#linuxcnc Calendar

01:28 AM t4nk_fn: oioioi, _unreal_, return of the prodigy :)
01:53 AM -!- #linuxcnc mode set to +v by ChanServ
02:01 AM sensille: CaptHindsight[m]: thanks again for your hints, works well :)
02:01 AM sensille: and now i can smb mount the server again
02:28 AM Deejay: moin
03:27 AM pere: morning. :)
03:33 AM pere: how come the chapter in the linuxcnc documentation on pid tuning, <URL: http://linuxcnc.org/docs/html/motion/pid-theory.html >, do not mention ff1 like <URL: https://wiki.linuxcnc.org/cgi-bin/wiki.pl?Tuning_LinuxCNC/HAL_PID_Loops > do.
03:42 AM pere: I created <URL: https://github.com/LinuxCNC/linuxcnc/issues/2116 > to track this, in the hope that someone who understand pid tuning find time to write something in the documentation.
04:14 AM pere: Is there a problem with the solution in <URL: https://github.com/LinuxCNC/linuxcnc/pull/2054 >?
04:45 AM JT-Cave: morning
04:46 AM travis_farmer[m]: G'Morning
05:34 AM Tom_L: morning
05:56 AM Tom_L: pere, when that wiki was written (last update 2012) possibly PID didn't have FF1 2.5 docs don't show it
05:56 AM Tom_L: http://linuxcnc.org/docs/2.5/html/motion/pid_theory.html
05:56 AM Tom_L: which would be near that era
05:57 AM Tom_L: JT-Cave, did you stop using filelist.hal?
06:02 AM JT-Cave: yes
06:11 AM pere: Tom_L: aha. perhaps you know enough to move some text over?
06:11 AM pere: I managed to get the axis moving with autotuning, but both z and y is shaking quite a lot.
09:00 AM Tom_L: pere, just need the 'password' for the wiki
09:00 AM Tom_L: it's the linuxcnc mascot
09:02 AM Tom_L: JT-Cave, that original ini had filelist.hal and i'd removed it for some reason so it broke the config until i added the hal back
09:02 AM Tom_L: tested sserial last night..
09:04 AM Tom_L: pere, P is too high on your servos
09:04 AM JT-Cave: did you have more than one hal file?
09:04 AM Tom_L: back off a bit and add some D or I
09:04 AM Tom_L: on the original i did
09:04 AM Tom_L: i'd tried several things. io, sserial etc
09:05 AM JT-Cave: mesact should preserve all the key-values in [HAL]
09:05 AM Tom_L: it was my doing
09:05 AM JT-Cave: oh ok
09:05 AM Tom_L: and it was probably prior to the filelist.hal fix
09:06 AM Tom_L: i wanted to be sure not only building configs but putting them to hardware also works
09:14 AM Tom_L: pere, https://wiki.linuxcnc.org/cgi-bin/wiki.pl?BasicSteps
09:56 AM roguish[m]: Tom_L: you gonna work on the wiki ??? that's good.
10:07 AM Tom_L: roguish[m], i think that's pere's thing
10:07 AM roguish[m]: I added a little to it a lot of years ago
10:08 AM Tom_L: he wants to add FFx to it
10:08 AM roguish[m]: waz that?
10:08 AM Tom_L: i don't think that was much of a thing back when it was written
10:09 AM Tom_L: https://wiki.linuxcnc.org/cgi-bin/wiki.pl?Tuning_LinuxCNC/HAL_PID_Loops
10:09 AM Tom_L: updated 2012
10:09 AM roguish[m]: yeah. i've used that page...
10:10 AM roguish[m]: well, cool and foggy here. and we are actually supposed to get some rain this next week....
10:11 AM Tom_L: too dry for fog here
10:11 AM Tom_L: cloudy though
10:15 AM sensille: Loetmichel_: did you ever think about adding a tool changer to the 6040? are there any cheap options?
10:19 AM JT-Cave: Tom_L, if the ini version is behind the mesact version a backup copy is saved before opening the ini now
10:24 AM Tom_L: backup of the config?
10:24 AM Tom_L: i haven't seen any problems updating yet. just that one and i did that myself
10:26 AM JT-Cave: yes, it makes a backup copy of the config and puts it in a zip file
10:26 AM Tom_L: i say if you haven't backed up your config yourself you deserve what you get :)
10:26 AM JT-Cave: they may be NewNotKnowHow
10:26 AM Tom_L: likely so
10:27 AM Tom_L: roguish[m] was asking about testing the 7i80 but it's not working yet
10:27 AM JT-Cave: I also fixed addding in the readme file into the tool
10:28 AM Tom_L: what cards are actually available now?
