12:00 AM _unreal_: last page
12:06 AM _unreal_: ve7it, I'm bringing my daughter to her mothers tomorrow morning
12:06 AM _unreal_: after that I have what 6 days to play
12:06 AM _unreal_: and help get this stuff working
12:07 AM _unreal_: I DO have a wire harness that I pulled and its "complete" or so I hope.
12:07 AM ve7it: ok... justBionic Beaver
12:07 AM ve7it: found itBionic Beaver
12:07 AM _unreal_: the other sats saddly the wires run internal. and you have to cut them to get them out. they are crimped in place
12:07 AM _unreal_: ?
12:07 AM _unreal_: beaver?
12:08 AM _unreal_: so when I get to it tomorrow I'll see if I can make heads or tails
12:08 AM ve7it: that should help.... cpu is going crazy
12:08 AM _unreal_: ?
12:09 AM _unreal_: I "believe" the wire pinouts are going to be the same
12:09 AM _unreal_: the latest sat I pulled from was a seatel 4006
12:14 AM _unreal_: ve7it, this is interesting DA23DBB http://www.bertda.com/Companies/EAD%20motors/Brushless%20DC%20Motors/Nema%2023%20BLDC%20up%20to%20190%20oz-in.htm
12:17 AM _unreal_: ve7it, if that last link is correct following the dbb one which are the motors I sent you. they have upto 80oz/in peak torque
12:19 AM ve7it: that looks great... I need to build up the cable, so I can plug the motors into the control board... that connection diagram will really help as it shows all the power, phase and hall connections
12:20 AM _unreal_: I dont know if it shows the correct wires colors though
12:21 AM _unreal_: though 123 abc the order doesnt mater so long as the right hall is matched with the right winding
12:22 AM _unreal_: You can identify the hall's in the motor by doing a DIODE test
12:22 AM ve7it: I will check... should be able to build the cable tomorrow
12:22 AM _unreal_: as I recall I believe I added a db9 cable
12:23 AM _unreal_: that WAS the original plugging into those motors or so I think? the colors may match
12:23 AM _unreal_: those colors on the doc do not match my motor
12:24 AM ve7it: pretty sure I have enough connectors ... yes, one motor has a pigtail hanging on the db9
12:24 AM _unreal_: so identfying the windings is easy.
12:24 AM _unreal_: as to the halls do a diode test
12:24 AM _unreal_: that will easlly tell you the + - and the hall signal wires
12:25 AM ve7it: I will verify the pin numbers from the drawing... colors not so important as I will have to use whatever wire I have
12:25 AM ve7it: cool
12:26 AM _unreal_: thats how I got the big motor with encoder working
12:28 AM _unreal_: + lead on my multi meter goes to the hall signal wires. and the negative multi meter goes to the -v as I recall
12:28 AM ve7it: excellent.... It also verifies the driver board was driving 3 bdlc motors... one with encoder that went to the controller board
12:29 AM _unreal_: yep
12:29 AM _unreal_: ya the quadrature encoder signals went to the db34 sometehing like that connector
12:30 AM _unreal_: ! that I can varify tomorrow
12:30 AM ve7it: my eyes are slamming shut here... its time for bed... too much eating this wek!
12:30 AM _unreal_: ya 1:30 am here
12:30 AM _unreal_: and I have to be up at 6 to drive the kid
12:30 AM _unreal_: oh let me post one quick picture
12:30 AM _unreal_: progress of the new cnc
12:31 AM ve7it: drive safely... tty tomorrow... I did catch a pic earlier
12:31 AM _unreal_: ve7it, https://drive.google.com/open?id=1fCGveW9ftNgEdcqa857odj_Deort-nNB
12:32 AM _unreal_: not that one
12:32 AM _unreal_: just concepting
12:33 AM _unreal_: not sure I'm happy with the aluminum angle
12:33 AM ve7it: cool now to convert your air hockey table to cnc....
