12:18 AM Jak_o_Shadows: ok. Back.
12:21 AM Jak_o_Shadows: Time to get the servo usb thing working
12:28 AM rue_shop3: thats a possability for my next project
01:05 AM Jak_o_Shadows: and of course the usb is not working properly
01:14 AM * rue_shop3 coughs "generic adapter"
01:36 AM Jak_o_Shadows: nah, it aint even identifying
01:59 AM rue_shop3: glad I dont have that problem
01:59 AM rue_shop3: where am I tho
02:00 AM rue_shop3: I need to start with my servo control code
02:02 AM rue_shop3: ok, as expected I have one timer going at 50Hz and the other set up for a timeout at 2.5ms
02:04 AM rue_shop3: so, timer 3 sets off timer 2
02:05 AM rue_shop3: ok, so, the first trick is to get timer 2 to run continously, and walk thru an array of values
02:05 AM rue_shop3: Jak_o_Shadows, you gonna wrestle with comms or get the pulses working?
02:06 AM rue_shop3: I'm going for pulses
02:06 AM rue_shop3: I'll give it a pl2302 for now
02:06 AM Jak_o_Shadows: Lunch atm.
02:06 AM Jak_o_Shadows: Then download the known workign usb config
02:06 AM Jak_o_Shadows: then merge me together if it works
02:09 AM rue_shop3: damn, I lost the pdf that actaully says how to program these damn things
02:10 AM rue_shop3: ok got that
02:10 AM rue_shop3: timer 2
02:11 AM rue_shop3: timer 2 has 4 channels
02:13 AM rue_shop3: • Assigns the corresponding output pin to a programmable value defined by the output
02:13 AM rue_shop3: compare mode (OCxM bits in the TIMx_CCMRx register) and the output polarity (CCxP
02:13 AM rue_shop3: bit in the TIMx_CCER register). The output pin can keep its level (OCXM=000), be set
02:13 AM rue_shop3: active (OCxM=001), be set inactive (OCxM=010) or can toggle (OCxM=011) on match.
02:13 AM rue_shop3: ok so...
02:14 AM rue_shop3: I want it to set it
02:14 AM Jak_o_Shadows: The giantic freaking reference manual?
02:14 AM rue_shop3: I call it the register manual
02:17 AM rue_shop3: ah, page 319...
02:20 AM rue_shop3: hmm
02:21 AM rue_shop3: ah 331 output compare mode
02:25 AM rue_shop3: I swear this datasheet makes my head spin more than anything else I'v read
02:30 AM rue_shop3: ok, wow
02:31 AM rue_shop3: so what I do know is that the timer can set the pin
02:31 AM rue_shop3: I can see that I want to set it up to toggle it first
02:31 AM rue_shop3: but, its midnight, and I'm kinda tired
02:31 AM Jak_o_Shadows: flipping usb.
02:33 AM rue_shop3: so, my first goal, is to set up timer2 for continious cycling, with it toggling its io pin ( channel 1 for now) every match
02:34 AM Jak_o_Shadows: That's like your led exampel ey?
02:34 AM rue_shop3: its the first thing to test,
02:34 AM rue_shop3: if I can get it to toggle the pin with the timer, I can get it to set it
02:35 AM rue_shop3: on the avr, when you ahve the timer control the pin, RESETTING the pin is non-trivial
02:35 AM rue_shop3: you have to use the timer system bu resetting it up to clear on match, and then forcing a mactch, then setting it back up to set on match
02:35 AM rue_shop3: I dont know if the stm32 is the same
02:37 AM rue_shop3: yea, falling asleep
03:00 AM Jak_o_Shadows: ok. Was something to do with the clock.
03:02 AM Jak_o_Shadows: oh, wait, nup
03:31 AM Jak_o_Shadows: ok.
03:31 AM Jak_o_Shadows: I think this is just the stm32 that disagreed with usb
03:39 AM Jak_o_Shadows: Just bought 2 stm32s
03:41 AM Jak_o_Shadows: Possibly a hardware thing.
03:41 AM Jak_o_Shadows: In that case, I'm going to dig out my usb-serial adaptoer
06:17 AM Jak_o_Shadows: rue_shop3, https://github.com/Jak-o-Shadows/stm32-PCA9685 - i have the serial control working. But no gui just yet
11:58 AM rue_bed: I'm interested in 74hc595 at 24Mhz
12:10 PM Tom_L: http://www.openplcproject.com/plcopen-editor
12:54 PM rue_shop3: Jak_o_Shadows, hmm, the idea is to use the 0xFF to stay in sync...
