01:33 AM randy: morning
02:07 AM Deejay: moin
02:23 AM Loetmichel: Mornin'. **GNHIHIHIHI** More than an hour late at work. Slept in a bit. Boss Still not there. WIN! :D
02:23 AM Deejay: yay
02:23 AM Deejay: morning lm
02:43 AM roycroft: i hear that your country will be imposing a speed limit on all autobahns, so you can use that as your excuse for being late, should your boss every be awaiting your arrival
03:16 AM Loetmichel: roycroft: that will happen as soon as texas gets british level of Weapons laws.
03:17 AM Loetmichel: probaly the latter is more likely.
04:26 AM Tom_L: morning
04:37 AM randy: Loetmichel: because of "STREIK!!!" or "ZEITUMSTELLUNG!!" or both? :)
05:29 AM JT-Cave: morning

05:32 AM boostedcabbage[m: what am i doing wrong with the tool here? i've drawn in yellow how i'd like to tool to sit. you can see the new tool T11(a TCMT 2151) i've added. am i getting the angles or tool position/orientation wrong?

06:58 AM AlexmagToast5525: Hi Guys, I want to tell you about my latest Projekt. It is an LinuxCNC IO expansion using an Arduino. With my software you can basicly have as many Buttons, Poti's or LED's as you want. (or your arduino can handle 💁♂️ )... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/97b482478af9cdd6228ab74d00b583859ff75170>)
06:59 AM AlexmagToast5525: s/I just added WS2812 support, so now you can truly have as many RGB LEDs as you want.//
07:50 AM * Tom_L wonders where mesact2 left off

08:17 AM Rowow5457[m]: Is the error code simply asking me to rename the file or is there something else going on
08:18 AM Tom_L: seems it want's you to rename them
08:21 AM * Rowow5457[m] uploaded an image: (1766KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/pfgdlWuwqJdrbtIGPVWypmXX/PXL_20230327_131948027.jpg >
08:21 AM Rowow5457[m]: I don't see any such file in the location
08:22 AM Tom_L: /usr/share/doc/linuxcnc and .../linuxcnc-uspace are directories
08:23 AM Tom_L: maybe the docs weren't built
08:23 AM Rowow5457[m]: Sorry I don't understand what directory means. Is that the same as a file location?
08:23 AM Tom_L: yes
08:24 AM Rowow5457[m]: Should I try installing it without docs from the beginning
08:24 AM Tom_L: doesn't look like they were built
08:26 AM AlexmagToast5525: when i was compiling linuxcnc i had to remove the doc settings in the rules file.
08:27 AM Rowow5457[m]: What's the difference between docs and no doc
08:27 AM Tom_L: you're building 2.9?
08:27 AM AlexmagToast5525: https://youtu.be/2SSzstLp5cs?t=242
08:27 AM AlexmagToast5525: This is how i did it.
08:28 AM Rowow5457[m]: Yes
08:28 AM Tom_L: the switch 'no-docs' doesn't compile the docs but just the code so it takes alot less time to generate
08:29 AM Tom_L: 2.9 afik is still 'master' and can be in various states of broken as it gets worked on
08:45 AM Rowow5457[m]: Installing without the docs worked 😄
08:45 AM Rowow5457[m]: Installing the final packages now

08:47 AM Rowow5457[m]: Works!!! Thank you so much
08:47 AM Rowow5457[m]: Last thing is to figure out the missing tooth encoder. Hopefully it's as simple as adding that one line to the hal file
08:53 AM * Rowow5457[m] uploaded an image: (1838KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/qfvTSumzfKzrqPEJsojlRZox/PXL_20230327_135121089.jpg >
08:53 AM Rowow5457[m]: So so close.....
08:53 AM Rowow5457[m]: After running the step configuration gui I get this when trying to start it
08:55 AM rmu: Rowow5457[m]: you need to install rt preempt kernel
08:55 AM Tom_L: yeah
08:55 AM Tom_L: the kernel you're running is probably the standard one that comes with debian
08:56 AM Tom_L: open synaptic package manager and look for a preempt-rt kernel
08:56 AM Tom_L: hopefully you don't have to build one
08:56 AM rmu: linux-image-rt-amd64
08:57 AM randy: fyi: with "uname -a", it should state "PRREMPT_RT"
08:57 AM randy: PREEMPT_RT