12:33 AM _unreal_: NEVER
12:33 AM _unreal_: and OH you like that
12:35 AM _unreal_: the more I think about it I REALLY should switch to steel angle, AND rotate the angle 90 degree's
12:35 AM _unreal_: I am with out question adding complication
12:36 AM _unreal_: tomorrow I'll help you pinout the motor driver board
12:36 AM _unreal_: night
12:38 AM ve7it: maybe even pieces of box tubing to bolt carriage to the linear rail pucks
12:38 AM ve7it: like 2x4"
12:38 AM ve7it: I would be more ridgid than angle
12:39 AM ve7it: rigid
02:08 AM Deejay: moin
04:56 AM jthornton: morning
04:56 AM XXCoder: yo
04:57 AM XXCoder: I bought board for my laser engraver. making sure laser connection is populated, and bought 3 wire cable too lol
05:04 AM jthornton: that sucks that you have to do that just to get it to work
05:04 AM XXCoder: yeah
05:05 AM XXCoder: I suspect they hacked grbl around so laser works on 2 pin connector
05:05 AM XXCoder: well I can always use it for something else
05:05 AM XXCoder: dunno what tho. robot arm? lol
05:05 AM XXCoder: I wonder how strong cardboard robot arm would be lol
05:16 AM jthornton: could be pretty strong if enough glue and cardboard is used
05:17 AM XXCoder: not just materials and binding
05:17 AM XXCoder: structure also
05:33 AM X704 is now known as tiwake
06:41 AM Tom_L: morning
06:41 AM jthornton: morning
06:42 AM Tom_L: you see that plant video? Beechcraft blew up yesterday
06:42 AM Tom_L: 3" liquid nitrogen line blew
06:42 AM Tom_L: https://www.nbcnews.com/news/us-news/beechcraft-manufacturing-plant-explodes-wichita-kansas-injuring-15-n1107866
07:02 AM jthornton: rainy weekend here
07:03 AM Tom_L: same here
07:04 AM Tom_L: must be fog cause it's wet under the patio too
07:04 AM jthornton: going to try and get some more painting done monday if it gets warm enough
07:04 AM jthornton: fog/mist here
07:05 AM Tom_L: "smoke on the water"
08:11 AM Loetmichel: WTF? Firefox using 6 GB RAM and 25% of that I7 each on two tasks? maan that thing got bloat lately :-(
08:55 AM jymmmm: Good morning folks :)
08:56 AM jymmmm: _unreal_: Got the projector, not bad. Haven't set it up properly, only on the ceiling, lol.
09:27 AM gregcnc: it's not firefox, it's websites
09:31 AM Loetmichel: *COUGH* *SPIT* MAAAN is that dusty in that corner... just found where i cut the "guest room" sat cable a decade ago to have 2 cables in the living room for recording... as that TV has been on about 2 times in the last 20 years i reversed the cut (thanks to double female F-couplers) and the TV in the guest room already has 33 channels and is still scanning. *SUCCESS!*
09:38 AM jymmmm: Loetmichel: So why are you messing with 20yo tv?
09:38 AM Loetmichel: Jymmm: i didnt
09:39 AM Loetmichel: i tried to get the 40" tv i bought a day before xmas to run properly
09:39 AM jymmmm: Ah gotcha
09:39 AM Loetmichel: in the guest room ;)
09:39 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17625&g2_imageViewsIndex=1
09:39 AM Loetmichel: aka: my "snore bed" room ;)
09:40 AM jymmmm: Loetmichel: So, you bought a 40" TV for the guest room so it won't be used for another 20 years? lol
09:40 AM Loetmichel: no, the living room TV hasnt been used in the 15 years we live here (apart from being set up)
09:40 AM jymmmm: Dang, does that tilt straight down?
09:41 AM Loetmichel: the guest room TV is for gaming/reading books before sleeping
09:41 AM Loetmichel: yes, it does tilt a bit more, sufficient to be read from a comfortable position
09:42 AM Loetmichel: and there is a raspi connected to it and a pretty powerful notebook on the nightstand
09:42 AM Loetmichel: so i can even (remote) game all my steam games ;)
09:48 AM jymmmm: haha, wouldn't have been better just to get a 72" TV instead???
09:48 AM jymmmm: maybe a 102" even :)
09:49 AM jymmmm: three of them!!!
09:49 AM Loetmichel: nope, as you can see its already a bit big there
09:49 AM jymmmm: That's no excuse!
09:49 AM Loetmichel: was just the cheapest >32"
09:49 AM jymmmm: ah ok
09:49 AM Loetmichel: that i found on christmas eve
09:50 AM Loetmichel: 200 eur the TV and 190 for the wall mount and some extra parts like 5m HDMI cables and stuff
09:50 AM Loetmichel: :-)
09:50 AM jymmmm: I'm going to see how well that projector I got yesterday for $28 works outdoors, then maybe have "blackout party" :)
09:50 AM Loetmichel: so i can get from the TV to the nightstand where the PI and the notebook are
09:51 AM jymmmm: 190 for a mount?! ouch
09:54 AM Loetmichel: the mount was 8ß
09:54 AM Loetmichel: 80
09:54 AM Loetmichel: the rest was cabling and things like a keyboard/mouse for the Pi
09:54 AM Loetmichel: :-)
09:55 AM Loetmichel: in retrospect: a cheaper mount would have been sufficient
09:55 AM jymmmm: gotcha
09:55 AM Loetmichel: didnt notice that the 40" TV only weights about 5kg... no idea how they managed that
09:56 AM Loetmichel: the mount is made to carry a 50++kg TV ;)
09:56 AM jymmmm: CRT
09:58 AM Loetmichel: nope
09:59 AM Loetmichel: but something like the Plasma we have in the master bedroom
09:59 AM Loetmichel: that thing was HEAVY!
