02:14 AM Deejay: moin
04:23 AM Tom_L: morning
05:26 AM JT-Cave: morning
06:10 AM srk_ is now known as srk
06:38 AM srk_ is now known as srk
07:23 AM rigid: yay! remote GUI works... \o/
07:25 AM rigid: just jogged my mill on the headless raspi linuxcnc from axis on my desktop via NML over wifi :-P
07:52 AM rmu: congratulations
07:52 AM rmu: you will probably have fun when you try to load a g-code file
08:00 AM JT-Cave: hmm today's list includes pick up hoses and prepare for a freeze tonight, lay the Bluewing on it's side and change the rear tire, order the parts needed to rebuild the forks, take a nap, ship a package... maybe not in that order
08:01 AM travis_farmer: Morning :-)
08:04 AM rigid: rmu: the g-code related tests pass and I can load a g-code file into axis just fine. But starting the job does nothing and gives no error.
08:06 AM rmu: rigid: try putting the exact same file on the exact same path on the rpi
08:07 AM rigid: but if linuxcncrsh can run the g-code, axis will probably somehow aswell
08:07 AM rmu: you need the file on the rpi
08:07 AM rigid: ah, axis reads the file directly?
08:07 AM rmu: axis reads it directly
08:07 AM rigid: ...and then generates the mdi messages?
08:07 AM rmu: and the .var file is also a problem i think
08:08 AM rmu: no axis just calls taskplanopen with the filename
08:08 AM rigid: ah, yeah.
08:11 AM rmu: ceterum censeo, nml esse delendam
08:29 AM Loetmichel: hmm, has anyone a german source for a minimum 14mm dia slotting mill bit with a 6mm shaft? i have to cut 5mm deep 10mm high undercuts into an AlMg3 billet with a CNC 6040
08:30 AM Loetmichel: s/5mm/4mm
08:33 AM rigid: rmu: how would you replace it?
08:33 AM rigid: hm, copying the file doesn't really work. The last line I get is "emcTaskPlanOpen(/tmp/tmp0vsdxvq8/test.ngc) returned 0" and nothing happens
08:34 AM rmu: rigid: path is identical on both machines?
08:34 AM rigid: yep. also from the temporary copy axis creates
08:36 AM rmu: re. replacement, i'm not sure, flatbuffers + zeromq or something along that line. would fix some problems and make it easier to extend
08:36 AM rmu: and would also allow writing GUI running in browser
08:47 AM rigid: porting the linuxcnc protocol to flatbuffers is quite a lot of work.
08:49 AM rmu: i think the flatbuffers thing would be the easy part...
08:49 AM rigid: hm, running a job in tklinuxcnc says "EMC_TASK_PLAN_RUN cannot be executed in auto mode when the interpreter is reading."
09:22 AM rigid: I think nothing about this would be easy
09:33 AM rmu: no probably not
09:48 AM CaptHindsight: what is the messaging that ROS2 uses?
09:48 AM CaptHindsight: DDS, zeromq, mqtt?
10:13 AM rmu: CaptHindsight: https://fast-dds.docs.eprosima.com/en/latest/index.html
10:52 AM solarwind: CaptHindsight fixed the Z axis issue on my mill :) it was just a matter of tightening the gib
10:52 AM rene-dev5: CaptHindsight dds is not suitable for linuxcnc
11:01 AM Tom_L: Loetmichel, search for a keyseat cutter
11:02 AM Tom_L: not sure what standard metric dimensions on those are but one might work
11:04 AM Tom_L: 16.5mm x 10mm shaft... largest 6mm shaft is a 10.5mm cutter
11:04 AM -!- #linuxcnc mode set to +v by ChanServ
11:04 AM Tom_itx: https://www.grainger.com/search?searchQuery=metric+keyseat+cutter&searchBar=true
11:04 AM Tom_L: ymmv in germany
11:28 AM Tom_L: also you're likely to get too much tool deflection with a 6mm shank 14mm cutter
11:35 AM Rab: Could also try a small slitting saw with a ton of passes. But I assume the spindle is fairly small and high speed.
11:35 AM Rab: Are you set up to use coolant?
