I'm trying to build a 3D printer using a Megatronics 2 controller. I got Pololu DRV8825 stepper motor drivers for the 1/32 steps. My problem is the Megatronics 2 wiki. In one place it says that each DRV8825 needs to use all 4 of 4 pin jumpers and 2 sentences later it say "Pololu has released an updated version of the DRV8825, that doesn't need the fourth jumper".
Does anyone know how I tell if I have the updated version or not? Will something just not work or will I burn something up if I use the wrong number of jumpers? Should I try 1 motor with 3 jumpers to see if I get smoke and then try 4 jumpers?