09:59 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=11615&g2_imageViewsIndex=1
09:59 AM Loetmichel: 46" panasonic plasma display... MAAAN was that fun to hang that on the wall mount without help
10:01 AM jymmmm: What swith all the DVD's?!
10:02 AM Loetmichel: wife collects
10:02 AM Loetmichel: she has about 1500 original DVDs and BRs now
10:02 AM jymmmm: Yeah, but why not rip them to a NAS box?
10:02 AM Loetmichel: and she is getting more as we speak ;)
10:02 AM Loetmichel: because that is still illegal here in germany
10:03 AM Loetmichel: so she refuses
10:03 AM Loetmichel: or at least it WAS illegal for a long time
10:03 AM jymmmm: So what? Not like you are going to sell them
10:03 AM jymmmm: Then you can watch them anywhere in the house
10:03 AM Loetmichel: also she wants to be able to access all the bonus material and i simply have no 30+TB room on the fileserver here at home
10:04 AM Loetmichel: not considering the time it would take to rip them all
10:04 AM jymmmm: Make a new one, storage is cheap now
10:05 AM jymmmm: HAHA, GOT BOAT??? https://www.thedodo.com/in-the-wild/pair-of-enormous-sea-lions-borrow-someones-boat?fbclid=IwAR0mHDWkHu-SnDNG-1S8VuxsCF2TCkwO4U8WTRSFCLU-_0D5dmgiJj20S8E
10:05 AM Loetmichel: i'll get some 10tb disks soon
10:05 AM Loetmichel: and will upgrade the server
10:09 AM jymmmm: Loetmichel: What do you use to rip dvd's ?
10:10 AM Tom_L: cdburner xp
10:11 AM jymmmm: Tom_L you using that to RIP dvd's?
10:12 AM Tom_L: that too
10:12 AM Loetmichel: jymmmm: no idea yet
10:12 AM jymmmm: Tom_L Sys it's just a burner/iso creator, not a RIPper
10:13 AM jymmmm: says*
10:13 AM Tom_itx: https://cdburnerxp.se/en/home
10:13 AM jymmmm: Loetmichel: ah ok
10:13 AM jymmmm: Tom_ Yeah, I read, I dodn't see anything about ripping
10:13 AM Tom_L: wtf is the difference?
10:13 AM * Tom_L rips jymmmm
10:14 AM jymmmm: RIPPING a DVD removes the encryption and copy protections schemes (plural)
10:14 AM Tom_itx: oh, i forget what i used to use
10:14 AM Tom_itx: they've gotten better at encryption since i did it
10:14 AM jymmmm: Then, you can reauthor if you like.
10:15 AM Tom_itx: movies?
10:15 AM jymmmm: Yeah, remove the menus, extra languages, etc
10:16 AM Tom_itx: https://www.techradar.com/news/the-best-free-dvd-ripper
10:16 AM Tom_itx: i don't remember what i used to use
10:18 AM jymmmm: ah ok
10:26 AM jymmmm: Tom_L Quitter ;)
11:10 AM _unreal_: god that is such a long @#$@34 drive
11:14 AM _unreal_: jymmmm, what ever floats your boat ;)
01:04 PM jymmmm: _unreal_: huh?
01:21 PM _unreal_: jymmmm, lol you posted the sea lion link
01:22 PM CaptHindsight: do they still sell DVD's? :)
01:24 PM _unreal_: who
01:24 PM CaptHindsight: they of course
01:25 PM _unreal_: OHHHHHHH they...
01:25 PM _unreal_: of course they...
01:26 PM _unreal_: what was I thinking
01:26 PM _unreal_: nuck nuck... ahh nuck...
01:26 PM _unreal_: everyone still sells dvds
01:26 PM CaptHindsight: Loetmichel: if you're really concerned about not ripping maybe
01:26 PM * _unreal_ goes for more crown ryoal
01:26 PM CaptHindsight: you can find an old DVD "jukebox"
01:26 PM _unreal_: hay
01:27 PM _unreal_: I need a second opinion
01:27 PM _unreal_: I'm not drunk yet so here it goes :)
01:27 PM _unreal_: first a photo
01:27 PM CaptHindsight: held 100's of DVD's, and mechanically swapped them into a drive/player
01:27 PM _unreal_: https://drive.google.com/open?id=1fCGveW9ftNgEdcqa857odj_Deort-nNB
01:28 PM CaptHindsight: did Twitter break again?