12:55 PM rue_shop3: thats where its nice to throw it bytewise into a state machine of some kind
12:56 PM rue_shop3: ? only 8 bit positioning?
12:57 PM rue_shop3: oh the 9685 is that pwm chip, k
12:58 PM rue_shop3: I need to think about this again
12:58 PM rue_shop3: 12 bit, over 20ms
12:59 PM rue_shop3: the workable range is 0.5 to 2.5ms
12:59 PM rue_shop3: 10 1024, 11 2048, 12 4096
12:59 PM rue_shop3: 4.883us per clock
01:00 PM rue_shop3: so the low count is 102
01:00 PM rue_shop3: the high count is 512
01:00 PM rue_shop3: so your resolution is 410 counts
01:01 PM rue_shop3: less than 9 bits
01:01 PM rue_shop3: k
01:01 PM rue_shop3: ....
01:04 PM rue_shop3: hmm
01:05 PM rue_shop3: according to this my code runs 4000 counts/ms
01:05 PM rue_shop3: low count is 2000, high count is 10000, so my resolution is 8000 counts
01:06 PM rue_shop3: so I'v only got 19.5x your resolution, huh
01:06 PM rue_shop3: but on the avr...
01:08 PM rue_shop3: well, +- the conflict its either 24000 counts or 31000 counts
01:09 PM rue_shop3: so the avr wins so far on resolution
01:09 PM rue_shop3: have to work on that
01:10 PM rue_shop3: hmm, well, as long as there is no jitter I suppose the resolution dosn't matter
01:11 PM rue_shop3: its the jitter in prycon that made me pandemic
01:13 PM rue_shop3: ok, my goals today are to redo the outside work table and etch 10 tiny13 boards
01:22 PM Tom_L: looks like rue_shop3's awake
01:48 PM Tom_L: oh it's fun to get packages
02:38 PM Anniepoo: 8cD packages!
02:38 PM Anniepoo: love packages
02:40 PM Anniepoo: robot-y stuff in Amaon boxes, jameco, mouser, crazy chinese panlishop
03:04 PM synja: i always love mouser deliveries
03:04 PM synja: they're the most fun!
03:37 PM rue_shop3: what did you get?
04:44 PM rue_shop3: so, apparently the last time I etched a board was 2014
04:44 PM rue_shop3: see if I can get everyting going agian
04:49 PM Tom_L: wow
04:49 PM Tom_L: that means it's been longer than that for me
05:00 PM rue_shop3: ok heat, bubbles, see how that goes
05:00 PM rue_shop3: next
05:00 PM rue_shop3: there is a plotter on the top of this table, somewhere
05:39 PM rue_shop3: I think there is more stuff under the plotter than there was on it
05:46 PM rue_shop3: ok
05:46 PM rue_shop3: just about ready for a paper test
05:55 PM rue_shop3: almost have a pen working
05:57 PM rue_shop3: ok, will the pcb station boot?
05:57 PM rue_shop3: ...
05:58 PM * theBear says yes
05:58 PM rue_shop3: ..... no
05:58 PM * theBear approves this cold b00t
05:58 PM * theBear approves it, dammit !
05:58 PM rue_shop3: something is wrong with its power supply....
05:59 PM rue_shop3: it flashes and goes out
05:59 PM rue_shop3: hmm
05:59 PM Tom_L: rue_shop3
05:59 PM rue_shop3: its STILL faster than sending off from china!
05:59 PM theBear: something is wrong with YOUR power supply, buddeh ! (i'm not your buddeh, fwiend ! (i'm not your friend, guy !))
06:00 PM Tom_L: if a breaker is rated for 5A @ 120v is it's rating still 5A at say 24v?
06:00 PM theBear: hehe, nothing like a joke pointing out the subtle differences between different people from different places and backgrounds to really make people feel that brotherhood glow on their inside
06:00 PM rue_shop3: ugh, getting it out of there will be a challange
06:00 PM theBear: least, that's what i always assumed <grin>
06:00 PM rue_shop3: Tom_L magnetic?
06:01 PM Tom_L: Schneider Electric #60103 DIN rail mount 5 amp circuit breaker.Specs:Amps 5Number of Poles 1
06:01 PM Tom_L: 60-125vdc
06:02 PM theBear: Tom_L, generally should be .... all the maths from ohms law to rules you need to make a thumbs-up fist to remember suggest it's all about current however it measured/triggered, only gotcha is the other direction, things like 32v car fuses will tend to often/always not open a big enough gap for maybe mains or 1kV or whatever voltages not to skip
06:02 PM Tom_L: so what happens below 60v?
