I'm wanting to drive four steppers from the Arduino CNC shield ; I'm not using GBRL . The motors will be used in a remote-control device, but not all of the motors will need to run together.
I have now found that the enable pin (8) on the CNC board is the same one for all for motors. So if I want to use just one motor they all have to be enabled, wasting power (and getting warm!).
Apart from attempting to cut tracks on the board and re-wiring to unused Arduino pins, is there a way of acheiving my aim?