01:28 PM _unreal_: if you zoom in you can see the angle aluminum
01:28 PM CaptHindsight: Loetmichel: https://www.ebay.com/p/28022917379
01:28 PM _unreal_: I'm trying to figure out WHAT would be the best/strongest/ridgiest means to connect the X axis to the Y axis aluminum?
01:28 PM _unreal_: I have lots of different materials on hand
01:29 PM _unreal_: I'm just trying to figure out what would likely be the most minimal aproach with the greatest yield
01:29 PM Tom_L: steet T's
01:29 PM _unreal_: ve7it, sup
01:29 PM _unreal_: street t's?
01:29 PM Tom_L: steel
01:30 PM _unreal_: got... link..
01:30 PM ve7it: not much... waiting for coffee to kick in....
01:30 PM _unreal_: waiting for crown royal to kick in
01:30 PM _unreal_: :)
01:30 PM ve7it: hey
01:30 PM _unreal_: ve7it, I'm free now
01:30 PM _unreal_: ahh ve7it your thoughts https://drive.google.com/open?id=1fCGveW9ftNgEdcqa857odj_Deort-nNB
01:30 PM _unreal_: if you zoom in
01:31 PM _unreal_: I have angle aluminum to connect the Y to the X frame
01:31 PM _unreal_: I'm trying to figure out what would be the strongest way to link them with the least amount of effort and the greatest returns in stiffness
01:31 PM _unreal_: sigh. even alcohol does not affect my typing speed
01:33 PM * _unreal_ lol's as he thinks of the Haitian guys at work. who were freaking out as they watched me type one day taking notes on a boat project.
01:33 PM CaptHindsight: Jymmm: if the projectors works invite this guy for sound https://www.youtube.com/watch?v=HFUMk9i6XE0
01:33 PM _unreal_: ttttttttttap ttttttttttap ttttttap
01:34 PM _unreal_: CaptHindsight, projector? OH likely the projecter I linked everyone tothe other day
01:35 PM _unreal_: ya they are not bad. there NOT $800 theater quality but if you get it set in the right location the quality is great. especially for $25
01:36 PM gregcnc: if you don't have horns this big, you're not serious http://www.soundimage.dk/images/RD-horn_sub.jpg
01:36 PM _unreal_: I already have one setup in my daughters room
01:36 PM ve7it: _unreal_, how does the bridge feel for stiffness?
01:37 PM _unreal_: gregcnc, talk about bringing the house down
01:37 PM _unreal_: LOL
01:37 PM _unreal_: bridge VERY STIFF
01:37 PM _unreal_: and I'm going to add a second set of 45's to the leading side of the bridge
01:37 PM _unreal_: the trailing one has them welded on
01:38 PM gregcnc: https://gizmodo.com/horn-subwoofer-takes-up-crazy-mans-entire-basement-5025867 too bad the guy original site has gone 110% conspiracy theory
01:38 PM ve7it: there is your answer... since everything bolts together, you can always change it later if you run into an issue
01:38 PM _unreal_: oh ve7it you can see one of the blue 45's in the photo on the table
01:39 PM _unreal_: its pon the table between the bridge
01:39 PM _unreal_: its on
01:39 PM _unreal_: ve7it, what I'm looking at is the 90 portion
01:40 PM _unreal_: the rectangle part of the vertial on the bridge currently does not tie to the base
01:40 PM _unreal_: so I have a few options
01:40 PM _unreal_: I have a bunch of diffeent types of angle aluminum
01:40 PM CaptHindsight: gregcnc: stable genius conspiracy theories or 9-11 types?
01:40 PM _unreal_: also new, the photo does not refelect, is that I have flipped the rectangles from side to side. so the cutouts the circles/small rectangle are now on the outside of the bridge not the inside
01:41 PM _unreal_: arg... I'm going to have to buy a neww keyboard again. this keyboard is clearly wearing out
01:41 PM _unreal_: few of the keys I have to tap a few times to get them to "key" in
01:42 PM CaptHindsight: wondering how future generations historical perspective will be about the recent +- 2-3 decades
01:43 PM _unreal_: CaptHindsight, I'll have you know I resemble the recent 4 decades
01:43 PM _unreal_: ;)
01:43 PM CaptHindsight: peak stupid or uhmericas greatest period
01:44 PM _unreal_: CaptHindsight, you know what I miss the most though. not being in my teens/20's so much WELL I... DOOO..... but some of the online stuff that does not even exist any more really.
01:45 PM _unreal_: the online quake gaming, heat.net, zone.com msngaming
01:45 PM _unreal_: omg there was an other one and I cant remember it
01:45 PM _unreal_: AHHH...
01:45 PM _unreal_: mplayer
01:45 PM _unreal_: few
01:45 PM _unreal_: I'm not old i'm not old
01:46 PM _unreal_: I dont know what I liked better, mplayer or heat.net
01:47 PM _unreal_: cap?
