12:38 AM Jayar: anyone know anything about the AnnoyTools cnc controller?
12:48 AM Jayar: got a question about the PWM on it, if i can use it as input or if its just an output for speed control
12:50 AM -!- #linuxcnc mode set to +v by ChanServ
12:50 AM -!- #linuxcnc mode set to +v by ChanServ
01:00 AM boostedcabbage[m: if you're talking about that 48v output, that's connected to a mosfet and isn't bidirectional
01:02 AM Jayar: the 3-prong plug to the right of the yellow pin header is the pwm... and im not usin any inputs, just the usb-b plug that comes from the pc... i guess i could tap into the USB plug (bottom left next to the reset button), thats used for the offline controller
01:03 AM Jayar: theres another 12v pwm for laser control also, but i'm sure thats output
01:05 AM boostedcabbage[m: how about the limit switches and things?
01:06 AM boostedcabbage[m: do you have a hal config so i can see the nets/pins?
01:13 AM * boostedcabbage[m uploaded an image: (105KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/cKOaoycolrYDjnCdlisLooSO/image.png >
01:13 AM boostedcabbage[m: pcw-home: map these lines to lincurve eh?
02:25 AM * boostedcabbage[m uploaded an image: (42KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/NlGemOGqKPEhOIEbscZnhYzV/image.png >
02:25 AM boostedcabbage[m: so this will interpolate RMS power input (0-1) and have firing angle/timing as output
02:30 AM Deejay: moin
02:30 AM boostedcabbage[m: good morning
04:31 AM mits[m]: ffff, again I've got my linuxcnc box with an unknown password because I can't make it be empty
04:31 AM mits[m]: (yes, I know how to root my own box, I'm just annoyed at having to do it)
04:35 AM mits[m]: oh cute, the root account is locked so the lazy way is blocked
04:38 AM rmu: mits[m]: first thing after installing new box: enable ssh, install appropriate authorized_keys
04:39 AM mits[m]: it's not attached to the network
04:40 AM mits[m]: this is why a while ago I was in here begging for a way to install the live image onto my hard drive
04:40 AM mits[m]: tried tons of methods... nothing works so far
04:42 AM Tom_L: login as root and 'chpasswd user'
04:42 AM mits[m]: root is locked
04:42 AM mits[m]: the installer by default disables it
04:43 AM mits[m]: this is typical, they want you to get used to using sudo
04:43 AM rmu: mits[m]: get usb to ethernet adapter, plug it in, connect laptop, ssh
04:43 AM Tom_L: so from now on just tell us what the password is
04:43 AM rmu: or wlan
04:43 AM mits[m]: how does the linuxcnc live image get built
04:43 AM mits[m]: is there some human doing the steps
04:43 AM mits[m]: or is there a CI system/buildbot somewhere?
04:44 AM Tom_L: buildbot
04:44 AM rmu: mits[m]: alternatively, you could debootstrap onto empty harddrive, and install linuxcnc from buildbot packages manually
04:44 AM Tom_L: afik
04:44 AM rmu: alternative to live cd install
04:45 AM mits[m]: I can do that, but I want the setup that is the live image
04:46 AM mits[m]: it has a root account with no password, and various auto login bits configured so you don't have to remember them one at a time
04:48 AM mits[m]: AHA, it does most of that with debian preseed
04:48 AM rmu: now it's too late probably. have to fix it with booting from usb thumb drive or live cd, chroot, chpasswd
04:51 AM mits[m]: I mean, it is... cause I wiped the disk in annoyance
04:52 AM rmu: oh, unfortunate. next you announce you change over to mach3?
04:53 AM JT[m]: Morning
04:53 AM mits[m]: no?
04:53 AM mits[m]: I'm annoyed at myself
04:53 AM mits[m]: not linuxcnc itself
04:53 AM mits[m]: I wasn't going to remember the user account or password I used
04:59 AM rmu: typical progression here on #linuxcnc is install linuxcnc, have a bunch of hardware (breakout boards and or mesa) that are not really suitable for the task, get frustrated immediately because of inability to RTFM or ask coherent question and the wipe everything out and go to mach3/mach4 or grbl. so sorry for my snarky comment.
