12:04 AM Deejay: moin
01:17 AM mrec: Lcvette[m]: I want to hold some u-channel folded sheet metal in place on an aluminum plate. It should be held in place with a small fixed stick
01:18 AM mrec: the rounder the better so far I used a drill it didn't always go well next try would be a step drill
01:18 AM mrec: I did not test a spot drill yet
02:26 AM rmu: pcw-home: I noticed a problem in mesaflash --readhmid output from a 7i97, like here, it says "TB1-17,18,TB2 1,2 12 IOPort MuxedQCount 1 MuxQ-A (In)
02:26 AM rmu: but should probably say "TB1-17,18,TB2-1,2 ..."
02:27 AM rmu: (notice missing minus-sign)
02:27 AM rmu: that bugs pncconf discovery
04:10 AM travis_farmer[m]: G'Morning ☕️
04:53 AM Tom_L: morning
05:03 AM -!- #linuxcnc mode set to +v by ChanServ
05:15 AM travis_farmer[m]: how long before your replacement Starlink arrives?
07:10 AM SAQUZ1: good morning.. seems that I got the index+homeswitch homing working that i asked about last night:)  Just put one line net z-index-enable and all of the hal pins we were trying to tie also to another signal motor.02.index-enable, which is now commented out. But it seems that i gained a new issue. If the servo are not in the index position or
07:10 AM SAQUZ1: 90/180/270 degrees of that (+-1mm, 8mm pitch screw) the servo will jump +10 rounds and joint error of course occurs. homing will work as it should if the servo is on index already when powering or positioned on some of the poles
07:13 AM mrec: Lcvette[m]: as good as possible with a cnc, I'm also looking at stamping actually.
07:13 AM mrec: the sheet metal is fixed firm, for now I tried to use drills but that's not a good option
07:16 AM Bushman: hi
07:17 AM Bushman: so it turns out the pendant wasn't my only problem ^_^'
07:18 AM Bushman: even the sim doesn't work
07:19 AM Bushman: so i don't know what went wrong
07:19 AM Bushman: it works at home, but not here. which is werid cause it's the same version of OS and everything
07:25 AM JT[m]: Just lost power
07:37 AM JT[m]: Starlink says preparing shipment
07:43 AM mrec: Lcvette[m]: https://i.snipboard.io/RD9aPl.jpg I'm making the copper / brass parts, and there's a 6mm hole for a small stub which will hold it in place (at the backpart of it)
07:50 AM Bushman: can someone take a look at this output?
07:50 AM Bushman: https://paste.debian.net/1272309/
07:52 AM Bushman: i don't know what's wrong, but the same compilation on my home computer runs simulator just fine, but on this computer it doesn't want to run neither in SIM nor normal mode
07:53 AM rmu: Bushman: https://forum.linuxcnc.org/24-hal-components/48272-what-causes-usrmot-error-command-timeout-emcmotioninit-emctrajinit-failed
07:54 AM Bushman: hmm...
07:54 AM Bushman: latency test works fine here. let me read the rest...
07:54 AM rmu: no idea what is causing that
07:55 AM Bushman: then there's two of us now :)
08:07 AM Bushman: why am i :)
08:07 AM Bushman: it should be :(
08:07 AM Bushman: ;/
08:07 AM Bushman: i'm stuck.
08:08 AM Bushman: google leads to obvious things that i've already checked, like not runing RT kernel, or some other silly stuff
08:59 AM robinsz: Afternoon ...
09:36 AM pcw-home: rmu, was that the only 7i97 pinout typo?
09:54 AM pcw-home: anyway, in addition to the 7I97 error, I found a couple other missing hyphens in 7I95 pinout also and pushed a fix
10:04 AM perry_j1987: morning
10:06 AM perry_j1987: whew busy weekend
10:13 AM rmu: pcw-home: as far as discovery in pncconf complaining yes
10:14 AM roycroft: https://roycroft.us/15.75x9.125-Lamp-Frame-Exploded.jpeg
10:14 AM roycroft: some folks were asking for an exploded view of the lamp design i posted yesterday
10:15 AM roycroft: you can see the joinery reasonably well there
10:29 AM * JT3196[m] uploaded an image: (947KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/tTjnPPyqSJxfjJqpQOwOmHCs/image.png >
10:29 AM JT3196[m]: I want to make a vbed knitting machine at some point, but they look so complicated lol
10:54 AM Tom_L: JT3196[m], what sort of language do those use for programming?
