Scenario: nozzle 1 = HIPS, nozzle 2 = ABS. When switching from one nozzle to the other the the printer does not do a purge. The result is that the first few passes on the prime tower are in the air. This means the following layers also print in the air which means that I end up with spaqghetti and the prints fails.
My thinking is that if I could add a purge before the prime tower the print should finish properly. Is this possible when using two nozzles? Can’t find a setting in BL to enable this.
