Installing Microcontroller Firmware

Overview

From v2.0 onward, Dune Weaver transitioned from custom firmware to FluidNC.

FluidNC Installation (DW Mini, DW Pro, DW with DLC32)

Installation Steps:

  1. Navigate to https://installer.fluidnc.com using Chrome
  2. Select "Connect" and choose your Dune Weaver's serial port
  3. Follow on-screen instructions (may require pressing/holding boot button)

Version Requirements:

  • DW Mini: Use v3.8.3 (supports unipolar motors removed in later versions)
  • Mini Pro with 28BYJ-48 motors: Use v3.8.3
  • Other configurations: Can use latest version
  • DLC32 users: Ensure switches 1, 2, 3 are OFF for both X and Y axes

Wireless Options:

  • Bluetooth: Works immediately via serial connection
  • WiFi: Implemented but not optimized; disabled by default

Configuration Upload: After firmware installation, upload the corresponding config file from the firmware folder via File browser, then restart the board.

File Browser

Motor Direction Verification:

  • Command $J=G91 G21 Y5 F100.0 should move ball outward
  • Command $J=G91 G21 X5 F100.0 should move ball clockwise

Motor Verification Commands

If incorrect, reverse motor directions using pin swaps (Mini) or config toggle (DLC32).

GRBL Installation (Arduino with CNC Shield)

Setup Process:

  1. Install GRBL following these instructions
  2. Manually copy grbl folder to Arduino libraries if needed

Configuration Settings: Input via serial monitor:

$3=2
$22=0
$100=320
$101=287
$110=900
$111=3000
$120=30
$121=30
$131=10

Motor Direction Verification: Same commands as FluidNC. Reverse directions by swapping motor cables at shield if needed.