06:02 PM theBear: also remember din style mains breakers tend to have much more detailed ratings if you look at the full datasheet, time@%-rated-trip-current kinda graphs
06:02 PM rue_shop3: the funny part is that this thing is always off
06:04 PM theBear: Tom_L, think of a clamp meter, or a wire (v=r*i, p=v*i, all conductors are really tiny resistors deep down), however a fuse senses/gets blow-ed, it is unaware of the voltage that made it happen (unless it's some fancy electronic insides thing maybe that needs >= X volts somehwere to make the brain part work
06:04 PM Tom_L: i suppose it would be ok since the motor is a 90v dc motor
06:05 PM Tom_L: rue_shop3, do you know how much current those sherline motors draw?
06:05 PM rue_shop3: no
06:05 PM rue_shop3: 36W aren't they?
06:06 PM Tom_L: i've been using 3 & 4A fuses and been ok until i started tuning the pid and it was chattering
06:06 PM Tom_L: it didn't like that much
06:07 PM rue_shop3: no, your unidirectional idea is better for that
06:07 PM rue_shop3: esp cause you have a slow relay doing direction
06:08 PM Tom_L: it wasn't the bidirectional orient that was the problem i don't think
06:08 PM rue_shop3: you cant do positioning like that with a controller that uses a relay for direction
06:08 PM Tom_L: i had some pretty severe numbers in the pid
06:08 PM Tom_L: it picks a direction and sticks with it
06:08 PM rue_shop3: stupid computer uses a nonstandard power supply...
06:08 PM Tom_L: once it knows the shortest path
06:08 PM Tom_L: that part works ok
06:09 PM theBear: it was the round-trip express that caused the issues ? (bi-dir orient ? not even a near-smile ? one edge of yer lips just twitching in acknowledgement ? <grin>)
06:09 PM Tom_L: i find the index mark and i can switch the relay with it
06:10 PM Tom_L: http://linuxcnc.org/docs/2.7/html/man/man9/orient.9.html
06:10 PM Tom_L: theBear so you can catch up
06:11 PM rue_shop3: !!@%@$%&@$#@$%! this wont be easy to fix
06:11 PM Tom_L: i think i'm gonna go back out and see how many fuses i can pop
06:11 PM Tom_L: rue_shop3, wtf did you do now?
06:12 PM theBear: you know anything interesting only makes me get more distracted and behind <grin> even assuming i got many many years left to be distracted or catch things during, i'm pretty much resigned to the idea that any catching up ahead of me will be +2steps/-1+3/4 steps kinda leapfrog false-progress ;-)
06:27 PM rue_shop3: ok, piece of test copper is in the tank
06:34 PM theBear: test copper - check !
06:42 PM rue_shop3: ok, that wasn't easy
06:42 PM rue_shop3: copper is still all there, so, I think this is just blue water
06:43 PM rue_shop3: ok, put this power supply back togethor and see what I win
06:44 PM theBear: heh, in these situations it probly worth using the good stuff, you know, the not-blue water supply <grin>
06:45 PM rue_shop3: I usually have to mix up a new batch every time I etch
06:45 PM rue_shop3: I thought, I was out... but I seem to have a cold
06:46 PM theBear: maybe you were out, now you're awake again, and you had a cold for both of those :)
06:52 PM rue_shop3: seems to work
06:52 PM rue_shop3: stress test is
06:52 PM rue_shop3: it..
07:10 PM rue_shop3: ok, took a bit to get the plotter spooler going again
07:10 PM rue_shop3: the pcb workstation is holding in
07:10 PM rue_shop3: theBear, is it normal to never leave home?
07:11 PM rue_shop3: I'm getting closer
07:12 PM Tom_L: well the pid isn't getting worse
07:12 PM theBear: umm, you mean, oh you, like, physically, not living with parent(s) indefinately (err, "failure to launch" syndrome i think...) ummm, for guys like us i think so
07:13 PM theBear: rue_shop3, ironically, often those times we can't seem to reach escape-velocity when we planned to go somewhere or gotta do something elsewhere, are the most productive in recent years, least they are in my house
07:13 PM rue_shop3: the clad in the etching tank is still ok
07:14 PM rue_shop3: no I mean like never going anywhere unless your working
07:14 PM Tom_L: only if i could...
