01:13 AM travis_farmer[m]: Well damn... i woke up, took my pills, got my coffee, fired up the computer... it is only a little after 2AM... i thought it was much later
01:23 AM XXCoder: its still am. good morning ;)
01:23 AM travis_farmer[m]: lol, true. G'morning :-)
01:42 AM sensille: is it intentional that mb2hal ini files are not compatible between 2.8 and master?
01:51 AM jpa-: i don't see much difference in docs, what kind of incompatibility?
01:52 AM sensille: still investigating. pin names i think
02:22 AM Deejay: moin
02:23 AM sensille: one pin changed type
02:23 AM sensille: i'll prepare a fix
02:50 AM sensille: PR created
03:21 AM sensille: trying to move to lcnc master ... qtdragon gives be trouble, sometimes segfault in python3 an error in use_pango_font
03:23 AM * sensille tries apt-get upgrade first
03:48 AM * sensille tries 2.9 instead
03:54 AM sensille: same error
04:09 AM travis_farmer[m]: very interesting... found a user comp that uses an ADS1115 ADC... i happen to have a ADS1115 in my collection... i think i will play around with this comp and see if it works. :-) original forum post from here: https://forum.linuxcnc.org/24-hal-components/29294-ads1115-hal-modul-i2c-communication
04:19 AM sensille: lib/python/qtvcp/designer/install_script helped
04:44 AM pere: anyone using mqtt here? would love feedback on <URL: https://github.com/LinuxCNC/linuxcnc/pull/2253 >.
05:16 AM JT-Cave: morning
05:17 AM Loetmichel: hmm, i think i know now why my PC shuts down every now and then. Its NOT the PSU... hat it switch off on me in the middle of looking at a youtube video. reboot showed the CPU at 86°C still.. Just put the blow gun to it... *a coughing fit later* ah, 46°C.. better. Lets see if switches off again. :)
05:32 AM Tom_L: morning
05:32 AM Loetmichel: hi
05:52 AM sensille: the probe/* macros seem totally wrong to me as a (probing) beginner
09:48 AM Tom_L: JT-Cave, did you turn off "use regular expressions" in your 'find' dialog in geany?
09:49 AM Tom_L: figured out it wouldn't search for some things otherwise
09:49 AM Tom_L: [] or () for example
09:55 AM JT-Shop: no, I don't think so
09:58 AM Tom_L: try searching for: hm2_[HOSTMOT2](BOARD).0. or such and see what you get
09:59 AM Tom_L: mine wouldn't find it even if i copied and pasted to the find
10:00 AM JT-Shop: I think pluma is the same way it won't find anything.something
10:01 AM Tom_L: on geany if you turn that off it works fine and also lets you search up as well as down
10:02 AM JT-Shop: a blue C8 was parked next to us when we left Chaumette yesterday and the wife really liked a lot
10:02 AM Tom_L: uh oh
10:02 AM JT-Shop: so now I'm looking for one
10:02 AM * JT-Shop heads to the other shop
11:09 AM * JT[m]1 uploaded an image: (350KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/lOcmhmEmANTpnzuCwjpNGTJc/20230115_110837.jpg >
11:09 AM JT-Woodshop: taking shape
11:11 AM Tom_L: looks nice
11:14 AM XXCoder: ugh couldnt stay sleep
11:14 AM XXCoder: jt nice
11:17 AM JT-Woodshop: thanks
11:19 AM Tom_L: the pattern lines up better on that one
11:23 AM sensille: travis_farmer[m]: which linuxcnc did you try to get mb2hal to work against?
11:25 AM JT-Woodshop: thanks
11:25 AM travis_farmer[m]: 2.9
11:26 AM sensille: i'm trying to move to 2.9 and mb2hal also doesn't work
11:26 AM sensille: still debugging
11:26 AM travis_farmer[m]: Hmmm, interesting
11:37 AM perry_j1987: hows it going guys
11:50 AM * JT[m]1 uploaded an image: (286KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/DSyCLAkRLQeLlPeopPwZvRAk/20230115_114804.jpg >
11:50 AM JT[m]1: Nap time
12:05 PM * roycroft has been working for four hours so far today, and is just now having his morning cappuccino
12:12 PM Bleepshop: JT[m]1: Now you're just showing off. And kinda cruel to do that to a poor defenseless chicken. ;D
12:49 PM JT-Woodshop: warm in here...