01:47 PM Loetmichel: there he is gone
01:47 PM _unreal_: sigh
01:47 PM _unreal_: figures
01:47 PM Loetmichel: just wanted to answer his jukebox link and that it is about 1300 disks short of the goal ;)
01:48 PM _unreal_: heh
01:49 PM Loetmichel: _unreal_: seems you are an old fart as well ;)
01:50 PM _unreal_: my daughter tells me that all the time. I tell her its the guacamole
01:51 PM _unreal_: so ve7it what is the current progress and how can I help
01:53 PM _unreal_: ?
01:58 PM ve7it: I am going to start a kicad schematic and document the drivers to motor connection, then I need to figure out how the couple of chips were driven from the cpu board
02:01 PM _unreal_: hence I inclued everything :)
02:01 PM _unreal_: ve7it, I have a few different programmers on hand
02:01 PM ve7it: maybe you want to try following that circuit... I think as a first guess that they just clocked out 3 motor drive values... would like to be able to do that from the microcontrollers
02:02 PM _unreal_: well
02:02 PM _unreal_: the max505 has 4 outputs and only 3 are used
02:03 PM ve7it: just need to work up a schematic and code to drive it
02:04 PM _unreal_: oh interesting
02:04 PM _unreal_: ve7it,
02:04 PM _unreal_: I will send you a photo link of the desoldered board
02:04 PM _unreal_: so you can see what is under the motor driver chiops
02:04 PM _unreal_: chips
02:04 PM _unreal_: VERY slight but differences
02:05 PM ve7it: that helps.... I think the existing board is 4 layers
02:06 PM * _unreal_ tries not to picture his manly slef in the photo
02:06 PM _unreal_: https://drive.google.com/open?id=1fE6JW3r7e_odzj2PmIikGYfI4qShKH2G
02:06 PM _unreal_: wow that uploaded fast
02:06 PM gregcnc: capthindsight crop circles, religious conspiracy, end of times crazy
02:06 PM _unreal_: did I mention I love my reflow tation
02:06 PM _unreal_: station
02:06 PM _unreal_: got all 3 of those chips off in like 1.5min
02:07 PM _unreal_: gregcnc, breath that paper bag deep my son
02:07 PM _unreal_: gregcnc, here try some of this spray paint in that bag... it helps
02:08 PM _unreal_: ve7it, if you need I can pull the max505 from the board
02:08 PM * _unreal_ goes for more alcohol
02:09 PM _unreal_: blond/blue eyed sigh... alcohol does not affect me well
02:09 PM _unreal_: well/much what ever
02:09 PM _unreal_: ve7it, ?
02:11 PM _unreal_: ve7it, I hardly melted the plastic socket as well :)
02:13 PM _unreal_: ?
02:15 PM _unreal_: OH shit ve7it I didnt even notice till now. notice the 1/2/3 I think I probed it out once and forgot about it. the 1/2/3 are likely motor controller 1 2 3 zones between motor coil wires and signal wires for halls
02:17 PM jymmmm: Only 150 speakers?! Pfff amateur
02:18 PM _unreal_: ?
02:26 PM jymmmm: _unreal_: FWIW... I just backed up the usb stick, 480MB zipped
02:29 PM _unreal_: ?
02:30 PM _unreal_: OH 480mb you must be talking about the projctor
02:30 PM _unreal_: I remember that stick being 480mb ish of ish holiday content
03:08 PM _unreal_: ve7it, ?
03:18 PM Deejay: re
03:23 PM ve7it: _unreal_, off filling my face with more food
03:27 PM SpeedEvil is now known as Guest19984
03:31 PM elmo40: don't forget to breath!
03:42 PM jymmmm: Well, the projector CAn read a USB hdd formatted to FAT32 (but not ExFAT)
03:43 PM gregcnc: Looks like McMaster changed to 1 foot increments in material length
03:43 PM jymmmm: Can play MP4, but not ISO
03:43 PM jymmmm: Not sure yet about AVI
03:44 PM jymmmm: gregcnc: from what?
03:45 PM gregcnc: used to be able to order by the inch
03:45 PM jymmmm: gregcnc: ah ok
03:46 PM gregcnc: no I'm wrong it has to do with how the search works
03:47 PM gregcnc: "low carbon steel disc, 3" long, 2" diameter"
03:48 PM gregcnc: I guess short pieces are discs, no matter what
04:01 PM _unreal_: ve7it, naturally
04:05 PM _unreal_: well back to cnc building
04:27 PM elmo40: _unreal_, almost done?? will you make a 4th axis for it?
