01:12 AM Deejay: moin
03:14 AM travis_farmer[m]: G'Morning, really mourning the loss of my desktop motherboard... perhaps i will hold a funeral for it... ;-)
04:18 AM travis_farmer[m]: going to try the hard drive in my fathers old-ish (i3? i5?) desktop, see what it gets for latency. it still may run better than my old Dell Poweredge R200 LCNC production computer.
04:38 AM Tom_L: morning
04:48 AM JT-Cave: morning
08:17 AM JT-Shop: today's project clean off my desk and make folders for 2023 files
08:22 AM travis_farmer[m]: my projects include, the above listed old-ish computer test, and... ... i don't know, whatever else comes along... :-)
09:17 AM unterhausen: I wish I could get the cheap dells from salvage to have decent latency
09:22 AM roycroft: if you slingshot them around the sun you'll alter the space-time continuum, which will adjust the relative latency
09:23 AM unterhausen: the latency discussion on the forum is locked and points to an incredibly outdated wiki page
09:26 AM unterhausen: faq says to use a matrox video board. That's a name I haven't seen in a while
09:57 AM travis_farmer[m]: well, my fathers old-ish computer would not boot linux... so a rummaged around and found an intel I5 board. i will try it again and see if the latest tweaks get a usable latency number... i doubt it, but worth a try. i have to do the whole debian11 -> linuxcnc compile process all over again, as it would not boot the drive i used before. in fact, a re-install on it wouldn't even boot. so i think the boot sector of that drive got
09:57 AM travis_farmer[m]: toasted from the dead motherboard.
09:58 AM travis_farmer[m]: currently doing the install on my big 8TB drive, even though i don't need that much storage, but it is the only other drive i have.
10:01 AM unterhausen: too bad the smi control program hasn't been updated for 10 years
10:01 AM unterhausen: namespace pollution is going to render the intenet useless in a few years
10:07 AM unterhausen: everyone has their own "smi" even nvidia. They should know better
10:13 AM zephyr9900: smi ? system management interface?
10:24 AM * JT-Woodshop doesn't feel like working today
10:26 AM unterhausen: system management interrupt. On many poorly designed systems, it just goes out to lunch for up to 400ms periodically
10:27 AM unterhausen: can't be masked
10:27 AM unterhausen: often used to control fans, but mostly for ISA boards and diskette drives
10:29 AM zephyr9900: OK a source of bad latency in RT systems.
01:07 PM * travis_farmer[m] uploaded an image: (29KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/gFVgQTAMWFxvyPDLRDRBRAQa/travis-13Jan2023-2873.png >
01:08 PM travis_farmer[m]: doesn't look as scary as i thought...
01:08 PM travis_farmer[m]: strange, thought this was an I5, not an I3...
01:11 PM roguish[m]: it ain't just the i number. there's lots of factors in the latency.
01:12 PM travis_farmer[m]: i know, i was just suprized to see it was an I3
01:14 PM roguish[m]: i'm running on a J4105, simple quad core......
01:16 PM CaptHindsight[m]: unterhausen: those old forums on latency that mention trying an external graphics card apply to systems from 15 years ago and older
01:18 PM roguish[m]: simple on-board graphics is best. it's a machine controller, not a fraking video game box
01:18 PM unterhausen: Cap'n, I was just surprised the forum was that out of date
01:18 PM roguish[m]: shut down all the unnecessary shit. in bios and everywhere else...