10:28 AM JT-Cave: 7i96s
10:28 AM Tom_L: those would be the first targets to finish
10:28 AM JT-Cave: yup
10:29 AM JT-Cave: I do have a 7i80HD-16
10:29 AM Tom_L: i know but you can't do much with it yet
10:29 AM JT-Cave: and maybe a daughter card or two
10:29 AM Tom_L: i tried last night
10:30 AM JT-Cave: only some firmware will allow you to pick a daughter card
10:31 AM Tom_L: maybe show the firmware for the available daughter cards but keep the others to add later
10:32 AM JT-Cave: hmm that's not working for some reason yet unknown to me
10:32 AM Tom_L: i tried one of the 7i47s
10:34 AM JT-Cave: looks like it's an underscore vs a dash lol and neither one won
10:38 AM JT-Cave: I remember what it was now a function name can't have a - but the boardCB data has a -
10:38 AM Tom_L: i recall you had a similar problem with those
10:45 AM JT-Cave: I just removed all dashes and underscores from the 7i80 boards
10:46 AM JT-Cave: I think I need to have a checkbox to show all firmware or maybe a radio button for all or supported
10:49 AM Tom_L: something to simplify selections
10:50 AM pere: Tom_L roguish[m]: actually, I hope someone can update the PID tuning chapter in the official documentation, the one that is translated to other languages, for maximum availability. :)
10:50 AM Tom_L: i could probably delet the ini3 ini4 branches from my repo now you think?
10:51 AM pere: roguish[m]: btw, I am still waiting for your feedback on the div2 component.
10:51 AM Tom_L: pere, i'm not that well versed in PID
10:51 AM * pere neiter, but I need to learn from the best to get the Mazak tuned. :)
10:52 AM Tom_L: i'm sure the FF components would come into play but most PID i've done is just PID
10:52 AM JT-Cave: the 7i80 somewhat works now I think
10:53 AM Tom_L: ok
10:53 AM Tom_L: roguish[m], ^^
10:54 AM pcw-home: For position feedback, velocity command loops, FF1 is critical
10:55 AM pcw-home: for velocity feedback, velocity command (like a spindle) FF0 is critical
10:56 AM JoseIgnacioRomer: hi guys, best place to buy mesa cards in the US is mesaus.com right?
10:57 AM Tom_L: that or mesanet.com
10:57 AM Tom_L: they both camp out here
10:59 AM JoseIgnacioRomer: looks like pretty much there is just a handful of 7i96s cards for a setup like mine (basic 3 axis mill)
11:00 AM JoseIgnacioRomer: machine is 3 stepper axes and a 0-10v spindle. i want to add probing and toolsetter
11:04 AM pcw-home: A 7I96S should do for that if it has enough inputs (it has 11 total)
11:06 AM Tom_L: do you have db25 daughtercards in stock for it?
11:06 AM Tom_L: for extra io
11:08 AM pcw-home: For more I/O you would likely use something like a 7I84 (connected to the 7I96S serial expansion))
11:09 AM pcw-home: most DB25 expansion cards are for things like more step/dir, encoders, or SSerial
11:09 AM Tom_L: faster needs
11:09 AM pcw-home: yeah
11:11 AM JT-Shop: actually it's store.mesanet.com/
11:11 AM JoseIgnacioRomer: yay i just grabbed one. my machine only needs 3 inputs stock (all the limits into one, safety door and drawbar position)
11:12 AM JoseIgnacioRomer: went with mesaus because the stock has a smiling face
11:12 AM Tom_L: haha
11:12 AM JT-Shop: JoseIgnacioRomer, thanks
11:13 AM JoseIgnacioRomer: i appreciate that despite the low stock people arent gouging on these things...
11:14 AM JT-Shop: JoseIgnacioRomer, I have a configuration tool for mesa cards
11:14 AM JT-Shop: https://gnipsel.com/linuxcnc/mesact/index.html
11:14 AM JoseIgnacioRomer: wiring this should be super easy compared to the cheapskate way i wanted to go before making my own breakout to plug on the IDC of the cheaper cards
11:18 AM JoseIgnacioRomer: im thinking of buying one of those touchscreen "all in one" pcs to do linuxcnc, since it doesnt need to be as timing sensitive with the Ethernet cards
11:24 AM Tom_L: JT-Shop, the 7i47s bit files would likely not work on the 7i47
11:24 AM Tom_L: slight pinout difference for the analog spindle
11:25 AM Tom_L: afk
11:39 AM JT-Cave: ok
11:39 AM JT-Cave: which firmware was that on?
11:47 AM JT-Cave: I'll read back... nap time
12:03 PM Tom_L: JT-Cave, anything with an s on the end
12:04 PM Tom_L: 7i47s
12:05 PM * Tom_L 2nds the nap
12:29 PM JT-Cave: did you see somewhere in mesact that a 7i47s firmware allowed a 7i47 card?
12:29 PM Tom_L: phone..