04:29 PM _unreal_: elmo40, I'm looking at 5 axis
04:30 PM _unreal_: just finished getting an other aspect of the X bridge done
04:31 PM _unreal_: trying to align the damn thing now
04:38 PM _unreal_: sigh
04:43 PM Deejay: gn8
04:44 PM _unreal_: you bastard always leaving us
04:55 PM _unreal_: GOOD FUCKING GOD!!!!! someone lit a BIG ass firework outside
04:55 PM _unreal_: damn that scared me
04:57 PM skunkworks: JT[m]: jthornton: how would you go about installing halcompile on your pi build?
04:59 PM elmo40: _unreal_, aligning it to the bed?
05:11 PM _unreal_: to its self and to the Y axis bearings
05:11 PM _unreal_: no wonder that was off... My cad drawing was off by a mm
05:12 PM _unreal_: ve7it, just put the turky leg down.....
05:28 PM _unreal_: hum
05:33 PM _unreal_: ok any one big on lathes in here
05:33 PM _unreal_: I have an old lathe VERY old lathe and it has a thread on the spindle for a drill press style chuck
05:34 PM _unreal_: wondering if there is maybe a 3-4 jaw huck I could put on it. I just dont know a lot about lathes
05:40 PM elmo40: possibly
05:40 PM elmo40: find the thread details
06:17 PM jthornton: skunkworks, I've not tried to install halcompile on the rpi4
06:42 PM Tom_itx is now known as Tom_L
07:09 PM _unreal_: sigh
07:09 PM _unreal_: soo ve7it how goes it?
07:12 PM ve7it: trying to remember how to run kicad ....
07:12 PM _unreal_: That I may be able to help with
07:12 PM _unreal_: what is the current issue?
07:13 PM _unreal_: I'd have to find it but I got a KICAD foot print for the bldc driver chip
07:14 PM _unreal_: What are you having issues with currently in kicad?
07:20 PM ve7it: cool... just looking for symbols to drop on schematic... they have motors, but not 3phase or ones with hal sensors... just building a new sysmbol
07:21 PM ve7it: I havent looked for the driver chip yet
07:22 PM _unreal_: ve7it, snapeda.com
07:23 PM ve7it: looking
07:23 PM _unreal_: ve7it, https://www.snapeda.com/search/?q=a3936sed&search-type=parts&resistance=&tolerance=&manufacturer=&package=&search-type=parts
07:27 PM ve7it: they want me to sign in :} they dont have the symbol and the footprint is just a plc44 or whatever
07:27 PM _unreal_: I have an account setup
07:28 PM _unreal_: so i can download what ever
07:33 PM _unreal_: ok ve7it great news
07:33 PM _unreal_: I just finshed tracing out this cabling
07:33 PM _unreal_: I'm 99% sure I have the db25 and the db9 and the wire runs are UNcut
07:33 PM _unreal_: so i can trace out the pins
07:34 PM _unreal_: I'm going to assume all of the motors are wired the same
07:34 PM _unreal_: db9 pins 123 are motor windings?
07:34 PM _unreal_: and the remaining 5 used pins are hall ?
07:40 PM _unreal_: ve7it, have you traced out many of the db25 pins on the motor controller?
07:40 PM _unreal_: at this point I can confirm what pins go to what
07:40 PM _unreal_: I'm starting to build a list
07:41 PM ve7it: not yet... so far I am assuming the connections on the last page of the seatel manual are close
07:41 PM _unreal_: ok I can tell you right now
07:41 PM _unreal_: the DB9 pins 1 2 3 are motor wires
07:42 PM _unreal_: and the 1 2 3 pins current one I'm testing go to pins 2 14 15
07:42 PM _unreal_: on the motor contorller db9
07:42 PM _unreal_: so I have a working cable setup for both the db9 and db15 so I can trace out what the wires are
07:43 PM _unreal_: for the two motor types. even though I only sent you the db9 motors I did send ya the encoder :)
07:43 PM _unreal_: I'll keep tracing
07:43 PM _unreal_: I believe this wire group goes to the motor controller that is closest to the edge and farthest from the max505
07:44 PM ve7it: 4 is +5, 5,6,7 are hall wvu and 8 is gnd?
07:47 PM _unreal_: ok so u2 bottom right pin on the side closest to the db25 is pin2 on the db25
07:47 PM _unreal_: checking manual to identify which phase it is
07:49 PM _unreal_: ok thats pin28
07:49 PM _unreal_: so motor controller U2 a3936sed pin28 goes to pin2 on the DB25
07:53 PM _unreal_: DB25 PIN 14 goes to a3936sed pin 21
07:54 PM _unreal_: so a3936sed pin 17 should go to db25=pin15
07:57 PM _unreal_: DB25 PIN 4 goes to a3936sed pin 6
07:58 PM _unreal_: DB25 PIN 3 goes to a3936sed pin 4
08:00 PM _unreal_: DB25 PIN 5 goes to a3936sed pin 8
08:02 PM _unreal_: DB25 PIN 16 goes to a3936sed pin 9 VDD
08:02 PM _unreal_: ve7it, you got all that?