01:12 PM XXCoder: nice frank yt video today
01:23 PM * Bleepshop fume "What a PITA"..
01:23 PM Bleepshop: Setting up a new Epson Eco-Tank printer. I've installed Slackware faster. LOL
01:24 PM Tom_L: what you save in ink, you spend in setup time
01:24 PM Bleepshop: You aren't kidding. The black bottle was damn near the size of a beer can. LO
01:25 PM Tom_L: i've got an epson in the attic you can have
01:26 PM Tom_L: the tanks were so small by the time they got done running their test pages they were half empty already
01:27 PM * Tom_L goes back to his orient code after cleaning up the hal file so it's readable
01:31 PM roycroft: i can't afford to use inkjet printers
01:31 PM Tom_L: i just use black on the ones i have
01:35 PM Bleepshop: Not my printer. Just my PITA to set up and have ready for tomorrow morning. LOL
01:41 PM * JT-Shop just noticed he got a $250 raise
01:42 PM perry_j1987: you guys know what might be causing this horizontal bandsaw i got to be cutting crooked after changing blade
01:42 PM bjorkintosh: the guides may be off, perry_j1987.
01:42 PM perry_j1987: blade is cutting out to the bottom right
01:42 PM bjorkintosh: or. worse yet, dull blade
01:42 PM perry_j1987: new blade
01:43 PM perry_j1987: it cut nice before my last blade broke
01:43 PM perry_j1987: replaced it and have not gotten it to cut as nice since
01:43 PM JT-Shop: guides are out of wack
01:44 PM sensille: travis_farmer[m]: did you try to use modbus with VERSION=1.1 in the config? if not, it just crashes early. fix is coming tomorrow
01:46 PM zephyr9900: perry_j1987 the blade may feel sharp but if the teeth on one side are dull it will cut crooked. I have seen it happen on my bandsaw. I tried to cut something too hard for the speed and after that it never cut straight again until replacing the blade.
01:47 PM perry_j1987: ya i got another new blade i could throw in it
01:47 PM travis_farmer[m]: i have not. i will test that tomorrow. where does the version line go? in the main section, or the first transaction?
01:50 PM sensille: main
01:53 PM travis_farmer[m]: ok, will test first thing tomorrow morning :-)
01:56 PM _unreal_: posted the first non cad photos https://github.com/berin-aquaquad/orange-pi-5
02:07 PM * JT[m]1 uploaded an image: (283KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/htdQCOKZupOdOpaQSvMVelzX/20230115_140322.jpg >
02:08 PM roguish[m]: JT-Shop: don't spend the raise all in one place......
02:08 PM travis_farmer[m]: very nice, JT :-)
02:08 PM roguish[m]: JT: yours???
02:09 PM roguish[m]: the popcorn tub?
02:09 PM XXCoder: whats those markings on wood?
02:10 PM XXCoder: curved lines above the firsy red ring
02:10 PM Tom_L: grain
02:10 PM JT-Woodshop: XXCoder, that's the grain of the white oak
02:10 PM XXCoder: ok
02:10 PM JT-Woodshop: roguish[m], yep it's the one I'm making now
02:10 PM JT-Woodshop: popcorn bowl still in the works
02:11 PM Tom_L: you need a matching beer coozie
02:11 PM roguish[m]: very very nice
02:11 PM roguish[m]: new career
02:11 PM JT-Woodshop: thanks
02:11 PM JT-Woodshop: just a fun hobby
02:11 PM * JT-Woodshop doesn't want any new careers
02:12 PM roguish[m]: i'm still practicing my thread milling. an m28x1.5 is tight....
02:12 PM Tom_L: roguish[m], did you find a metric thread mill chart for that?
02:12 PM Tom_L: i have one for imperial
02:13 PM Tom_L: insid & outside
02:13 PM JT-Woodshop: that's a small pitch for that size... camera or something?
