11:53 AM rue_bed: https://www.barnardhealth.us/human-brain/images/2125_2461_739.png
11:57 AM Tom_L: how much is actually used?
11:57 AM rue_bed: its a folding diagram, I need to print it, and scribble some things on
11:57 AM rue_bed: there aren't many detailed ones like that
11:57 AM rue_bed: the major question is in regards to how the mechanical structure determines the logical function layout
11:58 AM Tom_L: another question is what triggered yours to get you up?
11:59 AM rue_bed: yar
12:00 PM rue_bed: might as well drag myself around for a bit, I'll prolly collapse again in a bit
12:01 PM Tom_L: monday should be fun
12:01 PM rue_bed: ugh
12:17 PM rue_bed: for the cnc machine, using the drillpress parts
12:17 PM rue_bed: I have an idea for the collette
12:18 PM rue_bed: I screw a "knob" into the drawbar point of the colette chuck, that I can use a "fork" to wedge in, thru the release slot
12:18 PM rue_bed: balancing it might be fun
12:49 PM rue_mohr: zhanx_, ....isn't there an easy was of generating a laser interferometer to be able to get an idea of profile for the surface of a peice of glass???
07:37 PM zhanx_: there should be rue_mohr
07:38 PM zhanx_: also we need to work out why my extruder stepper only goes forward not reverse
07:40 PM zhanx_ is now known as zhanx
07:51 PM rue_mohr: oooh
07:52 PM rue_mohr: it was the retract then that was scrwing you up
07:52 PM rue_mohr: the direction pin isn't working
07:52 PM rue_mohr: are you sure you set marlin up for the right ramps baord?
07:52 PM rue_mohr: is the driver ok?
07:52 PM rue_mohr: maybe they blew the solder joint for the reverse pin
07:53 PM rue_mohr: trace the DIR pin on the stepper driver back to its arduino pin, see if thats all good
07:53 PM rue_mohr: <rue_mohr> it was the retract then that was scrwing you up << when you said it was pushing filament out before it started th print
07:53 PM rue_mohr: that was it trying to retract
07:54 PM rue_mohr: wow, the problems your having are noting like the stuff I faced
07:57 PM zhanx_: i swapped the driver the same thing
07:57 PM zhanx_: what should i check next
07:58 PM zhanx_: BOARD_RAMPS_14_EFB is the board
07:59 PM zhanx_: i swapped the stepper motor also
08:01 PM zhanx_ is now known as zhanx
08:24 PM zhanx: well rue_mohr that solves it
08:24 PM zhanx: I changed the Extruder pins around reversing 0 and 1 and it works now
08:37 PM rue_shop3: what pins?
08:38 PM rue_shop3: the motor pins?
08:40 PM zhanx: #define E0_STEP_PIN 36
08:40 PM zhanx: #define E0_DIR_PIN 34
08:40 PM zhanx: #define E0_ENABLE_PIN 30
08:40 PM zhanx: #ifndef E0_CS_PIN
08:40 PM zhanx: #define E0_CS_PIN 44
08:40 PM zhanx: and my board just died
08:40 PM zhanx: magic smoke came out
08:40 PM rue_shop3: why did you have to redefine the ramps 1.4... you should not have to do that
08:40 PM rue_shop3: what board smoked?
08:40 PM rue_shop3: you just changed the pin definition in the firmaware?
08:41 PM rue_shop3: arg, what are you doing!?!
08:41 PM zhanx: the mega died
08:41 PM rue_shop3: wtf
08:41 PM zhanx: one sec getting a pic
08:41 PM rue_shop3: how does that happen
08:41 PM rue_shop3: ARG
08:41 PM rue_shop3: that should not be possable
08:42 PM rue_shop3: WTF WHO IS SWITCHING ME BETWEEN UNIVERSES THAT SPELL POSSABLE AND POSSIBLE
08:42 PM zhanx: i changed nothing but the driver location and the pins
08:42 PM rue_shop3: dammmmmit
08:42 PM zhanx: and it worked, then it stoped
08:42 PM zhanx: stopped
08:42 PM rue_shop3: you should NOT have to redefine the ramps 1.4 definition
08:42 PM rue_shop3: oooooooh damnit
08:43 PM zhanx: https://imgur.com/a/ABTs0pU
08:43 PM zhanx: that is not a ramps issue
08:43 PM rue_shop3: how do I "start from scratch" and go over EVERY detail of your printer with you to make sure everything is right????
