Orient the Controller Board so the USB and Power
ports are facing the
REAR
of the machine as shown
in the photo below. Use the two (2x) M6x12mm
screws to attach the Controller Board to the Left Y-
Axis Rail by inserting the screws into the
countersunk holes drilled in the aluminum plate
and threading them into the rail.
Loosely re-install the cover of the controller.
We have more work to do around the
machine before connecting the wiring harness
and want to be careful not to accidentally
damage the controller.