01:19 PM unterhausen: some older systems had trouble with the on-board graphics, but maybe not any more
01:19 PM CaptHindsight[m]: unterhausen: yes, I still see mentioning old suggestions from time to time
01:19 PM unterhausen: you can't shut off smi
01:19 PM roguish[m]: ya do what ya can
01:20 PM unterhausen: I wonder if the smictrl utility can still work
01:21 PM CaptHindsight[m]: well we can't have open PC firmware since the BIOS EFI vendors need to make a living, plus that might give the average person more security
01:21 PM unterhausen: it's really a poorly written bios issue, I think
01:22 PM CaptHindsight[m]: many BIOSes are broken
01:22 PM unterhausen: I get the impression they spend about a day on a bios for a new system
01:23 PM CaptHindsight[m]: they just hope it works and fix it if enough customers complain
01:23 PM unterhausen: that seems right
01:24 PM CaptHindsight[m]: there is that long thread on the forums about the latency test script
01:25 PM CaptHindsight[m]: from there you can try to find a suitable CPU and motherboard combo
01:27 PM unterhausen: I prefer not to spend money
01:28 PM unterhausen: the systems I have work well except for smi, and are a good size
01:28 PM CaptHindsight[m]: namespace pollution has gotten pretty bad
01:28 PM unterhausen: actually, they might work with mesa ethernet cards
01:29 PM unterhausen: too bad you cant guarantee your timer interrupt is going to happen when an smi interrupt isn't going to happen
01:30 PM unterhausen: the problem with namespace pollution and google is that if you make a search, google wants to serve you those same results even though it gave you info about the wrong "smi"
01:32 PM CaptHindsight[m]: COST was a recent one, try to find out about that European program using Google
01:32 PM unterhausen: someone patented a way of hooking the smi interrupt
01:34 PM unterhausen: people that name something after a common English word should be slapped repeatedly about the head and shoulders with a large catfish
01:35 PM XXCoder: yeah new name should be only few results on google
01:35 PM XXCoder: I still remember next thing chip board
01:35 PM unterhausen: although once you told me it was a european program, finding "COST" was pretty simple
01:36 PM XXCoder: yes, company name is "next thing" and one board computer was named chip, or rather "c.h.i.p"
01:36 PM XXCoder: it was real tough name trying to find company and board then lol
01:36 PM unterhausen: I think the one that annoys me the most is the "go" language
01:36 PM XXCoder: probably why they went under
01:37 PM unterhausen: forced a batch of americans to learn to call it "baduk" or "wequi"
01:37 PM XXCoder: bad uk and we quit? ;)
01:38 PM CaptHindsight[m]: Monday is another holiday
01:39 PM JT-Woodshop: I wrote a program in go once
01:40 PM unterhausen: my adviser used to call anything too difficult to solve a "go game"
01:40 PM unterhausen: which I always thought was pretty funning since I played go a lot at the time
01:41 PM CaptHindsight[m]: I guess at Google GO has replaced Bash
01:41 PM unterhausen: they'll move onto something else eventually, but the namespace pollution will remain
01:44 PM CaptHindsight[m]: will be one big "who's on first"
02:30 PM travis_farmer[m]: well, i think the other computer i was working on a bit ago will work as a LCNC computer, even if not perfect. i will have to wait until i can run the machine with it, and run tort.ngc (the torture test) to see if it lets out the mysterious smoke ;-)
02:32 PM XXCoder: person who invented magic smoke injectors would be billionaire
02:33 PM travis_farmer[m]: lol
02:33 PM roycroft: i think the magic smoke is a failed experiment
02:33 PM roycroft: it was alchemists who stumbled across it
02:33 PM roycroft: they were trying to turn resistors into gold
02:34 PM roycroft: and like all alchemy experiments, they failed, and were merely able to turn them into magic smoke
02:34 PM JT-Woodshop: for old pc's old os's usually work best... my CHNC is running Ubuntu 10.04
02:34 PM travis_farmer[m]: i think the matrix <--> discord bridge let out the magic smoke ;-)
02:34 PM roycroft: it just took the blue pill by mistake
02:34 PM XXCoder: yeah
02:36 PM travis_farmer[m]: saying i should drop back to debian 10 on my I3 motherboard, JT?
