I have observed a behaviour in the printing/priming sequence that I am unable to understand.
Print object is the 2 colored tree frog (https://www.thingiverse.com/thing:329436). Extruder 1one is black, extruder2 is white PETG, am using a y-splitter-type hotend. Support is supposedly extruder 2. Sequence of printing is:
black prime tower, black object, white support, white prime tower, white object
Seems somehow wrong. Why print support with extruder 2 before extruder is primed? Leads to failed prints due to support not properly printed.
Am I doing something wrong?
