12:53 AM Deejay: moin
02:18 AM pere: I must admit, after this weekends session with a Mazak running LinuxCNC, that it is amazing the speed in which an industrial CNC can turn a workpiece into scrap metal. :)
02:20 AM XXCoder: lightining fast
02:28 AM travis_farmer[m4: Morning ☕️
02:35 AM Loetmichel: pere: hehe, i know that feeling. and its ALWAYS one of the last actions that does that.
02:36 AM Loetmichel: "ups, there i forgot a g0z +50 before g0xy... aaand another nearly finised part for the scrap bin!"
03:17 AM ritu[m] is now known as ritu72470[m]
03:22 AM Guest75 is now known as Jymmmmm
03:25 AM Jymmmmm: Ok, this.is.cool.... Called VENTOY It allows you to take a usb stick, drop ISO's on it, and then gives you a menu which iso to boot from... no more imaging ISO's https://www.youtube.com/watch?v=9QU1EjQ48H0
03:26 AM XXCoder: interesting
03:31 AM NorthOwl[m] is now known as NorthOwl4619[m]
03:31 AM NorthOwl4619[m]: Hello! So Debian Bookworm is released, how's stability of LinuxCNC 2.9 snapshot which comes in the official repos? Is it stable enough to use in production? I want to make it default option for customer machines but I'm afraid to get in trouble in case if some major bugs are present.
03:32 AM pere: NorthOwl4619[m]: I doubt anyone can measure that for you. I use a 2.9 snapshot myself, but can not speak for any other setup.
03:34 AM pere: NorthOwl4619[m]: <URL: https://github.com/LinuxCNC/linuxcnc/issues?q=is%3Aissue+is%3Aopen+label%3A2.9-must-fix > might provide an interesting data point, but I assume you already had a look at that list.
03:34 AM NorthOwl4619[m]: I just want to hear some other opinions. Of course I gonna do testing myself on multiple machines, but broader sample is always good.
03:35 AM NorthOwl4619[m]: TY I'll look
03:36 AM Jymmmmm: XXCoder Yeah, I have a device that looks like a 2.5" encloure that does the same thing, but this is universal
03:36 AM Jymmmmm: Good for testing various things easily
03:36 AM XXCoder: yeah
03:37 AM pere: NorthOwl4619[m]: what kind of machines are you selling?
03:38 AM NorthOwl4619[m]: mills mostly
03:40 AM travis_farmer[m4: i use 2.9 pre1, on Debian Bullseye. the only instability i found is sue to my own errors
03:40 AM travis_farmer[m4: "due" not "sue", LMAO
03:41 AM Jymmmmm: Hands travis_farmer[m] ANOTHER loaded gun... you know, so you can shoot yourself in your other foot.
03:41 AM pere: I run on bookworm myself, and it has worked great so far. had a snag with opengl related stuff, but a workaround was added to linuxcnc.
03:43 AM NorthOwl4619[m]: yeah, same thing with opengl, got me worried a bit, but seems to work fine after swithing on newer revision
03:44 AM NorthOwl4619[m]: travis_farmer ty, glad to hear that
03:46 AM pere: Anyone here using FreeCAD Path? Is it supposed to emit G2 or G3 for circles with LinuxCNC?
04:00 AM mrec: pere: yes
04:01 AM pere: hm, mine did not when I created a simple cylinder. :(
04:14 AM mrec: it depends what you're doing
04:16 AM mrec: however it's also doing discretize when creating paths, searching the code yields several positions where it does a G2/G3
04:16 AM mrec: discretize = when there's a curve it's chopping the curve into segments
04:18 AM mrec: returning points. The distance is hardcoded
04:19 AM danielh4711[m] is now known as danielh47110[m]
04:24 AM pere: mrec: I created a new body using a sketch with a cirle padded to 1 cm, created a new path job with a square stock, and asked for adaptive clearing. the resulting g-code did not use g2 or g3.
04:27 AM mrec: pere: adaptive clearing is not circle cutting
04:27 AM mrec: cutting/milling
04:28 AM mrec: it's trochoidal milling
04:28 AM mrec: if you mill from inside out you'll get a spiral
04:46 AM Tom_L: morning
04:52 AM Jymmmmm: Hola Tom_L
04:53 AM Jymmmmm: Tom_L this.is.cool.... Called VENTOY It allows you to take a usb stick, drop ISO's on it, and then gives you a menu which iso to boot from... no more imaging ISO's https://www.youtube.com/watch?v=9QU1EjQ48H0
05:14 AM pere: mrec: I expected at least a cirle for the final pass around the cylinder...
05:18 AM JT-Cave: morning
05:19 AM mrec: pere: it's not that advanced
05:21 AM pere: mrec: so what is using cirle cutting in FreeCAD Path?
05:24 AM rmu: pere: profile operation of a cylinder created from extruded circle creates G2
05:40 AM JT-Cave: rooster just crowed
06:03 AM * travis_farmer[m4 uploaded an image: (869KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/VbnYveAFziRdDeCEqZQrfjjh/weather_2023-06-26.png >
06:03 AM travis_farmer[m4: rain, rain, rain...
