stepper motors slipping or not moving or irratic etc , is mostly down to either trying to run the stepper at a higher speed than it's capable of this can manifest it's self in many ways . such as low voltage , not enough current , incorrect setup between what you have the stepper driver set for and ...

no is the simple answer , not without firstly changing the stepper drivers , and then modifying marlin or whatever software your looking at using there are 3 phase stepper driver chips available for example sanyo STK673-010 ,these use the same step/direction input so may be an option , depends if yo...