08:44 PM rue_shop3: the ONLY thing that can do that is a short from +12V to vcc
08:44 PM rue_shop3: :((
08:44 PM zhanx: that is I need a new ups for the printer
08:44 PM zhanx: how can i short that
08:44 PM rue_shop3: so, if you get a new arduino and put it in, it'll smoke right away
08:44 PM zhanx: board is done right?
08:45 PM rue_shop3: the ramps board will have a failure on it too
08:45 PM zhanx: yep
08:45 PM rue_shop3: pull off the arduino and meter between +12 and +5
08:45 PM rue_shop3: I'm guessing 24 ohms or less?
08:45 PM zhanx: one sec
08:47 PM rue_shop3: damnit, now every semi on the whole project needs to be checked to see if its fried
08:48 PM rue_shop3: this stuff didn't happen to ANY of the 4 printers I'v built up
08:48 PM zhanx: uploading that was a pita to take a pic of due to focus
08:48 PM zhanx: https://imgur.com/a/WWTSM9N
08:51 PM rue_shop3: this is the ramps board?
08:51 PM zhanx: yes
08:51 PM rue_shop3: dont see anything actually wrong tho
08:52 PM zhanx: the blemish is discolored more on my end
08:52 PM zhanx: but it tests fine
08:52 PM zhanx: think it was smoke
08:52 PM rue_shop3: those are the fuses
08:52 PM rue_shop3: screw that, hows the arduino?
08:53 PM rue_shop3: but does the ramps have a short btweent the 5V and the 12V
08:53 PM rue_shop3: is it possable one of the long leads touched the arduino board?
08:53 PM zhanx: might be as everything is testing fine on the ramps
08:54 PM rue_shop3: hah, you need a better camera to take a pic of everything
08:54 PM rue_shop3: and I need sleep and rest
08:54 PM rue_shop3: two, totally different, completely unrelated things *apparently*
08:55 PM zhanx: normal and normal
08:55 PM rue_shop3: take the arduino, alone, and flash it with the 'flashing led' program (if it will) see it its alive
08:55 PM zhanx: ok i am gonna send you this mega as a gift, since i know you can fix that part and order a new one friday
08:55 PM zhanx: k
08:55 PM rue_shop3: just power over usb, completely dissconnect from the printer stuff
08:56 PM rue_shop3: does the mega power up?
08:56 PM zhanx: shows up on lsub
08:56 PM zhanx: lsusb
08:56 PM rue_shop3: you didn't use the 5V from the mega to power anything, did you?
08:56 PM rue_shop3: they use a sot23 5V regulator and there is no current available for anything
08:56 PM zhanx: nope
08:56 PM rue_shop3: I dont get it
08:57 PM rue_shop3: you need to find out if anything caused it tho
08:57 PM zhanx: what led should light up?
08:57 PM zhanx: i have 2 red ones still
08:57 PM rue_shop3: if you just plug in a mega, you have like a 80% chance if'll just blow up
08:57 PM rue_shop3: one is power, there is one that they use for stuff, if it programs its probabaly ok
08:58 PM rue_shop3: I had an avr drop an io pin once for no reason, I chalk that up to just china
08:58 PM zhanx: it took the program
08:58 PM rue_shop3: but prettymuch everything has been just fine
08:58 PM rue_shop3: well wtf
08:58 PM rue_shop3: you saw smoke, right?
08:58 PM rue_shop3: you smell it too, yes?
08:58 PM zhanx: oh yea
08:58 PM rue_shop3: ok, what blew up
08:59 PM zhanx: first pic
08:59 PM rue_shop3: you onyl powered one pic
08:59 PM rue_shop3: sorry I cant type
08:59 PM zhanx: https://imgur.com/a/ABTs0pU <- look next to c12
09:00 PM rue_shop3: oh, yea the regulator blew up
09:00 PM zhanx: ok i see what i did
09:00 PM zhanx: I mounted the ramps board from front (usb plug) to rear
09:01 PM zhanx: not from the large row in the rear and sent power to the ground
09:01 PM rue_shop3: you cant reverse the ramps baord, there is a pin offset
09:01 PM zhanx: i missed on whole row on it
09:01 PM rue_shop3: hu???
