Looking for a SD 1525-10 drive board. I believe my X axis drive board went south and I am looking for a cost effective direct replacement. I may have this one rebuilt depending on what kind of feedback I get here. My control is a Dynapath Delta 20 and I had even toyed around with the notion of adding the 4th axis if I can source a few drive boards on the cheap. Please let me know what you have. I would like to get my machine back up and turning! Thanks.