05:00 AM mits[m]: this is me trying to test new stuff
05:00 AM mits[m]: I've got my working machine in the garage
05:00 AM mits[m]: I won't call myself an expert or anything, but I'm not switching to something else
05:06 AM JT[m]: Tom_L reinstalling Debian on the Cave pc
05:06 AM JT[m]: Network configuration worked this time
05:21 AM travis_farmer[m]: G'Morning ☕️ (yes, i just got up...)
05:35 AM mits[m]: do any of you folks use newer kernels than the one linuxcnc ships with?
05:35 AM travis_farmer[m]: yes
05:35 AM mits[m]: my working machine is raspi, so I'm leaving that alone
05:35 AM mits[m]: but I'm switching to an amd64 box and I was considering using something newer than buster
05:36 AM mits[m]: as long as it 'probably works'
05:36 AM travis_farmer[m]: i use debian 11 (5.10 kernel, i think)
05:38 AM JT[m]: I have Ubuntu 10 on my lathe
05:45 AM mits[m]: I like how ubuntu doesn't ship an rt kernel for free, they want you to sign up for ubuntu pro and use their custom tuned one
05:50 AM Loetmichel: *GNAAAH*... FIFTH time the CNC mill guy comes by getting on my nerves with "part still doesent fit"... Thats what happens when haf a dozen workers crowd you while trying to redo the CAD/CAM files. accidentally used a 2mm mill bit for the outline instead of the 6mm thats in the machine. Result was "a bit too small". :(
06:04 AM -!- #linuxcnc mode set to +v by ChanServ
06:08 AM JT-Cave: when I installed debian 11 I didn't have an internet connection so I could not select a mirror... so debian only put security in the sources.list... took a while to sort that out
06:17 AM -!- #linuxcnc mode set to +v by ChanServ
06:29 AM -!- #linuxcnc mode set to +v by ChanServ
06:34 AM JT-Cave: well I was going to clone mesact but I don't have git installed and apt dist-upgrade has 2 hours to go...
06:46 AM Tom_L: fun
06:47 AM JT-Cave: at least this pc is back up and running... somewhat
06:48 AM JT-Cave: deb 11 doesn't recognize the display but it's not stuck on 800 x 600 like before so maybe I'll just deal with 380 x 2160 for a while
06:50 AM travis_farmer[m]: 380 x 2160? what aspect ratio is that?
06:52 AM JT-Cave: 3840
06:52 AM travis_farmer[m]: oh, lol
07:03 AM JT-Cave: the annoying thing about using my mobile hot spot to get internet is I can't get to my LAN
07:10 AM JT-Cave: 1h 10m left to update d11
07:14 AM Tom_L: i thought you had that worked out
07:16 AM JT-Cave: nope it didn't work
07:17 AM JT-Cave: router now has an estimated ship date of 3-20 to 3-26
07:18 AM Tom_L: i thought he was trying to sell internet to ppl... not a good way to go about it
07:24 AM JT-Cave: my d/l speed is throttled back to 75kB/s lol
07:25 AM * JT-Cave is off to start his chicken day
07:26 AM JT-Cave: at least I "think" my Mesa order is shipping complete :)
07:47 AM satiowadahc[m]: I've been running 5.10 preempt for awhile seems pretty solid. I accidentally ran the latest Ubuntu kernel without installing preempt and it was rock solid until I tried running halscope.
07:48 AM satiowadahc[m]: I think it was 5.16?
07:48 AM JT-Cave: LOL my wife didn't even notice I cut 2" off my beard this morning
07:48 AM JT-Cave: 35m left to update here
07:59 AM Loetmichel: HARHAR... just installed the Nvidia GPU driver instead of the std win11 driver on my new Company notebook. MAN is Solidworks FAST now. Now its even useable on a part with 4500 air holes in it :)
08:02 AM skunkworks[m]: Loetmichel: you should be running linux - then pass the gpu to a windows vm.. lol.. Why? Because of course....
08:03 AM Loetmichel: company notebook. Not my decision. Company policy is win11.