02:13 PM * roguish[m] uploaded an image: (550KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/mgJxXeiOaqqCzUIkIeQCdjLM/threading%2028x1.5.png >
02:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/threading/charts/Thread%20Data%20Chart.pdf
02:15 PM Tom_L: funny i had the same one
02:15 PM Tom_L: similar
02:16 PM roguish[m]: for the top of the spindle shaft, as part of the power draw bar system. I can't actually do the spindle. got a good shop to do that. I have to make a tophat, as it's called, to go on the threads. i'm practicing externals, but will have to do an internal eventually.
02:16 PM roguish[m]: Tom_L: maryland metrics is good. i've used them over the years.
02:17 PM roguish[m]: that's image is just a clip of the whole doc.
02:17 PM Tom_L: i figured
02:17 PM Tom_L: i saw who it was
02:18 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/threading/charts/Thread_Maj_int_ext_Diam.pdf
02:18 PM Tom_L: i've used that one for imperial
02:18 PM roguish[m]: right now using fusion360 cam. it's essentially the same as HSMexpress that I have in my SW
02:19 PM Tom_L: huh, i actually made that one for the tooling i have
02:19 PM roguish[m]: using the major diam average, and minor diameter average.
02:19 PM Tom_L: got the data somewhere but forget where
02:20 PM Tom_L: the worksheet is for my cam macro i wrote
02:21 PM roguish[m]: do you have the macro it refers to?
02:21 PM roguish[m]: guess so
02:21 PM Tom_L: yes but it won't do you much good
02:21 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/
02:21 PM Tom_L: threadmill.mcl i think
02:22 PM roguish[m]: wow
02:22 PM Tom_L: heh
02:22 PM Tom_L: works good
02:23 PM roguish[m]: bought one of these for a master...
02:23 PM * roguish[m] uploaded an image: (15KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/UmBmgNTRgtwkdqHZyvrTBFbp/image.png >
02:24 PM Tom_L: i had to do the worksheet because there's a bug in their program on the macro screen: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/macro_screen.jpg
02:24 PM Tom_L: you can't read it :)
02:24 PM Tom_L: so i know the input order
02:25 PM Tom_L: if i change the system colors nothing else is readable
02:25 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/macro_screen1.jpg
02:25 PM Tom_L: fun
02:27 PM Tom_L: i did one internal i had my bud make me a plug to test with since he has thread mics
02:33 PM roguish[m]: i'll give the shop the bearing nut with the spindle shaft to use as a master. already talked with 'em.
02:35 PM roguish[m]: the thread i just finish was way to tight. taking off .004 diameter. now.
02:36 PM Tom_L: check the major D with the specs with a mic, you can come close
02:36 PM Tom_L: to what you need to modify
02:36 PM Tom_L: probably won't take too much on that fine thread
02:42 PM roguish[m]: ok, that's done... very nice fit now.
02:43 PM Tom_L: what did you end up taking off?.. just the .004
02:45 PM Tom_L: the threads look nicer than a tap too
02:50 PM * roguish[m] uploaded an image: (3169KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/ThvUheKzLOIEZwKZwgkLJQru/20230115_124723.jpg >
02:50 PM roguish[m]: yes, .004 off diameter.
02:51 PM Tom_L: nice
02:53 PM JT-Shop: nice
02:54 PM JT-Shop: damn bp mill is not showing up in the file manager...
02:56 PM JT-Shop: used filezilla to transfer the file
02:57 PM Tom_L: right directory?
03:00 PM roguish[m]: i've finally gotten samba working good enough to see the windows network. unfortunately the box i'm on right now, next to the mill, is win 11, and it does not see the linux boxes.......
03:01 PM travis_farmer[m]: thats why i move files with SSH
03:02 PM skunkworks[m]: Roguish (@_discord_781596119976640532:jauriarts.org) make sure you have the right port on samba.. We had issues with windows 10 not seeing our samba shares (we use linux for our file servers)
03:06 PM solarwind_: Anyone know what the countersink angle for standard M3 countersink screws is? https://www.aliexpress.com/item/4000020967604.html?spm=a2g0o.cart.0.0.202b38daqZy7Au&mp=1
03:14 PM solarwind_ is now known as solarwind
03:16 PM roguish[m]: solarwind_: metrics are typically 90
03:16 PM solarwind: thanks!
