Adding another stepper motor (3 replies)

Hi there reprappers

I have been given a Prusa Mendel (aready assembled and working) in university which is driven by a Sanguinolulu board, and have been given the task to design a rotating part that is driven by a stepper motor (its movement is independent of the axes' and the extruder's motors). I am not entirely sure if it is possible to use the current Sanguinolulu board or if I will need another controller. I have access to an Arduino UNO and EasyDriver, which I could presumably just hook up and use to control the extra stepper motor, although ideally I'd want this motor to be controllable from within the same printer interface (printrun) and if there is a possible way of doing it without using the Arduino UNO that would be great. This is the one I'll be using if that will make any difference.

As you may be able to tell, I have very limited knowledge, but pointers in the right direction would be really appreciated as I found the amount of info on the internet to be slightly overwhelming and the time-frame I am working with is somewhat limited.

Thanks in forward, and apologies if this is in the wrong section/forum.