12:34 PM Tom_L: the dropdown for the daugher card is only for 7i47 iirc
12:35 PM perry_j1987: mornin
12:38 PM Tom_L: ok i think part of what is happening is once you select a firmware the daughter cards appear in the dropdown but if you select a different one, the same cards are still in the dropdown
12:41 PM Tom_L: i don't know what cards associate with each firmware so it's hard for me to tell if they are correct
12:43 PM JT-Cave: ah ok, the cards need to be blanked if not in the dictionary
12:44 PM Tom_L: for the 7i80hd_16_st12.bit i get 7i47 & 7i47 for each daughter card. when i select 7i80_16_svst1_4_7i47s.bit the cards remain the same in the dropdown
12:44 PM Tom_L: or blanked if you choose a different bit file
12:45 PM Tom_L: i think it would become quite a puzzle to figure every card that would work with any given firmware
12:46 PM Tom_L: maybe some sort of lookup table...
12:46 PM Tom_L: no idea
12:47 PM Tom_L: and
12:48 PM Tom_L: i'm not sure if the 's' is sserial or spindle (analog out)
12:48 PM Tom_L: i know the 7i47s is spindle since i have one
12:51 PM Tom_L: for example the 7i80hd_16_svst6_6_7i52s.bit
12:53 PM JT-Shop: yeah I just blanked the daughter cards if not in the card dictionary... really don't understand the 7i80 that much
12:53 PM Tom_L: an awful lot of bitfiles to understand for sure
12:55 PM Tom_L: on the 7i52s i would think it to show pwmgen but i don't see that or sserial
12:57 PM Tom_L: the 7i96s is fairly straighforward
12:57 PM JoseIgnacioRomer: is there any reason one would want to use 2.9 over the latest 2.8?
12:58 PM Tom_L: newer is always better isn't it?
12:58 PM Tom_L: 2.8.4 was just released
12:58 PM JoseIgnacioRomer: `press X to doubt`
12:59 PM Tom_L: you may need 2.9 for the 7i96s i honestly can't remember
12:59 PM Tom_L: been going back and forth on things here too much
12:59 PM JoseIgnacioRomer: apparently that was the whole reason for 2.8.4 to come out
12:59 PM JoseIgnacioRomer: anything else new? i saw 2.9 has some new lathe cycles which are irrelevant to my mill
12:59 PM Tom_L: it did fix a problem with that yes
01:00 PM Tom_L: and afik, if you need a different firmware downloaded you still have to build mesaflash from source since it requires ver 3.4.3
01:01 PM Tom_L: and they haven't released a deb for it yet
01:01 PM Tom_L: or added to 2.9... however the process is done
01:02 PM Tom_L: very simple to build though
01:04 PM JoseIgnacioRomer: in any case the linuxcnc controller will be a huge upgrade to this machine
01:04 PM JoseIgnacioRomer: the current one runs windows 98 lol
01:04 PM Tom_L: JT-Cave, i might suggest not associating the 7i80 bit files with any particular card. the bitfile descriptions are there to read
01:05 PM Tom_L: allow to download them but let the user decide which one fits his needs
01:06 PM JoseIgnacioRomer: it uses a custom ISA card to generate the steps, but the control software sucks, it lacks lookahead and it seems to do arcs in software, in the worst way possible
01:06 PM Tom_L: the 5i25? & friends are a bit more restricted on daughter cards i think
01:06 PM Tom_L: either a servo card or stepper card basically...
01:06 PM JoseIgnacioRomer: machine comes to a halt for a split second before every arc
01:07 PM Tom_L: leaving a divid behind?
01:07 PM Tom_L: divit
01:07 PM Tom_L: the old boss5 were programmed in quadrants and you could see every 1/4 circle
01:08 PM JoseIgnacioRomer: yep, looks like it waits for the move queue to flush, leisurely calculate the segments for the arc and put them in after the machine had been stopped for almost a second
01:08 PM JoseIgnacioRomer: i modified my postprocessor to make the arcs into segments and i get better performance, lol
01:09 PM JoseIgnacioRomer: still no lookahead so short segments bog down the machine
01:09 PM Tom_L: so now you get polygons
01:09 PM JoseIgnacioRomer: yep, instead of chattermarks + polygons
01:10 PM Tom_L: or 10k lines for an arc
01:10 PM JoseIgnacioRomer: yeah it is ridiculous though, the machine has a whole pentium 3 processor on it
01:10 PM Tom_L: my bud had a commercial cnc with windows..
