stepper motor circuit anomaliesPosted by email@example.com 0 points 8 replies
I edited the AN-CM-295 circuit and removed the current comparator circuit.
I set it to full step mode, but the circuit failed to operate. I edited another vesion, placed the comparators back edited the verison to full step only, removed the comparators, and miraculously that one could operate withput the CCMP .
I disabled the chopper by connecting the CHOP input to gnd or leave unconnected.
apparently there are some forces at work that I have not yet identified.