07:14 PM rue_shop3: I have a truck, I could go anywhere, I have no interest in leaving
07:15 PM Tom_L: go visit theBear again
07:15 PM rue_shop3: I'm more likley to drop in and see you
07:16 PM rue_shop3: and just as likley to go see someone in china, but I dont know anyone there
07:16 PM Tom_L: it's not the place you likely envision
07:16 PM rue_shop3: terrible air and multifloor stores wall to wall with components
07:17 PM Tom_L: maybe in china
07:18 PM Tom_L: although there are a couple places that could occupy you for a day or so
07:18 PM Tom_L: just not like it used to be
07:18 PM Tom_L: anywhere
07:18 PM theBear: pfft, in communist red-state bearLandia, you occupy couple places for a day or so !
07:18 PM theBear: heh, see what i did there ? with the words and the order they came in ? brilliant !
07:23 PM synja: when i place my phone on top of my crappy keyboard, there are occasional ghost keys from the radiation
07:25 PM theBear: hmmm, if i was you, i woulda err, not-do-that with my phone, unless of course i enjoy the suspense of wondering what it will ghost next :)
07:26 PM synja: that's not nearly the worst part of using this keyboard
07:26 PM synja: it's a cheap $25 dollar rf keyboard mouse setup
07:26 PM synja: no wonder right
07:28 PM rue_shop3: ok, cant I find the mixing instructions
07:31 PM theBear: heh, friend got one of them (for a few months his lappy had a dead screen therefore lived in the lounge near the big tv) ... it's fine up close, but right around the couch/comfortable sitting+viewing distance from the tv/screen, it starts to lose reception, not all the time, but JUST often enough to drive you mental by making the mouse skip around or ignoring a click or modifier-key midway thru doing something, in ways that just eff you up
07:31 PM theBear: completely (that whole remotely-recent-windows-version business doesn't help either, all sorts of crazy stuff happens with odd modifier keys, god-forbid you accidentally touch a touchpad or screen with more than a single fingertip ! noone really seems to know what is supposed to happen when you do, but it certainly surprises teh heck outta me every damed time !
07:33 PM synja: lol
07:35 PM rue_shop3: ok, started new batch of ammonium persulfate
07:36 PM theBear: you going for a record fer most different etch chemistries used in one morning over there bud ?
07:37 PM theBear: bonus points if you can do a batch that ends up one each of the primary or basic rainbow colours by the time it's done etching
07:38 PM rue_shop3: I made some of the self-redoing etchant, but not enough
07:39 PM rue_shop3: so I'm getting closer
07:40 PM rue_shop3: think any of my resist pens work?
07:40 PM rue_shop3: ;) at this rate, I'm doomed
07:43 PM rue_shop3: ok, this is the funkey peice of clad, big lump in it
07:56 PM rue_shop3: ok first board in
08:11 PM veverak: https://scontent-frt3-1.xx.fbcdn.net/v/t35.0-12/21054995_1679877812023597_8780084353709022198_o.jpg?oh=bf79e58062f5ccecf1920e0132a97916&oe=59A48208
08:11 PM veverak: https://scontent-frt3-1.xx.fbcdn.net/v/t35.0-12/21083083_1679877708690274_3691785698606596564_o.jpg?oh=e418e2de569502e71790771236932f62&oe=59A49A3E
08:11 PM veverak: look what I've found
08:15 PM veverak: so, which GPS module to use? :)
08:30 PM Jak_o_Shadows: GPS modules are annoyingly somewhat expensive
08:30 PM Jak_o_Shadows: also, yeah, was thinking about how to get it to detect the sync thing
08:31 PM SpeedEvil: $10ish?
08:31 PM SpeedEvil: how is that expensive
08:31 PM Jak_o_Shadows: I couldn't find one for less than 20 last I looked
08:31 PM Jak_o_Shadows: huh.
08:31 PM Jak_o_Shadows: first aliexpress result, US 7
09:06 PM rue_shop3: getting there, etching is going a bit slow
09:07 PM Tom_shop: light a fire under it
09:08 PM theBear: then keep it burning and move it under your underside, might get yer out that door before the sun goes down again <wink>
09:25 PM rue_shop3: ok, last of 14 boards printed
09:25 PM rue_shop3: etching 3 at a time
09:26 PM rue_shop3: the newest pens are marked 2014, but even the 2010 ones seemed ok
09:26 PM Tom_L: oh just spit on em a bit, they'll come back to life
09:27 PM Tom_L: drip some iso on em
09:27 PM rue_shop3: hah
09:27 PM rue_shop3: most of them retire from worn out tips
09:27 PM Tom_L: rue_shop3
09:27 PM rue_shop3: a .2" line isn't good for much
09:27 PM Tom_L: i've got it working to a point that motion.orient-is-oriented goes true and motion.spindle-locked goes true
09:28 PM Tom_L: this little thing will never orient right because it's a cheap motor etc but the mechanics of it are in place and working
09:28 PM Tom_L: so with the motion.spindle-locked ouput you can feed that to the tool changer code
09:28 PM Tom_L: which has several movement steps to it
09:30 PM Tom_L: now for a bowl of ice cream.