11:36 AM Tom_L: doubt you'd find a slitting saw with that small a shank
11:37 AM Tom_L: and if he has to take the slot to the floor those wouldn't work anyway
11:38 AM Tom_L: he may be up against a wall trying to cut that slot on that machine too
11:38 AM Rab: There are slitting saws for e.g. Dremel with very small arbors. Not exactly industrial equipment, but they might perform in aluminum with coolant.
11:39 AM Rab: Yeah, I don't know if the spindle would run low enough for a saw. Or even a 14mm cutter.
11:39 AM Loetmichel: Tom_L: Yeah, the shaft is my problem. The spindle on the 6040 has an ER11, so max 8mm shaft
11:39 AM Tom_L: he's probably gonna have to do some hunting to find that cutter
11:40 AM Tom_L: EDM :)
11:40 AM JT-Shop: chainsaw
11:41 AM Tom_L: you could always have one ground from carbide
11:41 AM Loetmichel: Tom_L: been there done that... (slitting saw to the bottom)... was unnerving though.
11:41 AM Tom_L: less tool deflection but $$$
11:42 AM Tom_L: butt pucker moment?
11:42 AM Rab: I have a few second-hand tools where someone cylindrical ground down e.g. a 3/4" end mill to chuck into a 3/8" collet. Perhaps you can find a shop to grind down off-the-shelf tooling.
11:43 AM Tom_L: shouldn't be too hard
11:43 AM Tom_L: get the 16mm x 10mm shank and have it ground
11:43 AM Tom_L: those are all generally hss
11:43 AM Rab: yeah
11:44 AM Tom_L: better get 2 though :)
11:44 AM rmu: Loetmichel: silver solder a piece of 14mm carbide onto 6mm shank, grind single lip cutter ;)
11:45 AM Tom_L: unbalanced at those rpm
11:45 AM Rab: Loetmichel, what are the wattage and RPM range of your spindle?
11:45 AM Tom_L: need i post that yt again??
11:45 AM Tom_L: :)
11:50 AM Rab: Use rigid tooling like a CNC shaper? A good challenge for a 6040. :D
11:52 AM JT-Shop: nap time
11:53 AM Tom_L: gettin close for sure
11:56 AM CaptHindsight: rmu: he started taking a look at DDS for LCNC https://github.com/auto-mation-assist/LinuxCnc-OpenDDS-Work
11:58 AM CaptHindsight: Rab: would be great for perfectly squared cheeses
11:59 AM rmu: CaptHindsight: seems that just contains opendds installation instructions
12:00 PM CaptHindsight: solarwind: 0x0001F44D
12:00 PM CaptHindsight: rmu: that is as far as he got publicly
12:00 PM CaptHindsight: 0xF0 0x9F 0x91 0x8D
12:02 PM rmu: is #linuxcnc now in number-station-modeß
12:02 PM rmu: ?
12:03 PM CaptHindsight: 7
12:03 PM CaptHindsight: 2 1/3cm
12:04 PM roycroft: 2.95 furlongs
12:06 PM CaptHindsight: 2 95/100 furlogs
12:06 PM CaptHindsight: hairballs that make it all the way through
12:07 PM Loetmichel: Tom_L: http://www.cyrom.org/palbum/main.php?g2_itemId=5471&g2_imageViewsIndex=1
12:07 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=5474&g2_imageViewsIndex=1
12:07 PM roycroft: II + XC/C stadia
12:09 PM Loetmichel: Rab: 800W chinese "HF" spindle, 24krpm @400Hz watercooled. No idea what torque. 35mm diameter facing in Pertinax(r) works at 8kRpm, but not deeper than about 0.3mm or the spindle VFD goes in "overload"
12:09 PM rmu: DDS is a behemoth. seems to even include ACE and TAO. brrr
12:11 PM CaptHindsight: mebe mqtt fitz
12:11 PM Loetmichel: Tom_L: yes, that would be my last attempt (getting a 16mm by 6mm and have the 10mm shaft ground down to 8mm)
12:13 PM Loetmichel: Rab: are you serious? using a 6040 as a shaper may work in styrofoam or in young gouda, certainly not in alu with anything close to "precision"
12:16 PM Rab: Loetmichel, I'm not serious.
