Duet 3 Tool Board 1LC

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 (v1.2) 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: Duet 3 Toolboard 1LC v1.2
• 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.

FEATURES

• Processor: ARM Cortex M0+ processor running at 48MHz.
• Connectivity: CAN-FD interconnect to the 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 an ultra-subminiature 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).