06:10 AM JT-Cave: none in sight
06:13 AM travis_farmer[m4: weather looks rough in tornado alley...
06:33 AM Loetmichel: travis_farmer[m4: over here its like 33°C and steely sky. Not a single cloud... and this office is even hotter thanks to that full size server rack in the corner. I'm melting!
07:08 AM * JT-Cave has to get rocking this morning... departure time 8:30am or so
10:21 AM Scopeuk: can see it on the live satalites https://zoom.earth/maps/satellite/#view=43.1,-28.2,5z
10:46 AM perry_j1987: what are we looking at
10:47 AM perry_j1987: looks like the area they found that pyramid underwater off coast of portugal heh
10:51 AM Scopeuk: the more consistent darker grey is a chunk of the smoke cloud from the Canadian wild fires making its way over to Europe
11:08 AM CaptHindsight[m]: unterhausen: why do some machines almost work since they only use PLC's vs move up to PC's for control? Is anything beyond ladder logic not permitted by some council or administration?
11:19 AM roycroft: smoke on the water
11:20 AM roycroft: poutine's better than fries
11:28 AM skunkworks[m]: CaptHindsight: the crew here uses mostly plc's... For motion and all. it is crazy.
11:28 AM skunkworks[m]: They have gotten into more motion controllers - but still hardware based..
11:29 AM skunkworks[m]: Treo?
11:33 AM * travis_farmer[m4 uploaded an image: (5550KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/hRRaHdfgCBGipgNWLWVcOXyl/20230626_102227.jpg >
11:33 AM travis_farmer[m4: tried a laser burn on my machine from a vector image, and it came out far better than my attempt with a raster image.
11:45 AM roycroft: are you taking good care of your other eye?
11:46 AM travis_farmer[m4: wasn't in the shop after i hit go, and any time i checked from afar, was with my crappy safety glasses on
12:29 PM Unterhaus_ is now known as Unterhausen
12:29 PM Unterhausen: I think that plc's are supposed to be deterministic, so it's probably easier to sell. Maybe due to UL?
12:30 PM Unterhausen: Technically we're all supposed to get our hobby machine tools ul certified
12:30 PM Unterhausen: certainly would be the case for commercial machines
12:39 PM roycroft: UL certification of your hobby machine, assuming you have no employees operating it, would be strictly between the machine owner and the machine owner's insurance company
12:40 PM Loetmichel: travis_farmer[m4: is that a co2 laser or a diode one?
12:40 PM Loetmichel: for co2 even normal "collison" safety glasses are good enough because they are nearly 100% opaque at 10030nm
12:41 PM Loetmichel: 10600nm, sorry
12:45 PM ZincBoy[CAON][m]: At least in Canada, you can get a special inspection (ESA) for equipment that does not have a ULc or CSA certifcation. We do this at work all the time because no one is going to get certification for equipment that sell in quantity 10 world wide. Costs a few hundred and the main things you normally need to do are replacing the circuit breakers/fuses with certified ones and making sure the grounding is appropriate.
12:46 PM travis_farmer[m4: it is a diode 445nm
12:47 PM Loetmichel: ok, then you are out of luck with normal acrylic or PC "glass" safety googles
12:48 PM travis_farmer[m4: these are stated for laser, with 445nm in the range, but not certified. hence why i still view from afar
12:49 PM Loetmichel: good decision i would say :)
12:55 PM jpa-: Loetmichel: with CO2, while normal glasses filter the laser beam well, there is still the tiny bright dot of burning material that can be harmful to stare at
12:56 PM Loetmichel: jpa: acrylic and PC are even better at filtering far IR.
12:57 PM roycroft: all you have to do is apply plenty of pumpkin-colored makeup to your face, and you can safely stare at anything
12:57 PM Loetmichel: btw: from experience: it takes only a few ms to burn a nice 3mm diameter black dot on skin if you reach into the beam of a 40W co2. Even Before collimating. BTDT :)
12:58 PM Loetmichel: (note to self: dont try again to move the head of the lasercutter by hand and pressing the "laser test" button!)
12:59 PM * travis_farmer[m4 would never reach into the beam ;-)
12:59 PM Loetmichel: ... at least i noticed immediatly!
12:59 PM Loetmichel: :)
01:35 PM JT-Cave: lunch minute
01:35 PM roycroft: you need two laser test buttons that must be pressed simultaneously
01:35 PM roycroft: neither of which is a foot switch
01:35 PM CaptHindsight[m]: at least 10 ft apart
01:36 PM Tom_L: ^^
01:36 PM Tom_L: was gonna say
01:36 PM roycroft: maybe you need two laser test buttons and two laser test foot switches
01:36 PM travis_farmer[m4: LMAO :-)
01:36 PM * Tom_L gives travis_farmer[m4 a white walking stick
01:37 PM travis_farmer[m4: my eyes are just fine, Tom_L :-P
01:37 PM Tom_L: for now
01:37 PM CaptHindsight[m]: and with challenge response cyber security that calls you at a 2nd number to authorize you with a 23 digit access code to the test switch
01:38 PM Tom_L: apple is gone, lunch is over
01:39 PM CaptHindsight[m]: never use test switches that may be duck taped to their ON position
01:39 PM CaptHindsight[m]: duct tape is ok
01:41 PM CaptHindsight[m]: https://cbsarcsafe.com/wp-content/uploads/2013/09/PPEZ-in-action.png
01:41 PM Loetmichel: roycroft: i think a safety switch on the lid of the cutter would do.
