3 axis version

[gielbloks]

is it possible to add 3 steppers onto the board?
by tapping into 4more pins from th stm32f103?

this is needed for a pan/tilt function on my printer as well as the extruder,or can you bring out a version with 2 extra stepper motor driver inputs? (connection solderd directly on the stepstick)

don't need 3 boards on the gantry this way (weightsavings)

regards giel
