Setting Up a Duet 3 6HC for Voron 2.4 R2 with a 1LC Tool Board and Voron Tap

If you're setting up a Duet 3 6HC with a Voron 2.4 R2 (350x350x350) and a 1LC tool board with Voron Tap, this guide will walk you through configuring your SD card and firmware.

Step 1: Prepare the SD Card

1. Format the SD card as FAT32.
2. Download the latest RepRapFirmware (RRF) from Duet3D GitHub.
3. Copy the firmware files to the /firmware folder on the SD card.

Step 2: Generate the Base Configuration

Use the RepRapFirmware Configuration Tool to generate the JSON configuration file.

• Board: Duet 3 6HC
• Motion System: CoreXY
• Build Volume: X: 350mm, Y: 350mm, Z: 350mm
• Endstops: None (Voron Tap handles Z probing)
• Z Probe: Switch probe (digital switch via CAN toolboard)
• Extruder: Specify based on your hotend (Rapido, Dragon, Revo, etc.)
• Hotend Max Temp: Set as per manufacturer specs
• Bed Heater: Define AC/DC heater settings and SSR control

After entering the details, download the configuration files.

Step 3: Modify config.g for Voron Tap & Tool Board

1. Enable CAN bus communication for the 1LC tool board:

   M950 P0 C"1.io0.out"   ; Define probe signal
   M558 P8 C"!1.io0.in" H3 F120 T6000 A5 S0.005 ; Set Voron Tap parameters
   G31 P500 X0 Y0 Z0      ; Adjust Z offset later
   

2. Set up the extruder and heater:

   M950 S0 C"1.out0"       ; Assign heater control to the toolboard
   M563 P0 D0 H1 F0        ; Define tool 0
   G10 P0 X0 Y0 Z0         ; No offsets
   M572 D0 S0.05           ; Pressure advance (tune later)
   

3. Set up CAN bus address for 1LC:

   M950 S0 C"1.out0" ; Assign heater to CAN toolboard
   

4. Adjust motor steps, currents, and speeds as needed.

Step 4: Install & Update Firmware

• Upload and install firmware via DWC (Duet Web Control).
• Use the following commands to update firmware manually:

  M997 B0  ; Update Duet 3 6HC firmware
  M997 B1  ; Update 1LC tool board firmware
  

Step 5: Verify and Test Configuration

• Test motion and homing:

  G28 ; Home all axes
  

• Test Voron Tap triggering:

  M119 ; Check endstop status
  

• Calibrate Z Offset:

  G31 P500 X0 Y0 Z-0.1 ; Adjust based on real offset