08:32 AM sensille: skunkworks[m]: don't forget to map the output back to linux with lookingglass
08:42 AM skunkworks[m]: sensille: I just remote into it. My laptop is muxless - so there isn't a physical port to hook to.
08:54 AM skunkworks[m]: always wanted to try looking glass..
09:53 AM sensille: it mostly works
09:54 AM sensille: but it regularly misses updates you have to move over the area with a mouse to force an update
10:14 AM skunkworks[m]: freerdp seems more than fast enough for cad (fusion) but I have been playing with freecad more. Haven't touched fusion in years now.
10:14 AM mits[m]: anybody here use mesa card as a frequency counter on mill spindles?
10:15 AM mits[m]: I'm trying to figure out if it's possible
10:17 AM unterhausen: You just want to monitor the spindle speed?
10:18 AM mits[m]: yeah
10:18 AM skunkworks[m]: I think everyone does that.. 🙂
10:18 AM mits[m]: I thought the usual thing is to leave it open loop, or have an encoder for position
10:19 AM mits[m]: though I suppose I could try to convert this to a gray code
10:19 AM unterhausen: my spindle has a gear on it, you can set it up with a gear tooth monitor
10:19 AM unterhausen: looking at rigid tapping setups would be a start
10:20 AM mits[m]: well that's the thing, I think... rigid tapping setups will use encoder inputs
10:20 AM mits[m]: I'm trying to ask if a mesa card can just do frequency counting
10:20 AM mits[m]: like pulse per revolution
10:21 AM bjorkintosh: how many mesa cards are there?
10:22 AM mits[m]: where?
10:22 AM bjorkintosh: sorry. i meant, how many types.
10:22 AM mits[m]: oh, I am mostly just talking about the hostmot type
10:23 AM mits[m]: so one type... but that firmware is configurable
10:23 AM bjorkintosh: ah I see.
10:40 AM skunkworks[m]: mits what mesa hardware do you have?
10:40 AM mits[m]: a 7C80, a 7I76, a 7I96, and some other IO cards that I can't remember
10:40 AM mits[m]: s/7I76/7I76e/
10:40 AM mits[m]: s/*//, s/7I96/7I95/
01:55 PM boostedcabbage[m: you mean counter mode vs quadrature mode?
01:56 PM boostedcabbage[m: #only require A phase - counter mode instead of quadrature mode
01:56 PM boostedcabbage[m: setp encoder.0.counter-mode 1
02:32 PM boostedcabbage[m: yay.. my spindle turns on. Sxx is producing expected scaled RMS power. now to just PID
02:32 PM boostedcabbage[m: lincurve was a good idea pcw-home
02:55 PM boostedcabbage[m: also, if you guys want that bridge fixed, i could help with the character encoding
02:58 PM boostedcabbage[m: &apos; should be decoded
03:00 PM cabbagedreams: test ' " < > &
03:21 PM TurBoss8676[m]: that would be awesome? can I DM you some info if you like?
03:21 PM boostedcabbage[m: sure
03:23 PM TurBoss: thanks
04:01 PM travis_farmer[m]: sadly, the warm rain has taken it upon itself to become the dreaded snow...
04:12 PM TurBoss8676[m]: Hello, can somebody from irc send this? "'&<#>
04:12 PM TurBoss8676[m]: thanks
04:13 PM Rab: "'&<#>
04:14 PM TurBoss8676[m]: Thanks!
04:14 PM Rab: Any time!
04:15 PM travis_farmer[m]: still the apos issue?
04:15 PM TurBoss8676[m]: yup 😄
04:24 PM travis_farmer[m]: hmmm, seems to be blowing a blizzard now :-(
04:26 PM roycroft: it's just nasty here today
04:26 PM roycroft: not cold enough to be brisk
04:27 PM roycroft: not warm enough to be comfortable
04:27 PM roycroft: and raining constantly
04:27 PM roycroft: not snow, which is always fun and an excuse to stay home and drink hot cocoa
04:27 PM roycroft: not sunny and nice
04:27 PM roycroft: just uncomfortably nasty
04:39 PM seb_kuzminsky: hello, Guest16
04:40 PM travis_farmer[m]: ????