10:54 AM Tom_L: i bet that would be complicated
10:54 AM Tom_L: JT[m], storms?
10:56 AM JT3196[m]: Python mostly at current.
11:10 AM perry_j1987: what is spindle_zero_height in probe basic
12:15 PM unterhaus: there is a nearby chicken coop fire
12:15 PM unterhaus: chickens playing with matches again, I suppose
01:17 PM unterhaus: All chickens reported safe
01:30 PM JT[m]: Small coop?
01:46 PM mystamo[m]: Hey folks. Sorry to bother. But is the install of probe basic currently broken ? I’ve been following the instructions and loaded up a Dabian 10 but getting stuck at an error for probe basic install.
01:50 PM mystamo[m]: Why do I feel like turboss just commited a fix for this.
01:50 PM TurBoss: hello
01:51 PM TurBoss8676[m]: whats the error you get mystamo
01:52 PM TurBoss8676[m]: could be
01:53 PM mystamo[m]: It’s actually been posted on the forums. Something about conversational. Sorry on my phone not on my pc for a cut and paste. But it is actually addressed on the forum. With a response that a solution is expected just in the next day or so.
01:53 PM TurBoss8676[m]: oh ok
01:53 PM TurBoss8676[m]: you may need to clone https://github.com/kcjengr/qtpyvcp_conversational_gcode then run `pip install -e ,`
01:53 PM mystamo[m]: Understanding is it’s all down to the python 2/3 debacal
01:54 PM TurBoss8676[m]: python2 or 3?
01:54 PM TurBoss8676[m]: 2.8 or 2.9 ?
01:54 PM TurBoss8676[m]: * linuxcnc 2.8 or
01:55 PM TurBoss8676[m]: we are currently polishing some debian 12 debs
01:55 PM mystamo[m]: I followed the directions from Linux CNC and installed the dabian distro with rt kernel and lcnc 2.8 latest for 7i96s boards.
01:55 PM TurBoss8676[m]: ok
01:56 PM mystamo[m]: So dabian 10
01:56 PM TurBoss8676[m]: then conversational gcode needs the master branch
01:56 PM TurBoss8676[m]: git checkout master
01:56 PM TurBoss8676[m]: default main branch is python3
01:56 PM TurBoss8676[m]: sorry for the confusion
01:59 PM mystamo[m]: Funny how I’m a scrum leader and use git in my organization and im pure struggle bussing
02:05 PM TurBoss: docs need improvement.. 😄
02:23 PM travis_farmer[m]: is it possible to have more than one encoder for jogging control? i mean, if i use one encoder on my control panel, and switch to my pendant, will the axis jump due to the differing encoder count values? or would it be best if i use the pendant for jogging, and use the control panel encoders for other stuff, like maybe feed override, or whatnot?
02:33 PM ZincBoy[CAON][m]: It is 100% possible to do that. Just needs hooking things up correctly in HAL.
02:34 PM ZincBoy[CAON][m]: I have separate knobs for feed, rapid, spindle, and jog speed overrides.
02:37 PM travis_farmer[m]: how would i connect two encoders to one axis? seems like i would need to write a comp to process the two encoders, so there is only one signal feeding the axis being jogged.
02:39 PM ZincBoy[CAON][m]: You would need a component to handle that. Essentially, you would add the two encoder outputs together. That way you could increase or decrease either one without issues.
02:40 PM travis_farmer[m]: ok, i get it now, SUM the counts, and feed the summed value to the jog
02:40 PM ZincBoy[CAON][m]: Yup.
02:40 PM travis_farmer[m]: got it, thanks :-)
02:51 PM Tom_L: and deal with the scale of each
02:52 PM travis_farmer[m]: yes, i thought of that too :-)
02:53 PM Tom_L: let me come visit when you do, i'll run the pendant and you can run the pannel
02:54 PM Tom_L: we'll see who wins
02:54 PM travis_farmer[m]: yeah, that should be interesting...
02:54 PM travis_farmer[m]: maybe i will use an XOR for the enable...
02:55 PM Tom_L: especially if they're switched between the axis too
02:55 PM Tom_L: i use a pendant for it all
02:55 PM Tom_L: i can get closer to the work and see what i'm doing
02:56 PM ZincBoy[CAON][m]: I would combine the encoders at the first stage. Before any scaling or selection. Otherwise you are asking for all sorts of interesting glitches.