01:10 PM Tom_L: he didn't keep it very long
01:10 PM JoseIgnacioRomer: it can even do volumetric gcode simulation at faster than realtime
01:11 PM JoseIgnacioRomer: but once motion controlling? they got the intern to write the algorithms
01:13 PM JoseIgnacioRomer: im replacing it wholesale because the original stepper drivers are L298 (lol)
01:14 PM Tom_L: popular bottom end driver
01:14 PM JT-Shop22: JoseIgnacioRomer, only use 2.9 if you need a feature that is not in 2.8.4
01:15 PM * Tom_L goes for that long awaited nap
01:15 PM JT-Shop22: 2.8.4 works with the 7i96s
01:16 PM Tom_L: i couldn't remember what the fix was for
01:17 PM JoseIgnacioRomer: Tom_L: to be fair, it was made in the 90s
01:17 PM JT-Shop22: JoseIgnacioRomer, https://gnipsel.com/linuxcnc/index.html
01:18 PM JT-Shop22 is now known as JT-Shop2
01:19 PM JT-Shop2: debian 10 is a good choice, for debian 11 you want 5.10 kernel
01:20 PM * JT-Shop2 goes back to cleaning the differential
01:21 PM JoseIgnacioRomer: nice, i think i may go with debian 11 since all my other computers run that
01:23 PM CaptHindsight[m]: you can run a 3.x to a 6.x kernel on a wide range of Debian versions
01:26 PM CaptHindsight[m]: it's just easier for people that aren't able to mix and match Debian versions and kernel versions to use a Debian version with the kernel that is available in the package manager you hope will work well
01:29 PM JoseIgnacioRomer: hmmm yeah i think i may just go 2.9 since it goes on debian 11, kinda dont feel like bringing up a brand new debian 10 system in late 2022
01:31 PM CaptHindsight[m]: Debian has a LCNC package for 12 (Bookworm)
01:31 PM Tom_L: i've been testing on 12 and so far so good
01:32 PM Tom_L: but it's not a full release yet
01:32 PM CaptHindsight[m]: 12 and Sid have issues with AMD graphics/cpus, it can take minutes from login to desktop at times
01:33 PM JoseIgnacioRomer: is bookworm freeze nezt feb?
01:34 PM JoseIgnacioRomer: next march
01:34 PM JoseIgnacioRomer: i wonder if 2.9 will come out before then
01:35 PM CaptHindsight[m]: versions of 2.9 have been out for over a year :)
01:36 PM CaptHindsight[m]: all depends on what you find that works and broken for you
01:36 PM CaptHindsight[m]: and if you want to compile things yourself vs just wait for packages
01:49 PM JoseIgnacioRomer: not released though, the debian package is pulling from git without a tag
02:01 PM JT-Shop2: JoseIgnacioRomer, you will want to read this thread before selecting a kernel https://forum.linuxcnc.org/27-driver-boards/46911-mesa-hm2-hm2-7i96s-0-error-finishing-read
02:07 PM CaptHindsight[m]: "You can actually grab the sid 6.0 kernel and drop it on Bullseye and perhaps even Buster"
02:08 PM CaptHindsight[m]: "The problem you may run into though is that the X.org driver stack may not be new enough. libdrm, mesa and xserver-xorg-video-intel... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/7486526fcbf5e747105f2279af3efafb821acc1a>)
02:10 PM CaptHindsight[m]: We have a 4.19rt running on Bookworm
02:11 PM CaptHindsight[m]: there was only a complaint about some missing systemD crap that you really don't want working anyway
02:12 PM CaptHindsight[m]: JT-Shop2: it's frustrating to read that thread on the forums
02:13 PM CaptHindsight[m]: first time that I have seen it, there is so much confusion about kernels that can be cleared up
02:18 PM CaptHindsight[m]: the title for that thread is why I didn't even look at it
02:18 PM CaptHindsight[m]: it's actually about kernels!
02:19 PM JoseIgnacioRomer: Hmmm
02:19 PM JoseIgnacioRomer: Well the machine im getting is an intel SoC, i saw it needs an irq tweak
02:20 PM CaptHindsight[m]: Jose Ignacio Romero: which post?
02:21 PM JoseIgnacioRomer: https://gnipsel.com/linuxcnc/debian-11-eth.html
02:23 PM CaptHindsight[m]: Jose Ignacio Romero: yeah that is known Intel Nic issue with Mesa, but it dosen't matter which kernel, it will happen for all
02:24 PM JT-Shop2: well when I started the thread I didn't know it was going to be about kernels...