09:01 PM rue_shop3: offset by 1?
09:02 PM zhanx: china
09:02 PM zhanx: that is all i can say
09:02 PM rue_shop3: damn
09:02 PM rue_shop3: oooh, this is not being a good project for you
09:03 PM rue_shop3: damnit
09:03 PM rue_shop3: carefull plugging things in, eh?
09:04 PM rue_shop3: you can get a schematic of the arduino board, see if you can pin down what that it
09:04 PM rue_shop3: is, I thihk its a regulator
09:08 PM zhanx: yep that killed my pc
09:22 PM furrywolf: my assumption would be the larger part near it is a lot more likely to be a regulator
09:24 PM furrywolf: which also looks to be fried, as well as the more-obvious smaller part
09:24 PM furrywolf: I'd assume a lot of the board is gone if you got the power backwards.
09:25 PM zhanx: back
09:26 PM furrywolf: <furrywolf> my assumption would be the larger part near it is a lot more likely to be a regulator
09:26 PM zhanx: i am cutting the traces to that sot now
09:27 PM zhanx: rue if china followed the schematic right i can cut that out and it will still work
09:28 PM furrywolf: is there a small bubbled spot or hole on the big 3-legged part next to it? your photo is.... a good example of why cell phones are not cameras.
09:28 PM zhanx: was a bubble spot
09:29 PM furrywolf: I wouldn't have too much hope for the board, then, unless you got lucky and those parts shunted enough current to protect other things.
09:30 PM zhanx: well i removed it and the computer didn't shut off this time
09:31 PM zhanx: shows up in lsusb
09:38 PM rue_shop3: wow I fell asleep again
09:38 PM rue_shop3: geez
09:38 PM zhanx: ok rue_shop3 i cut that part out
09:38 PM zhanx: but
09:38 PM rue_shop3: ok regualtor?
09:38 PM zhanx: no power to the drivers now
09:39 PM rue_shop3: hu!?
09:39 PM zhanx: wait
09:42 PM Tom_L: man, i got nothing done today
09:42 PM zhanx: hooked back up the 12v and it shut off the pc again
09:43 PM Tom_L: shared supply?
09:43 PM zhanx: soon it will desolder itself as its getting hot
09:43 PM zhanx: no
09:43 PM zhanx: usb to mega and 12v to the ramps
09:46 PM Tom_L: last i knew you had that thing working.. what happened?
09:46 PM zhanx: my extruder decided to go one direction
09:46 PM zhanx: so i pulled the ramps board to change the driver to test it
09:47 PM zhanx: plugged it in wrong i think for the ramps board to mega
09:48 PM Tom_L: i put 24v thru one of mine once
09:48 PM Tom_L: not ramps or mega but another board
09:50 PM zhanx: well that mega board is done
09:52 PM zhanx: i should have looked closer at the board
09:52 PM zhanx: this is being sent rue as a gift so he can fix it and have it
09:52 PM zhanx: the big smoke i saw was a resistor going out
09:54 PM zhanx: thats ok, it will give me time to redo my wiring and stuff
09:54 PM zhanx: wow my connection sucks tonight
10:11 PM rue_shop3: >:\ I'm gonna have to use a opto-coupler for colume contontrol casue I havn't got a damn stereo volume pot thats a reasonable size?!?!!?
