Topic: Y-Axis Stopped Working after Stupidity

I've run into a little issue that I'm not sure how I will fix.  I was fixing a bad connection for my fan that cools at the print head, and I (not thinking clearly) shorted out my machine (I feel like a total idiot for not disconnecting anything beforehand).  It seems like everything is working fine afterwards, though, except for the Y-axis.

Is the board toast?  I'm really hoping that I didn't nuke my machine, but I'm prepared to take responsibility for my stupidity.  I'm mainly wondering if there are any procedures that I could go through to possibly reset it and/or determine what I fried.

After swapping around the stepper motors, I've determined that the y-axis motor is fine, so the problem seems to be at the board.  Is there any way to reset the board?  I'm worried that I've caused some major harm, and I'm mainly posting in hopes of someone knowing what to do in this situation.  Thank you for your help.

Re: Y-Axis Stopped Working after Stupidity

since you have been around here a while I will assume you have the old sanguinolol board with the separate pluggable stepper driver modules... try switching two(x,y) of these around and see if that changes anything if so then A4988 stepper driver is fried they run about 12 bucks I think... don't have a link handy but you can find them about anywhere that sells 3d printer stuff or feebay.

Ronsii, you rock.

I just switched out two of the drivers and now everything works.  I have no clue why it did not work with them the other way around, but all I know is that it works now!  Thank you for your suggestion.  I was really worried that I nuked my board and would be paying for a new board because of my mistake.  Thanks again!

Re: Y-Axis Stopped Working after Stupidity

You might want to check the voltages on the trim pots, there is a thread around here somewhere that has the settings listed... I just saw one the other day that Adrian posted. Not sure why/how that fixed it but glad to hear it works smile