12:16 PM rmu: Loetmichel: put billet into car, go to shop with real mill
12:18 PM Loetmichel: Yeah, the "series" for the new Notebook case will be made in a real shop. Sadly i have to have a prototype in 2 weeks flat, ready to run in the measurement chamber and the co-worker that does the construction of the full alu enclosure isnt even done with the design yet, so i will have to make the prototype on said 6040
12:19 PM CaptHindsight: I thought about milling laptop enclosures 10-20 years ago
12:19 PM Loetmichel: (which will be "fun" in itself, to mill a Notebook case out of a couple 500*400*20mm^3 slabs of alu
12:19 PM Loetmichel: :)
12:19 PM CaptHindsight: are the Toughbooks and similar still formed from sheet?
12:20 PM Loetmichel: toughbooks are usually cast Al/Mg alloy with lots of plastics.
12:20 PM CaptHindsight: but now I can print them with photopolymers in minutes
12:20 PM Loetmichel: we do Shielded, not rugged ;)
12:20 PM Loetmichel: so plastics is a no-go, faraday cage and so on.
12:21 PM CaptHindsight: oh I can fill urethanes with copper
12:21 PM CaptHindsight: shields nearly like bulk copper
12:21 PM rmu: CaptHindsight: i don't know if that discussion (nml replacement) is serious; I would prefer something that doesn't need a broker, can talk directly talk to browsers, and does not involve giga-LOCs of code
12:21 PM CaptHindsight: rmu: which messaging system?
12:22 PM rmu: perhaps zeromq
12:22 PM CaptHindsight: is that what machinekit used?
12:22 PM rmu: yes i think so
12:22 PM rmu: protobuf + zeromq
12:22 PM rmu: i would probably go for flatbuffers
12:23 PM Loetmichel: CaptHindsight: that would be great if you can get below ~1 ohm per cm. Usually its a lot higher though. We thought about getting it 3d metal printed but as i said: time constraints.
12:24 PM CaptHindsight: Loetmichel: I can easily get that low.
12:24 PM CaptHindsight: I build and formulate all my stuff
12:24 PM CaptHindsight: so I make it work vs almost work
12:25 PM Loetmichel: Well, in the end its for some elderly bigwigs in the military. they will have to live with the ~5.5kg brick that once was a 17" HP notebook, not me. :)
12:26 PM Loetmichel: If i cant find said slotting saw/slotting mill bit it will be closer to 6kg... So not the biggest problem :)
01:44 PM Tom_L: Loetmichel, is that a regular sawblade?
01:44 PM Loetmichel: Tom_L: yes
01:44 PM Tom_L: what hole size?
01:45 PM Loetmichel: and an M10 bolt
01:45 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/Slitting_saw1.jpg
01:45 PM Loetmichel: IIRC it was an 80mm sawblade with a 10mm hole
01:45 PM Tom_L: the small holder is a sherline
01:45 PM Tom_L: iirc the small holes are 5/8"
01:46 PM Tom_L: but there's a bolt on the bottom
01:46 PM Loetmichel: i just turned the head of an M10 bolt down until it was smaller than the difference between Teeth widthand blade steel width
01:47 PM Loetmichel: in effect i made a sawblade into a "slitting saw" with Z clearance.
01:47 PM Tom_L: that might work on a carbide blade but not hss
01:47 PM Tom_L: unless you offset the teeth
01:48 PM Loetmichel: but the thought that that thing was rotating at 24kRPM while sitting on a barely 0,2mm wide shoulder was a bit uncomfortable ;)
01:48 PM Tom_L: well, i'm just glad i was here and not there :)
01:48 PM Loetmichel: Usually the HSS saw teeth are also offset (if meant for wood)
01:49 PM Tom_L: the ones i have are for metal with no offset
01:49 PM Loetmichel: but if its a real slitting saw blade its of course (usually) not offset
01:51 PM Tom_L: https://www.youtube.com/watch?v=Ls1XabACpKI
01:51 PM Tom_L: a 1" one i got for that project
01:51 PM Tom_L: took every bit of the cutter clearance
01:52 PM JT-Shop: trigger
01:53 PM Loetmichel: Tom_L: yeah, that would do. As i said: i'll have to do some "undercuts" on the inside of a Notebook enclosure.
