I have a 3d printer I got off ebay (A600 Prusa I3 reprap). I have upgraded the extruder to a wades and I must have screwed up the stepper motor cause it no longer will move when trying to control it with Repetier host. I have swapped connections with known working motors and still nothing. The control board is a all in one board, while I'm ordering a new motor I was thinking of ordering a new controller while I'm at it (I like to have a replacement of each part on hand for these types of issues). Can anyone recommend something other than what came with it? I was to still be able to use repetier host and the current motors. Looking for one that is good but not the most expensive out of course. Just need someone to point me in the right direction. Thanks in advance for all the help