08:58 AM rmu: use this one https://packages.debian.org/buster/linux-image-rt-amd64 if possible, newer ones (5.x and 6.0.x) from debian don't work as well currently
08:58 AM Rowow5457[m]: Did I do it right
08:58 AM Rowow5457[m]: I can't find any preempt-rt kernal
08:58 AM rmu: Rowow5457[m]: linux-image-rt-amd64
09:00 AM Rowow5457[m]: Sorry I don't understand how to install this
09:01 AM rmu: search for linux-image-rt-amd64, that should be the "standard" rt preempt kernel
09:01 AM rmu: (standard for your debian version)
09:04 AM Rowow5457[m]: I tried "sudo apt-get linux-image-rt-amd64" and after installing still have the same error when booting Linux cnc
09:04 AM rmu: what does uname -a say now?
09:05 AM rmu: uname -r

09:06 AM Tom_L: still the standard kernel
09:06 AM Rowow5457[m]: 5.10.0-21-amd64
09:06 AM rmu: you need to reboot the PC

09:08 AM Rowow5457[m]: Error has changed now
09:08 AM Rowow5457[m]: The default stepconfig wizard works!!!
09:09 AM Rowow5457[m]: Just the one I did changes to my prior settings doesnt
09:09 AM Tom_L: line 21 or thereabouts in the hal
09:10 AM Tom_L: spindle-at-speed _may_ be spindle.0.at-speed now
09:11 AM Tom_L: http://linuxcnc.org/docs/2.9/html/man/man9/motion.9.html#SPINDLE%20PINS
09:11 AM Tom_L: spindle.M.at-speed IN BIT
09:15 AM Tom_L: multiple spindle support was added
09:17 AM Rowow5457[m]: I'm not able to find any such line
09:18 AM Tom_L: pyvcp_options.hal
09:18 AM Tom_L: https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/xoXStYeugPvrBuyMstXOsTDg/PXL_20230327_140653404.jpg
09:19 AM Tom_L: line 21
09:20 AM Rowow5457[m]: I went through the GUI and found I didn't click the "spindle at speed" box, after clicking it works now!
09:33 AM Rowow5457[m]: Is the only way Linux cnc can thread is by having control of the spindle via vfd? Is there a way to get it to be a electronic gearbox, for the motors to sync with the spindle instead
09:33 AM rmu: Rowow5457[m]: AFAIK that works, you need at least an index pulse from the spindle
09:34 AM rmu: then Z-Axis moves synced to spindle. if it is accurate enough to cut threads... you will have to try
09:35 AM rmu: s/if it is/is it/
09:36 AM Tom_L: JT-Cave, looks good so far
09:39 AM Rowow5457[m]: When I try a g33 command it says "spindle not turning in g33"
09:39 AM Rowow5457[m]: It shows the spindle speed and I added the missing tooth index line in the hal file
09:39 AM * Rowow5457[m] uploaded an image: (1236KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/SgtdktEtHwbQtisxQhbkiAZw/PXL_20230327_143840478.jpg >
09:41 AM Tom_L: 2 things. you may need to add a 'near' component for the spindle-at-speed
09:41 AM Tom_L: and you need to add a hal line for the index pulse
09:42 AM Tom_L: net spindle-index-enable <=> hm2_[HOSTMOT2](BOARD).0.encoder.01.index-enable
09:42 AM Tom_L: net spindle-index-enable <=> spindle.0.index-enable
09:42 AM Tom_L: similar to that
09:42 AM Tom_L: (that's the one from my config)
09:42 AM Tom_L: it's a bidirectional signal
09:43 AM Tom_L: as the index needs to be reset every rev and that takes care of it
09:43 AM Tom_L: at least that's my understanding of it
09:46 AM Tom_L: G33 is expecting to see the pulse and aparently it doesn't see it
09:46 AM Rowow5457[m]: I checked the hal file and when I went through the stepconfig wizard it removed my
09:47 AM Rowow5457[m]: setp encoder.1.missing-teeth 1
09:47 AM Rowow5457[m]: Line. I booted Linux again and it shows my rpm being twice the number it was before
09:47 AM Tom_L: i don't know about the missing teeth thing... maybe andy does
09:48 AM Tom_L: the question is though, is the commanded rpm close to the actual?
09:50 AM Rowow5457[m]: This is my first time threading so I'm not sure how it works
09:50 AM Rowow5457[m]: How do I command the rpm
09:50 AM Tom_L: S50 M3 from the MDI <> 784.8 in your pic
09:51 AM Tom_L: scale is off
09:52 AM Rowow5457[m]: "s50 M3 784.8"
09:52 AM Rowow5457[m]: M code is greater than 199 m3785
09:53 AM Rowow5457[m]: I also set the missing tooth number to 2 and that got the rpm back to 784
09:53 AM Tom_L: S50 M3 is the commanded rpm... 784.8 is the result i see in the spindle speed box
09:53 AM Rowow5457[m]: Even though it should only be 1
09:54 AM Tom_L: S50 sets the speed, M3 turns the spindle on
09:55 AM Tom_L: (clockwise)
09:55 AM Rowow5457[m]: Theres no control over the spindle speed, I'm currently switching on the lathe manually with a switch.
09:56 AM Rowow5457[m]: The spindle on button on the GUI is missing so I tried to make it think the spindle is on
09:56 AM Tom_L: ok
09:56 AM rmu: Rowow5457[m] | How do I command the rpm
09:56 AM rmu: and
09:56 AM rmu: Rowow5457[m] | Theres no control over the spindle speed, I'm currently switching on the lathe manually with a switch.
09:56 AM Tom_L: :)
09:56 AM rmu: doesn't really make sense does it
09:57 AM JT-Shop: wow I got an email from chevrolet.com :)
09:57 AM Tom_L: holy crap batman!
09:58 AM Tom_L: hope it didn't start out: we regret to inform you...
09:58 AM rmu: i get emails from "unilever global sourcing" about weekly, they want to buy a truckload of some sort of self priming food-grade massive pump
09:58 AM Tom_L: rmu, he's expecting something..
09:58 AM rmu: no idea how that pump-scam is supposed to work
09:59 AM JT-Shop: started out Congratulations
09:59 AM Tom_L: :)
09:59 AM Tom_L: it's a boy
09:59 AM travis_farmer[m]: 🙃
09:59 AM JT-Shop: says Order Accepted
10:00 AM Tom_L: ^^ blue for the slower croud
10:00 AM JT-Shop: then three more milestones before ready for transport
10:00 AM JT-Shop: lol, of course it's a boy
10:01 AM Rowow5457[m]: Sorry for the miscommunication. I'm not sure the correct terminology but I think what I am trying to do is a electronic gearbox. I'm trying to thread with no vfd. So it threads based off the rpm of the motor and uses a missing index encoder to measure the rpm. It's reading the rpm fine but the "spindle at speed" button is red. And when I do a g33 command it says "spindle not turning" even though it's reading a rpm
10:01 AM Tom_L: Rowow5457[m], try satisfying the 'at-speed' condition
10:01 AM Tom_L: use a 'near' component for that
10:02 AM Rowow5457[m]: It's green when the spindle is at 0
10:02 AM rmu: or just set spindle-at-speed to 1
10:02 AM Tom_L: or that