02:37 PM roycroft: no, drop back to minux on your xt, but use the one with the extended memory
02:37 PM roycroft: minux won't fit in 640k of ram very well
02:37 PM roycroft: you'll want at least 4MB
02:38 PM travis_farmer[m]: i still have my production computer running deb10, but i was trying to step up a little bit with the I3 comp and deb11
02:40 PM * JT[m]1 uploaded an image: (265KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/AeguJDGhFkTiIWaoGQfffTSZ/20230113_143910.jpg >
02:40 PM travis_farmer[m]: looks like it is gonna be a good looking bowl :-)
02:42 PM XXCoder: nice indeed
03:14 PM unterhausen: I can't do any board foot calcs in my head any more
03:27 PM unterhausen: beech is half as much as maple
03:33 PM unterhausen: I swear the whole thing with slabs has ruined wood buying
03:34 PM unterhausen: wood doesn't grow on trees you know
03:35 PM CloudEvil: Quick, someone popularise glued-together-bark-tables.
03:37 PM XXCoder: "oh look at that lovely, lovely natural look glued bark table"
03:37 PM XXCoder: "look, theres even river version of that!"
03:37 PM unterhausen: I just saw people are 3d printing wood
03:38 PM unterhausen: for my particular application it might work well
04:03 PM unterhaus: it's always funny when I have to restart irc because I never bothered to get rid of freenode
04:03 PM Tom_L: silly you
04:03 PM unterhaus: there's 12 of us silly people
04:04 PM Tom_L: don't mention libera there or there will be 11
04:04 PM unterhaus: I thought they punted the channel
04:04 PM Tom_L: no idea
04:05 PM roycroft: unterhaus*: those folks up in cogan station - lumber capital log yard, are selling ungraded red oak for the same price as hemlock and pine
04:06 PM roycroft: but yeah, slabs and all that epoxy crap have really screwed up lumber prices
04:06 PM unterhaus: is it kiln dryed?
04:06 PM roycroft: no, it's green
04:06 PM roycroft: but it's cheap
04:07 PM roycroft: i'm looking for an outfit like that around here
04:07 PM unterhaus: I don't have that long to dry it
04:07 PM unterhaus: probably die before then
04:07 PM roycroft: i want to build a trailer, and i'd like some thick, white oak decking material for it
04:07 PM roycroft: green and knotty is fine
04:08 PM XXCoder: can always dry it for a year
04:08 PM roycroft: but i want it to be at least a true 6/4 thick
04:08 PM unterhaus: there used to be a lot of sawmills around here. I guess I'm going to the Anabaptist mills and hope they speak english
04:08 PM roycroft: a year per inch, minimum
04:08 PM Tom_L: make a hot box to dry it in
04:08 PM unterhaus: yeah, looking for 8/4
04:08 PM Tom_L: let the sun do it
04:08 PM XXCoder: ah didnt know about per inch thanks for info
04:08 PM roycroft: yup
04:08 PM XXCoder: tom it slowly cycles air in and out correct?
04:08 PM roycroft: the thicker it is the longer it takes to dry
04:08 PM Tom_L: yes
04:08 PM roycroft: kiln drying isn't always good
04:08 PM unterhaus: if I was making something nice I would definitely buy green
04:09 PM roycroft: in fact, if you're going to steam bend the wood kiln drying is almost always a bad thing to do
04:09 PM unterhaus: yeah, it embrittles the wood usually
04:09 PM Tom_L: i wouldn't consider a hot box kiln drying
04:09 PM unterhaus: case hardens it too
04:09 PM roycroft: walnut is an interesting case
04:09 PM roycroft: kiln drying actually homogenizes the color
04:09 PM roycroft: i.e. the sap wood darkens to more closely match the heart wood
04:10 PM roycroft: but it loses much of it's subtle green and purple and blue colors
04:10 PM roycroft: and the grain gets muddied
04:11 PM XXCoder: while drying other way doesnt?