04:40 PM XXCoder: travis_farmer[m]: guest16 come in irc
04:41 PM XXCoder: join/leave dont show in discord and matrix. matrix and discord quotes dont show in irc
04:41 PM travis_farmer[m]: oh, didn't see it on matrix
04:41 PM XXCoder: its not perfect
04:41 PM travis_farmer[m]: not like me? ;-)
04:44 PM -!- #linuxcnc mode set to +v by ChanServ
05:08 PM InnerBushman[m]: what CAM do you guys use for XYZA machines?
05:09 PM InnerBushman[m]: when I was upgrading my DIY router I bought one extra stepper servo thinking I'll use it for 4'th axis some day.
05:11 PM XXCoder: some people just use xyz and "roll" one axis
05:12 PM InnerBushman[m]: roll? as in manually roll it and stop, then work in the other 3 axis?
05:13 PM JT-Shop: do some op, rotate, do another op
05:14 PM InnerBushman[m]: i only once used the 4'th axis on my DIY router. but i cheated by scaling one axis to match the degree to mm and then treat the surface of a cylinder like a flap plane
05:14 PM InnerBushman[m]: what i'm thinking right now is something more complex, where the CAD/CAM does the rotating
05:15 PM InnerBushman[m]: i've noticed FreeCAD has rotation in the Path workbench now
05:15 PM InnerBushman[m]: but i was curious if someone already is using some other CAM for that purpose
05:35 PM roguish[m]1: windy as heck here. about to blow the dogs off their chains...
05:42 PM JT-Shop: getting a large Mesa order tomorrow
05:42 PM roguish[m]1: boards coming in?
05:42 PM JT-Shop: yup
05:42 PM roguish[m]1: cool
05:43 PM JT-Shop: yep everything I ordered except one was in stock
05:54 PM perry_j1987: hows it going
05:54 PM JT-Shop: done gluing up the rings...
05:55 PM XXCoder: nice
05:55 PM travis_farmer[m]: snow blowing, and power flickering... acts like a good time to sign off and go to bed...
05:55 PM JT-Shop: it's actually going very well
05:56 PM XXCoder: jt if you havent went to umm wedding? yet, maybe you can make fancy IOU plate with cnc lol
05:56 PM JT-Shop: we leave Thursday
06:01 PM JT-Shop: I thought I had f engrave installed this pc but not
06:10 PM Tom_L: InnerBushman[m], my cam supports rotary but somewhat limited
06:11 PM InnerBushman[m]: what are you using?
06:11 PM Tom_L: commercial
06:11 PM Tom_L: smartcam
06:11 PM Tom_L: not real robust but it does rotary
06:12 PM Tom_L: if you're needing a commercial product i'd probably go with Mastercam
06:13 PM Tom_L: when i got mine, smartcam was more widely used than mastercam but they were bought out a couple times and kinda died out
06:13 PM Tom_L: post is easy to edit
06:14 PM Tom_L: JT-Shop, getting any of those single analog boards?
06:14 PM Tom_L: spinx or whatever it's called
06:16 PM JT-Shop: I ordered some spinx1 but didn't get any
06:18 PM Tom_L: InnerBushman[m], start around 2:05 https://www.youtube.com/watch?v=pvDBfJQT2Ec
06:18 PM Tom_L: my scale was off on the rotary so it's uber slow up to that point
06:18 PM Tom_L: first test cut
06:24 PM InnerBushman[m]: i've noticed it's not following through on the helix moves, even tho the line is technically straight in those axes interpolating.
06:25 PM Tom_L: it pauses between gcode lines
06:25 PM Tom_L: not sure a way around that
06:25 PM InnerBushman[m]: hmm....
06:25 PM InnerBushman[m]: does it do that on flat things?
06:25 PM Tom_L: no
06:25 PM Tom_L: it's likely the cad cam
06:25 PM InnerBushman[m]: like regular G1 on XY?
06:26 PM Tom_L: it's like 30 yrs old
06:26 PM Tom_L: not great support for rotary
06:26 PM Tom_L: but i don't need much, it was more a testing exercise for me
06:26 PM InnerBushman[m]: also, you have very conservative accelerations on this rotary axis.
