This article covers the complete wiring schematic of the Vision Miner 22 IDEX V4. Use it as a reference when troubleshooting electrical connections, replacing components, or verifying wiring after maintenance. The printer uses two controller boards: a Duet 3 Mainboard 6HC (Board 0) and a Duet 3 Expansion 3HC (Board 1), connected via CAN-FD bus.
High-voltage (mains) wiring between the power supply, SSR (solid-state relay), and the main board. This section is for reference only � do not service mains wiring yourself.
Hotend heaters, temperature sensors, and extruder motors connect to the Duet 3 MB 6HC (Board 0). Both toolheads (Left / Tool 0 and Right / Tool 1) wire back to this board.
The three Z-axis leadscrews are driven by motors connected to the Duet 3 Expansion 3HC (Board 1). The expansion board communicates with the main board over CAN-FD.
The Z-probe connects to the expansion board (Board 1) at 1.io4.in. A servo motor for probe deploy/retract is driven from out9 on the main board. An ESD protection output is configured on 1.out4.