04:11 PM roycroft: yes
04:11 PM roycroft: air drying enhances the grain and preserves those colors
04:11 PM roycroft: but the sapwood stays light
04:11 PM roycroft: if you're good at dying wood to even out the color, you're best using air-dried walnut
04:12 PM roycroft: if not, then get kiln-dried and know it's going to look "flatter" or more "lifeless"
04:12 PM roycroft: but still better than badly dyed/stained sapwood
04:14 PM markgonz: anyone is familiar with the whb04 pendant?
04:15 PM Tom_L: several here use it i'm sure
04:15 PM Tom_L: what about ti
04:15 PM Tom_L: it?
04:17 PM markgonz: I got it to work with the axis gui for testing and then made a new axis config for my mesa card and now a lot of buttons dont work
04:17 PM Tom_L: where's your backup?
04:18 PM roycroft: i don't know that pendant, other than that folks use it, but i'd do a diff from the new config and the old one
04:18 PM markgonz: I used the same hal file and everything
04:18 PM roycroft: probably some variables got stomped on by the mesa config
04:18 PM markgonz: I guess I need to edit the hal file to match my config but Im a little lost
04:19 PM markgonz: what you mean my backup?
04:19 PM Tom_L: heh
04:19 PM Tom_L: so you didn't make a config backup
04:19 PM * roycroft doesn't know how one can debug a problem if one does not know what one did
04:19 PM Tom_L: i bet roy knows this one...
04:20 PM Tom_L: what's that wood they use for guitar bodies that has a wavy grain to it?
04:20 PM Tom_L: expensive and rare
04:20 PM Tom_L: only grown in very wet regions of washington i think
04:20 PM roycroft: sitka spruce is one of the best tonewoods
04:20 PM Tom_L: no it's not sitka
04:20 PM roycroft: and there are quilted boards of sitka spruce that are very expensive
04:21 PM Tom_L: electric guitar mostly i think
04:21 PM Tom_L: i know they use spruce for most stringed instruments
04:21 PM roycroft: offhand i'm not sure
04:21 PM Tom_L: i was trying to find a pic
04:21 PM roycroft: we have big leaf maple, which grows in wet areas
04:21 PM Tom_L: watched a show about guys that smuggle it
04:21 PM roycroft: ash is a riparian wood, and common around here
04:22 PM roycroft: quilted ash is pretty expensive and very beautiful
04:22 PM roycroft: and it would make a great solid guitar body
04:22 PM Tom_L: yeah that's it i think
04:22 PM markgonz: yeah I need to try to understand more about how the mesa config affects the mpg, I tried just following youtube videos and see if I had luck
04:22 PM roycroft: it's going to get a lot more expensive
04:22 PM roycroft: because the emerald ash beetle has arrived in oregon
04:23 PM roycroft: and we still don't have a really effective way to eradicate it or protect trees from it
04:23 PM Tom_L: its a federal crime to cut a tree unauthorized
04:24 PM Tom_L: https://media.guitarcenter.com/is/image/MMGS7/H11356000001000-00-1600x1600.jpg
04:24 PM roycroft: curly/quilted grain is much less common in ash than in maple
04:24 PM Tom_L: that's what i was looking ofr
04:24 PM Tom_L: for
04:24 PM roycroft: the color of that makes me wonder if it's myrtlewood
04:25 PM roycroft: but it's probably dyed
04:25 PM markgonz: wow that wood pattern is trippy
04:25 PM Tom_L: it grows that way
04:26 PM markgonz: very cool
04:26 PM markgonz: so what kind of music are you guys into?