08:04 PM _unreal_: so for the db9 now
08:04 PM _unreal_: db9 pin1 goes to db25 pin2
08:05 PM _unreal_: db9 pin2 goes to db25 pin14 db9 pin3 goes to db25 pin15
08:07 PM _unreal_: db9 pin5 goes to db25 pin5
08:08 PM _unreal_: db9 pin4 goes to db25 pin16
08:10 PM _unreal_: db9 pin8 goes to db25 pin17
08:11 PM _unreal_: db9 pin7 goes to db25 pin3
08:11 PM _unreal_: db9 pin6 goes to db25 pin4
08:11 PM _unreal_: ve7it, thats all of the db9 pins
08:12 PM _unreal_: ve7it, ?
08:16 PM _unreal_: any one around?
08:17 PM _unreal_: sup
08:28 PM _unreal_: ve7it, let me know if that helps
08:59 PM _unreal_: ve7it, you got those pinouts copyed?
09:25 PM ve7it: yup... and they match the schematic
10:35 PM ve7it: _unreal_, kicad is coming back... got the 3 dip chips added to the libraries, now for the A3936
10:44 PM _unreal_: ve7it, tomorrow I'll pin out the db15
10:45 PM ve7it: it should match the schematic
10:45 PM ve7it: 8 wires for motor and the rest for the encoder
10:46 PM _unreal_: ya
10:46 PM _unreal_: well I figure now that the first motor/chip etc.. has been identifyed everything else is easy
10:46 PM _unreal_: but you dont know what wires from the encoder go to what :)
10:47 PM ve7it: doing the parts for libs has me wondering wth they are doing..
10:47 PM _unreal_: looking at my board the two logic chips I pulled there are no top layer traces under the hcips
10:48 PM _unreal_: I have not pulled the max505 but I can
10:48 PM ve7it: 9-=B, 10=A, 11=index, 12=+5,13=gnd
10:49 PM ve7it: pin 11 index not used
10:50 PM ve7it: where can a post a pdf?
10:50 PM _unreal_: ahh.. do you have a google account?
10:50 PM ve7it: yup
10:50 PM _unreal_: google drive
10:50 PM _unreal_: you have a FREE 15gb of storage just for having an account
10:51 PM _unreal_: just like this here https://photos.google.com/share/AF1QipNjUL9VJW4BIh58ZOHM6jOWS10l43lfzL_nr7FMD-YXm_o6hG63BfTN2Rv6ch6C_Q?key=OVV0UTBXUmF0NXNSR2NKVzdoaFhxQzVTbDI5V3JB
10:51 PM _unreal_: is part of the google photos
10:51 PM _unreal_: have you played with google drive?
10:53 PM _unreal_: I dont want to but I'm going to have to take those angle brackets OFF one more time on my new cnc build and sand them
10:53 PM ve7it: https://drive.google.com/file/d/1nBuZmnfwEIdbjjQ_5sob15Wsc5fHfqwR/view?usp=sharing
10:53 PM ve7it: does that work?
10:53 PM _unreal_: they are just not flat enough and torquing my cars on the rail
10:54 PM _unreal_: si
10:54 PM _unreal_: lots of straight lines
10:55 PM ve7it: the top 1/2 is all 3 motor and encoder connections to the control box including signal names and possible wire colors
10:55 PM _unreal_: NICE
10:55 PM _unreal_: where the hell did you find that
10:55 PM ve7it: 2 from last page in the setel doc you pointed me at
10:56 PM ve7it: like page 123
10:56 PM _unreal_: ? oh ok
10:56 PM _unreal_: so i found it and didnt know it
10:57 PM ve7it: page 122 of 122595_C1.pdf
10:57 PM _unreal_: are you going to try and drive the motor using the current mcu?
10:57 PM _unreal_: or your own setup
10:57 PM ve7it: yup... I thought thats what you wer checking against
10:58 PM _unreal_: err are you planning on trying to use the current controller that is in the box? to drive the motor controllers I mean or drive the motor controllers with your own setup? arduino, STM.. what ever
10:58 PM ve7it: no... I am hoping I can figure out the signal coming onto the driver board in the 15 pin inline connector
10:59 PM _unreal_: AHH ok
11:00 PM ve7it: thats why I need to understand what the 3 dips are doing... by making a schematic, it should become clear (or slightly less foggy!)
