Hi,
I watched a youtube clip the other night where a chap had added two additional stepper drivers to his sanguinololu by partly using another sanguinololu board which seemed to be connected to the E axis and a power supply and was printing on a prusa with three extruders, guess what, I did not save a link or fully grasp what he said but only later concidered copying his idea.
Did anyone else see the clip and or has anyone succesfully added aditional drivers to sanguinololu 1.3a with a veiw to adding multiple extruders to the printer if so please help.
