Hi Luis:
It is operating at 24V. The stepper is rated at 3A and 24-48 V. I have run it with a DRV8825 before. I am using simple PWM - high, low and time delays to pulse from an Arduino board to do simple Full Step, Half-Steps and Micro-steps.
Since fault occurs right at the outset I suspect an over-current(OC) too. If so can it be triggered by incompatible INx pulse combination(high/low side) or some other reasons ? I am currently rebuilding the circuit but got 24 V across VM and VNEG, 3-4 V and 330 mAmps across OUTx pins with prior circuit.
Will get back on sense resistor current/voltage on the rebuilt circuit. Thank you for following up.