02:24 PM CaptHindsight[m]: :) of course
02:25 PM CaptHindsight[m]: and the horrible editor for forum posts
02:25 PM JoseIgnacioRomer: Its all about the kernels
02:26 PM JoseIgnacioRomer: Lets see if this roll of the dice pays off, i got a crappy aio pc with touch for $100 on ebay
02:26 PM JT-Shop2: I should check to see if the forum software has any updates
02:27 PM xxcodery: jose "it's always have been"
02:27 PM CaptHindsight[m]: fire lathes https://www.youtube.com/watch?v=m-9WCxThO7Q
02:29 PM CaptHindsight[m]: Debian does some wired stuff with kernels and X, it always has problems where we don't with just building properly on Gentoo
02:32 PM CaptHindsight[m]: it's due to tradeoffs between trying to support everything for everyone and supporting only what you have and need
02:34 PM xxcodery: CaptHindsight[m] nice video
02:34 PM xxcodery: I finally oatially solved video problem yeserdaym, videos is now mostly watchable lol
02:35 PM CaptHindsight[m]: xxcodery: really more of just a big turret with multiple spindles, but with FIRE!
02:35 PM xxcodery: yep lol
02:36 PM CaptHindsight[m]: my machine makes one of those glass pipes every 3 seconds
02:39 PM JoseIgnacioRomer: Of course, its a glasverformungsmaschine
02:40 PM xxcodery: capt I guess yours automates out that guy inserting tubes?
02:46 PM CaptHindsight[m]: xxcodery: yes and uses faster ways of forming, plus I also perform a fusing operation at the same time
02:46 PM CaptHindsight[m]: you still have to QC by eye
02:46 PM CaptHindsight[m]: but you can do that later after the glass has cooled in a bin
02:47 PM CaptHindsight[m]: all using LCNC
02:47 PM xxcodery: nice
02:48 PM CaptHindsight[m]: xxcodery: hey did that SLS project announce anything as far as design files yet?
02:48 PM xxcodery: been quiet mostly
02:49 PM xxcodery: after week or so they finally had discussion about heating elements. quiet again now
02:53 PM CaptHindsight[m]: i can't even look at his kludge of reprap control boards
02:53 PM CaptHindsight[m]: he could have it programmed in a day with LCNC
02:54 PM xxcodery: yeah
02:54 PM xxcodery: every hw you suggest he glosses over
02:54 PM CaptHindsight[m]: once again LCNC gets poo pooed for unknown reasons
02:54 PM CaptHindsight[m]: that is why i don't trust him
02:55 PM CaptHindsight[m]: he has his own agenda vs open
02:55 PM CaptHindsight[m]: I'm sure it will be open eventually
02:55 PM xxcodery: possible its due to sponsorship. lcnc part dunno
02:55 PM CaptHindsight[m]: yeah there is something going on
02:56 PM xxcodery: too bad really. would love to have cheap-ish sls
02:56 PM xxcodery: but sls of only black nylon meh
02:57 PM CaptHindsight[m]: I'd look at multijet fusion or binderjet version of it
02:57 PM CaptHindsight[m]: will be faster and better
02:57 PM CaptHindsight[m]: and in full color
02:58 PM CaptHindsight[m]: I wish i had more time
02:58 PM CaptHindsight[m]: I'd put 3d models up for people to start their own versions
02:58 PM xxcodery: maybe once you retire
02:59 PM xxcodery: or jt style of retirement anyway
02:59 PM JT-Shop2: lol
02:59 PM CaptHindsight[m]: https://github.com/gkyle/xaar128
03:00 PM xxcodery: so, basically vaporize vinyl and depost it
03:01 PM CaptHindsight[m]: slow heads but relatively cheap <$300
03:01 PM xxcodery: but dont vinyl have cyanode in it
03:01 PM CaptHindsight[m]: ah nope, use whatever in powder form, spread a layer, then inkjet scans over
03:02 PM CaptHindsight[m]: cure the inkjet fluid, repeat
03:03 PM CaptHindsight[m]: multijet fusion goes one step further with heting each layer causing the binder and powder to fuse
03:03 PM CaptHindsight[m]: s/heting/heating/
03:03 PM xxcodery: ahh ok
03:04 PM CaptHindsight[m]: you can even print metals this way
03:04 PM CaptHindsight[m]: you would just sinter after in an oven
03:04 PM xxcodery: what about warping?
03:04 PM CaptHindsight[m]: printed black nylon is only so useful
03:05 PM xxcodery: yep
03:05 PM CaptHindsight[m]: xxcodery: that comes down to limitations of the shapes, metals, etc and how it is sintered
03:07 PM CaptHindsight[m]: consider a diy for a few $k's vs >> $100K's for a off the shelf machine
03:08 PM CaptHindsight[m]: for the price of parts for a small CNC lathe or mill you can make a powder bed printer
03:14 PM * CaptHindsight[m] uploaded an image: (183KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/APdTdufzvZMmoPTLpDEOXxfr/Wiring_diagram_v01.png >
03:16 PM * CaptHindsight[m] uploaded an image: (118KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/vDIWNOVmIwdyYxEhUiOSsFnY/20220225_150041.jpg >
03:16 PM xxcodery: 4 boards
03:16 PM xxcodery: one rpi, one skr
03:16 PM xxcodery: and 2 drivers board
03:17 PM CaptHindsight[m]: is he really using nema17 for motors?