01:41 PM Loetmichel: something the chinese seem to consider "unneccessary"
01:42 PM Loetmichel: CaptHindsight[m]: HV gear or radiation gear? cant really tell
01:43 PM CaptHindsight[m]: https://cbsarcsafe.com/products/handheld-racking-tool-ppe-z/
01:44 PM Loetmichel: ah, "switch winder"
01:44 PM CaptHindsight[m]: https://www.galvinpower.org/wp-content/uploads/2021/08/how-to-tell-if-a-circuit-breaker-is-bad.jpg
01:44 PM Loetmichel: hehe, that looks kinda familliar.
01:48 PM CaptHindsight[m]: lots of breakers in such a small space
01:48 PM CaptHindsight[m]: there should be rules for this kind of thing
01:49 PM CaptHindsight[m]: Loetmichel: are you facing another unusually hot for your part of the world summer?
01:49 PM Loetmichel: yeah, plus the server rack in my office. its kinda like sauna at work at the moment
01:52 PM Loetmichel: for that breaker box: that would probably up to code in germany. But as my old Elektrician boss said more than once: "I'd rather pay for a new breaker every now and then than you not torqueing the terminal screws enough."
01:52 PM CaptHindsight[m]: Loetmichel: do you still have the peltier cooled suit from a few years back?
01:52 PM Loetmichel: He knew why. As the saying goes "a german electrician is with one foot in the grave and with the other in jail!"
01:52 PM Unterhausen: roycroft: I have heard of code enforcement requiring ul listing on hobby machines when someone did wiring
01:53 PM Unterhausen: If you have one foot in the grave, it's a lot harder to get shocked
01:53 PM Loetmichel: the suit was not peltier cooled but with a little glow engine converted to butane and a compressor. And no, the gas tank exploded.
01:54 PM Loetmichel: while i was working on it.
01:54 PM Loetmichel: and it wasnt a few years back but a few decades :)
01:55 PM Loetmichel: early 90s to be precise
01:56 PM CaptHindsight[m]: they should plumb workstations with tap water with quick connect fittings
01:56 PM CaptHindsight[m]: then you can wear a cooling vest, it would hardly need any flow
01:57 PM * JT-Cave smells a nap in the near future
01:57 PM CaptHindsight[m]: I found that even a water filled pad to sit or lay against makes a big difference when it's >30C
01:57 PM Loetmichel: hmm, i think its cheaper to just install an A/C in the office. The server room and the measurement chamber have.
01:57 PM Loetmichel: offices (and the backup server rack) have not. "just people" :)
01:58 PM CaptHindsight[m]: Loetmichel: what is the avg electrical rate per KWh there?
01:58 PM Loetmichel: about 0.50 eur per kWh
01:59 PM CaptHindsight[m]: oh that's 2-3X what we pay here
02:01 PM CaptHindsight[m]: I thought that solar kept the rates lower there
02:01 PM Tom_L: put a windmill in your back yard
02:02 PM Loetmichel: CaptHindsight[m]:
02:02 PM Loetmichel: Grundpreis (brutto)
02:02 PM Loetmichel: 9,22 €/Monat
02:02 PM Loetmichel: Verbrauchspreis (brutto)
02:02 PM Loetmichel: 34,99 ct/kWh
02:02 PM Loetmichel: grundpreis is "meter rent"
02:03 PM Loetmichel: just google it for the local utilities here
02:03 PM Loetmichel: googled
02:04 PM CaptHindsight[m]: Tom_L: just do what Texas does
02:11 PM pere: is it possible to see somewhere in LinuxCNC what the current value set by g43.1 is?
02:19 PM CaptHindsight[m]: https://linuxcnc.org/docs/2.6/html/gcode/gcode.html#sec:G43_1
02:20 PM CaptHindsight[m]: you could keep track of it and have it show up in the GUI
02:22 PM pere: CaptHindsight[m]: not sure what you are trying to show me there? I've read it multiple times, and still have not found a way to extract the current value. is there some # style variable I have missed?
02:27 PM CaptHindsight[m]: pere: i can think of a few ways to keep track of it, add a unique M code after that line to trigger an alert when that line is run, reading that g43.1 will give you the current value
02:36 PM abcurrie[m] is now known as abcurrie0[m]
02:37 PM skunkworks[m]: wouldn't it be here..
02:37 PM skunkworks[m]: http://linuxcnc.org/docs/stable/html/gcode/overview.html#sub:numbered-parameters
02:38 PM skunkworks[m]: 5401-5409 - Tool Offsets for X, Y, Z, A, B, C, U, V & W. Volatile.
02:39 PM pere: skunkworks[m]: I understood it to be the values from the tool table, not the value set by G43.1?
02:39 PM skunkworks[m]: easy to test...