02:56 PM Tom_L: yes
02:56 PM roguish[m]1: travis_farmer: you can use velocity mode in the jog mpg's
02:56 PM Tom_L: ^^ i was somewhat trying to talk him out of the idea
02:56 PM Centurion_Dan1 is now known as Centurion_Dan
02:57 PM travis_farmer[m]: ...i see...
03:00 PM travis_farmer[m]: yeah, maybe i will just use the control panel for independent stuff, like mode switching, and other things the pendant doesn't control. should make it smaller that way too
03:01 PM perry_j1987: probe tripping during cut
03:01 PM perry_j1987: what am i missing
03:12 PM Tom_L: vibration, emf noise...
03:12 PM ZincBoy[CAON][m]: You need to gate your probe input with an enable if it is noisy
03:12 PM perry_j1987: its one of those tool height setters
03:12 PM perry_j1987: it should only be looking for that probe during a probe cycle shouldnt it?
03:12 PM Tom_L: aparently not
03:12 PM ZincBoy[CAON][m]: No. I fixed it so that the probe input is looked at even during non-probe moves.
03:13 PM travis_farmer[m]: sorry for the delay, roguish , it looks like my pendant can run velocity mode, but i will have to check if my control panel, through the 7i73, can run velocity. will check tomorrow on my machine, as the docs don't say
03:13 PM roguish[m]1: here's one I have found very useful.: axis.L.jog-accel-fraction
03:14 PM roguish[m]1: travis_farmer: just thinking that if you jog in vel mode, it shouldn't matter how many encoders you have as long as you only use one at a time....
03:15 PM travis_farmer[m]: and if Tom_L ever comes to visit, we can duel with jogging dials ;-)
03:16 PM roguish[m]1: it's all here: http://linuxcnc.org/docs/devel/html/man/man9/axis.9.html
03:16 PM Tom_L: select one for x and one for y and you can have an etch-o-sketch
03:17 PM travis_farmer[m]: LMAO Tom_L
03:17 PM roguish[m]1: I figured out my jogging a long time ago, with the help of a couple of the old timers.
03:18 PM Tom_L: yeah i experimented with it when i wired mine up
03:18 PM roguish[m]1: I have 2 multiposition rotary switches, and an mpg. 1 switch selects the axis, the other selects the increment. the mpg is the encoder.....
03:19 PM roguish[m]1: use the mux comps
03:19 PM Tom_L: Alpha: SR2612F-0112-21R0B-D8-N
03:19 PM Tom_L: Mouser: 105-SR2612F-12-21RN
03:20 PM Tom_L: i use one for axis and one for rate
03:21 PM Tom_L: .1, .01, .001
03:21 PM Tom_L: i think
03:22 PM roguish[m]1: https://www.amazon.com/100PPR-Terminal-Electronic-Manual-Encoder/dp/B07G9FVHM8/ref=sr_1_1?keywords=hand+wheel+pulse+encoder&qid=1677532828&sprefix=hand+wheel+pulse%2Caps%2C148&sr=8-1
03:22 PM roguish[m]1: I have those on both mills. no problems at all.
03:22 PM Tom_L: same but mine are alum color
03:22 PM roguish[m]1: not those exact, but all the same...
03:22 PM Tom_L: yup
03:23 PM roguish[m]1: yeah, mine too
03:23 PM travis_farmer[m]: i have 3 that are similar to those
03:23 PM roguish[m]1: you can have a fracking brawl
03:23 PM travis_farmer[m]: :-)
03:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/pendant/pendant2.jpg
03:24 PM Tom_L: i was off a decimal
03:25 PM travis_farmer[m]: my pendant is a XHC LHB04
03:27 PM travis_farmer[m]: well, XHC LHB04B, to be precise
03:29 PM roguish[m]1: COOL. just got my timing pulleys for my 3:1 reduction...
03:29 PM * ZincBoy[CAON][m] uploaded an image: (1609KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/VaoqTZOqGcCHRVFCiuztKuER/image.png >
03:29 PM ZincBoy[CAON][m]: I use the XHC LHB04 pendant as well. I only have the jog axis and jog increment hooked up though. Everything else is done on the control panel:
03:31 PM travis_farmer[m]: where did you get the panel mount keyboard???
03:31 PM ZincBoy[CAON][m]: Aliexpress.
