    Can an Adafruit motor shield be stacked under a gshield to add drivers for two additional steppers (i.e. A & B axes) with a gshield providing X, Y and Z axes?

    This would be using TinyG2 and an Arduine Due.

    Thanks, Ken

    I don’t expect this would work. The better way to get more axes would be to use some external drivers wired over to the A and B stepper signals from the Due.

    We need to put the Due pinout on the wiki. Right now the only way to fin this is to look at the g2/TinyG2/platform/atmel_sam/board/due/motate_pin_assignments.h and gShield-pinout.h files in the synthetos/g2 project

    Thanks Alden. Ordered some Pololu DRV8825 modules to attach to the ArDue.

    BTW, can’t seem to locate the gShield-pinout.h file.