06:27 PM Tom_L: yeah, when i did that one, i was still tuning the rotary and the cam post
06:27 PM Tom_L: it's not a production machine..
06:29 PM Tom_L: practically i would likely use it more as an indexer
08:23 PM unterhaus_: there was a problem with conversational programming on probe basic recently, wasn't there?
08:23 PM unterhaus_: someone asking about it on fb lcnc group
08:25 PM bjorkintosh: there's a fb group?
08:25 PM unterhaus_: yeah
08:26 PM unterhaus_: it's called linuxcnc users. I don't know who set it up
08:27 PM bjorkintosh: how fun. I'm not on FB but good to know.
08:27 PM unterhaus_: Steven Jones and Martin King are administrators
08:38 PM * roycroft has never been on facebook but can't imagine anything about it being "fun"
08:42 PM unterhaus_: you may not know anything about facebook, but it knows everything about you
08:42 PM unterhaus_: world's most elaborate identity theft scheme and you don't even have to have an account to be a victim
08:43 PM roycroft: i don't think it knows everything about me, but it likely knows a lot more about me than i would like
08:44 PM unterhaus_: we'll never know unless you sign up for an account
08:44 PM roycroft: and yes, i believe mark zuckerberg and his ilk are thieves
08:44 PM roycroft: but i don't think about that often
08:45 PM roycroft: i just live my life and avoid cretins like that as best i can
08:45 PM unterhaus_: Maybe not really thieves, but they will sell you out to entities like insurance companies
08:46 PM roycroft: my personal information belongs to me
08:46 PM roycroft: if they somehow acquire it without my consent and profit from it that it thievery
08:46 PM unterhaus_: they are really good at disambiguating disparate data sources
08:47 PM unterhaus_: okay, if that's the sense of thieve we are agreeing on, they are
08:47 PM roycroft: i'm pretty good at having multiple email addresses, using vpns, and using private browser sessions, amongst other things
08:47 PM roycroft: i'm not naive, and i have no illision that i've been able to keep my personal information completely private
08:47 PM skunkworks[m]: lol - google and facebook have a real hard time figuring out what to serve me for ads..
08:47 PM unterhaus_: now I really sorta want to know what they have on you
08:48 PM skunkworks[m]: Lately it has been mint mobil - which I tried for a year..
08:48 PM roycroft: but i do my best to make it difficult for them to paint an accurate picture of me
08:48 PM roycroft: i'm on mint right now
08:48 PM unterhaus_: i had my facebook profile totally falsified. Every job, etc was an unterhausen that had died
08:48 PM roycroft: my boss changes cell carriers whenever he thinks he can save a couple dollars
08:48 PM skunkworks[m]: or - you looked at a telescope.. Let me server you all types of telescopes..
08:49 PM roycroft: of course, he always spends way more on the migration than he saves in recurring costs before the next time he moves on
08:49 PM boostedcabbage[m: extraordinary measures are required to have privacy these days
08:49 PM roycroft: he does the same thing with banks - he switches bank accounts pretty much annually
08:49 PM unterhaus_: then facebook tried to connect me up with people who knew the deceased and I realized people could be hurt
08:49 PM skunkworks[m]: I go all over. Currently spending 25 a month with visible (verizon non contract) so far so good.
08:49 PM roycroft: and it always takes him a month or two to get the new bank sorted and get his auto-pays fixed up
08:50 PM roycroft: and he generally overdraws the account several times while trying to get everything moved around
08:50 PM roycroft: so again, paying more in stupid fees than he saves on recurring costs
08:50 PM roycroft: not to mention all the time it takes
08:50 PM skunkworks[m]: I was with tracfone for a long time.. but they don't have unlimited..
08:51 PM roycroft: it's hard to work for someone who can't see past the end of his nose
08:51 PM unterhaus_: i guess everyone on the qtpyvcp discord is asleep
08:51 PM unterhaus_: bastages
08:51 PM * roycroft needs to make dinner
08:51 PM roycroft: i'm not adjusted to summer time yet
08:51 PM XXCoder: people who spend $100 to save $10 tend to be
08:51 PM roycroft: broke and whiney
08:52 PM roycroft: did i finish it right? :)
08:52 PM XXCoder: lol workable
08:53 PM roycroft: then there's the blame of the government
08:53 PM roycroft: "i overdrew the bank account again and they charged me a huge fee - it's all the government's fault!"