01:53 PM Tom_L: the one i got had an undercut neck
01:54 PM Tom_L: iirc the shank was either 3/8 or 1/2"
01:54 PM Loetmichel: But as i mentioned: on a CNC 6040, so it'll probably sound a bit different at 80krpm but VERY light cuts (dont dare to do more than 0.1mm or that springy little thing will bite in and ruin the enclosure)
01:54 PM Tom_L: 2k rpm @ 5 ipm iirc
01:56 PM Loetmichel: eh
01:56 PM Loetmichel: i meant 8kRPM
01:56 PM Loetmichel: that 80k is probably a bit much ;)
01:57 PM Tom_L: i got a spindle with more low end torque than most of those chinaco ones
01:58 PM JT-Shop: package shipped, nap done, hoses put up time for a break
01:58 PM Loetmichel: point was that a CNC 6040 is a router/engraver. Its gantry is basically 2 25mm round steel bars with linear ball bearings on it. Not really "rigid" if you know what i mean
01:58 PM Loetmichel: hanging free over close to 500mm
01:58 PM Rab: FWIW there are apparently 7mm and 8mm ER11 collets.
01:59 PM Loetmichel: Rab: i have 8mm ER11
01:59 PM Rab: ahh
01:59 PM Loetmichel: still no chance for a 10mm
01:59 PM Loetmichel: :)
01:59 PM Rab: Indeed.
01:59 PM Rab: So the 6mm shaft requirement is for the correct overhang at 14mm OD?
02:00 PM Loetmichel: yep
02:00 PM Tom_L: barely
02:00 PM Loetmichel: 8mm shaft and 18mm diameter works just as well
02:00 PM Rab: ah
02:00 PM Loetmichel: ideally i have to go 5mm "deep" into the sides
02:01 PM Loetmichel: 4mm will do though
02:03 PM Loetmichel: Its kinda like what my development boss warns me often about.. "If you do that we have to sell it with "welder included" because they cant get out after welding that shut!"
02:07 PM CaptHindsight: heh, I once had an enclosure delivered the day before a trade show in China and the only way to assemble the enclosure completely was to leave someone inside to tighten the fasteners
02:08 PM CaptHindsight: 4 days was just too long to leave someone in there
02:08 PM justache is now known as justHaunted
02:12 PM -!- #linuxcnc mode set to +v by ChanServ
02:12 PM Tom_L: Loetmichel, how deep into the material is the start of the slot?
02:13 PM Tom_itx: https://www.grainger.com/product/KEO-Standard-Keyseat-Cutter-High-33UW09
02:13 PM Tom_itx: you'd still have to trim down the shank
02:14 PM Rab: Loetmichel, Misumi have several types of t-slot cutters which would work. Many of them have a large shank, but a 6mm neck around 20mm long. The shank could be cut off, leaving enough neck to chuck up in ER11. https://us.misumi-ec.com/vona2/fs_machining/T0105000000/T0105080000/
02:14 PM Rab: Diameters up to 15mm and possibly larger.
02:15 PM Loetmichel: Tom_itx: the notebook body will be made out of two 500*400*20mm slabs of alMg3.
02:16 PM Loetmichel: the slots are basically 10mm "deep" on the sides so that 5mm of "screw thread place" are left over to combine the two halves.
02:16 PM Rab: I can't figure out how to link to specific products on their site, but browsing around turns up likely candidates by Fukuda and Taiyo Tool; possibly others. Feasibility of ordering from DE is another matter.
02:17 PM Loetmichel: Tom_itx: i found several of those with 10mm at hoffmann tools. Those are my "fallback" if i cant find one with 6 or 8mm shaft, will have to grind that shaft down in the lathe (Brrr, the ways will NOT thank me for that!)
02:18 PM Rab: Blade width is another question. I would guess with an 800W spindle, it needs to stay pretty narrow. See P/N TC-LS15-2 for 6mm neck, 15mm OD, 2mm blade width.
02:19 PM Tom_L: i'd get a narrow one and make 2 passes for that reason
02:20 PM Loetmichel: Rab: thanks, looking into it. As i said: the 800W will probably NOT be the problem as i am pretty sure that the gantry will flex before the spindle torque is depleted
02:20 PM Rab: Loetmichel, yes, that's possible.
