Just joined the forum as looking to purchase a smoothie board and in need of advice.
Almost finished my laser and at the stage of buying and fitting the electronics. I have been thinking about the smoothieboard for sometime and think it will handle all my needs except possibly this one.
My lifting Z table is 1200mm x 600mm and I have fitted leadscrews at each corner to raise and lower it. These are driven (or to be driven) by 4 nema 17 steppers. One on each screw. I thought about one motor and driving the other screws by belts but could not find any belts long enough.
My question is this. I want to drive the 4 steppers together as one axis. Can the smoothie handle 4 drivers from one output. Does it have enough current. I think most drivers only need a few millamps and most controller boards the current must not exceed 100 milliamps I think. I have seen in the smoothie documentation that you can links the pins of 2 outputs together. Could I link the 3 of the axis on the 5x board together to produce enough to drive 4 stepper drivers?
if not does anyone have any ideas how I may be able to do this.
