12:09 AM CaptHindsight: jym: what is it with you folks in CA? https://www.huffingtonpost.com/entry/doorbell-licker-caught-on-camera-salinas_us_5c34ea73e4b0116c11f0f0fb
12:15 AM fragalot: why do drugs when you could be driving a prius. https://imgur.com/gallery/Ep3e9Lt

12:19 AM fragalot: so that's why the saturn V isn't being used anymore

02:34 AM russian_troll: selroc: Today's Log http://www.isaeff.net/logs/%23linuxcnc/2019-01-09.html
02:43 AM Deejay: moin
03:01 AM veek: gloops, hey check this out - how would you machine that tube and what about the focus/could I use a micrometer instead - Insize 3202 - it has graduations of 0.01mm but the scope needs 0.1mm/rotation : http://www.funsci.com/fun3_en/ucomp1/ucomp1.htm https://www.opto.de/media/opto_catalog_microscope_accessories.pdf
04:51 AM jthornton: morning
04:53 AM XXCoder: hey
04:53 AM XXCoder: you remember guy i talked that was drinking?
04:53 AM XXCoder: his stuff is gone, so either he now puts em away, or he was fired
04:54 AM XXCoder: we are looking for weekend mill so im guessing bye bye
05:19 AM Tom_L: 28°F
05:20 AM XXCoder: yo
05:23 AM XXCoder: heys'
05:35 AM jthornton: hmm I forgot lol
05:36 AM Sabotend_ is now known as Sabotender
05:41 AM jthornton: 39°F
05:42 AM XXCoder: jthornton: did you see what i said above?
05:43 AM gloops: hmm 10 degree v bits arrived next day - but i think the chances of carving wood with these is virtually 0 lol
05:44 AM gloops: 30 degree look doable though
05:44 AM jthornton: yea but I forgot about that guy
05:45 AM XXCoder: ahh ok lol
05:46 AM XXCoder: anyway if he is indeed gone its likely due to him drinking on job
05:46 AM XXCoder: you were surpised he was kept on so long but its only so much company will accept before "fine that guy is gone"
05:47 AM jthornton: yea, that's sad that someone can't go without drinking while working
06:31 AM elmo40: roycroft, mothballing nuclear does not make sense to me. it is, arguably, a clean energy. (if you ignore the startup costs... LoL )
06:32 AM elmo40: China is going more nuclear. also a lot of solar and wind, but that is still only single digit power producers.
06:33 AM elmo40: to get the same output as nuclear you need something like 1,500 hectares of windmills, at full wind speed, 24/7 !
06:35 AM XXCoder: elmo40: and LONG storage for spent stuff
06:35 AM XXCoder: i dont know why many pro-nuclears ignore that part
06:53 AM XXCoder: wow interesting https://grid.space/kiri
06:53 AM XXCoder: fsm, laser and milling
09:39 AM flyback is now known as cisco
09:39 AM cisco is now known as flyback
11:32 AM fragalot: hi
11:43 AM renesis: ping
11:44 AM renesis: cant change nick when in ident only chan, thats not very convenient, yo
11:45 AM fragalot: llol
11:56 AM jym: renesis: use an irc client where you can login into a network twice
11:59 AM renesis: ?
11:59 AM renesis: pretty sure i can log in as many times as i want
11:59 AM renesis: im on like three networks right now
12:00 PM renesis: im just not sure how that helps
12:01 PM renesis: if youre client logs in, and youre client is ghosted because of a disconnect, you end up with an alt nick, if your client is setup to autojoin, you in a channel with an unidentified nick
12:01 PM renesis: if you go to change your nick and identify, you cant because silenced in a channel, so you have to part, change nick and ident, then rejoin. not convenient
12:01 PM renesis: im not going to run an ident script that handles all of autojoin
12:02 PM renesis: the problem is freenode, i decided.
12:03 PM gregcnc: i thought you could ident more than one nick
12:04 PM jym: gregcnc: You CAN have multiple nicks associated to one account, example...
