OK then yeah that isn’t the issue then.
Update: I have swapped a working motor driver into the not working slot and it does not work. Alternatively I have tried the motor in question on a different axis and it works smooth. Is is possibly it’s the ramps board or possibly still software? Has anyone heard of a non working Sanguinololu1.3a?
Yes, it could very well be your Sanguilnololu: It seems to not be the motor, it’s mechanicals, or wires; not to be the Driver; since it seems to work sometimes, I think it’s not the ATmega chip nor the software. I’d guess the Sanguinololu’s solder joints or traces. You could put the axis’ driver on some breadboard, wire it up, and jumper it to the proper pins. (or even other pins if you fiddle with Sprinter/pins.h)
(Terminology-wise, you might avoid ‘ramps’ as that may mean the http://reprap.org/wiki/Ramps board to many.)
I’ll be damned! I flipped the board over and look at this!
Can someone confirm those are supposed to be soldered? I bought the board ass’d!
Wow, yes those should absolutely be soldered. Just so happens that that’s the X axis as well. I hope a dab of solder fixes that right up for you. Looks like you found the problem. I would give Norcal reprap a call or email about that one, I assume you bought it assembled and “tested” from them.
Hah. Here’s the instructions on soldering those bits: http://reprap.org/wiki/Sanguinololu#Soldering_Sanguinololu_Core
(note the “If your motors move erratically,…” bit.)
Yep, basically you aren’t getting the right stepping since it’s not making a solid connection. I hope soldering works for you.
I soldered the connectors and now the axis works. the motor driver for the X no longer works. When I switch out a working motor driver I have no problems on any axis. So close!
Did it work before you soldered the board? I assume you took out the stepper driver before soldering. You might have to bite the bullet and buy another driver. I would bet Norcal should want to help due to all those issues you had with the board.
Loose connections or hot swapping the connections (as maybe seen in the movie) could destroy the driver: http://www.pololu.com/catalog/product/1182
Since those loose connections were MS1/2/3 I wouldn’t think they would destroy the driver since it’s just a microstepping jumper, but who knows.
perhaps. I am ordering a new driver. here to hoping this is the last thing I will need to buy except filament.
There’s always kapton tape or hairspray to buy for the heated bed if you are using ABS.
I’m starting with PLA, but I do have kapton tape and hairspray handy.
