in axis
07:30 PM roycroft: i may have a second switch eventually
07:30 PM Tom_L: one is on my pendant
07:31 PM roycroft: yeah, if i get a second one it would be on a pendant
07:31 PM roycroft: so you're using the estop-latch function
07:32 PM Tom_L: http://linuxcnc.org/docs/stable/html/man/man1/iov2.1.html
07:32 PM Tom_L: iocontrol.0.user-enable-out
07:32 PM Tom_L: (Bit, Out) FALSE when an internal estop condition exists.
07:32 PM Tom_L: iocontrol.0.emc-enable-in
07:32 PM Tom_L: (Bit, In) Should be driven FALSE when an external estop condition exists.
07:33 PM Tom_L: also
07:33 PM Tom_L: http://linuxcnc.org/docs/stable/html/man/man1/halui.1.html
07:33 PM Tom_L: search estop
07:33 PM Tom_L: halui.estop.activate bit in
07:33 PM Tom_L: halui.estop.is-activated bit out
07:33 PM Tom_L: halui.estop.reset bit in
07:34 PM roycroft: i'm getting 65000ms pings to my controller from my imac
07:34 PM roycroft: that's not good
07:34 PM roycroft: ok, so those iocontrol pins may be the ticket
07:34 PM Tom_L: that or the halui ones yes
07:35 PM Tom_L: those are the main 'user interface' functions
07:35 PM Tom_L: and the latch
07:36 PM Tom_L: i just used hal logic instead of ladder
07:37 PM roycroft: i'm into the ladder thing now
07:37 PM Tom_L: just an or gate for the 2 inputs
07:37 PM roycroft: so i'm going to keep going with that for now, at least
07:37 PM roycroft: i think it will be better long-term - it gives me more flexibility
07:37 PM Tom_L: i'm not trying to sway you either way, that's just how i did it
07:37 PM Tom_L: either one would work
07:39 PM Tom_L: put the loadrt estop_latch near the top of the hal file
07:39 PM Tom_L: it will get loaded first
07:41 PM roycroft: it's loading before any of the classicladder stuff
07:42 PM Tom_L: just saying, sometimes load order matters with lcnc
07:42 PM roycroft: and i've determined that iocontrol.0.emc-enable-in is what is tied to the e-stop button in the axis gui
07:42 PM roycroft: but it's already linked to estop-loopback, so i can't use it
07:43 PM Tom_L: could be, it's been a while since i went over that stuff
07:43 PM Tom_L: why not?
07:43 PM Tom_L: connect the net
07:43 PM Tom_L: net x estop.myestop
07:44 PM Tom_L: net x => latch
07:44 PM Tom_L: net x => ladder
07:45 PM roycroft: net estop-loopback iocontrol.o.emc-enable-in <= iocontrol.0.user-enable-out
07:45 PM roycroft: that is part of the stock hal file
07:45 PM Tom_L: did you cut paste that?
07:45 PM Tom_L: if so there's a typo
07:45 PM Tom_L: .o.
07:45 PM Tom_L: .0.
07:45 PM roycroft: no, because the machine is not on the network reliably
07:45 PM Tom_L: ok
07:45 PM roycroft: so i probably typoed something :)
07:46 PM roycroft: but you can figure out what it's supposed. to be
07:46 PM Tom_L: just makeing sure
07:46 PM roycroft: o vs 0
07:46 PM roycroft: maybe it's because the display is right on top of the rpi that the wifi is wonky
07:46 PM * roycroft moves it
07:47 PM Tom_L: iocontrol.0.user-enable-out would go to it's own net
07:47 PM roycroft: it's the display that is causing the interference
07:48 PM roycroft: because when i moved it the hdmi cable disconnected and i was suddenly getting 3ms pings
07:48 PM roycroft: when i plugged it back in i got 60000ms pings again
07:48 PM xxcoder: fun emi
07:48 PM roycroft: so i just need to find a place where it does not interfere
07:48 PM roycroft: yeah, and it works fine in the studio
07:48 PM roycroft: but the wifi router is in the studio
07:50 PM Tom_L: estop-latch.0.fault-in may be the one that tells lcnc there's an estop
07:50 PM Tom_L: my buttons go to that i believe
07:50 PM Tom_L: thru the or gate
07:51 PM Tom_L: ln 11-12
07:51 PM roycroft: aah, i can ssh to the controller now
07:51 PM roycroft: having moved the display far far away - it's a good thing it's 27"
07:52 PM Tom_L: estop-latch.0.ok-out would likely be the reset signal
07:52 PM Tom_L: and it goes to iocontrol.0.emc-enable-in
07:52 PM roycroft: i'm not sure i need the estop-latch function, especially since i'm doing my own thing
07:53 PM roycroft: i just need all the pins
07:53 PM Tom_L: as long as you latch it and have a separate reset
07:54 PM roycroft: i should be able to do all that with classicladder logic
07:54 PM Tom_L: i'm sure you can
07:54 PM Tom_L: i've just never messed with it
08:03 PM Tom_L: also
08:03 PM fluffywolf: wow, we were talking about classicladder when I left for work, and still talking about it when I get back! lol
08:03 PM Tom_L: https://forum.linuxcnc.org/47-hal-examples/25861-external-e-stop
08:04 PM Tom_L: and alot of other stuff in betweeen
08:04 PM Tom_L: roycroft, ^^
08:04 PM roycroft: i've seen that, thanks
08:05 PM Tom_L: that's basically what i did but have more buttons
08:12 PM fluffywolf: https://www.youtube.com/watch?v=3rPKZXmBueM youtube suggested this... so far it's seeming surprisingly decent for a video with 2000 views.