03:17 PM xxcodery: 8 boards, some of em not sure what it is. like 2 on laser module side
03:17 PM xxcodery: looks like
03:17 PM CaptHindsight[m]: its like "what can i build form my reprap parts only"
03:17 PM CaptHindsight[m]: oh well
03:18 PM xxcodery: yeah
03:18 PM CaptHindsight[m]: I thinks lots of people only know those parts from their CNC glue gun building days
03:19 PM CaptHindsight[m]: so they get applied everywhere
03:19 PM xxcodery: everything looks like nails to guy with hammer
03:19 PM CaptHindsight[m]: yeah
03:19 PM Loetmichel_: sensille: no cheap options i know of. the cheapest tool changer spindle i know is nearly 1000 eur.
03:20 PM CaptHindsight[m]: Loetmichel_: so what you are saying is that someone needs to give the Chinese a cheap tool changer design to copy
03:20 PM Loetmichel_: basically yes
03:20 PM Loetmichel_ is now known as Loetmichel
03:21 PM sensille: Loetmichel: cheapest i could find: https://shop.stepcraft-systems.com/Automatischer-Werkzeugwechsler-fuer-AMB-1400-FME-P-DI
03:21 PM sensille: they have 3 different ones
03:22 PM sensille: but i have no idea if and how they would fit
03:23 PM Loetmichel: problem with that is that its made for a router motor, not for a 3 phase spindle
03:23 PM ZincBoy[CAON][m]: That is just the changer head though, still need the spindle. It is really hard to make a cheap tool changer spindle because of the high precision parts that are mandatory for it to be useful
03:23 PM CaptHindsight[m]: who makes the lowest cost drawbar spindle?
03:24 PM ZincBoy[CAON][m]: You can pick up a bt30 drawbar spindle on aliexpress for a few hundred.
03:24 PM xxcodery: I remember reading about small toolchanger that isnt too expensive
03:24 PM xxcodery: but been a while
03:25 PM ZincBoy[CAON][m]: All the ones I am aware of had issues with runout and/or rigidity.
03:25 PM CaptHindsight[m]: https://tormach.com/bt30-power-drawbar-kit-50433.html
03:25 PM CaptHindsight[m]: https://www.aliexpress.com/i/4000026637895.html
03:26 PM xxcodery: 1k ouch lol
03:26 PM ZincBoy[CAON][m]: The tormach system is the best way to retrofit a tool changer onto a R8 or bt30 spindle.
03:26 PM perry_j1987: 0.545 mm is what i have set as the thread depth for this m10x1 thread here on the lathe but its too tight still
03:26 PM CaptHindsight[m]: the ali one is under $600
03:26 PM xxcodery: I rather use myself as "toolchanger" though still want some tiny collet like cat10 rather than just tighten nut and measure tool
03:26 PM sensille: and also the ones from stepcraft need 9 bar to operate
03:26 PM ZincBoy[CAON][m]: That kit is pretty much exactly what I put together for the NM145 mill I had.
03:26 PM perry_j1987: thought in fusion a 1mm pitch thread should be keyed in as half so .5
03:27 PM perry_j1987: so im up to .545 and still too tight what am I doing wrong lol
03:27 PM CaptHindsight[m]: buy the chinaco spindle, swap bearings, enjoy
03:27 PM CaptHindsight[m]: plus maybe a regrind
03:27 PM xxcodery: definitiely would check runout and stuff
03:27 PM sensille: + 200 euro shipping
03:28 PM ZincBoy[CAON][m]: I used an air over hydraulic unit for the plunger though so I could just use 6 bar air.
03:28 PM JT-Shop: pcw-home, did you say the 7i92 is the next board to get the new fpga chip?
03:28 PM CaptHindsight[m]: https://m.aliexpress.com/item/1005001988763424.html
03:28 PM Tom_L: that would make sense... small board that will suit most needs
03:29 PM CaptHindsight[m]: ha youfuly vs youfooly
03:30 PM sensille: 3 euro store discount!
03:32 PM CaptHindsight[m]: ask the Chinese to copy the Tormach :)
03:32 PM CaptHindsight[m]: $500 and lasts 1/4th as long
03:32 PM JT-Shop: hmm my bronze shift fork pads will be here Monday and I can start putting it back together
03:33 PM Tom_L: maybe you should measure and cad them up
03:33 PM CaptHindsight[m]: LPT BOB's are $30-40 for decent one
03:34 PM CaptHindsight[m]: not to hard to decide between $30 for a PCIe LPT card + $30 BOB
03:34 PM CaptHindsight[m]: and 7i92
03:37 PM * JT-Shop needs to clean off his desk
03:37 PM CaptHindsight[m]: new RTAI debs are available
03:38 PM CaptHindsight[m]: should appear on the mail list in a few minutes
03:38 PM Tom_L: what kernel version?