08:53 PM XXCoder: recent bank issues makes me glad I dont have bank account once again
08:53 PM roycroft: those issues would not have affected you at all
08:54 PM roycroft: i'm actually kind of pissed off at the bailout
08:54 PM XXCoder: bank is not being bailed out
08:54 PM roycroft: no
08:54 PM roycroft: but the depositors are
08:54 PM roycroft: including the ones not covered by fdic insurance
08:54 PM XXCoder: why? I prefer that than bailing out bank bad decisions
08:54 PM roycroft: "it's not going to cost the taxpayers anything"
08:54 PM unterhaus_: for the most part, the deposits still exist
08:54 PM roycroft: well, yes it is
08:55 PM roycroft: because that bailout is coming out of the fdic insurance fund
08:55 PM roycroft: and the rates for fdic insurance will go up because of that
08:55 PM Tom_L: i wonder how often that fund has been used
08:55 PM roycroft: that cost will be passed on to bank customers in the form of higher fees and lower interest rates on deposits
08:55 PM roycroft: fairly frequently
08:55 PM roycroft: small banks fail fairly often
08:56 PM roycroft: this was a huge bank, though
08:56 PM Tom_L: and usually get swept up by bigger banks
08:56 PM roycroft: yes
08:56 PM unterhaus_: generally the government does okay with these bailouts. They made money off of tarp, for example
08:56 PM roycroft: the british branch of svb were sold to barclay's for £1
08:57 PM unterhaus_: Rod Webster is on that fb group
08:57 PM roycroft: the canadian branch just closed
08:57 PM roycroft: it is no more
08:57 PM roycroft: it's pining for the fjords
08:57 PM roycroft: bereft of deposits, it has ceased to be
08:58 PM roycroft: anyway, the depositers will get all their money back
08:58 PM roycroft: it's the investors who own the bank that lose
08:59 PM roycroft: and from what i hear, the ceo should be prosecuted and imprisoned - if what is being said is true, he is personally responsible for the failure
08:59 PM roycroft: but he'll probably just go head up another bank
09:00 PM roycroft: anyway, none of that affects me, other than having to hear all the whining and conspiracy theories about it
09:00 PM XXCoder: yeah those is annoying
09:00 PM roycroft: and of course, the republicans are blaming biden for it
09:00 PM roycroft: and the democrats are blaming the former president for it
09:00 PM roycroft: and they're all full of it
09:14 PM Tom_L: that's how the game is played
09:19 PM roycroft: it is, and it's a stupid game that is very harmful
09:20 PM boostedcabbage[m: without any accountability
09:21 PM roycroft: oh, there's accountability, every 2 or 4 or 6 years
09:21 PM roycroft: but the voters let their tribalism get in the way of their better judgement
09:21 PM roycroft: so they keep reelecting the same people
09:22 PM roycroft: make parts, not laws!
09:22 PM roycroft: that's what i ay
09:22 PM roycroft: say
09:22 PM boostedcabbage[m: yes
09:22 PM boostedcabbage[m: PID tuning time
09:22 PM roycroft: speaking of which
09:23 PM roycroft: the display on my pid controller that i bought last year for my heat treatment oven is not working
09:23 PM roycroft: i'm disappointed
09:23 PM roycroft: it's the first product i've ever purchased from auber instruments that has failed in any way
09:25 PM roycroft: fortunately they haven't gone up in price as much as most things
09:26 PM roycroft: $71.98 last april; $72.98 now
09:26 PM roycroft: i can live with that
09:26 PM unterhaus_: what tech display?