09:31 PM rue_shop3: oooo, if I play my cards right, I can use the cnc to drill these
09:31 PM * Tom_L deals rue_shop3 a loaded deck
09:32 PM rue_shop3: Tom_L, your motor drver is wrong, you need an all-solid-state one
09:32 PM Anniepoo: ?? what're yall making?
09:32 PM Tom_L: stuff
09:32 PM Tom_L: just stuff
09:32 PM rue_shop3: Anniepoo, etching circuit boards,
09:32 PM Anniepoo: ooh stuffometry
09:32 PM rue_shop3: which I apparently havn't done since 2014
09:32 PM Anniepoo: 8cD
09:32 PM Tom_L: Anniepoo i've been working on my sherline cnc trying for a couple weeks to get spindle orientation working so the code can be used for a tool changer
09:33 PM Anniepoo: cool
09:33 PM Tom_L: and now it somewhat orients
09:33 PM rue_shop3: the etchant was dead, the print spooler didn't work, the power supply in the pcb station was dead
09:33 PM rue_shop3: and I had to rebuild the outdoor workbench
09:33 PM rue_shop3: and everything had to be unburried
09:33 PM Anniepoo: whats 'orients'?
09:34 PM Tom_L: tool holders have to be in a certain position in order to fit back in the tool rack
09:34 PM Anniepoo: ah
09:34 PM Tom_L: this turns the spindle to that position and stops
09:34 PM Anniepoo: rotationally
09:34 PM Tom_L: then the tool changer can move in and swap tools
09:34 PM Tom_L: yes
09:34 PM Anniepoo: niftoid
09:35 PM Anniepoo: we don't have a tool changer
09:35 PM Tom_L: i don't either
09:35 PM Tom_L: :)
09:36 PM Tom_L: but i
09:36 PM Tom_L: but i'm writing the code for one
09:36 PM Anniepoo: nice!
09:40 PM Tom_L: but the problem is the spindle motor isn't a servo so it kinda klunks along
09:40 PM Tom_L: but the code works never the less
09:41 PM Jak_o_Shadows: You know. I think it might be 3d printing time
09:50 PM The_Jester_: well hello you
09:52 PM rue_shop3: 14 etched, undrilled circuit boards
09:52 PM rue_shop3: too bad I dont ahve a machine I can use to drill them eh?
09:52 PM The_Jester_: use the sherline :P
09:52 PM rue_shop3: some kinda circuitboard drilling machine
09:52 PM rue_shop3: how did work go?
09:52 PM rue_shop3: no crashes?
09:53 PM The_Jester_: ^^^
09:53 PM rue_shop3: were the book cases there?
09:53 PM rue_shop3: The_Jester_, is was a venture, had to unburry the plotter, and the pcb computer didn't work (the 5vsb died)
09:53 PM rue_shop3: few things I had to fix up
09:55 PM The_Jester_: bosss didnt bother fixing the referaces to fix the queries in acess, empoyee overwrote the saved admin password for the back end up the website. shelves were there but i didnt bring the p/u usual SNAFU
09:56 PM rue_shop3: huh
09:58 PM rue_shop3: The_Jester_, yay for you getting that sodium persulfate, saved the day
09:58 PM The_Jester_: I seem to be the first one ever who wants to mount a db-25 this way
09:58 PM The_Jester_: knew it would
09:59 PM The_Jester_: sure main electronics has vanished by now
09:59 PM The_Jester_: with lees leaving
10:00 PM rue_shop3: heh
10:00 PM rue_shop3: no, I think there were 3 stuckup people who shopped there
10:01 PM The_Jester_: buting up garbage leftover television tuners
10:01 PM rue_shop3: well, I'm sure I'v had my years intake of nasty chemicals
10:02 PM Tom_L: still have your sense of smell?
10:02 PM rue_shop3: WHAT!?
10:02 PM rue_shop3: SPEAK UP!
10:02 PM The_Jester_: thats litteraly nothing unless you have a job as a glasser or body man i dont know about
10:02 PM Tom_L: from the nasty chemicals
10:02 PM Tom_L: i don't
10:03 PM rue_shop3: what did you do?
10:03 PM rue_shop3: I thought you were a machinist who sold insurance?
10:04 PM Tom_L: maybe in a previous life
10:05 PM Tom_L: ever try any ceramic bearings?