10:05 AM Tom_L: setp
10:06 AM Tom_L: not net
10:06 AM rmu: and if it is connected to some writer (output-pin) you will have to unlink that connection first
10:07 AM Rowow5457[m]: It boots now but still same issue of "spindle not turning"
10:09 AM rmu: is your spindle.0.speed-in connected to your encoder output?
10:10 AM rmu: encoder.1.velocity or something like that?

10:11 AM Rowow5457[m]: This line or another one
10:12 AM Tom_L: net spindle-velocity <= hm2_[HOSTMOT2](BOARD).0.encoder.01.velocity
10:12 AM Tom_L: net spindle-velocity => spindle.0.speed-in
10:14 AM rmu: "printscreen" key usually starts a screenshot-tool, matrix can be easily used from the webbrowser, also you could copy/paste text

10:14 AM Rowow5457[m]: After adding those two lines to the hal I get this error
10:14 AM Tom_L: Rowow5457[m], that was from my config...
10:14 AM Tom_L: match it to your encoder syntax
10:15 AM Rowow5457[m]: I'll setup matrix definitely something I've been meaning to do in a while
10:16 AM Tom_L: net spindle-velocity encoder.0.velocity => spindle.0.speed-in
10:16 AM rmu: Rowow5457[m]: I assumed you are on matrix because your Nickname has [m] appended, at least I in IRC see it that way
10:17 AM Rowow5457[m]: No I'm on discord
10:17 AM rmu: this https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/vEoeHIWcQvrfczVURUXqKpmx/PXL_20230327_150937790.jpg doesn't show complete lines, if spindle-velocity is connected to something