02:20 PM Loetmichel: more like 20 passes, i doubt i can cut more than 0.1mm deep at a time
02:21 PM Loetmichel: @ Tom_L
02:21 PM Tom_L: s/passes/steps
02:23 PM Loetmichel: yeah, i meant more like 50 passes times two steps :)
02:25 PM Loetmichel: that thing will be on the looooong side anyways, turning two 500mm by 400mm by 20mm slabs and one 500 by 400mm by 10mm slab into a 5.5kg notebook will take quiiiite a while to mill out with a 6mm two flute on a 6040 :)
03:08 PM rigid: hehe, there's a fancy drawing bug in axis when running gcode remotely: https://coderdu.de/share/1698696284334216623.jpg :)
03:10 PM rigid: to boldly run codepaths no man has run before...
03:10 PM Tom_L: not picking up the offsets
03:11 PM Tom_L: going to machine home each time
03:11 PM rigid: Tom_L: oh you see the cause? what offsets?
03:11 PM Tom_L: are you using G54..59?
03:11 PM rigid: yep
03:11 PM rigid: G54
03:11 PM Tom_L: that pic shows the bounding box of your machine cube
03:11 PM Tom_L: it's homed in the left front corner
03:12 PM Tom_L: am i right?
03:12 PM XXCoder: lasers all attack one spot
03:12 PM rigid: yes
03:12 PM Tom_L: so it's not picking up the G54 offsets
03:12 PM rigid: XXCoder: 3D invaders gone wrong
03:13 PM rigid: Tom_L: that corner is the G54 home
03:13 PM Tom_L: what is the part?
03:14 PM rigid: or do you mean each of the actual command coordinates with offsets? like "G1 ..."
03:15 PM rigid: Tom_L: part == G54 offset. it's just an empty test run
03:15 PM roycroft: i forgot how touchy my petg filament is about temperatures
03:15 PM roycroft: i printed a prototype of my heat sink mounts yesterday and it came out very nicely
03:15 PM Tom_L: rigid, that's what it looks like to me.. not seeing the G54 but using machine home
03:15 PM roycroft: i then cloned it in the slicer so i could print 4 at a time
03:15 PM rmu: rigid: those offsets are in the .var file and not available via nml
03:16 PM roycroft: i made no changes to the slicer settings
03:16 PM Tom_L: so by default it will use machine home would be my guess
03:16 PM Tom_L: since the var file isn't present
03:16 PM roycroft: and when i printed the 4-up file i got a bunch of blobs and spaghetti strings
03:16 PM rigid: omg
03:17 PM Tom_L: more fun for you :)
03:17 PM roycroft: instead of messing with it i went back to printing one at a time - i only need eight
03:17 PM rigid: Tom_L: I don't get it, why is one missing offset causing to home after each command instead of just connecting the previous vertex to the next one
03:17 PM Tom_L: as a test, copy the var file to the remote
03:17 PM Tom_L: then re run it
03:18 PM rmu: i'm not sure that picture is caused by wrong offsets
03:18 PM Tom_L: maybe
03:18 PM Tom_L: jepler would know
03:18 PM Tom_L: iirc he wrote it
03:18 PM Tom_L: axis that is iirc
03:19 PM rmu: rigid: is the DRO correct?
03:21 PM rigid: rmu: dunno, how would I check?
03:22 PM Tom_L: start at x0,y0 and do a G1 x1 or G1 y1 and see
03:22 PM rigid: Tom_L: not sure where to copy the file. it's in the tempdir axis creates but linuxcncvr loads it from the original path
03:22 PM Tom_L: mmm
03:22 PM rigid: or it doesn't load it all... at least I don't get any error that it's not found
03:28 PM rmu: rigid: the var file is specified in the ini file
03:28 PM rmu: DRO: the preview should work the same with MDI commands
03:28 PM rmu: so switch to MDI and move around
03:28 PM rigid: oh that var file, yeah that was always the same on both hosts
03:32 PM rigid: almost similar output when I clear toolpath and run "G1 Z0" https://coderdu.de/share/1698697682778659789.jpg
03:33 PM rigid: rmu: is the var file written by axis?
03:33 PM rigid: ...or modified?