10:05 PM rue_shop3: hah no\
10:06 PM rue_shop3: too expensive even from china
10:06 PM Tom_L: i got 4 tubes of em today
10:06 PM rue_shop3: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
10:07 PM The_Jester_: Fancy
10:08 PM rue_shop3: !! too expensive to buy from china even if your just buying one
10:08 PM rue_shop3: like $32ea
10:08 PM * The_Jester_ thows up a little
10:09 PM The_Jester_: yuck
10:09 PM Tom_itx: http://www.vxb.com/16-Skates-608-2rs-Sealed-Ceramic-Bearing-8x22x7mm-p/608-2rs-16.htm
10:09 PM theBear: wtf ! for that kinda money you can order a couple hundred pc 80mm bldc fan thingers, direct from sunon, including international not-slowboat delivery, maybe get 3 in your hand for every $32 saved, then smash those open and steal the nice new maglev/ceramic bearings in there :)
10:11 PM Tom_itx: that's just a little more than a buck a piece
10:11 PM rue_shop3: ... their only half ceramic?
10:11 PM Tom_itx: the balls
10:11 PM rue_shop3: yea, but
10:12 PM theBear: speaking of skates, they got these things called umm, "Yvolution Neon Street Rollers" here now.... https://www.bigw.com.au/product/yvolution-neon-street-rollers-pink/p/WCC100000000496887/ looks pretty effing cool no ? i wanna get me someof them, hopefully i be able to work em with one mostly dead foot too, otherwise i look pretty silly, all crippled with a walkin stick and scraped elbows, lying in the street somewhere with big flashing pink led
10:12 PM theBear: wheels strapped to my shoes <grin>
10:14 PM theBear: oh i've GOT the balls... and they're traditional, and must be huge, i had growled at me a couple times over the years, but err, the point was, no ceramic here, no sir
10:15 PM Tom_itx: http://www.vxb.com/608-Full-Complement-Ceramic-8x22x7-Miniature-p/kit10943.htm
10:15 PM Tom_itx: now there's one for ya rue
10:16 PM The_Jester_: exceeds rue's $1 per project
10:17 PM Tom_L: he's been known to fudge on that a time or two
10:20 PM Jak_o_Shadows: GO TO HELL WINDOWS 10 CREATORS UPDATE
10:21 PM * rue_shop3 crosses his arms and mumbles $20
10:21 PM rue_shop3: theBear, $49!?
10:22 PM Jak_o_Shadows: I can't connect to ch340g devices
10:22 PM rue_shop3: what does the kernel say?
10:22 PM rue_shop3: oh, under windows?
10:22 PM Jak_o_Shadows: yeah. Windows.
10:22 PM rue_shop3: not an important problem
10:23 PM rue_shop3: the answer is that windows dosn't care what the chipset is, it wants to know what product you have
10:23 PM rue_shop3: and even if the chipset matches, if it thinks its a different product, it'll just refuse to do anything
10:24 PM The_Jester_: do u want the driver...
10:24 PM Jak_o_Shadows: It's not the driver. THe device descriptor fails
10:25 PM The_Jester_: *shrugs* should have fallen for the Linux meme i guess
10:25 PM Jak_o_Shadows: aye.
10:25 PM rue_shop3: Jak_o_Shadows, damn, I didn't check out your python program
10:25 PM Jak_o_Shadows: It aint that complex
10:26 PM The_Jester_: I hate win 10
10:26 PM Jak_o_Shadows: Whilst it's 3d printing, I might get the gui to work with the new protocol
10:26 PM rue_shop3: snaf, no gui
10:27 PM rue_shop3: Jak_o_Shadows, you didn't want to stick with the 16 bits eh?
10:27 PM Jak_o_Shadows: ?
10:27 PM rue_shop3: I noticed you peeled it back to 8?
10:27 PM Jak_o_Shadows: The SSC protocol is only 8?
10:27 PM The_Jester_: no gui, Rue would perfer punch tape
10:27 PM theBear: rue_shop3, umm, yeah ? i figured compared to non-cost-price skate/blade-wheel (that sized) bearings in 'em, 2 per wheel, so we talking err, 8 nice big new not-too-shitty-quality ball bearings'es, lucky to get them fer under $30 off the shelf at a skate or similar kinda shop these days... magic flashey led stuff molded INSIDE the wheels, i mean, that's some hi-tech sneak-jiggery going on there, no doubt ! bet that took those boffins years to get
10:27 PM theBear: working smoothly... and ya know, a cool logo thingy and a little strap with some handy little catch/loopey thingers included... surely it's costing me money NOT buying them for that much <wink>
10:27 PM rue_shop3: yea, the code I gave you was modified to 16
10:27 PM The_Jester_: :P
10:27 PM Jak_o_Shadows: aha. Yeah, ok, might've missed that
10:27 PM rue_shop3: cause I have to get up to 12000 for my controller
10:28 PM rue_shop3: zhanx, you hiding under the table cause those 4 peices of wood aren't done yet?