03:33 PM ZincBoy[CAON][m]: https://www.aliexpress.com/item/4000922925880.html
03:33 PM ZincBoy[CAON][m]: LOL. The picture I sent them shows up in their ad.
03:34 PM travis_farmer[m]: Hmm, a bit more $$ than i have...
03:35 PM ZincBoy[CAON][m]: It is really cheap for an industrial keyboard but it is still an industrial keyboard.
03:35 PM * roguish[m]1 posted a file: (4KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/rIYeHOZlMuQJRtoqvmzFPDOz/7i80_simple_penant_jog.hal >
03:35 PM roguish[m]1: travis_farmer: look this over.
03:35 PM roguish[m]1: ZincBoy[CA, ON]: very nice.
03:36 PM ZincBoy[CAON][m]: I destroyed 5 or 6 keyboards on my old mill with swarf/coolant and decided to splurge on this machine.
03:36 PM roycroft: i have a keyboard very similar to that, except it has a ginormous trackball on the right side
03:36 PM roycroft: i got it on ebay years ago for about $40
03:36 PM roycroft: it's earmarked for use on my milling machine, whenever i get that project done
03:36 PM roycroft: i thought i had a picture of it online somewhere, but i can't find it at the moment
03:37 PM roguish[m]1: roycroft: do you use pocket screws to put cabinets together? with glue too
03:37 PM roycroft: sometimes
03:38 PM roycroft: i'm not a big fan of pocket screws
03:38 PM roycroft: they're pretty strong, but filling the pockets is tedious
03:38 PM roycroft: and i hate the look of them
03:38 PM roguish[m]1: i'm designing my kitchen cabinets. dados in plywood. thinking of a few pocket screws to hold while the glue sets
03:39 PM roycroft: i used to use dowels and biscuits a lot for that kind of work, but now i have that fancy domino machine
03:39 PM travis_farmer[m]: i use pocket screws for joining the cabinet face frames together, and do it on the backs so they are hidden
03:39 PM roycroft: and i have to get my money's worth out of it, so almost everything i do looks like a domino solution
03:39 PM roycroft: yeah, i would never use pocket screws where the pockets are visible
03:40 PM roguish[m]1: aggreed
03:40 PM roycroft: but i'm one of those people who don't even like hidden pockets
03:40 PM roycroft: i *know* they're there ;)
03:40 PM travis_farmer[m]: even filled, they look like hell
03:40 PM roycroft: but that's my problem, and i don't wish to project that problem on anyone else
03:41 PM roguish[m]1: wow, we've got 1.4 inch rain today. since midnight.
03:41 PM roycroft: dominos are awesome, though
03:41 PM roycroft: i mean, really awesome
03:41 PM roguish[m]1: ok, what's a domino in wood working
03:41 PM roycroft: a proprietary fastener system from festool
03:42 PM * travis_farmer[m] can't afford festool
03:42 PM roycroft: https://www.festoolusa.com/products/domino-joining-system/domino-joining-machines/576423---df-500-q-set-us
03:42 PM roycroft: sit down before you click on that
03:43 PM roycroft: there's some serious sticker shock there
03:43 PM * roycroft can't afford not to use festool
03:43 PM roycroft: i buy almost all my festool machines from festoolrecon.com, though
03:43 PM roycroft: and i get 25-30% off getting the gear there
03:43 PM roycroft: it's still bloody expensive, but it's worth it
03:43 PM roguish[m]1: ok, i see it now...
03:43 PM travis_farmer[m]: i think my heart stopped.....
03:44 PM travis_farmer[m]: nope, there it goes :-)
03:44 PM roycroft: the machine makes a plunge cut, but the cutter oscillates horizontally
03:44 PM roycroft: so it cuts a wide slot
03:44 PM roycroft: very precisely
03:45 PM roycroft: so in essence it's a loose tenon system with a machine that cuts the mortises easily and very accurately
03:49 PM roycroft: travis_farmer: festool abrasives are the most cost effective i've ever used - they last way longer than any other brand that i've tried
03:49 PM roguish[m]1: gotta figure out the one corner cabinet.
03:50 PM roycroft: that $500 sander is expensive up front, but when you can get 95+% extraction that saves a lot of cleanup time, and the savings on abrasives makes up for the cost of the machine after a while
03:52 PM ZincBoy[CAON][m]: Expensive tools are only expensive once. Cheap tools keep costing you over and over. If you are using something every day, the expensive tool is usually cheaper.