03:16 PM roguish[m]: americanski are typically 82
03:17 PM CaptHindsight[m]: solarwind: https://en.wikipedia.org/wiki/Countersink
03:17 PM * CloudEvil ponders if someone measured a right angle as 82 degrees in 1900.
03:19 PM CaptHindsight[m]: https://engineersbible.com/countersunk-iso/
03:19 PM roguish[m]: skunkworks: think i fixed it. did not have the old SMB 1.0/CIFS client installed. Win defaults all that old stuff to off, as you know.... anyway, now i can see the linux boxes on network
03:20 PM roguish[m]: well, gotta go make chili for dinner. get it simmering..... for a few hours.
03:20 PM CaptHindsight[m]: https://www.fasteners.eu/standards/ISO/10642/
03:21 PM travis_farmer[m]: chili sounds good, can i come over? ;-)
03:21 PM roguish[m]: bring beer
03:21 PM travis_farmer[m]: Root Beer?
03:21 PM travis_farmer[m]: ;-)
03:21 PM bjorkintosh: real bier
03:22 PM CaptHindsight[m]: https://www.wurthindustry.ca/media/en/pictures/wuerthindustrie/unternehmen/download_center/Broschuere_DIN-EN-ISO_Normung_DE.pdf

03:24 PM Tom_L: nice
03:25 PM CaptHindsight[m]: http://www.sinofastener.com/uppics/2010101610103373772.pdf
03:26 PM CaptHindsight[m]: solarwind: bunch of docs to choose from
03:33 PM solarwind: excellent, thank you!
03:50 PM CaptHindsight[m]: why does google make it so difficult to search for wooden fasteners? https://www.youtube.com/watch?v=PduBjvym1ks
04:35 PM unterhaus_: TIL that my name in French is "cave"
04:49 PM * JT-Woodshop starts another bowl
04:49 PM JT-Woodshop: I suppose I should actually work tomorrow for a while
04:51 PM Tom_L: meh
04:51 PM Tom_L: what would be a good way to visualize an encoder index pulse?
04:51 PM Tom_L: to make sure it is enabled and firing
04:51 PM JT-Woodshop: moment
04:52 PM Tom_L: it's damn short
04:52 PM JT-Woodshop: set index-enable to true
04:53 PM Tom_L: just hardwire it setp?
04:53 PM JT-Woodshop: when the index happens it goes false
04:53 PM JT-Woodshop: for testing?
04:53 PM Tom_L: i have that <=> for spindle sync already
04:53 PM Tom_L: it's bidirectional i think
04:53 PM JT-Woodshop: yep
04:54 PM Tom_L: but i also need it for orient
04:54 PM JT-Woodshop: sets
04:54 PM JT-Woodshop: not setp
04:55 PM Tom_L: i wondered
04:55 PM Tom_L: can that be put in a subroutine so it sets each time it's called?
04:56 PM JT-Woodshop: hmm
04:58 PM JT-Woodshop: orient doesn't set index enable?
04:58 PM Tom_L: i can't find much about that
04:59 PM Tom_L: http://linuxcnc.org/docs/stable/html/man/man9/orient.9.html#FUNCTIONS
04:59 PM JT-Woodshop: yea reading it
05:00 PM JT-Woodshop: it has to use the index to know where 0 is I think
05:00 PM XXCoder: JT-Woodshop: very nice end result
05:00 PM JT-Woodshop: XXCoder, thanks
05:00 PM XXCoder: curious if finish is layered, like paint it on, lightlky sand it, paint again, etc
05:01 PM pcw--home: It look like orient assumes the spindle has been homed
05:02 PM JT-Woodshop: no paint, Tried & True Varnish Oil and rubbed with a cloth in the lathe after each coat
05:02 PM Tom_L: so in the subroutine maybe i should rotate the spindle a couple turns to activate it?
05:02 PM Tom_L: before calling M19
05:02 PM XXCoder: paint isnt really right word, just woke up still lol
05:03 PM XXCoder: had a nap because night was pretty bad
05:03 PM Tom_L: i'm not sure how to activate it...
