Just found this board here.
Also through some searching found cheap treadmill boards work also. Any experience with those?
After many hours of use my X3 motor controller board puffed some smoke. I'd rather not pay $200-250 for a replacement.
What are my options? What have others done?
KBIC125 board is what I replaced mine with. cheaper and infinitely better. adjustable EVERYTHING.
good to hear! I've been meaning to go through and make some adjustments to mine (i left everything stock) to get the minimum speed correct for Mach3