03:52 PM ZincBoy[CAON][m]: That being said, I stand by my $20 angle grinders that I throw out when they die 🙂
03:52 PM bjorkintosh: harbor freight, ZincBoy[CAON][m]?
03:53 PM travis_farmer[m]: when i work, i only get $14 per hour, gross income... unless that changes, i will have to make due with the cheaper tools :-(
03:55 PM ZincBoy[CAON][m]: Princess Auto. Canada's answer to Harbor Freight.
03:56 PM ZincBoy[CAON][m]: I could use their lifetime warrantee but I feel bad when it is my abuse that kills them.
03:56 PM roycroft: i buy $20 hf angle grinders all the time
03:56 PM roycroft: and i burn up $20 hf angle grinders all the time
03:57 PM roycroft: because i've purchased expensive angle grinders before, and they don't last that much longer than the cheap ones
03:57 PM ZincBoy[CAON][m]: The flap disks are almost more than the grinder...
03:57 PM roycroft: i think it's the nature of the work - when you're spewing metal dust and abrasives all over the place, that stuff is going to get inside the grinder
03:57 PM roycroft: and it's hard to keep it out
03:59 PM ZincBoy[CAON][m]: I have a bosch 5" grinder that I haven't been able to kill yet. Still not worth the 10x price premium.
04:01 PM bjorkintosh: <ZincBoy[CAON][m]> I could use their lifetime warrantee but I feel bad when it is my abuse that kills them. They count on your feeling bad not to collect!
04:02 PM bjorkintosh: but it's part of their business model. they know they make crappy products. so it's all neatly incorporated.
04:03 PM ZincBoy[CAON][m]: Yes, but I use the warrantee enough for other things that are actually bad that I don't for the stuff that is my fault.
04:03 PM roycroft: hf don't offer a lifetime warranty
04:03 PM Tom_L: the life of the tool you just bought
04:03 PM roycroft: their warranty is 90 days or less on the $20 grinders
04:04 PM roycroft: mine ususally don't die that soon, but they all die prematurely
04:39 PM mystamo[m]: Zinc what parts of Ontario in in ?
04:39 PM mystamo[m]: s/in/you/
05:02 PM mrec: Lcvette[m]: the centerdrill seems to be fine, I need to update my g-code to use it. I only made around 37 parts so far I need 63 more.
05:02 PM mrec: I did not expect that the stepdrill will be such a failure - but it was.
05:03 PM mrec: a regular drill also did not work
05:10 PM roycroft: step drills can be useful for some things, but complete failures for others
05:10 PM unterhaus: mine just took the chuck right off the drill press
05:10 PM unterhaus: gently though
05:11 PM unterhaus: I haven't had a lot of luck with this drill press, I guess I'm just used to industrial versions
05:14 PM roycroft: i'd pull the chuck out, scrape the spindle with a taper scraper, clean it up really well, clean up the taper adapter on the chuck really well, then reinstall the chuck and give it a good, but not excessive *thwap* with a wooden mallet to seat it well
05:19 PM roycroft: it might also be interesting to clean the spindle and the chuck taper well, coat the chuck taper with prussian blue, insert it into the spindle and give it a couple twists
05:19 PM roycroft: if you don't get good contact then you have a problem
05:26 PM mrec: I put it into the CNC the problem is that the tip is not sharp enough to get smoothly into the sheet metal
05:27 PM ZincBoy[CAON][m]: Hamilton side of the GTA
05:27 PM roycroft: the tip of the step drill?
05:27 PM roycroft: i've never attempted to start a hole with a step drill
05:27 PM mrec: so I'd hae to use a center drill .. but for 3/5mm holes the center drill seems to be the best option so far
05:27 PM roycroft: i always drill a pilot hole first
05:27 PM ZincBoy[CAON][m]: I usually pre-drill before using a step drill. They really don't start holes well.
05:27 PM mrec: not worth it in my case..
05:28 PM roycroft: i don't think a step drill is designed to start holes
05:28 PM roycroft: they should just make the tip totall blunt, instead of teasing people with a semi-pointy appearance
05:29 PM ZincBoy[CAON][m]: Step drill + impact driver is the best thing for making round holes in sheet metal up to 1/4"
05:29 PM mrec: what stops a centerdrill to have a tip like a center drill?
