Problem with prusa mk3s,pallete 2s pro,prusaslicer

Hi I have a problem I have prusaslicer with p2pp you work or did everything as your guide or found the right point for the blob I added the script but when I start it prints the extruder goes to purge but does not extract and does a lot of retraction with your test extracts without problem not that the script is for mmu and not palette 2 and that it has to modify something thanks in advance greetings alain
