Hello guys,
as there is the Rumba board with availability to control 6 steppers, shouldn´t one be able to use the ramps1.4 and modify it to accept another stepper? If i understand the schematics correctly, one basically needs to source +5V, GND, and 3 unused pins at the Mega2560 to implement enabled, direction and step signals?! Maybe integrate another 3 pin dipswitch to set the microstepping or simply hardwire those inputs.
Are there 3 unused pins accessable at the ramps?
