I have a Acorn board and there cables not a Oak, but still i am having issues with faults. They are telling me its setting issues but they will just fault out sitting there, some times when there Active high and Low. I just worked through some issues today with Marty and went to finish setup and now i am back to issues. I have random faults and also my X drive now wont hold position and will keep rotating backwards? When it moves backwards my DRO doesn't even change values and it moves a few thousandths? This may not be the correct place for the question, but wanted to let you know i have the same drives from the same date and are having issues. I attached my videos and also a picture of my drives. I emailed them to ask the same question if the Firmware was good and my cables.

When you setup your DMM drives and motors using the DMMDRV software, did you use the TUNING feature of the software, before setting things up in Acorn?
