Hi all, I have a few queries regarding driving multiple stepper motors (11 of them) with individual pololu a4988 drivers and an arduino mega. Excuse my ignorance as I am novice in this area.
1/ My stepper motors are far enough apart that the wires out of them would not all run to a single point where the drivers would be. What cabling should I use to extend the stepper motor wiring? The run length would be about 40cm (total). Should I use shielded twisted pair cabling (as I have seen suggested in another thread)?
2/ Would the 5V supply from the arduino be sufficient for the logic power supply for all the stepper drivers? If not, how is it best to provide the 5V logic power supply whilst keeping the ground separate from the motor supply? (I have read that the two should be kept separate to avoid ?interference?)