03:34 PM Tom_L: it could be modified by axis
03:34 PM Tom_L: when you set your offsets
03:34 PM rmu: rigid: no, the interpreter write the var file
03:35 PM rmu: strange pic
03:35 PM rmu: i think axis doesn't look / modify the parameters
03:35 PM rigid: indeed they differ now
03:35 PM rmu: there is no screen where you see all offsets of all WCS in axis
03:36 PM Tom_L: rmu, so does axis pass the data to the interpreter when you set your G54--59 offsets?
03:36 PM rmu: Tom_L: IIRC it uses G10 to set offsets
03:36 PM rigid: rmu: you mean "View -> Show offsets" ?
03:36 PM Tom_L: that makes sense
03:59 PM JT-Shop: https://cdn.partzilla.com/MTE/pi/8/MTA3NDU4Mzg-8165860c.jpg
04:00 PM JT-Shop: I need to make that part from steel as it's out of stock for >200 days
04:00 PM JT-Shop: the finish on the inside must be smooth, any suggestions?
04:01 PM JT-Shop: smooth so it does not scratch the forks while I hammer the seal in with the tool
04:07 PM Tom_L: round nose boring bar
04:07 PM rmu: JT-Shop: round stock, boring bar, mill off half, cut
04:07 PM Tom_L: brass wouldn't work?
04:08 PM Tom_L: or maybe nylon even
04:08 PM JT-Shop: brass or bronze would work... I'll have to see if I have any stock
04:08 PM JT-Shop: has to be heavy to drive the seal and bushing in
04:08 PM Tom_L: brass would be easier on the forks
04:08 PM Rab: JT-Shop, ID/OD?
04:08 PM Tom_L: k
04:08 PM Tom_L: i got a chunk if you don't :)
04:09 PM JT-Shop: id is a bit over 45mm, od I have to measure the opening when the tube is out
04:09 PM rmu: rigid: what did you modify in axis?
04:10 PM JT-Shop: od on the small driver end
04:10 PM Tom_L: or even aluminum but that wouldn't be top choice
04:11 PM JT-Shop: aluminum would be too light I think
04:11 PM Tom_L: so that is used to 'hammer' ?
04:11 PM Tom_L: not another tool on that piece
04:12 PM Tom_L: yeah i think i get it... brass or steel would be the best
04:13 PM JT-Shop: I have a bit of 2" brass but that's too small
04:14 PM rmu: maybe cast it from lead?
04:14 PM Tom_L: i'd pin 2 halves before you start machining so the fit is good
04:15 PM Tom_L: i still have some leftover lead cutoffs from wing balast too
04:16 PM JT-Shop: I have a chunk of 1.75" id 2.75 od that will work
04:17 PM JT-Shop: it does not have to be split for a wing
04:17 PM JT-Shop: the split is for inverted forks what ever that is
04:17 PM Tom_L: do you need the split on yours?
04:17 PM JT-Shop: no
04:17 PM Tom_L: you're golden then.. fire up the lathe
04:17 PM JT-Shop: yup
04:18 PM Tom_L: i wanna see a purty knurl too :)
04:18 PM Tom_L: not..
04:18 PM JT-Shop: I think I have a knurl tool maybe
04:18 PM Tom_L: i don't but i've done many on the old automatics
04:23 PM Tom_L: another ghetto suggestion: pipe fitting with duct tape inside to pad the fork
04:25 PM LUNADA_DESKTOP: i made a rough seal driver out of aluminum tube and just saw cut it in half on the bandsaw. worked fine, no issues
04:26 PM LUNADA_DESKTOP: i literally taped it together around the fork tube lol
04:26 PM JT-Shop: if it's long enough to wack it with a hammer that would work
04:27 PM LUNADA_DESKTOP: it was like a 3" od piece of aluminum so i didnt even need a hammer
04:27 PM LUNADA_DESKTOP: the mass of it was enough to drive the seal in
04:27 PM JT-Shop: what size fork tubes?
04:27 PM LUNADA_DESKTOP: used it on a few bikes but i made it for my tl1000r
04:29 PM LUNADA_DESKTOP: looks like 50mm
04:29 PM LUNADA_DESKTOP: i made it probably 20 years ago
04:29 PM LUNADA_DESKTOP: inverted forks as well
04:30 PM LUNADA_DESKTOP: i think i even used it on my harley ableson
04:31 PM LUNADA_DESKTOP: hardly ableson*
04:34 PM rigid: Tom_L: hm, if it's missing offsets causing that drawing bug, why does it switch to home anyway? it shouldn't jump to any home, correctly offset or not.

