Product description
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 (v1.2a) 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.
The overall board dimensions are unchanged.
The connector pack includes the following:
FEATURES
Processor | ARM Cortex M0+ processor running at 48MHz |
Connectivity | CAN-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) |
