Pinout and Wiring

You will need to make a cable to connect the ACE to a USB

Installation Instructions

1. Custom Firmware: Install the latest Paxx12 custom firmware to gain SSH access to your Snapmaker U1.
2. Enable Debug Mode:
   • Connect to your printer via SSH.
   • Execute the following command to enable debug mode:

     touch /oem/.debug

Note

This mode allows user files to persist after a reboot. [!WARNING] Enabling debug mode will reset your Wi-Fi settings. You will need to reconnect to your Wi-Fi network after the printer reboots.

3. Install Extra Modules:
   • Copy ace.py and filament_feed.py from this repository to /home/lava/klipper/klippy/extras/ on your printer.

Important

Rename the stock filament_feed.py to filament_feed_stock.py before copying the new one.

4. Install Kinematics Module:
   • Copy extruder.py from this repository to /home/lava/klipper/klippy/kinematics/.

Important

Rename the stock extruder.py to extruder_stock.py before copying the new one.

5. Configure Klipper:
   • Copy ace.cfg (if provided) to the custom config directory: /config/extended/klipper/.
6. Calibrate Feeding Length:
   • Connect all four PTFE tubes between the ACE Pro gates and the U1.
   • Measure the approximate length of the PTFE line.
   • Subtract approximately 5cm from this measurement.
   • Open ace.cfg and find the feed_length: variable.
   • Enter your calculated value (e.g., if the line is 80cm, set feed_length: 750).
   • Goal: The filament should stop approximately 5cm away from the toolhead after being fed from the ACE Pro gate.
7. Restart: Restart your printer to apply the changes.