10:28 AM Rowow5457[m]: I'ma grab some lunch and maybe my head will clear
10:29 AM rmu: actually I don't have a CNC lathe, so i can't really help there
10:29 AM Tom_L: me either but the mill spindle should work the same
10:33 AM JT-Shop: I just did a test engraving at 0.030" deep... I think roycroft said to seal it with shellac before painting the letters?
10:33 AM JT-Shop: I don't think I'll need to go that deep in the brass...
10:34 AM Tom_L: i used krylon on mine and it has suvived a 'shop' environment fine
10:34 AM Tom_L: iirc i went either .020 or .030 deep
10:34 AM Tom_L: i somewhat tested as i made mine
10:35 AM Tom_L: tried a couple depths and since i was the only one to see it, left it
10:36 AM Tom_L: done on the sherline, it wasn't perfectly flat but the top were deeper: http://tom-itx.no-ip.biz:81/~webpage/cnc/pendant/pendant2.jpg
10:37 AM Tom_L: but my tip wasn't as wide as yours
10:37 AM Tom_L: 60deg iirc
10:39 AM Tom_L: .020 deep
10:39 AM JT-Shop: my tip is 0.030" wide
10:40 AM Tom_L: yeah i'd have to go look but i think mine are .010
10:40 AM Tom_L: near as i can find, the top txt is either .020 or .025 deep
10:40 AM Tom_L: meh, start shallow
10:41 AM Tom_L: you can always run it again deeper

12:20 PM Tom_L: looks good
01:54 PM JT-Woodshop: thanks
01:59 PM -!- #linuxcnc mode set to +v by ChanServ
02:10 PM JT-Shop: oh and I found my flashlight I lost a few weeks ago...
02:34 PM boostedcabbage[m: i think i was getting a weird path because i had g42 instead of g41. might actually have the tool correct
02:35 PM boostedcabbage[m: if the angles are relative to Z, why is a quadrant required at all?
02:35 PM boostedcabbage[m: must be something i'm missing
02:40 PM boostedcabbage[m: i'll do the operation twice from the same location with it on and off. should show visual difference
02:52 PM * JT-Shop wonders what we are talking about...
02:53 PM boostedcabbage[m: i'm trying to setup cutter comp to work with the tool used like this:
02:53 PM boostedcabbage[m: https://cdn.discordapp.com/attachments/970073318810075149/1089859290208149554/Screenshot20from202023-03-272006-25-53.png
02:54 PM JT-Shop: is this a lathe?
02:54 PM boostedcabbage[m: yes
02:54 PM JT-Shop: what is important on a lathe is the control point

02:55 PM boostedcabbage[m: it should be a g41 i guess. here's what i get with and without compensation right now
02:55 PM boostedcabbage[m: what do you mean by control point?
02:56 PM JT-Shop: http://linuxcnc.org/docs/stable/html/lathe/lathe-user.html#_tool_path
03:04 PM boostedcabbage[m: so the control point should follow the programmed path without comp on
03:04 PM boostedcabbage[m: and also how i should zero the axes
03:04 PM boostedcabbage[m: home*
03:12 PM JT-Shop: home on a lathe is xz away from the spindle
03:14 PM JT-Shop: https://www.youtube.com/watch?v=G4-lUNa0CpY
03:14 PM JT-Shop: that's why you want to check carefully your offsets
03:15 PM JT-Shop: https://www.youtube.com/watch?v=VmRUJk0ptN4
03:16 PM boostedcabbage[m: indeed. i've written some gcode in the past that kissed the chuck a few times. fortunately it's a very small lathe with little inertia. but still not good
03:16 PM JT-Shop: that's how I touch off Z to the fixed point
03:16 PM Tom_L: JT-Shop, ... flashlight... your new one?
03:16 PM JT-Shop: then all tools are the same offset and only one needs to be touched off to the material
03:16 PM JT-Shop: no
03:17 PM JT-Shop: I prob dropped the new one when I was intoxicated and fell down in the hotel parking lot
03:17 PM Tom_L: lost?
03:17 PM JT-Shop: I assume someone picked it up
03:18 PM Tom_L: oh, new home
03:19 PM Tom_L: that was kind of you to buy a total stranger a nice flashlight

