@alessioCentamore it's a nozzle check to ensure the printer can print the model, you need to set the default nozzle diameter from 0.4 to 0.6.

Sorry but you've just repeated what the error message says, but have not explained where it should be fixed. For someone that hasn't seen this message before it's not obvious enough that an issue has been raised (and I've found myself here trying to resolve it).

I added a 0.6 nozzle to my printer so can choose 0.4 or 0.6, I've 0.6 selected both for Printer and Process. Where should the "default" be changed/set to match the selection so the print can begin?