03:38 PM xxcodery: jt I bet thats true for everyone
03:38 PM CaptHindsight[m]: 4.19 debs
03:38 PM CaptHindsight[m]: after testing he'll push 5.4
03:39 PM CaptHindsight[m]: so test away, please
03:39 PM Tom_L: work on bookworm?
03:39 PM CaptHindsight[m]: https://github.com/NTULINUX/RTAI/releases/tag/v5.3.3-beta
03:40 PM CaptHindsight[m]: Tom_L: yes, developed using Bullseye
03:40 PM CaptHindsight[m]: should work from Buster through Bookworm
03:40 PM CaptHindsight[m]: "emoved ACPI power states, this should improve performance but may require holding power button down after the system is halted as software shutdown may not work properly. Is this a problem for anyone and is software shutdown required?"
03:45 PM CaptHindsight[m]: https://sourceforge.net/p/emc/mailman/message/37728174/
03:56 PM codebuster2796[m: where the hell can a guy get a Mesa board anymore? /:
03:58 PM codebuster2796[m: the fpgapocalypse is tangible
04:00 PM JT-Shop: you can get 7i96S from me and some smart serial boards
04:01 PM roguish[m]: JT-Shop: hey, pere just helped me do a pull request for a comp....
04:01 PM * JT-Shop wonders if he should replace the O2 sensors while he can?
04:01 PM JT-Shop: cool
04:02 PM xxcodery: if its huge work to get that far then yes
04:02 PM xxcodery: well if o2 sensor is old anyway
04:02 PM pere: roguish[m]: was it hard?
04:03 PM JT-Shop: I get an occasional check engine light on one of the 4 O2 sensors
04:05 PM roguish[m]: pere: not difficult, just new to the amateur
04:37 PM JT-Shop: finally found some oem O2 sensors
04:39 PM JT-Shop: roguish[m], you have more work to do...
04:42 PM pcw-home: JT-Shop, Yes the 7I92TF,TM,TH are coming soon (protos work, production kitting almost finished)
04:44 PM JT-Shop: TF female db25, TM male db25 and TF?
04:44 PM Tom_L: idc header probably
04:44 PM JT-Shop: if you have a spare proto I'd like to test it with mesact
04:45 PM JT-Shop: TH idc yes that makes sense
04:45 PM Tom_L: building to see what you did
04:46 PM JT-Shop: just some minor stuff for 7i80 so they don't have errors
04:46 PM Tom_L: i've got an old version 7i92 as well
04:47 PM JT-Shop: I have one somewhere lol
04:47 PM Tom_L: may be fun to keep track of bit and bin files
04:47 PM JT-Shop: I know where the bag is...
04:47 PM JT-Shop: it's easy in mesact
04:47 PM JT-Shop: each board has it's own directory for firmware
04:48 PM Tom_L: gotta be careful which deb i pick since i have 3 to select
04:48 PM JT-Shop: lol
04:49 PM Tom_L: once you clear them the rest show no daughter cards in the pull down
04:50 PM Tom_L: i just picked a couple at random...
04:51 PM JT-Shop: yeah I should have done that a long time ago... until someone notices something I may not know to fix it :)
04:51 PM pere: roguish[m]: you got quick feedback from someone who know the linuxcnc code. :)
04:52 PM JT-Shop: knows C
04:53 PM Tom_L: found a couple that show different cards
04:53 PM pcw-home: JT-Shop yeah I have a spare proto
04:54 PM pcw-home: (should work as is as a 7I92 except for bitfiles)
04:54 PM JT-Shop: ok
04:54 PM Tom_L: has mesaflash 3.4.3 been pushed to master yet?
04:55 PM pcw-home: (LinuxCNCs driver truncates the name to 4 chars so it thinks its a 7I92)
04:55 PM Tom_L: i saw someone mention it a few days ago
04:55 PM JT-Shop: see if you can get the boss to send it to me :) if she's not too busy with art projects
04:55 PM pcw-home: Art,crochet and beads...
04:55 PM JT-Shop: LOL
04:56 PM JT-Shop: and peace signs
04:56 PM pcw-home: Yeah we can send you one
04:56 PM Tom_L: once you did the first firmware have the rest been a little easier to convert?
04:56 PM JT-Shop: thanks
04:57 PM pcw-home: Yes, porting is basically done (only the top level files =TopXXX.vhd and hostmot2.vhd change)
04:59 PM pcw-home: Even those would not have to have been changed except for the Efinix tools weird way of dealing with tri-state pins
04:59 PM Tom_L: JT-Shop, if you select a bit file then move that back to 'Select' it still retains the daughter cards that were visible
05:00 PM JT-Shop: ok, I'll fix that in the morning... I "think" I know exactly why
05:00 PM pcw-home: I think you need mesaflash 3.4.6 for the 92tX
05:00 PM Tom_L: different than the 7i96s?