12:05 PM jym is now known as Jymmmmmm
12:06 PM Jymmmmmm: or
12:06 PM Jymmmmmm is now known as Red70sShow
12:06 PM Red70sShow: gregcnc: <--- Dumbass
12:06 PM Red70sShow is now known as Jymmm
12:06 PM Jymmm: =)
12:06 PM gregcnc: lol
12:07 PM renesis: gregcnc: im annoyed enough i have to ident at all
12:07 PM Jymmm: renesis: gregcnc https://freenode.net/kb/answer/registration
12:07 PM renesis: clearly the answer is #linuxcnc moves to efnet
12:08 PM gregcnc: sure, but the pleasure of listening to Jymmm makes it worthwile
12:08 PM Jymmm: renesis: Why? you can autologin
12:08 PM renesis: this is all too complicated for irc
12:08 PM renesis: my client is setup how i want
12:08 PM renesis: change is bad
12:08 PM Jymmm: renesis: Chenge is never bad, just unknown
12:09 PM renesis: no this does not apply to my irc client
12:09 PM renesis: tho i changed from tmux to screen and thats going okay
12:09 PM renesis: wait no, screen to tmux
12:09 PM Jymmm: screen isn't a irc client
12:09 PM Rab: It is if you can type fast enough.
12:09 PM renesis: right im saying maybe your statement applies to terminal windowing
12:10 PM renesis: but not to irc clients
12:10 PM Jymmm: Rab: I USED to be able to do that, but all encrypted now =)
12:10 PM Rab: Jymmm, very good.
12:11 PM Jymmm: Rab: telnet port 6667 and away we go. VERY confusing trying to irc when in multiple channels at once =)
12:11 PM renesis: ivan drago still uses bx
12:14 PM Jymmm: I like weechat
12:15 PM Rab: Hmm, no #linuxcnc on efnet.
12:15 PM Jymmm: https://weechat.org/about/screenshots/
12:15 PM renesis: actually ya ive considered switching to weechat for years
12:15 PM renesis: but looks like i dont care so much
12:16 PM Jymmm: renesis: You can use screen+weechat to login from anywere fwiw
12:17 PM jthornton: step # 1.259 finish painting the bathroom... check
12:17 PM jthornton: step # 1,300 wait for the paint to dry... pending
12:17 PM renesis: tmux + irssi does same
12:18 PM Jymmm: https://gist.github.com/timani/92a480ad6f7cbe66534e
12:18 PM renesis: i did screen + irssi for iunno, decade+
12:18 PM Jymmm: I like the windowing of weechat
12:19 PM Rab: jthornton, I must wonder about the intervening 1,298.741 steps.
12:20 PM jthornton: been putzing with this project for far too long lol
12:20 PM renesis: is like gcode, you just make the line numbers up
12:31 PM renesis: so do N words have to be in order?
12:32 PM renesis: like, only increasing
12:32 PM renesis: like, can you do N10, N30, N20 without things flipping out
12:34 PM renesis: https://www.tormach.com/g-code-formatting-reference/
12:34 PM renesis: tormach says gcode dgaf
12:37 PM mozmck: The line numbers are ignored, and I just leave them out and turn on line numbering in my editor - much more useful IMHO
12:38 PM renesis: right i normally leave em out or gap them by 10, no need to repeat or out of order so never done it
12:45 PM JT-Shop: line numbers are just comments and not used for anything
12:50 PM fragalot: always nice when you have to go around the entire neighbourhood chasing down packages that have been left at random peple's houses >.>
12:51 PM fragalot: "you weren't home, so we dropped it off 9 houses down the road"
12:59 PM Jymmm: fragalot: IS that the gingerbread house?
01:01 PM fragalot: :P
01:01 PM renesis: jt-shop: theyre used for jumps, no?
