Are PCB files of Linistepper available ? I'd like to build one.
I've run into a problem with the LiniStepper board. No problem at all assembling it, but it drives the motors I've connected to it with 3 steps forward, then 1 step back, then repeat. I've tested all diode orientations, resistor values, shorts between heat sink and power units, etc.
There were a couple of things tht weren't clear, and maybe this is the problem: the orientation of the blob capacitors.
I have C5 and C6 with the printing toward the 5W resistors;
C2 and C4 with the printing away from the PIC;
C3 with the printing toward the PIC.
Any hints on what to look for next? Thanks,
Tim Iafolla
