Here is a profile that I created from the version of the Prusa Mini, which I adapted a little for the Lerdge IX.

For the moment, it only supports PLA and 2 print quality, 0.2 and 0.15

I will see to add PETG soon.

Sorry, my screens are in french, but I think it's quite easy to navigate in Prusaslicer

• You must start by importing the file named “LerdgeIX_config_bundle.ini”
• In "Print Settings", Printer Settings" and "Filament Settings", select the "Lerdge IX" setting

• You should get this:

• Now all you have to do is add a model for the board, it is already present in the Prusaslicer folder (I attach it to that or you can't find it)
• You have to go to the printer settings -> General -> Size and coordinates
• Click on Bed shape and and the mini_bed.stl file in Model
• The link: C:\Program Files\Prusa3D\PrusaSlicer\resources\profiles\PrusaResearch
• The name is: mini_bed.stl

• Result

• I printed all the black parts of my Mechagodzilla with the Lerdge IX (0.15), the result is really impressive, as well as a Prusa to my amazement !
  
  

PS: I'm sorry for my bad English and the screens in French 😋
