Hi guys!
I tried DRV8825 stepper drivers today on my ramps 1.4, it wouldnt turn the motor, then I went back to my A4988 drivers to test, and now they wont turn the motors. they move a little but act like they are not getting enough voltage. I also noticed that my extruder will not heat up now, but the heated bed will, I was wondering if the DRV8825 might've fried my ramps mosfet or something? Does that sound reasonable? I am trying to figure deduce what is wrong, but I am stuck. I made sure to check the pins on the DRV8825 and they seem to match with the board, but its hard to see underneath the headers on the board..