01:03 PM renesis: oh, linuxcnc uses o words
01:16 PM Jymmm: Damn, I'd LOVE to be able to engrave like this... https://www.youtube.com/watch?v=u2mWvozSdvE
01:16 PM Tom_L: funny cause o words are comments in other controls, not subs
01:17 PM renesis: i dont think theyre comments, they just dont seem to matter with file based gcode scripts
01:18 PM renesis: i think on the haas machines i used, it basically referenced all code by owords, so you wouldnt be able to pull up code without it
01:20 PM Tom_L: some fanuc controls use o words for comments
01:22 PM phaxx: that hammer is classy af
01:22 PM roycroft: you can't do that kind of work on your own, jymmm - you need a helper cat
01:30 PM renesis: helper cat is exhausted at end
01:30 PM mozmck: I've done engraving like that on mother of pearl - would love to do it on metal like that!
02:06 PM JT-Shop: renesis: we don't have jump or goto
02:45 PM gloops: i got some 10 degree v bits arrive today, i dont have much faith in them being able to v carve wood
02:45 PM gloops: .1mm tip
02:46 PM * Deejay uses them for milling pcbs
02:46 PM renesis: spin fast, cut shallow, start some coffee
02:46 PM renesis: yeah
02:47 PM gloops: Deejay what depth of cut? feed etc?
02:47 PM Jymmm: roycroft: The only kitty kat in this area is 600 pounds
02:47 PM gloops: the tips are like fish bones, i think these will quickly snap
02:47 PM Deejay: pcb has 0,035mm copper :D
02:47 PM gloops: i need 2mm deep at least
02:47 PM renesis: its deeper than that, no?
02:48 PM Deejay: i think thats not comparable to wood ;)
02:48 PM renesis: yeah
02:48 PM renesis: i would go like .005" deep, 10 krpm, and maybe 10 ipm
02:48 PM gloops: ill try 24k spindle, 12ipm maybe .5mm cut
02:49 PM renesis: how many cutters do you have?
02:49 PM gloops: 10 - theyre only like 50 pence each
02:49 PM renesis: would maybe start bit shallower
02:49 PM renesis: oh, shrug
02:49 PM Deejay: quality, eh? ;)
02:50 PM gloops: hmm maybe yeah, i could sacrifice 1 st tool, try .2mm then .3, .4 - until it snaps
02:50 PM renesis: your numbers dont seem crazy unless its super hard wood
02:50 PM gloops: i wont get chance till the weekend anyway now
02:51 PM gloops: Deejay sure..these are the best - cuts any material, doesnt wear, unbreakable etc
02:52 PM Deejay: hehe
02:52 PM renesis: ive done raster cuts in wood around those numbers, but i think they were 30 deg
02:52 PM Deejay: made from chinesium
02:53 PM gloops: https://www.ebay.co.uk/itm/10X-10-degree-0-1mm-engraving-drill-bit-CNC-router-tool-V-shaped-alloy-PCB-board/352505289911?
02:53 PM gloops: i got some 30s as well, 30 degree does look doable
02:53 PM renesis: alloy?
02:54 PM Deejay: hmm, i think i have some of them, too
02:55 PM gloops: hmm what does it mean - alloy? its says carbide on the description, they are very shiny
02:55 PM renesis: oh, who knows then
02:56 PM gloops: anyway, i guess theyll snap to a point they can hold - still be 10 degree lol
02:59 PM renesis: yeah for PCB, w/ 30deg, i would use them for .008" space/trace stuff, after breaking for .012" space/trace
03:00 PM fragalot: gloops: you may want to have an air blast to clear the chips going that deep in a single pass on wood
03:01 PM gloops: .5mm?
03:01 PM fragalot: it's a 10° tool, those are like needles
03:01 PM gloops: i can put some vaccum to it, not got any blowing set up
03:02 PM fragalot: doubt that'd do anything
03:02 PM * Deejay vacuums all his wood milling
03:02 PM Deejay: works fine. do not want all the dust in here
03:02 PM gloops: its only an experiment really, it has to be doable at a certain speed or its pointless
03:06 PM Deejay: gn8
03:06 PM gloops: night
03:12 PM fragalot: this is actually quite neat. https://openjscad.org/
03:14 PM gloops: looks like the inner shape would come out of the holes though?
