would you also please share the gcode file you are trying to print also, would you please check for new updates. we pushed some last night. then updating and trying again i have seen in the logs that your ratos version is not the latest one, so please update everything and then try again well, i see the issue. the new post processor doesnt allow to reprint files that have been processesd with the old post processor. you can temporarily deactive this feature and reprprint the file add this to the printer.cfg and you can reprint it.
bypass_post_processing: True
bypass_post_processing: True
but dont forget to remove it later when you want to upload a new file @miklschmidt can we please add a gcode command that disables the PP for the next print only. instead the need to change the printer.cfg

Hey, sorry for the delay. So I started updates and all, done well. So When I try to print a new sliced cube it say that Prusa Slicer 2.9.0 is not supported? It supports only 2.8.0 and 2.8.1 It is printing right now...

yeah, PS2.9 just have been released yesterday, and we havent tested or added it to the list of supported slicers yet. but you can allow it it by setting:
allow_unsupported_slicer_versions: True
allow_unsupported_slicer_versions: True

So, what is now the best approach to go for. Change Pruser Slicer Version or the other work around. Oh I didn't know that. Okay, so I add those two lines? This are the suggestions: [ratos] bypass_post_processing: False enable_gcode_transform: True or [ratos] bypass_post_processing: True allow_unsupported_slicer_versions: True

jsut use this for the moment to allow 2.9
allow_unsupported_slicer_versions: True
allow_unsupported_slicer_versions: True
if you want to reprint on an older already sliced file run BYPASS_GCODE_PROCESSING before the next print we jsut added this command for this purpose please update again we just pushed it

Latest update (pushed ~12 hours ago) should not throw exceptions at you, FYI, it'll explain what to do if you want to print files generated by unsupported slicers.