02:39 PM skunkworks[m]: I read it as current tool offset..
02:40 PM CaptHindsight[m]: Note
02:40 PM CaptHindsight[m]: G43.1 does not write to the tool table.
02:40 PM skunkworks[m]: oh. oops
02:41 PM CaptHindsight[m]: it OK!
02:43 PM pere: Tried this, did not show any change.
02:43 PM pere: (print, tool offset z #5403)
02:43 PM pere: G43.1 Z0.1234
02:43 PM pere: (print, tool offset z #5403)
02:44 PM skunkworks[m]: did you apply the tool lenght?
02:44 PM pere: the value was fetched from the tool table, not the current offset.
02:44 PM skunkworks[m]: g43
02:45 PM skunkworks[m]: never mind
02:45 PM pere: skunkworks[m]: not at first. did not make a difference.
03:04 PM JT-Shop: wow Thursday high is 105°F here
03:06 PM travis_farmer[m4: highest i am getting on the 7-day forecast is 77F
03:06 PM travis_farmer[m4: with rain, still :-(
03:07 PM JT-Shop: LOL someone is trying to sell a 8hp Briggs motor when they give them away all the time
03:07 PM travis_farmer[m4: lol
03:07 PM JT-Shop: Briggs has a small engine plant here
03:07 PM travis_farmer[m4: "good luck with that...", eh?
03:20 PM roycroft: it's going to get hot here later this week too
03:21 PM XXCoder: fun
03:33 PM Tom_L: JT-Shop, a lunchpail briggs?
03:45 PM roycroft: https://roycroft.us/BowTies/BowTies2.jpeg
03:46 PM roycroft: that's my first attempt at using the shaper origin
03:46 PM roycroft: fortunately it's the underside of the counter, and won't show
03:46 PM roycroft: the show side should turn out much better
03:47 PM XXCoder: it looks great
03:47 PM roycroft: it's acceptable
03:47 PM XXCoder: though one end is misaligned?
03:47 PM roycroft: i haven't trimmed that edge yet
03:47 PM XXCoder: or is it just bowtie first then ah ok
03:48 PM roycroft: i jointed the two slabs before the glue-up
03:48 PM roycroft: but since one edge is a live edge, i could not cut them to width
03:48 PM roycroft: i had to line up the live edge as best i could when gluing up, and then cut the back edge after
03:49 PM JT-Shop: Tom_L, ?
03:49 PM roycroft: the grain doesn't line up well either, but i only had the two slabs, and they were already too narrow, so i did the best with what i had
03:49 PM JT-Shop: that's all you can do
03:50 PM roycroft: so the bow ties did not fit when i cut the recesses
03:50 PM roycroft: the "usual" origin way is to redo the recess cut 0.005" oversize
03:50 PM roycroft: which i was dubious about, and that's why there are some gaps
03:51 PM JT-Shop: I figured you would hand fit the holes to the bow ties...
03:51 PM roycroft: i think for the top i'll cut to exact size, chamfer the bow ties slightly, and if they still don't fit well, shave them down by hand until they did
03:51 PM roycroft: the shaper community seem to like to cut oversize recesses
03:52 PM roycroft: but, you know, this is the typical crowd who think in terms of fractional inches, and think that thousandths are for machinists
03:52 PM roycroft: 0.005" to me is a *huge* gap in a joint
03:52 PM roycroft: but i tried it their way the first time
03:53 PM roycroft: on something that won't ever be seen
03:53 PM roycroft: and it's really not horrible, for the most part
03:53 PM XXCoder: its good to see how others do it first
03:53 PM XXCoder: sometimes theres hidden stuff behind it
03:54 PM roycroft: if you look at the lower right corner of the top bow tie, you see a little gap in the recess right by the corner
03:54 PM roycroft: that's where my shaper tape view became unhealthy and the origin lost its position
03:54 PM roycroft: as i said yesterday, i was very frugal with my use of shaper tape
03:54 PM roycroft: another strip of tape would have prevented that
03:55 PM roycroft: and if i had paid better attention i'd have notice that the shaper tape health was deteriorating
03:55 PM roycroft: when that happens, one can just add more tape to the field, rescan, and continue cutting
03:55 PM roycroft: but i did not notice until it was too late
03:56 PM XXCoder: reminds me of that saying that experence correrates with number and cost of scraps
03:56 PM roycroft: yes
03:57 PM roycroft: and what i did on my first go is acceptable
03:57 PM roycroft: commercial furniture often has sloppier joinery than that
03:57 PM roycroft: but it's still not good
03:57 PM XXCoder: eye of beholder I guess
03:58 PM XXCoder: your joinery looked quite good to me
03:58 PM Tom_L: JT-Shop, the guy selling the briggs... did he bring it home in his lunchpail?
04:06 PM JT-Shop: ah, prob not... briggs will give engines away to employees and to things like benefit rides. I have a couple of new engines in their boxes from poker and benefit rides...
04:07 PM Tom_L: horizontal or vertical shaft?
