I temporarily mount all the reprap parts on a piece of MDF. This will keep them from moving around while I test. I used my
Sparkfun "Premium Jumper Wires" to attach them to a 25Pin breakout board.
I got a nice 600W ATX power supply on sale at Fry's.
Unfortunately the RepRap motherboard is not moving the motors yet. I get what appears to be good Step and Direction signals to the G540 when viewed on my scope, but no movement yet. Does anybody have any ideas? I am not worried about things like steps/mm yet, I just want to see some movement.