03:19 PM boostedcabbage[m: does my tool definition look correct? T11 P11 D0.015625 I+90 J+30 Q6 -- cutter has 1/64 radius
03:21 PM JT-Shop: if it looks correct on the plot it's correct... seems correct

03:26 PM boostedcabbage[m: it seems to stop short in the Z the entire cutter radius from the programmed path. i think that's correct
03:30 PM Tom_L: depends on several things. how it is defined in the cad cam and whether the radius is compensated for in the cad or not etc
03:31 PM boostedcabbage[m: i'm just writing straight gcode for this
03:32 PM boostedcabbage[m: i actually need to learn and use some cam solution in the future
03:32 PM Tom_L: do you touch off the tip?
03:32 PM Tom_L: if you hand code it likely won't be as accurate with radius tools
03:32 PM boostedcabbage[m: indeed
03:33 PM Tom_L: if you're doing a straight cut in either axis it may be ok
03:33 PM Tom_L: but that's about it
03:34 PM boostedcabbage[m: but i should still be able to hand code straight cuts and arcs with comp on and have accuracy, correct?
03:35 PM boostedcabbage[m: assuming my tool is defined correctly and i use g41/g42
03:37 PM Tom_L: test it and see
03:39 PM Tom_L: i've only used my lathe cad cam a few times and once you entered the tool geometry it compensated for it so i didn't have to worry with it
03:39 PM Tom_L: and i don't have a cnc lathe but have run them

03:44 PM boostedcabbage[m: the first G01 X-0.190 seems a little strange. i think i'm just going to home this away from the part, and let it gradually cut that profile and see what we get 🙂
03:45 PM Tom_L: what are the green? lines toward the bottom?
03:45 PM Tom_L: another tool?
03:46 PM boostedcabbage[m: jogs
03:46 PM Tom_L: ok
03:46 PM Tom_L: make sure it jogs away from the material :)

03:47 PM boostedcabbage[m: actually needs to be a g03
03:47 PM Tom_L: makes a little more sense
03:47 PM boostedcabbage[m: yeah.. i just set a loop, and it'll gradually walk into it. be cutting air for a while
03:49 PM boostedcabbage[m: i'm still not sure why that first G01 X-0.190 angles in like that
03:49 PM boostedcabbage[m: the rest don't
03:49 PM boostedcabbage[m: maybe it just paths that way because of the comp
03:49 PM Tom_L: could be
03:51 PM Tom_L: what lathe is this?
03:52 PM boostedcabbage[m: a 7x10 hf pile i converted

03:54 PM Tom_L: i've got an old sears atlas manual that's nearly worn out
03:55 PM boostedcabbage[m: some day i'll own a "real" lathe.. hehe
03:58 PM boostedcabbage[m: it seems to me like that first move will gouge if i were to set my Z home right against the part
03:58 PM boostedcabbage[m: what am i even talking about. that's not what i would want to do
03:59 PM boostedcabbage[m: Z home should be -0.824 from the part Z edge
03:59 PM roycroft: my lathe is probably more worn than yours, tom_l
03:59 PM roycroft: at least close to the chuck
04:00 PM boostedcabbage[m: roycraft: do you have any idea why my first X move angles in? is this just something cutter comp does?
04:01 PM Tom_L: turn cutter comp off and see
04:02 PM boostedcabbage[m: i already know that answer 🙂
04:02 PM roycroft: no, i don't know why that would be, boostedcabbage
04:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Z_Axis_Pulley.jpg
04:03 PM Tom_L: roycroft, i wouldn't bet on it
04:03 PM boostedcabbage[m: is that a collet style lathe?
04:03 PM Tom_L: no
04:04 PM boostedcabbage[m: i saw a collet style locally for pretty cheap, but thought it was strange not being able to pass things through the spindle
04:04 PM boostedcabbage[m: i guess it depends on what you need to do
04:05 PM Tom_L: i've had that a good 30-40 yrs
04:05 PM Tom_L: and it was used when i got it
04:06 PM Tom_L: but i don't use a lathe alot
04:17 PM roycroft: my tailstock has a cam lock to position it on the ways
04:17 PM roycroft: if i adjust it so that the camlock engages on the far end of it, it doesn't even start to grab near the chuck
04:17 PM roycroft: i have to reach underneath and tighten the nut
04:17 PM roycroft: i haven't measured the wear, but it's several thousandths
04:18 PM roycroft: i'd say it's probably at least similar to yours in terms of wear
04:19 PM roycroft: this is a big reason why i've been thinking about getting a new lathe