10:28 PM rue_shop3: !?
10:28 PM theBear: rue_shop3, you know our dollar always been shit except a couple months when america messed all the currencies a bit by spending all their money, and maybe half that much again, on stuff like bullets and feeding troops for a not-war they waged for several long years somewhere far from here.... it probly worth half or what yours or a euro is worth today
10:29 PM rue_shop3: :)
10:29 PM rue_shop3: our dollar is still floating up!
10:29 PM rue_shop3: I think the au and cad are almost par
10:29 PM Jak_o_Shadows: I know more is better, but... is there much need for much more than 0.5 deg resolution?
10:29 PM Jak_o_Shadows: (which is more than 8 bvits, I know)
10:30 PM rue_shop3: 12000 over 180 degrees?
10:30 PM rue_shop3: .015 degrees
10:30 PM Jak_o_Shadows: Is it expected that servbos can actulaly do that?
10:30 PM The_Jester_: must be over the servos internal resolution...
10:30 PM rue_shop3: Jak_o_Shadows, dispite my babble, whats ACTAULLY important, is that the pulse timing be STABLE
10:30 PM Jak_o_Shadows: Yeah.
10:31 PM The_Jester_: you dont like dancing servos?
10:31 PM rue_shop3: if you get 5ns jitter is the pulses, the servo will go all parkinsons
10:31 PM rue_shop3: Jak_o_Shadows, no, I just cant stand to do any less than the hardware can do
10:32 PM rue_shop3: Jak_o_Shadows, tho!, I do want to write a library with a resolution of 0.5ms that can operate 50 servos, just to see who thinks its cool and awesome
10:33 PM * rue_shop3 fidgets with his circuit boards
10:53 PM rue_house: ok, so
10:54 PM rue_house: ok I have to think
10:54 PM rue_house: the baord are etched, that was the goal
10:55 PM rue_house: I can do them as I need them
10:55 PM rue_house: its amazing how cleaning up 10% of my yard destroys the other 90%
10:55 PM Tom_L: good you didn't dig a cave house
10:56 PM Tom_L: you'd dig yourself in
11:05 PM Jak_o_Shadows: stupid z-height
11:06 PM Jak_o_Shadows: I now have a new reason to get a bed levelling probe
11:06 PM Jak_o_Shadows: To avoid having to set a z-height
11:11 PM Jak_o_Shadows: I aint 3d printing today
11:11 PM Jak_o_Shadows: the extruder only wants to run backwards
11:13 PM Jak_o_Shadows: Blown stepper driver maybe?
11:13 PM Jak_o_Shadows: So i'm gong to use popsticks
11:25 PM rue_shop3: Jak_o_Shadows, so reverse the motor and deal with it later? you dont use retract anyhow do you?
11:25 PM Jak_o_Shadows: I tend to retract a bit, yeah.
11:26 PM Jak_o_Shadows: could turn that off.
11:26 PM Jak_o_Shadows: reversing the motor - well, if the wiring connectors are sensible (which they might not be, because reprap), it'd be easy
11:26 PM rue_shop3: just flip over the 4 pin connector on the baord to the motor
11:26 PM rue_shop3: ABCD -> DCBA
11:27 PM rue_shop3: unplug, replug, done
11:28 PM Jak_o_Shadows: yeah.
11:30 PM rue_shop3: The_Jester_, hows the db25 holder going?
11:31 PM rue_shop3: The_Jester_, er...
11:31 PM rue_shop3: https://www.thingiverse.com/thing:1561617
11:31 PM rue_shop3: ?
11:32 PM rue_shop3: https://www.thingiverse.com/thing:2467838
11:32 PM rue_shop3: damn
11:40 PM Jak_o_Shadows: it's weird though
11:40 PM Jak_o_Shadows: it goes in reverse, even when told to go forward
11:40 PM rue_shop3: either the direction pin isn't working or yea, driver
11:41 PM rue_shop3: did you try swapping with say, the X driver?
11:41 PM rue_shop3: this is why they unplug
11:41 PM Jak_o_Shadows: aha.