04:45 PM rmu: rigid: does the dro jump too?
04:53 PM JT-Shop: be a nice kit if you worked on motorcycles a lot
04:54 PM JT-Shop: too bad it has 27% 1 ratings for being junk
05:00 PM rigid: rmu: everything seems to jump occasionally. also sliders for max. velocity or "active g-codes" text display
05:01 PM rigid: like a race condition where axis re-initializes before processing a new status update
05:02 PM rigid: not sure
05:04 PM rigid: yeah, the values also change in the "LinuxCNC-Status" window
05:05 PM rigid: and max_acceleration is shown as "999999999999999967336168804116691273849533185806555472917961779471295845921727862608739868455469056.0000" which seems wrong
05:14 PM LUNADA_DESKTOP: ok the machine is officially wired except for 5v to the 7i92t
05:15 PM LUNADA_DESKTOP: this pc just has a 12v power supply so i was thinking of getting 5v from the usb ports
05:38 PM rmu: rigid: just a guess, maybe the networked linuxcnc doesn't answer fast enough and status poll runs into a timeout that isn't propagated properly as error
05:42 PM LUNADA_DESKTOP: now i have no excuses for not working on the config files. i'll have to see if i can knock the rust off.
05:44 PM LUNADA_DESKTOP: JT-Shop i assume the 7i83 addition to the mesa config tool is a down the road kind of thing?
05:44 PM JT-Shop: I've been thinking about that, it's most likely to show up as a daughter card with no I/O
05:45 PM JT-Shop: the only difference is the 7i83 has an enable for each analog output
05:46 PM LUNADA_DESKTOP: not sure i need the enable pins, i think they are wired to the 7i71]
05:46 PM JT-Shop: the enables are for the analog outputs
05:46 PM LUNADA_DESKTOP: ahh
05:48 PM LUNADA_DESKTOP: net x-enable => pid.x.enable
05:48 PM LUNADA_DESKTOP: like such?
05:48 PM JT-Shop: similar
05:48 PM LUNADA_DESKTOP: got it
05:49 PM JT-Shop: I don't have the pin file up here but something like 7i83.0.analogena
05:50 PM LUNADA_DESKTOP: i found some config files in the forum using those cards, i'm going to read through those and my 7i77 file and see if i can make sense of it all
05:50 PM JT-Shop: the only difference to a 7i77 is the enables
05:51 PM LUNADA_DESKTOP: that should be easy enough, thanks
05:54 PM LUNADA_DESKTOP: have you guys ever looked into using discord for the chat?
05:54 PM JT-Shop: there used to be a bridge to something but they shut it down
05:54 PM LUNADA_DESKTOP: ah
05:55 PM JT-Shop: most are fine with using the IRC
05:57 PM LUNADA_DESKTOP: we use discord for our ABS brake hacking group (race car stuff). similar feel, just a bit easier for file and image sharing and whatnot. i know you guys have been on irc forever though
05:57 PM JT-Shop: I do miss being able to post images here
06:02 PM * JT-Shop calls it a night
06:04 PM XXCoder: bridge is still down LUNADA_DESKTOP
06:31 PM -!- #linuxcnc mode set to +v by ChanServ
06:39 PM solarwind: Hmmm, why do my hand die grinder carbide burrs never burn up or break?
06:39 PM solarwind: They spin at 20,000 RPM under very unstable cutting conditions
06:40 PM solarwind: I'm almost tempted to use them like an end mill
06:40 PM solarwind: I'm pretty sure they're also uncoated
06:42 PM Tom_L: the ones i have are uncoated but i do have a dull one
06:50 PM Tom_L: in open air where the chips can fly they may be ok but cutting a groove or pocket etc they would likely fail
08:36 PM CloudEvil: 'never burn up or break'
08:36 PM CloudEvil: - they can get very very blunt
08:36 PM CloudEvil: In some cases
08:36 PM CloudEvil: They may never 'stop cutting' fully.
09:04 PM roycroft: blunt instruments can be very capable of moving things about
09:05 PM roycroft: just less predictably than when using sharp instruments
10:00 PM turboss is now known as Relay
