Duet 3 Tool Board 1LC V1.2

The Duet 3 Toolboard is a CAN-FD connected expansion board for the Duet 3 Mainboard that is designed to provide complete control for a direct drive extruder. The mounting holes and connector locations match an E3D Hermera, 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 Toolboard, leaving only CAN-FD and power wires to run back to the Duet 3 Mainboard or Tool Distribution Board.

Features

• ARM Cortex M0+ processor running at 48MHz
• One TMC2209 stepper driver with stall detection and stealthChop. Maximum output current 1.6A peak, 1.1A RMS
• One medium current output intended for extruder heater, maximum current 5A
• One 3-wire 12V fan output (also accept 2-wire fan)
• One 4-wire 12V fan output (also accepts 2-wire fan)
• 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
• Two push buttons and indication LEDs
• 12 to 32V power input
• On-board 12V, 5V and 3.3V regulators
• CAN-FD interconnect to main controller board and other Toolboards or expansion boards