05:03 PM * JT-Woodshop yields the floor to Tom_L for linuxcnc questions
05:04 PM Tom_L: naw, we need woodworking skilz too
05:05 PM JT-Woodshop: :)
05:06 PM Tom_L: i'm down to testing a line at a time now.. back & forth from office to shop
05:06 PM Tom_L: all my notes are in the ofice
05:06 PM JT-Woodshop: I should hook up the servo I have downstairs and putz with it in a morning over coffee
05:07 PM Tom_L: quite a few signals to figure out
05:07 PM * JT-Woodshop starts to wander back inside
05:07 PM JT-Woodshop: seems anything Michael wrote is brilliant but hard to understand
05:07 PM Tom_L: i had it workin somewhat on the sherline
05:08 PM JT-Woodshop: cool
05:08 PM Tom_L: but i've slept since then
05:08 PM JT-Woodshop: me too
05:10 PM pcw--home: I think orient extracts the fractional part of the turn count and uses that for the absolute 0..360 orient position
05:11 PM XXCoder: gonna love reading code you wrote and not understanding it
05:11 PM XXCoder: I dont understand ldrdat2obj code now lol
05:12 PM pcw--home: (so it assumes the turn count is always correct)
05:13 PM pcw--home: and the the turn count was homed at some point
05:21 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/orient_test/
05:21 PM Tom_L: there are 3 different tests, mdi for M19, normal spindle on, and orient
05:22 PM Tom_L: with toolchange, the pwmgen values aren't changed
05:23 PM Tom_L: however the capture could have missed it
05:43 PM roycroft: xxcoder: https://www.youtube.com/watch?v=2oU6zEZafnQ
05:43 PM XXCoder: looking
05:44 PM XXCoder: nice hal there
05:44 PM * roycroft still has a nth generation photocopy of the original lyons book that he got around 1980
05:45 PM roycroft: i started with 7th edition unix, though, not 6th edition
05:45 PM roycroft: but i have used some v6 machines
05:46 PM roycroft: i don't remember much about it
05:46 PM roycroft: i remember that the shell used a ^ for a pipe, not a |
05:46 PM roycroft: the bourne shell was part of 7th edition
05:46 PM XXCoder: interesting
05:47 PM XXCoder: first *nix os I tried was very early red hat lol
05:49 PM roycroft: yeah, but you're not older than dirt
05:49 PM XXCoder: lol well it wasnt really fun enough so I stopped using it
05:50 PM roycroft: early linux was really horrible
05:50 PM XXCoder: later on my first more common linux was ubuntu. when it was still brown
05:51 PM XXCoder: used it few years when it changed to purple, stopped when they unveiled unity which was wow shit
05:51 PM XXCoder: few years later I started using xfce mint 17. been using it since, now mint 21.1
06:53 PM Tom_L: pcw--home, can i sets spindle.0.index-enable in a subroutine or does it need to go in the main hal file?
06:55 PM pcw--home: you can do it in a subroutine
06:56 PM Tom_L: it only needs done once at startup right?
06:56 PM Tom_L: i addes a 'spindle orient' routine just like homing the axis to the gui
06:58 PM pcw--home: If the encoder never loses a count it only needs to be done once
07:19 PM Tom_shop: so when i: sets spindle-index-enable TRUE from the hal show dialog it works but if i put sets spindle-index-enable TRUE in the main.hal file it says spindle-index-enable not found. same is held true for 'spindle.0.index-enable but that doesn't work anywhere
07:20 PM Tom_shop: and spindle.0.index-enable throws an error from hal show input line
07:22 PM Tom_L: also throws an error if i try putting it in a subroutine
07:23 PM Tom_L: something is messed up with spindle-index-enable. it should be spindle.x.index-enable so you can orient more than one spindle
07:24 PM Tom_L: the only way i was able to get the index pulse to clear was to mdi 'sets spindle-index-enable TRUE' from the hal show cmd line then run a subroutine to rotate the spindle slow
07:25 PM Tom_L: mdi from the main axis screen may have worked but i was already in hal show
07:29 PM roycroft: yay
07:29 PM roycroft: sunset is at 5:00pm tomorrow
07:30 PM XXCoder: roycroft: video was interesting
07:30 PM roycroft: the days are getting longer!
