This is firmware to run on an Arduino Pro Micro (preferred) or Arduino Nano to interface a popular style of wired CNC pendant to the PanelDue port of Duet electronics. Build it using Arduino IDE.
For a full guide to building the pendant, see the Duet3D wiki here.
Pendant to Arduino Pro Micro wiring:
| Pro Micro | Pendant | Wire colours |
|---|---|---|
| VCC | +5V | red |
| GND | 0V COM CN LED- |
black orange/black blue/black white/black |
| D2 | A | green |
| D3 | B | white |
| D4 | X | yellow |
| D5 | Y | yellow/black |
| D6 | Z | brown |
| D7 | 4 | brown/black |
| D8 | 5 | pink (if present) |
| D9 | 6 | pink/black (if present) |
| D10 | LED+ | green/black |
| A0 | STOP | blue |
| A1 | X1 | grey |
| A2 | X10 | grey/black |
| A3 | X100 | orange |
| NC | /A /B |
violet violet/black |
Arduino Pro Micro to Duet 3 IO_0 connector or Duet 2 PanelDue connector wiring (3- or 4-core cable):
| Pro Micro | Duet |
|---|---|
| VCC | +5V (red wire) |
| GND | GND (yellow wire) |
| TXO GND |
Through 6K8 resistor to IO_0_IN (Duet 3) or URXD0 (Duet 2) Also connect 10K resistor between GND and IO_0_IN (Duet 3) or URXD0 (Duet 2) (blue wire from resistor junction to Duet) |
To connect a PanelDue as well (the Arduino Pro Micro passes the PanelDue commands through to the Duet):
| PanelDue | Pro Micro / Duet |
|---|---|
| +5V | +5V/VCC (red wire to Ardiuno or Duet) |
| GND | GND (yellow wire to Ardiuno or Duet) |
| DIN | Duet IO_0_OUT (Duet 3) or UTXD0 (Duet 2) (green wire) |
| DOUT | Pro Micro RXI (blue wire of PanelDue cable to green wire of pendant cable) |