10:12 PM katsmeow: bad idea, optos shift parametersover the years, unless it's jusy on-off
10:12 PM * katsmeow has digital sterio pots in thos cale boxen
10:12 PM katsmeow: AARRGG
10:12 PM * katsmeow has digital sterio pots in those cable boxen
10:14 PM zhanx: so this is how i hooked it up wrong and blew the board https://imgur.com/a/nAxzbh9
10:15 PM katsmeow: rue, use 4066 or etc fet analog gates, with different scaled resistors on each gate
10:15 PM zhanx: Tom_L, no plug in boards like that
10:16 PM katsmeow: those aren;t aligned
10:16 PM zhanx: nope i was in a hurry for no reason
10:16 PM zhanx: cost me 10 bucks
10:17 PM katsmeow: next time, have a reason
10:17 PM zhanx: yep
10:18 PM zhanx: kat it all started when the mega 2650 lost a driver pin
10:18 PM zhanx: i was trying to troubleshoot it
10:18 PM zhanx: but
10:18 PM zhanx: yea
10:18 PM Tom_L: ahh that's what happened...
10:20 PM katsmeow: on a page like https://imgur.com/gallery/27zRbVU , saving the post doesn;t save the videos, how do you save the videos?
10:20 PM katsmeow: i need to save them to play them in vlc because the browser does;t play them
10:21 PM zhanx: https://i.imgur.com/2cdNsC3.mp4
10:21 PM zhanx: https://i.imgur.com/ofKB1uQ.mp4
10:21 PM Tom_L: i right clicked and save video as...
10:21 PM katsmeow: where do you get those urls?
10:21 PM zhanx: https://i.imgur.com/Px5TcwS.mp4
10:21 PM zhanx: right clicking them
10:21 PM katsmeow: Tom, all the "save video" etc are grey'd out
10:21 PM zhanx: https://i.imgur.com/IVc8ZC1.mp4

10:22 PM zhanx: https://i.imgur.com/uUlC87f.mp4
10:22 PM zhanx: that is all of them\
10:23 PM katsmeow: ok, thanks
10:23 PM zhanx: no problem i am on the fast machine for once
10:24 PM zhanx: tomorrow is one year abouts and the alienware is mine
10:33 PM katsmeow: FF refused toget them, but wget got them
10:34 PM * katsmeow pounces
10:35 PM furrywolf: meep!
10:35 PM furrywolf: I've had a pretty un-useful day, unfortunately... just lacking energy.
10:36 PM katsmeow: got too hot here today, too fast, got nothing done also
10:38 PM furrywolf: nothing wrong with the weather... just something wrong with me.
10:39 PM * katsmeow hands over some r-ribose,, or something like that
10:46 PM katsmeow: D-ribose?
11:17 PM katsmeow: woooo, finally dropped below 80f outside!
11:18 PM * furrywolf curls up next to katsmeow for an early bedtime
11:18 PM * katsmeow wraps around furry's neck, sticks her nose in his ear and purrs like a ww2 bomber engine
11:19 PM katsmeow: https://en.wikipedia.org/wiki/D-ribose
11:19 PM * furrywolf thinks kat is feeling more feline than usual. :)
11:20 PM katsmeow: only with you, everyine else in here is a human or a bot
11:21 PM katsmeow: Medical uses
11:21 PM katsmeow: D-ribose has been suggested for use in management of congestive heart failure[7] (as well as other forms of heart disease) and for chronic fatigue syndrome (CFS), also called myalgic encephalomyelitis (ME).[8]
11:22 PM ffurrywol: bah, freenode is being annoying lately.
11:25 PM ffurrywol is now known as furrywolf
11:25 PM * katsmeow points furry to his pm window
11:27 PM * furrywolf doesn't have a separate window for messages... they go in whichever window I have active.
11:27 PM * furrywolf fails at third person, a clean sign of sleep being needed
11:27 PM katsmeow: that's a serious drag
11:35 PM rue_mohr: AHA!
11:35 PM rue_mohr: https://dl.packetstormsecurity.net/irc/kaiten.c
11:35 PM rue_mohr: there is the code the hackers are tyring to run!!!
11:36 PM katsmeow: a small japanese submarine?
11:38 PM rue_mohr: I was right about them haivng hacked machiens join an irc server and listen for commands
11:39 PM katsmeow: yeas, not a new scheme
11:39 PM katsmeow: so next step is detecting a nick is hacked
11:40 PM rue_mohr: channel is #whatever
11:41 PM katsmeow: if i join there now, does that mean i am hacked?
11:44 PM rue_mohr: their usign irc.daddy.su
11:45 PM rue_: try that agian
11:53 PM rue_: channel is #DumPz
