The Duet 3 Tool board is a CAN-FD connected expansion board for the Duet 3 Mainboard that is designed to provide complete control for a direct drive extruder, associated fans, filament sensor and probe. The mounting holes and connector locations match an e3d Hemera (v1.2) or Hemera XS(v1.3) , however it can be used with other direct drive extruders with suitable brackets. The stepper motor, heater, temperature sensor, fans and optionally Z probe and filament monitor all connect to the Duet 3 Tool board, leaving only CAN-FD and power wires to run back to the Duet 3 Mainboard or Tool Distribution Board.
There are two current versions.
V1.2 – Hole spacing for the E3D Hemera:
V1.3 – Hole spacing for the E3D Hemera XS (11mm closer together).
The overall board dimensions are unchanged.