05:29 PM mrec: ups
05:29 PM roycroft: but even so, in sheet metal a step drill tends to deform the sheet a lot
05:29 PM mrec: step drill*
05:30 PM mrec: I used a step drill for my cnc controller housing it worked well
05:30 PM roycroft: the geometry of the tip of a step drill doesn't lend itself to starting holes well, but if it were sharpened well it could do a semi-decent job
05:30 PM mrec: that housing is made of thin aluminum sheet
05:30 PM roycroft: but the tips of step drills are never sharp
05:30 PM ZincBoy[CAON][m]: I have at least one step drill with a sharp point that will start a hole. It was also $100. Most of the cheap ones are not sharp.
05:30 PM roycroft: they're just pointy-like
05:31 PM roycroft: in thin sheet metal i prefer using a chassis punch when making large-ish holes
05:31 PM roycroft: that can be expensive, and not always possible, of course
05:33 PM ZincBoy[CAON][m]: The step drill is needed to make the hole for the punch pull stud 🙂
05:33 PM mrec: does anyone know a good source/book for learning about dies and punches?
05:35 PM roycroft: i use a twist drill to drill the pilot holes for my chassis punches
05:35 PM mrec: that feederfinger I'm making out of copper sheet requires 9 steps to make
05:35 PM mrec: https://i.snipboard.io/cYuAJW.jpg
05:35 PM mrec: it's quite complex but I can make it
05:35 PM unterhaus: prussian blue on the spindle is a good idea. There aren't any obvious dings on either spindle or chuck
05:37 PM roycroft: if it's a cheap drill press the spindle taper might not be accurate
05:38 PM roycroft: you can get a spindle reamer, but using one by hand could end up introducing some (additional) runout, while allowing the taper adapter to seat better
05:39 PM roycroft: but see what you have going first
05:39 PM roycroft: it always helps to diagnose the problem before trying to fix it :)
05:45 PM Tom_L: 45 caliber works pretty well for holes in sheetmetal too
05:45 PM Loetmichel: depends on the sheet metal
05:45 PM Tom_L: depends on the slug too
05:46 PM Loetmichel: over here in germany even 1" ship steel is called "Blech" in some companies.
05:46 PM Loetmichel: (Blech= german for sheet metal)
05:47 PM Loetmichel: I am pretty sure the 50mm ship hull steel will stop even a high velocity .45
05:48 PM Loetmichel: s/1"/2" sorry typo
06:00 PM roycroft: i usually think of sheet metal as coming in gauge size, and the gauge charts in this country generally go up to 3ga, which is roughly 1/4"/6mm
06:00 PM roycroft: anything thicker than that i think of as "plate", not "sheet metal
06:00 PM roycroft: "
06:00 PM roycroft: and even 1/4" is commonly sold as, and referred to as plate
06:01 PM roycroft: but i suppose it all depends on context
06:01 PM Loetmichel: roycroft: yeah, same here. but that is relative. If you build supertankers i suppose 50mm is really "sheet" material in comparsion to the beasts of i-beams they use for structural
06:02 PM Loetmichel: indeed. context is important.
06:26 PM roycroft: my layout gage has arrived
06:26 PM roycroft: it is japanese, and what is interesting is that us customary (inch) scale is spot on, but the metric scale is off by 0.05mm
06:27 PM roycroft: since i'll be using it for woodworking (which is what it was designed for), that's a margin of error i think i can live with
06:28 PM XXCoder: weird
06:29 PM roycroft: yeah, and both the us customary and metric scales are etched into the same part
06:29 PM roycroft: as are both the vernier scales
06:29 PM roycroft: so it can't be a factory defect
06:30 PM roycroft: it's a master part defect, unless the scales or verniers are not etched at the same time
06:32 PM XXCoder: i find that weird because japan is meteric
06:32 PM XXCoder: wouldnt they check meteric
06:32 PM roycroft: https://matsui-seimitsu.co.jp/products/scriber_gauge.html
06:32 PM roycroft: that's what i have
06:33 PM roycroft: except mine has a us customary scale at the top and metric at the bottom
06:33 PM roycroft: but yeah, i'd think they would calibrate to metric
06:33 PM roycroft: like i said, though, 0.05mm is something i can live with
06:33 PM roycroft: and even if i couldn't, it's a consistent offset, so i could compensate
06:38 PM roycroft: i'll be using this with both unit systems, which is why i got it with both
06:43 PM XXCoder: yeah
