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.
RepRapFirmware 3 pin names and assignments
| 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_0 | exp.pa21 | Pin on Expansion Header | |
| EXP_1 | exp.pa22 | Pin on Expansion Header | |
| TWD0 | exp.pa3, twd0 | Pin on Expansion Header and Temp DB Header | |
| TWCK0, twck0 | exp.pa4 | Pin on Expansion Header and Temp DB Header | |
| SPI0_CS1 | spi.cs1 | Pin on Temp DB Header | |
| SPI0_CS2 | spi.cs2 | Pin on Temp DB Header |
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 .