03:15 PM fragalot: it's just their logo
03:15 PM fragalot: but it's openscad,.. without having to install openscad.
03:29 PM Jymmm: Ok, I'm impressed in multiple ways here... https://www.youtube.com/watch?v=LNGSNqz7-rs
03:30 PM Jymmm: even his drill guide
03:32 PM Wolf_: grr wtf cant get rt kernel to work on my itx box
03:32 PM gregcnc: first time i'v ever reverse the drill to remove the bit?
03:35 PM Wolf_: loaded the rt kernel and reboot, get a kernel panic...
03:38 PM Wolf_: JT-Shop, any ideas?
03:43 PM Jymmm: gregcnc: Yeah, I noticed that too,
03:44 PM Jymmm: gregcnc: GREAT project if you just have old slabs of wood laying around
03:45 PM gregcnc: yeah most designs like that are layers of MDF
03:46 PM XXCoder: it could be made by laser and cross sections im sure
03:46 PM XXCoder: or router
03:48 PM JT-Shop: which guide did you use to build the rt preempt kernel and how old is the motherboard?
03:57 PM Jymmm: XXCoder: not as pretty though
03:57 PM XXCoder: probabloy not no
03:57 PM XXCoder: but same time if paint is planned it matters less. i guess it depends on what person want
04:01 PM Wolf_: JT-Shop your guide for mint 19, mobo is a j1900 cpu https://www.newegg.com/Product/Product.aspx?Item=N82E16813157494
04:02 PM jthornton: Wolf_: I'd try debian 9 http://gnipsel.com/linuxcnc/uspace/debian9-rt.html
04:02 PM jthornton: I have a j1900 but IIRC it's running Ubuntu 10.04
04:04 PM Wolf_: seems to be a issue with the inird.img-4.19.1-rt3 being too large
04:08 PM Wolf_: found this https://unix.stackexchange.com/questions/270390/how-to-reduce-the-size-of-the-initrd-when-compiling-your-kernel but I dont really know what i'm doing, so not sure how to implement it
04:17 PM ziper: andypugh, I did it
04:17 PM ziper: not just the nichols but the hardinge too
04:20 PM andypugh: did what?
04:20 PM ziper: bought them
04:21 PM andypugh: Ah, right.
04:21 PM andypugh: Vague memories return
04:21 PM ziper: only problem is it was a production shop
04:21 PM ziper: so some of them are set up a little weird
04:22 PM ziper: andypugh, by the way, I liked the trick with the conical block
04:23 PM andypugh: So, how much did you pay, if that’s not an impertinent question?
04:24 PM andypugh: http://www.lathes.co.uk/nichols/
04:28 PM ziper: 100 per machine
04:29 PM andypugh: so, they were free then? (less than scrap value)
04:30 PM gregcnc: 100USD for a hardinge lathe?
04:33 PM ziper: gregcnc, horizontal mill
04:34 PM skunkworks: Rab: yes - some experimentin I am doing
04:34 PM skunkworks: http://electronicsam.com/images/greenmachine/20190104_210312.jpg
04:34 PM skunkworks: btw - you cannot rigid tap at 2000rpm on our mill... It tried though...
04:35 PM jthornton: Wolf_: my initrd.img-4.19.1-rt3 seems to be no bigger than the stock img https://paste.ubuntu.com/p/mMMKMHmJNF/
04:37 PM jthornton: skunkworks: has all the fun
04:37 PM Wolf_: mine is 10x the generic, in /boot 595.3mb vs 59.5mb on the generic
04:37 PM jthornton: yea mine is 10x the generic
04:38 PM ziper: well, about twice scrap price by my estimate
04:38 PM jthornton: you should use debian 9 instructions it's only 18.9 Mb
04:39 PM Wolf_: but I want mint lol
04:39 PM jthornton: change motherboards lol
04:39 PM jthornton: my mods to debian make it almost as nice as mint
04:40 PM gregcnc: Ziper one of the small ones I guess BB4 or something?
