I followed your steps to the letter but have one remaining question:
nstall KIAUH
edit/create “klipper_repos.txt.example”
comment out all the klipper lines.
Add this line instead: desuuuu/klipper,dgus-reloaded
run kiauh REMOVE EVERYTHING.
Install klipper (will now get it from the correct repo for us :))
install moonraker
=> installed moonsailos instead of fluidd (but this makes no difference)
IMPORTANT THIS IS WHAT WORKED.
In kiauh hit 4 (advanced menu)
Number 2 (Build only) This will build your firmware (basically the same as makemenu and make, but this works without failing due to the RESERVE_PINS error.).
The configuration GUI does not show the same options, as the new version of klipper provides more options. Does it make a difference which port I choose for the “Screen Serial Port”? I can choose two different options for the USART3:
which option is the correct on, or does it it make no difference?