04:26 PM roycroft: i have a varied and electic musical taste
04:27 PM roycroft: it ranges from medieval chanting to modern jazz, progressive bluegrass, ethnic music from around the world
04:27 PM roycroft: i like jam bands and symphony orchestras
04:28 PM unterhaus: I have a curly oak board. Not sure what I would do with it
04:28 PM unterhaus: it's red oak
04:29 PM unterhaus: saw it in a woodcraft and had to have it
04:29 PM roycroft: if it's just a board, either make it a highlight panel in a piece of furniture or make a pretty box with it
04:29 PM markgonz: ok yes that's interesting and varied, never heard anyone say medieval chanting
04:29 PM roycroft: i'm an odd fellow, markgonz
04:30 PM roycroft: if it's a really nice board, you might consider slicing it into veneers so you can spread the beauty out over a larger piece
04:30 PM * roycroft notes that nobody is arguing with his self-assessment :)
04:30 PM unterhaus: I was going to say you can say that again, but I was afraid you might
04:32 PM travis_farmer[m]: anywhere from Korn, to Beethoven, here :-)
04:32 PM Tom_L: it would probably be easier to say what i don't listen to
04:32 PM markgonz: korn! haha thats cool, just the other day I was watching woodstock 99 documentary
04:33 PM markgonz: I really like limp bizkit to listen while doing house chores and stuff
04:33 PM XXCoder: I used to joke about "The Silence" as my favorite band, having listened to it all my life. but the band actually exists with that name so yeah
04:33 PM * travis_farmer[m] never went to woodstock... too many people...
04:34 PM travis_farmer[m]: lol, XX
04:34 PM Tom_L: didn't think you were that old anyway
04:35 PM roycroft: one of my favorite concerts recently was a eugene symphony performance last october
04:35 PM travis_farmer[m]: for woodstock, original? no, but for 99, i grad HS in 98, so i could have gone...
04:35 PM roycroft: they had a clarinetist who is perhaps the best klezmer musician in the world
04:35 PM roycroft: he was fripping amazing
04:36 PM Tom_L: mama made him practice ehh?
04:36 PM markgonz: cool, Im in my 30s but grew up listening 90s stuff from my older brother
04:36 PM * travis_farmer[m] prefers drums, as an instrument...
04:36 PM roycroft: https://www.youtube.com/watch?v=v71fakQ0-0A
04:37 PM roycroft: that's almost the same performance i saw
04:37 PM roycroft: same piece
04:37 PM Tom_L: no sound here
04:37 PM roycroft: the conductor of the santa rosa symphony is the conductor of the eugene symphony
04:37 PM roycroft: save the link for when you have sound
04:37 PM travis_farmer[m]: hearing-aids not working Tom_L ;-)
04:38 PM Tom_L: no speakers on any of my office PCs
04:38 PM Tom_L: or shop for that matter
04:40 PM travis_farmer[m]: i have sound here... but my headphones are charging (seems an odd concept...)
04:41 PM roycroft: anyway
04:41 PM roycroft: i don't sit around listening to klezmer music all day
04:41 PM roycroft: or any genre, for that matter
04:42 PM roycroft: but i have always liked klezmer music, and david krakauer is undeniably the master
04:42 PM JT-Woodshop: https://content.instructables.com/FTI/R04K/KYOF139O/FTIR04KKYOF139O.jpg
04:42 PM travis_farmer[m]: i have a bluetooth speaker i built from a kit... that is my music in the shop
04:42 PM JT-Woodshop: I wonder how he fit the center plug in?