05:00 PM pcw-home: newer
05:01 PM Tom_L: is it on git?
05:01 PM pcw-home: yest
05:01 PM pcw-home: yesh
05:01 PM pcw-home: yeast
05:01 PM Tom_L: yep
05:01 PM JT-Shop: ok good to know
05:03 PM Tom_L: building
05:03 PM Tom_L: updated
05:05 PM Tom_L: let's see if mesact knows
05:05 PM Tom_L: :)
05:05 PM Tom_L: yup
05:08 PM JT-Shop: knows what version of mesaflash?
05:09 PM JT-Shop: looks like 3.4.5 supports the 7i92T
05:10 PM JT-Shop: pcw-home, what is HM2_GTAG_ONESHOT?
05:10 PM CaptHindsight[m]: JT-Shop: is there an in stock combo of Step/Dir and 4-6 encoder inputs boards?
05:10 PM CaptHindsight[m]: pcw-home: ^^
05:11 PM JT-Shop: I forget what daughter card has encoders
05:11 PM pcw-home: Yes 7I96S + 7I89 or 7I85 or 7I85S
05:12 PM JT-Shop: 7i85 has 4
05:12 PM pcw-home: 7I89 is 8 encoders + 1 serial
05:12 PM JT-Shop: I have one of each :)
05:13 PM pcw-home: 7I85S is 4 encoders 4 step/dir +1 serial
05:13 PM CaptHindsight[m]: JT-Shop: 4 encoder channels 4 x A. B and index or?
05:13 PM pcw-home: 7I85 is 4 encoders and 5 serial
05:13 PM Total[m] is now known as Total0858[m]
05:14 PM pcw-home: yes encoder = A,B,Z single ended or diff
05:15 PM CaptHindsight[m]: thank you
05:15 PM CaptHindsight[m]: i always forget the part numbers
05:17 PM * JT-Shop goes to sit on the catio with the cats
05:17 PM pcw-home: JT-Shop: The oneshot module is a general purpose hardware oneshot
05:18 PM pcw-home: with hardware or software trigger and 2 timers and a rate generator
05:19 PM pcw-home: useful for pulse generation, delay generation, AC phase control, high resolution PWM etc
05:22 PM Tom_L: JT-Shop, yes
05:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/mesact/versions.png
05:28 PM pcw-home: I'm getting better at bumping the version number for each update
05:32 PM Tom_L: guess i missed .4 & .5
05:35 PM codebuster2796[m: jt-shop got a link to your shop?
05:38 PM Tom_L: https://mesaus.com/
05:39 PM codebuster2796[m: thanks
06:11 PM Tom_L: JT-Shop, 5i25_7i85s_7i78.bit only has 1 board association
06:12 PM Tom_L: the rest of those look good
06:13 PM Tom_L: same with 7i92_7i76_7i74D.bit
06:14 PM Tom_L: and 7i92_7i77_7i74D.bit
06:16 PM Tom_L: rest of those look ok except 7i92_7i76_7i85sdid.bit which may be an oddball anyway
06:17 PM Tom_L: 7i96_fallback.bit probably shouldn't be in the 7i96 list
06:20 PM Tom_L: when switching cards you may want to clear the ip address box
06:22 PM Tom_L: although all the ones i selected between _were_ ethernet so it may not matter so much
06:23 PM Tom_L: going from ethernet to pci does clear it so it's probably ok as iss
07:13 PM -!- #linuxcnc mode set to +v by ChanServ
07:22 PM CaptHindsight[m]: had someone offer to make an offer to buy a domain name we have had for over 25 years, the domain name is the same name as the company name
07:23 PM CaptHindsight[m]: they aren't Apple or Google by the way
07:25 PM xxcodery: "sure 10 billion dollars"
08:24 PM roycroft: i sold a domain name last year for high five figures
08:25 PM roycroft: it's one i'd had for almost 30 years
08:25 PM roycroft: the days of six figure and up domain name sales are pretty much over
08:25 PM roycroft: but the right domain could still command that kind of price
08:26 PM roycroft: iirc rio.com went for mid-six figures when it was sold a few years ago
08:41 PM CaptHindsight[m]: they are half way around the world away
08:42 PM CaptHindsight[m]: and many of the alternate .xxxare available,they just want the xxx.com
08:42 PM CaptHindsight[m]: and it's not even an exact match for their start up
08:48 PM CaptHindsight[m]: xxcodery: https://upload.wikimedia.org/wikipedia/en/thumb/1/16/Drevil_million_dollars.jpg/220px-Drevil_million_dollars.jpg
