Current Issues

• Display is landscape, requiring alternative mounting
• Pause and Cancel print buttons do not work

  Features

This firmware was inspired by Creality printers' touchscreen firmware. Some features include:

• Status message available on most screens
• Z offset, manual and automatic leveling
• PID autotuning
• Volume adjustment
• Brightness adjustment
• BLTouch reset shortcut (if a BLTouch is installed)
• Playing sounds using M300 (the frequency parameter is the index of the audio file)

Focus was also put on making this firmware as easy and safe to use as possible from a user perspective.

Compatibility

This firmware should be compatible with printers equipped with the following hardware:

• 480x272 DWIN T5UID1 touchscreen
• Single extruder
• Heated bed
• (Optional) Single controllable fan
• (Optional) Bed leveling sensor (including a BLTouch)

It could also work on machines equipped with more hardware (dual extruder, etc.) but will lack on-screen controls for such hardware.

Testing has been done on the following machines:

• Creality CR-10S Pro
• Longer LK4 Pro*

*screen is currently landscape, need to do new graphics and config for portrait.

Prerequisites

You have to use this modified version of Klipper. Make sure to enable the serial connection to the screen while configuring the MCU firmware.

The only modification required to your Klipper configuration file is to add this section:

[t5uid1]
firmware: dgus_reloaded

For a list of available options, see the sample-t5uid1.cfg file.

Example Klipper configurations are available in this repository.

Modification / Compilation

You can make modifications to the firmware by opening the DWprj.hmi file in DGUS Tools.

After finishing your modifications, you will need to press the Generate button to create the 3 required binary files.

You can then run the rename script and flash your touchscreen using the resulting DWIN_SET folder.
