#hold_current:			0.4
stealthchop_threshold: 	0 		<-------- ALWAYS ZERO! Using stealthchop in fast-paced extrude-retract-extrude sequences will cause it to disable the driver entirely, without throwing an error (the print will continue like nothing is wrong)
#interpolate:			False   <-------- Same thing. The is True by default, which doesnt play nice with extruders