04:43 PM * roycroft has a decent harmon-kardon receiver in the shop with a cd player and an ipod dock, and a pair of baby advent speakers
04:43 PM travis_farmer[m]: good question. good looking bowl though
04:44 PM roycroft: he probably turned the plug
04:44 PM roycroft: then rough turned the bowl
04:44 PM roycroft: mounted the bowl on a faceplate
04:44 PM roycroft: bored the bottom until the plug fit
04:44 PM roycroft: glued the plug in
04:44 PM roycroft: then did the final turning
04:45 PM roycroft: at least that's probably how i would have done it
04:45 PM roycroft: but i'm not really a turner
04:45 PM roycroft: there may be a much easier way
04:46 PM roycroft: i guess he could have bored the glue-up before the rough turning and inserted the plug into that
04:46 PM travis_farmer[m]: this is the bluetooth speaker kit i have, sounds really good, in case anybody is interested: https://www.parts-express.com/Blast-Box-200-Watt-Portable-Bluetooth-Speaker-Kit-300-7162
04:46 PM roycroft: although i'd be concerned about centering it perfectly
04:46 PM roycroft: the way i described would center it easily
04:47 PM travis_farmer[m]: i think he did it as a plug, after the bowl was rough turned
04:47 PM roycroft: it's a cross-grain plug, though, not an end grain plug
04:47 PM roycroft: so it's a very shallow plug, but that's still doable
04:48 PM travis_farmer[m]: could have been thicker, and turned down after install
04:48 PM JT-Woodshop: I was thinking of chucking the layer up and boring the hole with a forstner bit then turning the plug to fit
04:49 PM JT-Woodshop: but yep centering is a something to worry about
04:50 PM JT-Woodshop: if you glue up the layers in the lathe then centering is pretty easy
04:50 PM travis_farmer[m]: if the plug sticks out on the bottom, then it could go into the chuck
04:50 PM roguish[m]: JT-Woodshop: very nice looking bowl. plenty good popcorn
04:51 PM JT-Woodshop: not mine
04:51 PM roguish[m]: well get with it....
04:52 PM roycroft: you could do it that way, jt-woodshop
04:52 PM roguish[m]: JT-Woodshop: finally got a trial run of thread milling an m28x1.5 external.
04:52 PM roycroft: my concern about pre-plugging is that it could be tricky to index on the exact center of the plug
04:53 PM roycroft: it seems it would be easier to at least rough turn the bowl first, because that would be easier to center on the face plate
04:55 PM XXCoder: https://youtu.be/5XlTkGEO564
04:55 PM XXCoder: pretty cool
04:55 PM XXCoder: he made wood lathe autofeeder too lol
04:56 PM XXCoder: and inside diameter version too
04:59 PM XXCoder: basically recreated metal lathe cross feed etc also lol
05:20 PM Tom_L: roguish[m], how'd the threads turn out?
05:45 PM * JT-Woodshop calls it a day
07:58 PM CaptainHindsight: test, 3,2,1....11 👀
07:59 PM CaptHindsight[m]: 👍️
08:04 PM skunkworks[m]: yes
08:04 PM Tom_L: skunkworks[m], you see the big iron i got to see this week?
08:04 PM XXCoder: yo
08:13 PM roycroft: yay! i got my final logo files!
08:13 PM XXCoder: congats
08:13 PM roycroft: the last delay was on me
08:13 PM roycroft: i had to pick the color
08:13 PM XXCoder: I like that mini table saw better https://youtu.be/H3jl3puKNgo
08:13 PM roycroft: and to do that i had to drive an hour away to borrow a pantone spot color chip set
08:14 PM roycroft: then drive back home
08:14 PM XXCoder: I saw others that have horror of table held up by 2 bolts
08:14 PM XXCoder: which means it could pop down and fully expose saw
08:14 PM roycroft: and then set up a lighting system that gave me the correct color tempature
08:14 PM roycroft: then compare thousands of color chips
08:15 PM roycroft: i don't know the magic behind how pantone do this, but to get the correct color temperature (which is daylight), the last chip in the book is two different beige colors
08:15 PM roycroft: if you have the correct color temperature, they look identical
08:15 PM roycroft: if you're too hot or too cold, they look different
08:23 PM XXCoder: 128 usd, bit more than expected, but then $40 one risks your fingers
08:25 PM roycroft: proxxon make a nice miniature table saw
08:25 PM roycroft: theirs is probably the best-known
08:25 PM roycroft: i don't know if it's the best
08:26 PM XXCoder: big jump in qyality, and even have tilting
08:26 PM roycroft: https://www.youtube.com/watch?v=8wEpFkyTCm4
08:26 PM XXCoder: yep
08:26 PM roycroft: its not as small as myfordguy's
08:26 PM roycroft: but it's still pretty small
08:27 PM XXCoder: well the other one would be fine for small basic cuts, angles only along xy
08:36 PM roycroft: i have no idea what either machine costs
08:36 PM roycroft: so i'm not trying to directly compare the two
08:37 PM XXCoder: your linked one is nearly $500
08:37 PM roycroft: that does not surprise me
08:37 PM roycroft: it was probably $300 a couple years ago :)
08:37 PM XXCoder: probably
10:05 PM Tom_L: MDI: M19 R0 P1 result: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/orient_mdi_input.png
10:05 PM Tom_L: what am i missing to get the spindle.0.on?
