I also wonder if anyone have tried using bigger drivers. I would like to use my Nema 23 3A steppers with DQ542MA drivers, which can handle 4.2A. Do you need the Pololu drivers or is it possibly just connect other drivers as you connect the Pololu drivers to the RAMPS? Does the Pololu driver work in a different way compared to other drivers?
This document shows that the Pololu driver is working at 1000 microseconds and the DQ542MA at 5050 us. Is that something that needs to be considered before attempt to connect it the the RAMPS?