04:40 PM Wolf_: worst part is the kernel build took over 5hrs on that box =/
04:41 PM jthornton: follow this guide and you'll be up and running in no time http://gnipsel.com/linuxcnc/uspace/debian9-rt.html
04:42 PM ziper: gregcnc, its a bit bigger than that
04:42 PM ziper: the nichols is pretty big
04:42 PM Wolf_: going to give "make INSTALL_MOD_STRIP=1 modules_install" a shot and see what happens
04:42 PM jthornton: let me know what you get, if it works I'll update my pages
04:43 PM Rab: skunkworks, very nice. No breakouts on the two hidden corners? ;)
04:45 PM ziper: sounds like the vertical heads are pretty rare?
04:51 PM gregcnc: ziper probably, the mills aren't very common. i'd like to have a decent TM/UM
04:52 PM ziper: that looks like the one I have
04:53 PM ziper: without the head
04:54 PM ziper: how feasible is it to make up a head to fit?
04:55 PM gregcnc: here's one local with a bridgeport head on it, https://chicago.craigslist.org/nwc/tls/d/fox-river-grove-bridgeport-hardinge/6784446574.html
04:56 PM Wolf_: well, thats impressive, i killed it to the point that it locks up the bios now lmao
04:59 PM ziper: yes that looks very nice
05:16 PM jthornton: Wolf_: you mean you can't even get to the bios on bootup?
05:17 PM Wolf_: it booting but slow as dirt
05:17 PM jthornton: that don't sound good
05:30 PM Wolf_: going to give deb 9 a shot
05:56 PM skunkworks: Rab: no.
05:57 PM skunkworks: that is even taking a few thousands off to make it round after the fact...
05:57 PM skunkworks: turning on centers without a dog... Few light cuts
05:57 PM skunkworks: https://www.youtube.com/watch?v=CKGEgshU-C8
06:15 PM andypugh: skunkworks: There are actual drive centres for that
07:19 PM norias: vernier calipers are still relatively expensive
07:20 PM andypugh: Yes, I think that at the moment an actual vernier is harder to make than a digital caliper. And there is no reason to prefer the mechanical version.
07:20 PM norias: I still use mine often. I have a 12" set.
07:21 PM norias: I have 6" digital and 12" vernier.
07:21 PM norias: eh
07:21 PM andypugh: I find my 4” digital really handy
07:21 PM norias: I kinda do prefer the vernier, often. I'd buy a 6" if I was going to be machining daily.
07:22 PM andypugh: And also, the 300mm one. That’s really useful
07:22 PM andypugh: For machining the 4” is good
07:22 PM norias: depends on the machining
07:22 PM andypugh: And on a lathe, think about the left-handed ones…
07:23 PM norias: last place i was at, 50" was a normal diameter
07:23 PM norias: of course, we used micrometers to measure that
07:23 PM andypugh: that’s a job for a Pi tape
07:23 PM gregcnc: oh, how many actually make left hand calipers?
07:23 PM norias: we pi taped for rough and mic'd for final inspection
07:24 PM andypugh: norias: they make vernier pi tapes, 3.14x more accurate than a caliper
07:24 PM norias: yeah, that's what we had
07:24 PM norias: did .001" supposedly
07:25 PM norias: but, again, we mic'd for final dimensions
07:25 PM andypugh: A vernier pi tape should be nearly as good as the caliper. Possibly better.
07:25 PM norias: uh, sure, but we're talking about micrometers
07:26 PM andypugh: (My dad used to work for a company that made 23m gears. That was pi-tape all the way.