04:07 PM Tom_L: they probably don't make as many horizontal
04:18 PM JT-Shop: all vertical shaft here
04:18 PM JT-Shop: all have the same base plate
04:18 PM JT-Shop: crank's and other things are different
04:20 PM Tom_L: do they make any with a steel sleeve?
04:23 PM JT-Shop: IIRC they make a cast iron sleeve on some... but most are aluminum
04:29 PM perry_j1987: welp i did it... rammed the stylus of this touch probe lol
04:29 PM perry_j1987: bent over in a nice 90 degree bend heh
04:29 PM perry_j1987: phone buzzed in my pocket i checked it and then hit the probe button without plugging in the probe first lol
04:29 PM Tom_L: perry_j1987, these guys will fix you right up: https://www.carbideprobes.com/
04:30 PM Tom_L: unless you screwed up the innards
04:30 PM perry_j1987: they dont have m2.5 thread
04:31 PM perry_j1987: innards are good still
04:34 PM JT-Shop: https://www.corvetteforum.com/forums/c8-general-discussion/4747979-total-c8-in-la.html
04:37 PM Tom_L: might need a front clip
04:39 PM Tom_L: saw a similar 2 piece ferrari a while back
04:39 PM Tom_L: seats were ejected along with the steering column in one direction the rest was scattered like a wood mulcher
04:41 PM Tom_L: https://nypost.com/2022/12/18/ferrari-splits-in-half-kills-one-in-california-car-crash/
04:43 PM Tom_L: there is no cure for stupid
04:43 PM JT-Shop: nope
04:43 PM XXCoder: stupid with lead foot is the worse
04:45 PM Tom_L: common thread: California
04:47 PM roguish[m]: Tom_L: stupidity is universal capital crime.......
05:32 PM JT-Shop: a bit of panic could not find the bill of sale for the C5... but finally found it and the title stub
05:46 PM Tom_L: good thing to have
05:47 PM Tom_L: our state holds the title now until it's clear
05:48 PM Tom_L: they used to send them out with a lien attached
05:49 PM JT-Shop: I think Missouri does that too, but I've not financed a car/truck since the 90's
05:50 PM Tom_L: i signed for the kids to help them get started
05:50 PM Tom_L: the trucks were nearly as much as a c8
05:50 PM Tom_L: not quite but close
05:53 PM JT-Shop: truck prices are crazy for all but Honda
05:53 PM Tom_L: of course being kids they wanted the fancy ones
05:53 PM JT-Shop: my fully loaded RTL-E came in at $45k
05:54 PM JT-Shop: I think my buddy paid $65k for his king ranch
05:55 PM Tom_L: i was surprised their honda trades were nearly what they paid for them
06:01 PM XXCoder: JT-Shop: honestly I dont know why trucks prices is nuts now
06:04 PM JT-Shop: and that's MSRP price that's nuts on the big 3 trucks
06:04 PM JT-Shop: of course you can't even get a Honda Ridgeline today... last time I was at the dealer for service they had about a dozen new cars and no trucks
06:07 PM JT-Shop: Tom_L, on my way home from the dealer today I was on an empty street and turned on the performance thingy and nailed it from a dead stop and holy shit batman that thing can move
06:08 PM JT-Shop: 3.7 seconds 0-60... the front came up about 6 inches
06:08 PM JT-Shop: I can't wait to launch it at least once
06:09 PM XXCoder: crazy
06:12 PM JT-Shop: yup it's nuts for sure but I still want to find a safe place to a launch and experience at 2.8 second 0-60 at least once
06:13 PM XXCoder: it would be to be pretty dang stright, and no inconvient cars
06:14 PM JT-Shop: actually the road I was on was perfect, extra wide, no development at all just an empty street
06:14 PM JT-Shop: and no cross streets!
06:15 PM XXCoder: ahh sounds like roads laid out to make new neighborhood but didnt pan out
06:15 PM JT-Shop: yup
06:24 PM XXCoder: lathium-ion battery inventor died at 100 years old. dang
06:27 PM JT-Shop: wow that's old... more folks are hitting the century mark no a days
06:28 PM XXCoder: life average is actually going down in usa
06:29 PM JT-Shop: I'm glad I'm not "average" lol
06:29 PM JT-Shop: anyway it's time to lock up and head inside
06:30 PM XXCoder: :)
06:38 PM Tom_L: JT-Shop, 60+ kid has a new toy now
06:40 PM Tom_L: there's a couple industrial roads here guys use for that
06:42 PM flyback: from the ventoy guy, new pxe server project https://www.iventoy.com/en/index.html
07:59 PM CAKESLOB: I have a 4096 line encoder with A/B . For some reason Z isnt working but thats for later. Is it possible that I can do lathe threading using just encoder raw count connected to something?
07:59 PM Tom_L: you need the index pulse
08:00 PM CAKESLOB: cant I just start counting or something when threading starts?
08:01 PM CAKESLOB: like threading starts, it counds 4096 and then sends the index count reset or something
08:02 PM CAKESLOB: so like fake an index by resetting the index pin every 4096 pulses?
08:02 PM Tom_L: you'd have to do something custom
08:03 PM CAKESLOB: but it sounds possible right?
