The Duet 3 Roto Toolboard is designed to integrate easily with the E3D Revo Roto extruder and the Revo hotend heaters and temperature sensors. The following connect using the E3D supplied connectors for easy wiring: extruder motor, a two or three wire heatsink fan, the Revo heater and thermistor and the secondary temperature sensor. In addition a 2,3,or 4 wire part cooling fan, 4 IO ports for endstops, filament monitor and Z probe, a neopixel header, and a Duet 3 scanning Z probe coil can be connected.
This reduces the number of wires needed to two power wires and a twisted pair for the CAN-FD bus.
|Processor features||32-bit, 120MHz ARM Cortex M4F|
|Networking/Comms||CAN-FD interconnect to Duet 3 CAN-FD bus|
|On-board stepper driver||1 x TMC2240|
|Stepper driver features||Up to 1A peak current, micro-step interpolation from any setting to x256, stall detection (Note further thermal testing may allow higher extruder current for Extruders other than the Revo Roto which should not exceed 600mA current)|
|High current outputs||1 x 3.4A, VIN voltage only (80W at 24V)|
|Thermistor/PT1000 inputs||3 x inputs, 2 optimised for 100K thermistors and PT1000 sensors, 1 used for the coil temperature on the SZP coil|
|Medium current outputs||1 x 4-pin (VIN voltage - designed for part cooling using 2,3 or 4 pin fans) and 1 x 3-pin (5V compatible with the Roto heatsink cooling fan using 2 or 3 pin fans). Both are PWM-controlled output with tacho input|
|Inputs/Outputs||3 x on-board I/O connectors for endstop, switches, filament monitor, Z probe. 1 x footprint for a switch or optical proximity sensor|
|Accelerometer||Integrated LIS2DW accelerometer|
|Inductive Sensor||Integrated LDC1612 inductive sensor for scanning Z probe|
|Power monitoring||VIN voltage reporting|