07:26 PM andypugh: Sorry, I meant to say caliper v Pi tape
07:28 PM andypugh: vernier is good to 0.001”, so vernier pi tape is good to 0.000318. Who wins>
07:29 PM gregcnc: how difficult is it to get wrapped around the part properly?
07:31 PM andypugh: Well, you need a bunch of apprentices with a 23m gear….
07:40 PM Tom_itx is now known as Tom_L
07:40 PM ziper: norias, why do you prefer the vernier?
07:40 PM norias: no batteries, no rack
07:40 PM norias: you choose your level of precision
07:40 PM ziper: what about dial?
07:40 PM norias: dial's have racks
07:40 PM andypugh: But: The digital ones have extra tricks.
07:40 PM norias: there's basically nothing that can fail on a vernier
07:40 PM norias: they are faily bullet proof
07:40 PM norias: fairly
07:40 PM andypugh: Making a part to metric on an imperial lathe? Measure the mating part, or dial in the dimension. Zero the caliper, change the units. Now you know how much to take off in lathe-native units
07:40 PM norias: i only have the 6" digitals because they were a required purchase during my apprenticeship
07:41 PM gregcnc: I used to like vernier, but no longer, too slow
07:41 PM andypugh: Mesuring hole centres? (or stud centres)? Measue one hole or stud, zero the caliper, read centres directly, with no maths.
07:42 PM norias: everyone has their preferences
07:42 PM ziper: neat
07:42 PM andypugh: Looks odd? Change units
07:43 PM gregcnc: I need a coolant proof caliper. My lathe drips coolant right onto the part I'm trying to measure
07:43 PM andypugh: Not sure how obvious the hole-centre one is, I thought it was, sent it to a magazine, got a free sub. 2 years ago.
07:44 PM gregcnc: not very, I was like Oh duh, I do it all the time in my head
07:44 PM gregcnc: all metric so not difficult
07:44 PM andypugh: I have a rack-based coolant-proof digital, but hate it as it isn’t absolute and times-out in 30 seconds.
07:45 PM ziper: what do you mean isn't absolute? you have to zero it every time?
07:46 PM andypugh: Yes, when it goes to sleep have to puch it back to closed and re-zero
07:46 PM andypugh: Seems to be rack-ancoder
07:46 PM andypugh: (encoder)
07:47 PM andypugh: I haven’t yet tried a proper coolant-prrof digital. All mine go screwy for days if they get a drip of coolant.
07:48 PM gregcnc: not exactly cheap
07:51 PM andypugh: Talking of calipers, some are now so cheap you can take a hackwaw to them with a clear conscience. : https://www.thingiverse.com/thing:3238845
07:51 PM norias: 3 phase brushless dc motor?
07:52 PM andypugh: (held on by magnets)
07:52 PM norias: uh... is that a thing?
07:52 PM gregcnc: Don't they come that way for quills already?
07:52 PM andypugh: gregcnc: Yes. But mine needed no machining of the lathe and cost < $10
07:53 PM andypugh: norias: I have never seen a brushless motor that _wasn’t_ three phase
07:53 PM gregcnc: sure you have
07:53 PM gregcnc: muffin fan
07:54 PM norias: there's a phase in DC power?
07:54 PM gregcnc: electronically commutated DC motor
07:54 PM pcw_home: stepmotors are brushless 50 pole motors...
07:54 PM andypugh: Well, technically every stepper is a 2-phase brushless motor. But I was trying to get the right balance between helpful and pedantic :)
07:55 PM pcw_home: some variable reluctance motors also
07:55 PM gregcnc: brushless DC is common today, less so 20 years ago
07:56 PM andypugh: norias: Brushless DC motors are, actually, not DC.
07:56 PM norias: oh?
07:56 PM gregcnc: trapezoidal commutation VS sinusoidal
07:57 PM gregcnc: do you have questions about BLDC?