05:12 PM JT[m]: Need an inch
05:13 PM Tom_L: i'm sure you'll find it
05:13 PM XXCoder: looks like can remove some top wood
05:13 PM XXCoder: unless that destabilizes it too much?
05:13 PM Tom_L: lower the tire pressure
05:14 PM XXCoder: I suppose can remove from top and attach to some spot under it
05:19 PM roycroft: that's not your new thicknesser, is it?
05:19 PM XXCoder: looks like bandsaw
05:20 PM roycroft: oh, bandsaw
05:20 PM roycroft: ok, that makes more sense
05:20 PM roycroft: i didn't see the first picture
05:20 PM XXCoder: dunno if im right though
05:20 PM roycroft: i'd uncrate it in front of the gantry crane

05:42 PM JT-Woodshop: prob redo the rigging now it's sitting on cribbing
05:43 PM XXCoder: ok im bit confused
05:43 PM XXCoder: your shuipping it out or in?
05:43 PM JT-Woodshop: just received it
05:43 PM JT-Woodshop: a new bandsaw
05:43 PM JT-Woodshop: only 21" to the ground!
05:44 PM XXCoder: lol ok

05:50 PM boostedcabbage[m: so this is looking better. it's showing the tool i defined
05:50 PM boostedcabbage[m: makes the compensation much more clear visually
05:51 PM JT-Woodshop: well that was very interesting for sure
06:19 PM JT-Woodshop: everything outdoors is put away so time to call it a night
06:19 PM XXCoder: nice
06:20 PM JT-Woodshop: I'm a tired puppy now, been a bit sick so not a lot of energy last couple of days
06:48 PM unterhaus_: When I got my bandsaw it only fell over once
06:49 PM XXCoder: wouldnt it shatter cast iron parts

