It's a bit of a misnomer. May improve adhesion. Possible to use this but the macro increases compatibility and it can be also used in the slicer startcode (ok here also the clipper command can be introduced) to adapt to different filaments without reconfiguring clipper config. This way, we only have to set the data type (int, float, string, etc) and set any defaults once. Then double check to make sure your pressure advance is still solid. 02 too high, leading to corner bulges. His self-assurance — some would even say arrogance — enabled him.