09:27 PM unterhaus_: lcd,led, oled
09:27 PM roycroft: ooh, it has a 12 month warranty
09:27 PM roycroft: and it's been 11 months :)
09:28 PM boostedcabbage[m: i'm not even sure these nets are sane. going to start upping P until it oscillates
09:28 PM roycroft: led
09:28 PM unterhaus_: weird it would go out
09:28 PM unterhaus_: good think about the warranty though
09:29 PM roycroft: i haven't spent more than a minute checking it out
09:30 PM roycroft: but now that i know it's under warranty, and the warranty expires soon, i'll make it a priority to investigate more fully
09:32 PM unterhaus_: I was looking to see if they had externally controllable models. Seems like BT or WIFI is it
09:32 PM unterhaus_: the one my client has can be controlled over serial, but the protocol is awful
09:33 PM unterhaus_: my favorite part is a command has to be bitwise xor-ed
09:33 PM unterhaus_: at the end for a checksum. Try doing that by hand
09:33 PM roycroft: i've purchased about 10 pid controllers from them, and i've been very happy with them
09:33 PM roycroft: and i lied earlier
09:33 PM unterhaus_: that's a lot of beer
09:33 PM roycroft: i did have two of them fail
09:34 PM roycroft: but that's because the control panel in which they were mounted caught on fire and melted them
09:34 PM roycroft: i won't blame auber instruments for that
09:34 PM unterhaus_: what caught on fire, the beer?
09:36 PM roycroft: the control pane
09:36 PM roycroft: l
09:36 PM roycroft: i had a towel on the top of the panel to keep the dust off
09:36 PM roycroft: i was doing some welding on the other side of the shop - a good 8m away
09:36 PM unterhaus_: their wifi controlled controllers look pretty useless, need an app
09:37 PM roycroft: but of course, a spark flew across the room and landed on the towel
09:37 PM unterhaus_: seems particularly unlucky
09:37 PM roycroft: by the time i ran over to the control panel the front panel instruments were pretty melted
09:37 PM roycroft: it was quite unlucky, and quite unexpected
09:39 PM roycroft: but it was a phoenix opportunity, literally
09:39 PM unterhaus_: does debian 10 have python 3?
09:40 PM roycroft: there were a number of modifications i had wanted to do the control panel, which required a complete rebuild of the front panel
09:40 PM roycroft: i had avoided doing that
09:40 PM roycroft: but then i had no choice
09:41 PM * roycroft doesn't remember, and is looking for a debian 10 machine
09:41 PM Tom_L: since jt's fiasco i've been prompted to check and see if my router would take advantage of a usb wifi dongle and so it seems it will
09:41 PM roycroft: $ cat /etc/debian_version
09:42 PM roycroft: 10.9
09:42 PM roycroft: $ python3 --version
09:42 PM roycroft: Python 3.7.3
09:42 PM roycroft: that machine needs to be updated
09:42 PM Tom_L: You can also create internet connections or backup connections thru a 3g/4g USB dongle.
09:42 PM Tom_L: yay
09:45 PM Tom_L: even gives a list of brand/model by country
09:47 PM unterhaus_: everyone is telling me to update to 12
09:47 PM Tom_L: why?
09:47 PM Tom_L: and why do you feel the need to?
09:47 PM unterhaus_: I don't
09:48 PM Tom_L: i might suggest if you can't resist the urge to do it on a spare ssd
09:48 PM unterhaus_: but if I was going to run probe basic I might because the devs want me to
09:48 PM Tom_L: i have a pile of ssd with debian 10-12 and maybe 13 on them
09:49 PM unterhaus_: it would be no great loss to change over to 12, I think
09:49 PM unterhaus_: for me
09:49 PM Tom_L: 12 (bookworm) is still not a full release
09:50 PM unterhaus_: that's why I didn't install it 2 weeks ago
09:50 PM Tom_L: then there are 13(Trixie) and 14(Forky) and of course sid
09:50 PM unterhaus_: they left the 'ou' off the end of the code name for 14
09:52 PM roycroft: debian 12 will probably not be released until fall
09:53 PM roycroft: i'll need to be completely off debian 10 by then
09:53 PM Tom_L: i've been using 12 for some time now
09:53 PM roycroft: i don't like running systems more than one major release behind
09:53 PM Tom_L: i'm still running 7 (wheezy) on the mill
09:54 PM roycroft: i also don't like running bleeding edge code unless there's a compelling reason to do so
09:54 PM roycroft: i'll start experimenting with debian 12 when the general release is out
09:54 PM roycroft: and i'll probably wait until 12.1 before deploying it in production
10:02 PM XXCoder: pecan and strawberry pies yummy
10:02 PM XXCoder: happy pi day all
10:10 PM boostedcabbage[m: this isn't currently tunable with how it's setup :/ ramps up and oscillates hard eventually with any I gain (even with very low P gain)
10:11 PM boostedcabbage[m: it'll take its sweet time ramping up too
10:12 PM XXCoder: so it dont have convergance point on settings?