11:00 PM _unreal_: ! I think I remember seeing a document that listed that like that pdf you just posted
11:00 PM _unreal_: come to think of it I may have tossed all of my logic boards and just kept the motor controllers :)
11:01 PM ve7it: that would be very helpful... signal descriptions on that short cable from the controller board to the driver board is what I need... then just about anything can talk to the driver board
11:02 PM _unreal_: if I recal correctly it saw a document listing that 15pin inline in one of the PDFs from the seatel site or one of those sights
11:02 PM _unreal_: these parts are again from a SEATEL 4004
11:03 PM ve7it: yea the logic board is way too complicated to reverse engineer... we dont need gps or gyros for most cnc machines
11:05 PM _unreal_: ve7it, its right there on the page
11:05 PM _unreal_: bottom left
11:05 PM _unreal_: da-15p
11:05 PM _unreal_: That is the inline
11:05 PM _unreal_: 15pin
11:06 PM _unreal_: linking the motor controller to the mcu controller sitting below it
11:10 PM _unreal_: I could be wrong
11:11 PM _unreal_: pin 15 on that connector is ground, pin 8 is +vcc from the looks of it
11:12 PM ve7it: I dont think so.... that is the 15 pin connector off the edge of the controller board... its the connections at J6 we are looking for
11:12 PM ve7it: you had me going for a minute!
11:13 PM _unreal_: had me going for a min..
11:14 PM _unreal_: the motor controller board list's that inline as j1
11:14 PM ve7it: wonder if there is a schematic for p/n 121171?
11:14 PM _unreal_: one of my motor boards has a label on it on the inline
11:14 PM _unreal_: 121174 rev a
11:15 PM ve7it: yup mine too... even the schematic for that p/n might show the signal names
11:16 PM _unreal_: at least I didnt send you the board with the REALLLLLLLY thick conformal coating
11:16 PM _unreal_: hehe
11:16 PM ve7it: nasty
11:16 PM _unreal_: I DID send you the chips btw from it
11:17 PM _unreal_: MF'ER of a time getting them off clealy
11:17 PM ve7it: I was surprised these were not coated... they are in very good shape for marine electronics
11:17 PM _unreal_: ya
11:17 PM _unreal_: well they sit inside a doam
11:17 PM _unreal_: dome
11:17 PM _unreal_: at the very top
11:17 PM _unreal_: so they dont typically get splashed much
11:34 PM _unreal_: ve7it, I still stand by what I though. again I could be wrong but I do think that the J1 reference in that PDF at the bottom left may be that interconnection...
11:34 PM _unreal_: https://www.cebix.net/downloads/bebox/max505.pdf
11:34 PM _unreal_: looking at the max505
11:35 PM _unreal_: it takes 8 I/O bits.
11:35 PM _unreal_: That j1/j2 thing shows 7bits
11:35 PM _unreal_: there are only 3 analogs being used because there are only 3 motor controllers
11:36 PM ve7it: j1 is the 44 pin connector on the edge of the pcb
11:37 PM _unreal_: the mcu board?
11:38 PM _unreal_: what about j2
11:38 PM ve7it: pg 95 shows the cable between the pedestal control board and the 3 bldc driver, but no signals :{
11:38 PM _unreal_: https://www.cebix.net/downloads/bebox/max505.pdf
11:39 PM _unreal_: regardless that J2 bottom left of the pdf you posted shows a 15pin and it shows data bits. the max505 takes 8 data bits but its only using 7
11:39 PM ve7it: j2 is the 15 pin db connector on the edge of the pcb... we need signals on J6
11:39 PM _unreal_: ahh j6
11:39 PM BitEvil is now known as SpeedEvil
11:43 PM ve7it: yah I have the 505 part defined.... a lot of the 15 wires could be the signals to write into the 505 dac, but I dont know what the analog mux chip and the 8 bit addressable latch is for
11:44 PM _unreal_: ! that is one part I couldnt figure out
11:44 PM ve7it: when I start connecting the lines one the schematic it may become obvious
11:45 PM _unreal_: ve7it, I hate to do it but I'm half tempted to clear the rest of the parts from the board
11:45 PM _unreal_: and set it up on the mill and maybe mil away the top layer
11:45 PM _unreal_: or bottom :)
11:47 PM ve7it: there are not that many connections... should be able to ring them out 1 by one
11:47 PM ve7it: I want to get all the parts on the schematic then start connecting them as I figure it out
11:48 PM ve7it: I just need the driver chip drawn out
11:51 PM _unreal_: btw one of my boards has a WIRE jump that is a PATCH on the bottom
11:53 PM _unreal_: goes between I believe pin9 bottom right of the u7, and goes to u5 pin 13 I believe
11:53 PM _unreal_: I'd have to look them up
11:54 PM _unreal_: but assuming those two chips follow standard DIP I'm counting from the upper left down across the bottom to the right and back up.
11:55 PM _unreal_: the board with a PATCH is REV J
11:56 PM _unreal_: so I dont know if that is an ERROR in design? or a discovered correction that was never found in other versions
