after some extended research and a bug report dit i found a nice error that is provided with this profile...i print in absolute mode ( M82 ) and this profile contains a HARD CODED M83 code ( in scripts -> starting script )this is causing the print to fail badly (in my case , over extruding 500% ) can you triple check the profiles please ? as the point of a profile is to get the correct settings, not to get a broken printer by using wrong commands in a custom start script :( the current version from 07/05/2021 generate a Gcode like this M82some more codeM83some more codestart Gcode of objectThank you Greetings from PowerChaos