06:57 PM boostedcabbage[m: cutter comp seems to be working
06:57 PM boostedcabbage[m: not even bumping into the shoulder 🙂
07:22 PM XXCoder: https://youtu.be/hM02oN0vDpM
07:22 PM XXCoder: interesting. guy makes mininmicrometer
07:24 PM XXCoder: guy uses something like reamer but looks veru different
08:18 PM Tom_L: cute
08:18 PM Tom_L: wouldn't be my 'goto' mic
08:20 PM bjorkintosh: why not? too fancy for you Tom_L?
08:22 PM Tom_L: no but these are http://tom-itx.no-ip.biz:81/~webpage/cnc/calipers/Mitutoyo_case.jpg
08:22 PM Tom_L: i have some pretty crappy ones too
08:27 PM bjorkintosh: goodness. what are those star components behind the box? how were they made?
08:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/coupler/Coupler_brass5.jpg
08:29 PM bjorkintosh: wow!
08:29 PM Tom_L: coupler on some drill somebody needed one and couldn't order
08:29 PM bjorkintosh: so you cast it?
08:29 PM Tom_L: mill
08:30 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/coupler/Coupler_brass4.jpg
08:30 PM Tom_L: then cut the bottom off
08:30 PM Tom_L: 1/2 at a time so i could still clamp the part in the vise
08:32 PM mrec: Tom_L: did you make the enclosure by yourself?
08:32 PM Tom_L: for the mill?
08:32 PM mrec: for the caliper
08:32 PM Tom_L: oh
08:32 PM Tom_L: i have but i didn't make that one. i did however cut the gage block pocket in
08:33 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/calipers/Mitutoyo2.jpg
08:33 PM Tom_L: made that one
08:33 PM bjorkintosh: fancy.
08:34 PM mrec: I can't say anything about the digital caliper, but the non digital mitutoyo - Mahr (German brand / Chinese made) beats Mitutoyo
08:34 PM Tom_L: mitsutoyo sells that as a kit and some come with the ruler but i didn't get that
08:34 PM Tom_L: that particular mic is the goto around shops here
08:35 PM Tom_L: they however do make a very precision one
08:35 PM Tom_L: for i forget how much but i think around $3k
08:37 PM Tom_L: https://www.mitutoyo.com/products/small-tool-instruments-and-data-management/micrometers/digimatic-micrometers/mdh-micrometer/
08:37 PM Tom_L: i think that is it
08:38 PM Tom_L: no it wasn't quite that much...
08:38 PM Tom_L: https://www.globaltestsupply.com/product/mitutoyo-293-130-10-high-accuracy-digimatic-micrometer
08:39 PM Tom_L: toss that around in your kennedy tool box
08:40 PM bjorkintosh: geezus
08:44 PM Tom_L: mrec, mitsutoyo calipers vary in quality. that particular one with that kit is a much better caliper than the blue one in the other case
08:45 PM Tom_L: i used to have a brown & sharp dial but i gave it to a friend
08:45 PM Tom_L: they were decent
08:45 PM roycroft: mitsutoyo calipers don't really vary in quality, other than standard precision vs. high precision, but there are a lot of counterfeit mitsutoyo calipers roaming around the universe that are crap
08:46 PM roycroft: and amazon make matters a lot worse
08:47 PM roycroft: because if they have 10 vendors selling the same model mitsutoyo calipers, and 5 of them sell the real thing and the other five sell the counterfeit ones, amazon toss them all in the same bin and pull them out randomly to fill an order
08:47 PM roycroft: so even if you know your vendor sells the good stuff, if you order it through amazon you have no way of knowing if it's that vendor's product you're getting
08:48 PM Tom_L: not all of them have the 'absolute' feature
08:50 PM XXCoder: roy yep they put all supposely same items together and get random one, so you could be buying legit one and getting stock from other seller, fake one
08:51 PM Tom_L: i registered mine so i know they are
08:53 PM XXCoder: nice
08:53 PM XXCoder: mines from msc direct
08:54 PM XXCoder: i think
09:04 PM roycroft: i got lucky - mine's the real thing
09:04 PM roycroft: probably because it's a 100mm caliper not 150mm
09:04 PM roycroft: the 100mm is not as poplar, and not as widely counterfeited
09:19 PM Tom_L: i wouldn't mind having a stubby one but i'm not going to buy one
09:20 PM Tom_L: i try to keep a pair by the cad station and have a HF crappy pair i leave in the garage aside from these two
09:21 PM Tom_L: about all i use the HF ones for is sizing a random drill etc that may be laying around
09:22 PM Tom_L: or scoring (i know that's horrible) material blocks to be cut
09:37 PM roycroft: i'm kind of obsessive about measuring tools
09:37 PM roycroft: i have more than probably anyone should have
09:37 PM Tom_L: you could probably say that about any tools you have :)
09:37 PM roycroft: possibly
09:37 PM Tom_L: planes etc
09:38 PM roycroft: not to be defensive, but i do use all of my planes
09:38 PM roycroft: and all my chisels
09:38 PM roycroft: i'm not just a collector
09:42 PM XXCoder: collector that uses all is still a collector ;)
09:42 PM roycroft: i did not say i'm not a collector
09:42 PM roycroft: i said i'm not *JUST* a collector
09:43 PM Tom_L: i caught that
09:43 PM roycroft: i also collect coins and stamps
09:43 PM Tom_L: as a kid i collected stamps
09:43 PM XXCoder: :D
09:43 PM roycroft: the former as an investment as well as a collection
09:43 PM roycroft: the latter just as a collector
09:43 PM Tom_L: and a few odd coins
09:44 PM roycroft: i was a coin collector when i was a lad
09:44 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/penny_heads.jpg
09:44 PM roycroft: but i collected mainly us coinage by year, mostly modern (at the time) coins
09:44 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/penny_tails.jpg
09:45 PM roycroft: currently i'm collecting type sets, in uncirculated or proof condition
09:45 PM Tom_L: those are a dying thing
09:46 PM Tom_L: damn, finally found the first box i did http://tom-itx.no-ip.biz:81/~webpage/temp/caliper.jpg
09:46 PM roycroft: i've also been collecting us silver proof sets for 20-ish years
09:47 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/misc/caymen_heads.jpg
09:47 PM roycroft: i don't remember the exact year i started that, but the set is worth more than i paid for it, adjusted for inflation, so i'm doing ok
09:47 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/misc/caymen_tails.jpg
09:47 PM Tom_L: flipside is more interesting to me
09:47 PM roycroft: nice caliper case
09:47 PM Tom_L: i ran out of walnut on the 2nd one
09:51 PM Tom_L: those finally gave out on me