08:04 PM Tom_L: technically you can do it with linear moves in the cad file and make multiple passes
08:04 PM Tom_L: just more work for you
08:04 PM Tom_L: http://linuxcnc.org/docs/stable/html/gcode/g-code.html#gcode:g76
08:05 PM Tom_L: pretty sure that one is intended for lathe
08:05 PM Tom_L: also pretty sure you need an index with it
08:06 PM Tom_L: you could also use a 3 point file but are you willing to go to that extreme?
08:08 PM Unterhausen: an index should be fairly easy to construct though
08:09 PM Tom_L: i would think so
08:10 PM Tom_L: CAKESLOB, are you sure Z isn't working? it's going to be a very short pulse
08:11 PM CAKESLOB: im almost positive
08:11 PM CAKESLOB: last time I measured, I get no change in voltage at all
08:12 PM CAKESLOB: its like 0.07
08:12 PM Tom_L: you might see it on a scope but i doubt hal show would show it
08:12 PM CAKESLOB: and its never been repeatable when it did send a signal those few times
08:12 PM CAKESLOB: like 1 in 20 rotations
08:12 PM Tom_L: i doubt you'd see a voltage change on that small a pulse
08:13 PM CAKESLOB: if i search for ity, I can find it after like 20 turns, then I try to go backwards and nothing
08:13 PM Tom_L: i doubted mine was working but i hooked it up and rigid tapping worked so...
08:14 PM CAKESLOB: i should be able to tell for sure if i hook it up to index reset
08:15 PM Tom_L: i hooked one up to a fpga to test if it was working: https://www.youtube.com/watch?v=o8lezpJhfAo
08:15 PM CAKESLOB: Unterhausen yeah it would be, but my tiny lathe is so nice and compact
08:17 PM Tom_L: might be about as easy to get another encoder
08:19 PM CAKESLOB: its easier, my lathe is tiny, ive considered my options for addinfg an index, and its not pretty
08:19 PM CAKESLOB: the whole encoder part isnt exactrly pretty
08:19 PM CAKESLOB: well, its ok, but not cnc pretty
08:20 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Encoder1.jpg
08:20 PM Tom_L: you can see how tiny mine is
08:20 PM Tom_L: omron? i think.. i have a data sheet here somewhere
08:20 PM Tom_L: 500cpr
08:21 PM CAKESLOB: i have a few omron ones small like that
08:21 PM CAKESLOB: but tommy, when I say tiny...
08:21 PM Tom_L: ball bearing
08:21 PM Tom_L: like watchmaker small?
08:22 PM CAKESLOB: smaller
08:22 PM CAKESLOB: doing a pic

08:27 PM CAKESLOB: yeah
08:28 PM Tom_L: one of those omron would fit in there somewhere :)
08:28 PM CAKESLOB: yeah, I put it beside it for comparsion
08:28 PM Tom_L: are those nema17 or 23?
08:28 PM XXCoder: interesting
08:28 PM CAKESLOB: lol
08:28 PM CAKESLOB: 11
08:28 PM Tom_L: :)
08:29 PM XXCoder: i guessed it was tiny because couplers looked huge
08:29 PM CAKESLOB: the e6a2 cs3 would fit, i need to buy one with abz though
08:29 PM CAKESLOB: such a pain thopse couplers
08:29 PM CAKESLOB: 3mm to 5mm i need to buy ones ionstead of using a spacer sleeve
08:29 PM CAKESLOB: 5mm ballscrews
08:31 PM CAKESLOB: the motor has huuuuge magnetic cogging though, I would need to thread at a high-ish speed
08:31 PM CAKESLOB: https://vi.aliexpress.com/item/1005002374763839.html?spm=a2g0o.cart.0.0.7d0238davefAhQ&mp=1&gatewayAdapt=glo2vnm
08:31 PM CAKESLOB: wtf why viet
08:32 PM CAKESLOB: anyways, this is the encoder im using now, and z has never output properly
08:32 PM CAKESLOB: a/b count perfectly though
08:33 PM XXCoder: tried swapping those see if its board or something else?
08:33 PM CAKESLOB: I didnt design the spindle to use an encoder, I didnt think i would be this fancy when I made the spindle 5 years ago
08:33 PM CAKESLOB: swapping the encoder?
08:34 PM XXCoder: yeah
08:34 PM XXCoder: see if it follows it or not
08:35 PM CAKESLOB: im buying 2 replacements as we speak. I swapped z with b, and it counts good
08:35 PM CAKESLOB: might aswell look for a chinese omron knockoff while im at it
08:36 PM XXCoder: one that was on b works well on z?
08:36 PM XXCoder: while one that was on z moved to b still doesnt work?
