Tune stepper motor current - moonglow/FlashForge_Marlin GitHub Wiki

FlashForge motherboard has controllable digital potentiometer and you can adjust VRef value on your stepper driver with it, it will change driver current limit. Rule is simple more current will give you more torque, but also gives more heat ( especially when the motor is stationary ) and in critical situation you can melt plastic motor mount, so you must be careful with that settings.

Default motor currents settings:

Axes	Current	G-Code param
X	0.8 Amps	X
Y	0.8 Amps	Y
Z	0.35 Amps	Z
E0	0.6 Amps	E
E1	0.6 Amps	B

G-Code command M907, will allow you to change default settings, as example: M907 X0.8 Y0.8 Z0.35 E0.6 B0.6

Best place where are can put new settings it be in your start G-code sequences in your favorite slicer software.