07:57 PM norias: reading right now
07:57 PM andypugh: gregcnc: Accurate, but not helpful…
07:57 PM gregcnc: trivial
07:58 PM gregcnc: i suppose it depends if you're being very picky with the application
07:58 PM andypugh: norias: If you consider a classical DC motor, the commutaror and brushes arrange matters such that the power supply to the motor is DC but the current through the rotor is 2-phase AC. Got that?
07:59 PM norias: yeah
08:00 PM andypugh: So, a brushless DC motor has a 3-phase stator independently commutated, but is otherwise constructed like a clasical DC motor
08:01 PM andypugh: There are sensors in the motor that tell the controller where the rotor is, and the field coils are energised accordingly.
08:02 PM andypugh: At this point it is useful to step back to the stepper
08:02 PM andypugh: You energise the 2 phases of a stepper in a sequence and the rotor chases rhe stator
08:03 PM andypugh: With a brushless motor it’s much the same, except that the stator knows where the rotor is, and runs away…
08:05 PM andypugh: So the stator magnetic field is always 90 degrees away from the rotor, for maximum torque and/or minimum current
08:08 PM andypugh: Stepper; rotor magnets chases stator magnetic field , generally catch it. Brushless: Stator magnetic field senses rotor magents and runs away, never ge4ts caught.
08:08 PM pcw_home: right, a step motor without feedback spends most of its time pulling radially (0 degrees) on the rotor at full current
08:10 PM andypugh: There are 5 phase stepprs too. Once you grasp the two modes of operation, those make sense too
08:11 PM pcw_home: also 3 phase stepmotors
08:11 PM andypugh: You can run a 3-phase brushless as a stepper, you can run a stepper (+ encoder) as a brushless.
08:11 PM pcw_home: Rather big steps however
08:12 PM andypugh: And “AC servos” are physically identical to “brushless DC” motos
08:14 PM andypugh: It’s common to drive a brushless motor or AC servo in “stepper mode” when searching for encoder index or motor zero to start commutation in bldc or ac servo mode
08:14 PM andypugh: norias: Still there?
08:14 PM norias: yeah
08:16 PM andypugh: You have the fortune / misfortune to talking to a manufacturer of AC servo / BLDC drives and the chap wrote the LinuxCNC driver for it.
08:17 PM andypugh: if rene_dev_ is still awake then we can assemble a genuinely world class team :-)
08:18 PM andypugh: How far down this rabbit hole do you care to venture :-)
08:19 PM andypugh: (And I still have no idea when a BLDC motor becomes an AC servo)
08:20 PM andypugh: gregcnc: Mantioned Trapezoidal and Sinusoidal commutation. Both work with all three motors mentioned so far.
08:21 PM andypugh: Sinusoidal commutation is a close analogue to high-division microstepping of stepper motors.
08:23 PM andypugh: Here is a video of the exact same motor being commutated trapezoidally and sinusoidally. https://www.youtube.com/watch?v=47y6RgAK--8
08:24 PM andypugh: So, it starts off being what most would call BLDC then transmogrifies into an AC servo.
08:27 PM andypugh: Anyway, I hope we now have you utterly confused, as it is time for me to sleep :-)
08:32 PM `Wolf: JT-Shop, so far so good, pip wouldnt install tho
08:32 PM elmo40: i love the look of confusion ;-)
09:23 PM flyback: https://en.wikipedia.org/wiki/TI-RTOS
09:23 PM * flyback bites elmo40
09:23 PM flyback: I HATE ELMO
09:23 PM flyback: ESPICALLY IF ELMO IS A EH?-HOLE
09:23 PM flyback: CANUCK!
09:55 PM `Wolf: ugh, got the box working, mostly, cant ping the mesa =/
09:56 PM justan0theruser is now known as justanotheruser
10:32 PM skunkworks: `Wolf:why not?
10:56 PM `Wolf: cause I missed something simple lol
10:56 PM `Wolf: got it connected now
10:57 PM `Wolf: just need to figure out how to config now
