Caution! If you are used to wiring other members of the Duet series, be aware that the VIN + and - terminals on the barrier strip of the Maestro are the opposite way round compared to Duets that use a 2-way screw terminal block to connect VIN.

Name on PCB	RRF 3 pin name(s)	RRF2/3 assigned by default	Notes
BED HEATER	!bedheat	Y	Default H0, but you need to create Heater 0 to use it
E0 HEAT	!e0heat
E1 HEAT	!e1heat
FAN0	fan0	Y
FAN1	fan1	Y
FAN2	fan2	Y
X STOP	xstop	Y
Y STOP	ystop	Y
Z STOP	zstop	Y
E0 STOP	e0stop
E1 STOP	e1stop
Z_PROBE_IN	zprobe.in	Y	this can be used with smarteffector
Z_PROBE_MOD	zprobe.mod, servo	Y
BED TEMP	bedtemp
E0 TEMP	e0temp
E1 TEMP	e1temp
C TEMP	ctemp
PS_ON	pson
	exp.pa21
	exp.pa22
	exp.pa3
	exp.pa4

Note: In RepRapFirmware 3, stepper drives 0,1,2 and 3 map to X,Y,Z and E0 (driver 4 is not assigned). Reassign these with M584 if needed.

Could you please post a demonstration of what pins on the motor output go to what pins on the stepper? The cable color coding differs quite a bit across cables and features various crossing.

Seth, the 1A-1B and 2A-2B nomenclature is the standard motor naming convention for the poles of the motor. Pole 1 gets connected to 1A and 1B, Pole 2 gets connected to 2A and 2B. If the motor rotates backward from the desired direction or the Duet board reports “short to ground” then swap the A-B on one of the poles.

Can you use 5V for the proximity probes? I can’t tell if the probe_in pin is 5V tolerant.

Can we get an SVG version of this file? It seems to come from an SVG but JPG artifacts are everywhere.

I have linked it - Dozuki does not allow SVGs to be uploaded .
