My breakout board is Accu-Step. When I wired step/direction to Arturo's spindle control board I wired them to axis 4 on the BO board. Couldn't see anywhere else, but it doesn't seem right.
Edit: After staring at the BO board for an hour or so, I figured that enabling axis A on motor tuning and setting step to 5 & dir to 9 on pport 1 should to the trick.
Also.
If you tie the error lines of the Pixies together, as suggested in the PDF, a fault on one axis will shut down all the Pixie's. This should allow the use one Pixie ENABLE output for OUT. SVO-ON.
you may need a driver transistor if the Pixie can not sink the relay current
Can I tie the 3 enable lines of the Pixies together to connect to OUT. SVO-ON? Would that help to sink the current?