08:25 PM Netpipe: sweet i dont have to convert bmp's to 1 bit grayscale to make it work with potrace just needed to convert it to pbm format
08:30 PM roycroft: it's a brand new video, and the guy has 564k subscribers, so the views will probably go up by an order of magnitude or more over the weekend
08:58 PM xxcoder: roycroft: just remembered that theres that program that seamless transfers mouse control as you reaches edge, to seperate computer or whatever
08:58 PM xxcoder: by stardock I think?
08:58 PM xxcoder: https://www.stardock.com/products/multiplicity/ yep
09:01 PM xxcoder: hmm basic and second tier buttons is broken so I cant even see pricing for those lol
09:03 PM xxcoder: deskflow is free open source
09:09 PM roycroft: i'll just have to remember to use the other mouse
09:09 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/uKJwcnQcRQKqqWUP9
09:10 PM roycroft: when i had my other imac in the office it was no problem, as i was using both of them on a daily basis, switching back and forth
09:10 PM Tom_L: child labor
09:10 PM roycroft: but this cnc controller just moved in, so it takes some getting used to
09:10 PM Tom_L: i bet he's having fun
09:11 PM lcnc-relay: <skunkworks8841@> He put on a long sleeve shirt..
09:11 PM roycroft: i like the welding trousers
09:11 PM roycroft: i'm assuming they are not made of synthetic fabric
09:11 PM roycroft: so that we don't have to ring up child protective services :)
09:12 PM roycroft: xxcoder: that software is windows-based
09:12 PM roycroft: my machines in the office right now run macos and linux
09:13 PM xxcoder: stardock definitely. I forgot that stardock is purely windows company.
09:13 PM roycroft: well, there's a windows machine - my cad workstation - but that's in another part of the room
09:13 PM xxcoder: deskflow might be work
09:13 PM roycroft: hopefully this machine will be back in the studio tomorrow
09:13 PM roycroft: it's only here while i figure out the e-stop logic
09:22 PM xxcoder: yeah
09:29 PM lcnc-relay: <skunkworks8841@> they are cotton pajama pants
09:49 PM roycroft: good
09:49 PM roycroft: a lot of those are synthetic
09:49 PM roycroft: i figured you would know better :)
09:50 PM * roycroft notes the smilie he used above
10:05 PM wolfluffyf: grrr. I'm replacing a 3" diameter motor with a 3" diameter motor. The old one measures 3.0000. The new one measures 2.9895. more than 10 thous off! I wonder what clamping range my clamp has...
10:07 PM wolfluffyf: I guess motors shouldn't be assumed to be precision fits, and the first one was probably the exception not the norm.
10:07 PM wolfluffyf: should I make my clamp undersized, or make it for 3 even? lol
10:11 PM Tom_L: can you clamp it .010?
10:16 PM * wolfluffyf is too tired to math
10:16 PM pcw---home: shim
10:16 PM Tom_L: .010 on the D would be more on the circumference ya know
10:18 PM wolfluffyf: machining undersized seems like the safe option. I can always run some emery cloth around if it I later want to use an on-dimension motor.
10:29 PM roycroft: your clamp should be adjustable
10:30 PM roycroft: you should bore it a couple thousandths oversize, cut a slit in it, and squeeze it tight once you insert the spindle
10:31 PM xxcoder: if it cant be perfect, make it adjustable
10:32 PM roycroft: it's going to take a lot of emory cloth to open the bore by 0.010"
10:32 PM ywolflufff: grrrr, stupid internet...
10:32 PM ywolflufff: https://imgur.com/a/RLdR6s3 is my current design
10:32 PM roycroft: when i got the router lift for my router table the spindle was too loose - it was made to hold a router, not an 80mm spindle
10:33 PM roycroft: i ended up wrapping some shim stock around the spindle
10:33 PM roycroft: i think it was 0.010" thick or something similar - it's been years, and i forget exactly how much
10:33 PM roycroft: but at any rate i was able to tighten it down once i had the shim stock in place
