It might be a pot adjustment, but I don't know what pins to measure voltage from, and the minimum I can get (measuring from the pot to GND) is 1.71V
The motor makes a very loud high pitched whine and is impossible to turn, but won't move when I give it a move command. it's running off a 12v 18A power supply.
The old drivers work, but one went kaput so we decided to upgrade, but the new stuff isn't working now