10:12 PM XXCoder: sounds like need to change something
10:14 PM boostedcabbage[m: yeah. i can't reach a set point
10:14 PM boostedcabbage[m: unless it's very slow
10:24 PM boostedcabbage[m: https://github.com/boostedcabbage/linuxcnc/blob/delayshot/configs/my-lathe/my-lathe.hal
10:26 PM boostedcabbage[m: maybe someone could look at my nets and scaling and see something. it might be on drugs
10:26 PM roycroft: i didn't eat any pie today
10:27 PM roycroft: but i did some trigonometry earlier
10:27 PM roycroft: is that good enough?
10:27 PM boostedcabbage[m: probably
10:27 PM XXCoder: good enough. arent you hungry for pie tho? lol
10:30 PM boostedcabbage[m: are there any tools to roll chart pin floats like the halmeter?
10:31 PM boostedcabbage[m: hmm.. can halmeter show me floats?
10:31 PM boostedcabbage[m: lol.. halscope
10:35 PM boostedcabbage[m: ah.. it can show signals. nice
10:36 PM Tom_L: is boostedcabbage[m sauerkraut?
10:37 PM Tom_L: just pondering things...
10:37 PM boostedcabbage[m: i seem to be right now
10:40 PM Tom_L: is this the zero crossing thing you're working on?
10:40 PM Tom_L: triac or something
10:41 PM boostedcabbage[m: yeah
10:41 PM Tom_L: you seem to have come quite a ways in a few days
10:43 PM Tom_L: you don't use FF0 on this?
10:46 PM Tom_L: interesting.. i've never used lincurve
10:47 PM boostedcabbage[m: the intent is to have scale 0-1 for RMS power timings for the triac
10:47 PM boostedcabbage[m: i think that part might be right
10:47 PM boostedcabbage[m: the big picture here is still a bit fuzzy in my head
10:48 PM Tom_L: what is the reason for using a triac?
10:49 PM Tom_L: i used one on my reflow toaster oven
10:49 PM boostedcabbage[m: there isn't a good one. it's a brushed dc motor. i just don't have anything else to use. burned up a power mosfet i was going to use. a challenge i suppose
10:49 PM Tom_L: using a zero crossing chip in front of it?
10:51 PM boostedcabbage[m: zc is input to delayshot (oneshot with another delay timer)
10:51 PM Tom_L: https://www.mouser.com/datasheet/2/149/fairchild%20semiconductor_moc3031m-544476.pdf
10:52 PM Tom_L: i used something similar to that
10:52 PM boostedcabbage[m: i might have a variation of that
10:53 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/toaster_oven/control_sch.png
10:53 PM Tom_L: lower right corner
10:54 PM boostedcabbage[m: fun
10:54 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/toaster_oven/blinktest1.jpg
10:54 PM Tom_L: i dunno how well it would do with pwm
10:58 PM roycroft: i just watched episode 2 of "wednesday"
10:58 PM roycroft: it's going to be hard to not binge watch that
10:59 PM roycroft: i thought christina ricci was the ultimate wednesday addams, but jenna ortega is much better
11:00 PM boostedcabbage[m: i watched a few and forgot about it. was fun though. should rewatch
11:06 PM roycroft: i haven't seen the wednesday dance yet
11:06 PM roycroft: i'm told it is worth waiting for
11:28 PM boostedcabbage[m: i just scaled my lincurve x range by 1000 and things are much more sane
11:29 PM boostedcabbage[m: nothing like being off by a factor of 100x or 1000x
11:49 PM serp2 is now known as serp