08:36 PM CAKESLOB: yeah, controller side i swapped b with z
08:36 PM CAKESLOB: and it counted fine
08:37 PM CAKESLOB: but not with z
08:37 PM XXCoder: so its either wires or board
08:37 PM CAKESLOB: it followed the z channel is what I mean
08:37 PM XXCoder: if can, swap wires and see if problem stays
08:38 PM CAKESLOB: like the encoder z -> b never counted
08:38 PM CAKESLOB: encoder b -> z counted
08:38 PM CAKESLOB: it followes the index from encoder
08:38 PM XXCoder: yeah though it may be still problem with wires rather than encoder
08:38 PM XXCoder: since you swapped at connector side
08:39 PM CAKESLOB: ohh, to test that I used on of my hook probes right off the chip
08:40 PM XXCoder: ahh ok. so its indeed board that has issue
08:40 PM XXCoder: wonder whats up with it
08:40 PM CAKESLOB: its one of those magnetic encoders, the data sheet didnt give a air gap distance though
08:40 PM XXCoder: (encoder board)
08:40 PM CAKESLOB: it used to count like 1 pulse every now and then, but never reopeatabvle
08:40 PM CAKESLOB: like 1 every 20, then 2, then 40,
08:41 PM XXCoder: hmm any difference on distance between magnet and board on b and z?
08:41 PM XXCoder: maybe try move magnet closer to sensor without actually touching anything see if its more reliabke
08:42 PM CAKESLOB: i ahve a .5mm airgap right now,
08:42 PM CAKESLOB: a/b counted good in all the distances test i did
08:42 PM CAKESLOB: z, nothing repeatable
08:42 PM XXCoder: honestly from tests you did, sounds like its just bad
08:43 PM XXCoder: maybe sensor is borked, or something else on it is
08:43 PM CAKESLOB: yeah, and if it wasnt, i broke it testing
08:44 PM CAKESLOB: i might order the chip from digikey and replace it
08:44 PM XXCoder: any visible damage on board?
08:44 PM CAKESLOB: only difference in the (lack of) schmatic, is z channel has what looks like an smt capaciotor
08:44 PM XXCoder: tried probing it see if anything is different
08:44 PM XXCoder: yet?
08:44 PM CAKESLOB: i just did some voltage tests
08:46 PM CAKESLOB: I also need to findout if its something about my wiring
08:46 PM CAKESLOB: my board is 5v tolerant, but the io is 3.3
08:47 PM CAKESLOB: this encoder is 5v
08:48 PM Tom_L: also it it open collector outputs?
08:48 PM Tom_L: you may need pullups on those
08:48 PM Tom_L: i had to put pullups on my omron
08:50 PM CAKESLOB: I was thinkiong something like that, but a/b work fine, but z does have some extra cap on it
08:50 PM CAKESLOB: ok last pic before I eat dinner
08:51 PM * BIG_KEVIN420[m] uploaded an image: (2499KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/TYTUCZVjjWERcuTHOEaZKCKo/20230626_2046441.jpg >
08:51 PM Tom_L: try it and see
08:51 PM CAKESLOB: I can configure pullup in my firmware configuration
08:51 PM CAKESLOB: aswell
08:52 PM XXCoder: thats definitely cool. cant wait to see ut complete
08:56 PM roycroft: my second set of bow ties is going much better
08:56 PM roycroft: i haven't finished yet, but i pocketed to exact size, not 0.005" over, and i used plenty of shaper tape
08:57 PM roycroft: the pockets seem to be spot on
08:57 PM onceloved: Very delicate, very beautiful. Can you please share the method of making it?
08:57 PM roycroft: the only issue is the rounded corners - i need to clean them up with a chisel, and then i can do the real test fits
09:04 PM XXCoder: yeah no such thing as zero diameter tool :D
09:05 PM roycroft: although an engraving tool is set as zero diameter
09:06 PM XXCoder: weird. cant set tool diameter?
09:06 PM roycroft: yes, of course
09:06 PM roycroft: but an engraving tool comes to a point
09:06 PM roycroft: so its diameter approaches zero at the point
09:07 PM XXCoder: ahh yeah. theres a cheat method to have zero radius inside corners abusing that fact also
09:07 PM roycroft: roycroft.us/BowTies/BowTies3.jpeg
09:07 PM roycroft: that's how i laid out the top
09:07 PM XXCoder: (for inlays)
09:07 PM roycroft: one can cut through shaper tape, but it gums up the cutter, so i try to avoid that
09:08 PM roycroft: roycroft.us/BowTies/BowTies4.jpeg
09:08 PM roycroft: then i draw a line around the inlays and remove them
09:08 PM roycroft: then i scan the shaper tape and it memorizes the workspace, including the pencil lines
09:08 PM roycroft: roycroft.us/BowTies/BowTies5.jpeg
09:09 PM roycroft: i cut out the pockets first
09:09 PM roycroft: note that i had some shape tape health issues with the middle bow tie, and had to add more shaper tape over on the right
09:09 PM roycroft: i can do that and rescan the workspace, and it just adds the new tape
09:09 PM roycroft: roycroft.us/BowTies/BowTies6.jpeg
09:10 PM roycroft: that's how i guide the cutter - the blue area is darker where it's uncut, and turns brighter as i cut it
09:10 PM roycroft: roycroft.us/BowTies/BowTies7.jpeg
09:11 PM roycroft: that's after the final cut, to the line (not the pencil line, but the invisible line where i placed the object)
09:11 PM roycroft: roycroft.us/BowTies/BowTies8.jpeg
09:11 PM roycroft: and a close-up of one of the recesses
09:11 PM XXCoder: interesting
09:11 PM roycroft: after dinner i'll chamfer the bow ties slightly, clean up the edges of the recesses, make the corners pointy, and then inlay the parts
09:12 PM roycroft: i had to use a lot of shaper tape for that
09:12 PM XXCoder: that things pretty cool but I doubt I would get one
09:12 PM roycroft: the stuff is about 12 cents/foot
09:12 PM roycroft: it's going to save me heaps of time
09:12 PM XXCoder: is it reclaimable?
