Poeschl / P-Cube-Klipper

The configuration of the klipper/Moonraker/Mainsail installation of my 3d printer.

P-Cube Klipper config

This is my backup place for my currently used klipper config file.

It is base on MainsailOS and includes all of my custom files.

• Klipper Config Ref
• Klipper TMC
• Klipper GCodes
• Moonraker (API) Config
• KlipperScreen (Touchscreen) Config
• CrowsNest (CamProxy) Config
• Spoolman
• Klipper Adaptive Meshing & Purging
• Klipper LED effects

Install peripherals

Enable direct serial via 3-wire

Issue with instructions: Klipper3d/klipper#2913

tl;dr

Adjust /boot/config.txt

The following lines worked for me:

enable_uart=1
dtoverlay=disable-bt
dtoverlay=pi3-miniuart-bt

Adjust /boot/cmdline.txt

Make sure no console is specified for UART debugging.

Adjust printer.cfg

[mcu]
serial: /dev/ttyAMA0
restart_method: command

Touchscreen Rotation

• Comment out line dtoverlay=vc4-kms-v3d ➡ #dtoverlay=vc4-kms-v3d
• Add line display_rotate=2 to rotate for 180°

Touchscreen Driver

⚠ DON'T ever use the install scripts of them ⚠ (They will overwrite all existing config and do strange stuff)
