Motors not working... Suddenly

Hello all, my extruder stepper motor, on my DIY machine, was stalling so I turned up the current pot, now none of the stepper motors work. I've tried everything I can think of:

Turned Pot back down
New ramps 1.6 board
New arduino mega
New drv8825 drivers
Checked all connections
Tried a new stepper motor on all axes

The motors just aren't turning, they're not even "fixed" i.e. powering on.

Anyone got any suggestions? Thanks in advance

... motor voltage there?

Yeah i've got 12v on the stepper driver pin (VMOT) anywhere else to check for motor voltage?

... if all drivers stopped working, then either no 5V for the electonics, missing enable or no step pulses anymore -- check this pins/voltages and get a new driver for testing functionality ...