11:41 PM rue_shop3: E <-> X
11:41 PM Jak_o_Shadows: Yeah. last time this happened, a few months back, it was the driver
11:41 PM Jak_o_Shadows: not the ramps
11:41 PM * rue_shop3 checks to see if Jak_o_Shadows is actually awake
11:42 PM rue_shop3: did you get BGA drivers?
11:42 PM Jak_o_Shadows: BGA drives? I got the a**** drivers
11:42 PM rue_shop3: or are they leaded?
11:42 PM Jak_o_Shadows: leaded?
11:42 PM rue_shop3: yea, with pins around the outside, or BGA under it
11:42 PM Jak_o_Shadows: oh. um.
11:42 PM rue_shop3: you know a BGA right? Ball grid array?
11:43 PM Jak_o_Shadows: yeah, yeah
11:43 PM rue_shop3: they use solder blobs under the chip, they always break off
11:43 PM rue_shop3: esp if its thermally cycling, like every chip its ever been used on
11:43 PM Jak_o_Shadows: leaded
11:43 PM rue_shop3: hmm
11:43 PM Jak_o_Shadows: The spares I bought are also leaded
11:43 PM rue_shop3: k
11:44 PM rue_shop3: ....
11:44 PM rue_shop3: so you have a spare?
11:44 PM Jak_o_Shadows: yeah.
11:44 PM Jak_o_Shadows: I had a spare last time cause Iorignally bought too many
11:44 PM Jak_o_Shadows: then I bought 5 new spares
11:44 PM rue_shop3: ....and this has happened beofre
11:44 PM rue_shop3: and you didn't just try a spare when it acted up?
11:44 PM Jak_o_Shadows: yeah
11:44 PM rue_shop3: :/
11:45 PM Jak_o_Shadows: I swapped it to the spare when it acted up
11:45 PM rue_shop3: k, did it work?
11:45 PM Jak_o_Shadows: yup
11:46 PM theBear: seems that safety-switch popping last week and the first server reboot in around 400 days, pissed off the old 6gb mirror root drive a bit... i know it was claiming to be long dead in all kinds of lifetime hours counts for maybe 3+ years now, but i didn't really believe it, what would a hd that old know about it's time of death over a decade later ? bit more than i thought apparently <grin>
11:47 PM rue_shop3: good thing it was a mirror?
11:48 PM rue_shop3: timer_one_shot_mode()
11:48 PM rue_shop3: http://libopencm3.org/docs/latest/stm32f2/html/group__timer__file.html
11:50 PM theBear: still is maaaaan, the 'new server' isn't even 3 years into config and pre-switchover testing <grin> tho i did finally get it booting properly off a soft-raid boot and root 'drive' yesterday, which is a big step towards being ready
11:51 PM rue_shop3: then this is a good test for rebuilding a drive?
11:52 PM rue_shop3: mdadm....
11:53 PM theBear: turns out there are a few little gotcha's you gotta be aware of to make even the futuristic grub v2.x total re-write boot properly off a raided boot fs, and then further the kernel gives retarded stacktrace/halt errors on a very much "can't find rootfs" issue when you pointing it at a raid rootfs, instead of the traditional and somewhere more useful dumping of the partitions/blockdevs it can see and how it names them, and ya know, mentioning that
11:53 PM theBear: the issue is not finding the rootfs, rather than a bunch of dump codes most of which are scrolled off the terminal before you get a chance to blink anyway
11:54 PM rue_shop3: sounds like when I needed to know where by backup inodes were
11:54 PM rue_shop3: it was the first time I'd ever cared about them
11:55 PM theBear: mmm, after all these years of the 'new tool' mdadm, i think i finally getting the hang of it... tricky one, so many damned modes and commands/options, and many of them with kinda generic/similar sounding names (create and build and assemble, they all kinda sound like similar things, but they sure as heck aren't in mdadm land, and if yer doing the old shifty drive-juggle create-mirror-with-missing-member trick cos yer ain't got the hd space to shift
11:55 PM theBear: everything off both drives to create the array, you don't wanna do anythingwrong at that stage
11:56 PM rue_shop3: add the spare, rebuild it, then take out the old one?
11:56 PM rue_shop3: I had to change a drive on one of my software arrays, there wasn't as much blood as I was anticipating
11:57 PM theBear: heh yeah, the old manual specified inode offset game, i've played it many times (you know how i'm a magnet for broken things and obscure problems, things like that and the hard facts and what moves actually DO what in bootloader and bios/efi boot processes and things about boot records and offsets and partitiontable format details i suspect i'm one of the leading authorities on, just cos ya know, most people never have the misfortune of needing to
11:57 PM theBear: even consider that stuff, while i've waded and nearly drowned in it several times )
