Duet 3 Tool Board 1LC

The Duet 3 Tool board: a CAN-FD connected expansion board for Duet 3, designed to provide complete control for a direct drive extruder.

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.
v1.3 – Hole spacing for the E3D Hemera XS (11mm closer together)

Duet 3 Toolboard 1LC v1.3

The overall board dimensions are unchanged.

The connector pack includes the following:

  • JST PH housings + crimps for the Driver 0, OUT1, 2, IO 0,1,2 and Temp connectors
  • 4-way JST ZH tail 100mm+ with plug (CAN in)
  • 2-way JST VH housing & crimps
  • White single ferrules for heater screw terminals

Product Details

Processor: ARM Cortex M0+ processor running at 48MHz.

ConnectivityCAN-FD interconnect to main controller board and other Toolboards or expansion boards.

Stepper Driver: One TMC2209 stepper driver with stall detection and stealthChop. Maximum output current 1.6A peak, 1.1A RMS.

High current outputs: 1 x 5A rated output for the hot-end heater (60W at 12V VIN, 120W at 24V VIN, 24V recommended).

Medium current outputs: One 3-wire fan output (also accepts 2-wire fan); one 4-wire fan output (also accepts 2-wire fan).

IO: Two thermistor or PT1000 inputs. One uses a 16-bit ADC for high resolution reading of PT1000 sensors; one 3-pin filament monitor connector; one Z-probe connector; one footprint to mount a ultra subminiture switch; two push buttons and indication LEDs; 12 to 32V power input; On-board 12V, 5V and 3.3V regulators.

Firmware: RepRapFirmware 3.x (3.4 or later recommended for using the accelerometer with input shaping).