07:30 PM XXCoder: skimmed it a little but pretty good
07:30 PM roycroft: the history of unix is pretty interesting
07:30 PM roycroft: and if you don't know it, it's really fun to learn about it
07:30 PM XXCoder: i was familiar with some of it, that video filled in some stuff
07:30 PM XXCoder: like why unix 6 was open source and teachable and 7 wasnt
07:31 PM roycroft: i've met many of the people mentioned in the video
07:31 PM XXCoder: I wonder what would happen if unix 7 was as fully open as 6 was
07:31 PM * roycroft pretty much grew up while unix was growing up
07:31 PM XXCoder: linux could be just that weird fork by that linux guy
07:31 PM roycroft: and ms-dos may have been a dud
07:32 PM XXCoder: yeah
07:32 PM roycroft: although unix did only run on mini-computers at the time
07:32 PM roycroft: but some sembelence of it could have been ported to the original ibm pc
07:35 PM roycroft: the mark williams company did that, actually
07:35 PM roycroft: they came out with an os named "coherent", which was unix-like os that ran on the pc
07:36 PM roycroft: when i bought my first personal computer, an atari st, i purchased mark williams c for it, which was the first c language compiler for the st
07:36 PM roycroft: and it had a nice unix-like set of utilities that went with the os
07:36 PM roycroft: including a bourne-like shell
07:36 PM XXCoder: nice
07:37 PM XXCoder: I missed a lot of computer tech and consoles growing up
07:37 PM XXCoder: only reason we had atari is because step dad stole it essentally
07:37 PM roycroft: i grew up at the right time for all that stuff
07:37 PM XXCoder: we was very poor back then
07:38 PM roycroft: i had just started high school when the school got its first teletype terminal and access to a time-share computer where i learned to program in basic
07:38 PM XXCoder: I first saw nes console at wa state school for deaf
07:38 PM XXCoder: man I loved marble madness
07:38 PM XXCoder: I didnt have my own pc till I was 16. took me months of saving
07:39 PM roycroft: and i was in high school and college when the early s-100 bus computers came out, like the altos and imsai
07:39 PM XXCoder: nice
07:39 PM XXCoder: there was barely computers at school, but there was enough and I learned.
07:40 PM roycroft: i started using unix in 1977
07:40 PM XXCoder: maconish and windows 3.11 lol fun
07:41 PM roycroft: i'm of the age where i carried a slide rule around with me in high school, but saved my money and got a simple 4-function calculator when i started college
07:42 PM roycroft: i can still use a slide rule, but i cannot caluculate things faster on it than on an electronic calculator
07:42 PM roycroft: and back in the day, i could
07:42 PM XXCoder: my dad had 3 of em. its cool. I think I still have one somewhere
07:42 PM zephyr9900: I used a slide rule in high school for physics and chemistry. I was the only one.
07:42 PM XXCoder: never used it
07:43 PM zephyr9900: There was one kid that bought a 4 function calculator in HS I think he paid over $200 for it.
07:43 PM roycroft: a slide rule was certainly a lot faster than looking up trig tables ina math reference book
07:43 PM zephyr9900: When I started college I bought an HP45
07:43 PM XXCoder: ti-84 for me lol. I still have it
07:44 PM XXCoder: but then I went to college pretty dang late
07:44 PM zephyr9900: Then they said I didn't need to take the slide rule class but I already knew how to use one
07:44 PM roycroft: i couldn't afford an hp45
07:45 PM roycroft: i don't remember what my first calculator was, but it was an off-brand
07:45 PM zephyr9900: yes that was a big investment for me I think it was $400
07:45 PM roycroft: and iirc it still cost me about $100
07:45 PM zephyr9900: Graduated from college in 77 with EE degree
07:47 PM zephyr9900: got a masters in EE in 94
07:48 PM roycroft: my first rpn calculater was a 31e
07:48 PM roycroft: and i've never gone back since then
07:48 PM roycroft: it's been all hp for me
07:48 PM zephyr9900: I love the HP calculators. I have an HP28 emulator on my phone
07:48 PM roycroft: the 31e is long gone
07:48 PM roycroft: my oldest current hp is an 11c
07:49 PM roycroft: which has my favorite footprint of any hp calculators
07:49 PM roycroft: i have one on my desk right now
07:49 PM zephyr9900: I mean HP 48 not 28
07:49 PM roycroft: i have several hp48s in my shop :)
07:50 PM zephyr9900: The HP 48 was my favorite but the real one died one day.