09:12 PM roycroft: no
09:13 PM roycroft: it's one use, and i've verified that
09:13 PM roycroft: it does not come off the wood cleanly
09:13 PM roycroft: but i'm going to make some jigs and fixtures that will be permanant and reusable
09:13 PM XXCoder: I guess it would never be used for stuff that needs though cut
09:13 PM roycroft: this project is not typical of what i'll be using it for
09:14 PM roycroft: i think it's going to work out for me exactly as i expect and need it to, so i'm pretty happy so far
09:16 PM XXCoder: seems to work well
09:21 PM roycroft: it's not a stand-alone gantry cnc router, and never will be able to take the place of one
09:21 PM roycroft: but it's complementary to that and to strictly hand work
09:22 PM roycroft: it's going to have a significant place in my work flow
09:22 PM XXCoder: it can also work with huge parts that cnc router cannot
09:22 PM roycroft: yes
09:22 PM roycroft: and getting this is actually making me think about building my gantry cnc router smaller than originally planned
09:23 PM roycroft: knowing i can use the origin for larger stuff
09:25 PM Tom_L: get lots of tape :)
09:27 PM roycroft: for big projects, yes
09:27 PM roycroft: anyway, i don't plan on posting heaps of pictures of everything i do with the origin here, but i thought folks might be interested in how it works while actually making something with it
09:28 PM XXCoder: its certainly not common cnc
09:28 PM roycroft: definitely its own niche
09:28 PM roycroft: until the patents expire, of course :)
09:29 PM roycroft: speaking of which, some of the festool domino patents will expire next year
09:29 PM Tom_L: the only thing i'd ever heard of that even came remotely close was something sears sold years back
09:29 PM XXCoder: yeah. I wonder if open source designs would pop up then
09:29 PM Tom_L: and i don't even know much about that
09:29 PM roycroft: it will be interesting to see what folks do to compete with that once they're able to use some of the technology
09:30 PM roycroft: there's already a roomba router
09:30 PM roycroft: not an actually roomba, of course, but it moves like one
09:30 PM roycroft: it has six giant tires
09:31 PM roycroft: you set up some posts with reflectors/sensors/lights - i'm not sure what they do
09:31 PM XXCoder: theres another one thats basically cnc spider
09:31 PM roycroft: you set them up kind of like how transporter enhancers are set up on star trek
09:31 PM roycroft: three of them surround the workpiece, and the roomba router tracks where it is by talking to them
09:32 PM Tom_L: triangulation
09:32 PM XXCoder: lps would have been quite accurate
09:32 PM Tom_L: need to pick up some more ram for this spare mb now
09:38 PM XXCoder: https://www.youtube.com/shorts/pFxgtxyOM9g?feature=share
09:38 PM XXCoder: someone cmpleted millenium milling mill machine
09:47 PM roycroft: https://www.youtube.com/watch?v=jjzR1uRH7MQ
09:48 PM roycroft: the roomba router
09:50 PM XXCoder: interesting
09:54 PM XXCoder: sadly I cant find spider cnc project
09:54 PM XXCoder: since to companies naming some cheap ruter line spider cnc
09:55 PM roycroft: i just wonder how accurate the roomba router is
09:55 PM XXCoder: found it!
09:55 PM XXCoder: https://www.driftworks.com/forum/threads/video-incredible-6-legged-walking-cnc-robot.79143/
09:55 PM roycroft: i'd guess it can hold 0.030" or so
09:55 PM XXCoder: roy honestly it depends on lps by quite a lot
09:55 PM roycroft: which is fine for some stuff
09:56 PM XXCoder: I googled for "walking cnc machine"
09:56 PM XXCoder: which found it
09:56 PM XXCoder: https://youtu.be/quN37YskoaM
10:09 PM roycroft: i really don't know much about the accuracy and repeatability of lps
10:20 PM CAKESLOB: https://www.aliexpress.com/store/group/Corrugated-Pipe-Joint/5380144_1000000472082.html?spm=a2g0o.store_pc_allProduct.0.0.26ef5d4dSOIgU2
10:20 PM CAKESLOB: anyopne ever use this bnefore?
10:20 PM CAKESLOB: i want to use it instead of e chain for another project
10:22 PM roycroft: i've used that stuff heaps of times, but i don't think i'd trust it to hold up under constant movement
10:24 PM Tom_L: is it split?
10:24 PM Tom_L: auto use that sort of stuff on things
10:24 PM CAKESLOB: hmmm..i need like a 3 dimensional cable support
10:24 PM CAKESLOB: yeah, we have it on some scara robots at work