10:06 PM Tom_L: pwmgen.00.enable maybe
10:06 PM Tom_L: need an or2 component i think for that
10:09 PM ZincBoy[CAON][m]: I use a different orient approach than you but I OR the spindle.0.enable signal with my orient-enable and send the result to the physical drive enable pin.
10:10 PM Tom_L: i had it working this way once but it was with a different spindle motor
10:10 PM Tom_L: and i've slept since then...
10:11 PM Bleepshop: Tom_L: Did you remember to sacrifice a rubber chicken before you started? ;D
10:11 PM Tom_L: oh damn..
10:12 PM Tom_L: ZincBoy[CAON][m], i'm going off andy's diagram
10:13 PM Tom_L: https://wiki.linuxcnc.org/uploads/orient.svg
10:14 PM Tom_L: but i've got 2 issues now
10:14 PM Tom_L: with the normal M3, the spindle runs away.. aparently the feedback is broken... and on orient, it doesn't turn on
10:15 PM Tom_L: i'm not sure what broke the first one
10:16 PM ZincBoy[CAON][m]: I am pretty sure I added the OR for the enables because it was needed. My VFD has an enable input that is not in that diagram. That diagram is missing any way to turn off the spindle. it will always be enabled forward or reverse.
10:16 PM Tom_L: right
10:16 PM Tom_L: well, no it does turn off
10:17 PM Tom_L: i need to review what i've changed
10:18 PM Tom_L: S100M3 runs away but M5 will turn it off still if that's what you're referring to
10:20 PM ZincBoy[CAON][m]: In the orient diagram you linked, there is no enable to the drive. Only fwd/rev/speed. In a real system you need the enable as well. That is where or-ing the enables comes in. The runaway is likely due to missing feedback or mistuned PID.
10:21 PM Tom_L: spindle.0.on enables pwmgen.00.enable and a gpio pin to enable the analog signal on the board
10:22 PM Tom_L: so if i add an or2 there along with mux2.0.sel that should switch them on in either condition
10:23 PM Tom_L: and send that to the pwmgen.enable etc
10:24 PM Tom_L: when mux2.0.sel is unselected, pid.1 is active and when it is enabled, pid.0 is enabled
10:24 PM Tom_L: per that diagram
10:25 PM Tom_L: i need to fix the spindle runaway first though
10:26 PM ZincBoy[CAON][m]: The mux is for the velocity signal to the drive (vfd-speed). You also need the enable which is from the OR. You will have at least two signals going to the drive, Speed and Enable. You may have a third signal or fourth signal to control direction if the Speed input is not bidirectional.
10:27 PM Tom_L: i'm not doing bidirectional on orient right now
10:28 PM Tom_L: and normal use it is triggered by gpio from spindle.0.forward status
10:29 PM Tom_L: so if i want bidirectional orient, i would fix it there
10:29 PM ZincBoy[CAON][m]: That has nothing to do with the signals to the drive. The position PID might be very difficult to tune if you don't have bidirectional spindle control. Think of a control loop that only lets you move in one direction.
10:38 PM Tom_L: i'll pick it up again tomorrow.
10:38 PM Tom_L: amongst distractions
