Just picked this up from craigslist yesterday (I know, I risked it) and made 1 beautiful print. I then got excited and went for a 14 hour print overnight… Well i woke up to a mess and the Y-axis not working. I switched the X & Y axis on the driver board and the Y axis is fully functional. That leads me to believe it’s the stepper driver on the board.

Does anyone have an idea where to get a replacement driver board or stepper driver?

If you cant find the part to fix it the dremel idea builder still has a 1 year warranty. Or you can go to support on the dremel website.
