I have a xylotex setup, and the parallel cable plugs into the main board. With gecko drives, you have 1 board per axis. How do you plug a cable into it. I am just a little fuzzy. Do you split the connectors off to each drive?

Yes, you can split the wires from a parqallel cable to each drive, or buy a $25 breakout board to make it easy.

if i want to wire up led's to each axis for the front of the panel, which leads would I connect them to? ALso for fusing each axis, which lead, and how close to the rated current should I fuse it? Thanks in advance.