07:50 PM roycroft: one by my woodworking bench, one in a drawer by my mill, one in a drawer by my lathe
07:50 PM roycroft: and i have a 32sii in my backpack that travels with me everywhere
07:50 PM roycroft: that's another of my favorite all-time hp calculators
07:51 PM roycroft: https://www.ebay.com/itm/175416099457
07:52 PM roycroft: the old, original ones with the red displays are nostalgic, but i really never liked the form factor
07:53 PM roycroft: it's the horizontal ones like the 11c, and the 16c, which i never owned but still lust after, that i really liked
07:54 PM zephyr9900: In college I wore it on my belt
07:54 PM roycroft: there's a 16c on ebay right now going for $250, which is actually tempting
07:54 PM roycroft: it claims to be a new, open box item, and it does look mint
07:55 PM zephyr9900: Also National Semiconductors made an RPN calculator for a while my Dad had one.
08:02 PM roycroft: i don't know how people tolerate non-rpn calculators :)
08:03 PM roycroft: but then again, i don't now how people tolerate programming in lisp
08:03 PM zephyr9900: LOL
08:04 PM roycroft: both, i think, are the result of conspiracies by the manufacturers of ( and ) keys to promote the excessive use of those keys
09:15 PM Centurion_Dan1 is now known as Centurion_Dan
09:34 PM JoseIgnacioRomer: yay i finished wiring up my mill
09:35 PM JoseIgnacioRomer: getting tons of noise on the inputs though :(
09:36 PM Tom_L: need better shielding
09:38 PM * skunkworks[m] uploaded an image: (466KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/UOFuyfTEhGpNUgzcuhFwqslF/PXL_20230116_030815857.jpg >
09:39 PM skunkworks[m]: Might be liking freecad...
09:39 PM Tom_L: what is that/
09:39 PM XXCoder: designed in freecad eh
09:39 PM Tom_L: ?
09:39 PM JoseIgnacioRomer: unfortunately that would require me to redo the wiring, which i dont wanna
09:40 PM Tom_L: well if it's a problem, you may not get a choice
09:40 PM Tom_L: star grounds on everything
09:40 PM Tom_L: keep signal wires away from power ones
09:40 PM Tom_L: shield signal wires
09:40 PM Tom_L: i grounded the motor frames on mine as well
09:41 PM skunkworks[m]: Tom_L: some pwm amps that I am driving from the printer port..
09:41 PM Tom_L: looks like you got your thumb in the way of something sharp
09:42 PM JoseIgnacioRomer: yeah i didn't do the wiring, it has the signal and motor wires in the same harnesses, somehow it worked fine with the original controller
09:42 PM Tom_L: luck
09:42 PM JoseIgnacioRomer: i'll throw in some measurements to see what the noise actually is
09:42 PM skunkworks[m]: Jambed a philips bit into my thumb.. Been using my daughters nail paint to keep it together..
09:43 PM Tom_L: heh
09:43 PM Tom_L: and ouch
09:43 PM skunkworks[m]: LOL - *finger nail polish..
09:43 PM JoseIgnacioRomer: best guess of course is that it is the stepper drivers
09:43 PM XXCoder: now thats usercase for one that I never heard of
09:43 PM XXCoder: power and stepper is quite high noise yeah
09:44 PM JoseIgnacioRomer: it may actually not be a real problem, i havent seen what linuxcnc sees on those inputs, only that the leds on the mesa card get partially on
09:44 PM JoseIgnacioRomer: aesthetic problem perhaps, but maybe some filtering can get rid of it
09:53 PM JoseIgnacioRomer: lol, this thing is putting out 20vpp at 20KHz
09:54 PM JoseIgnacioRomer: just putting 100nF to ground squelches it down to less than a volt
09:55 PM JoseIgnacioRomer: how much current is this mesa card running through the inputs
09:56 PM JoseIgnacioRomer: apparently 5mA
