Any reason to not use high temp extruder?

The problem with Qidi XC-Pro is not the extruder, but the nozzle. The extruder is designed for printing ABS, PLA, nylon and other generic filaments, but not ASA. The ASA requires a nozzle with a melting temperature of 280-290°C, and most nozzles for Qidi XC-Pro have a melting point of only 270-280°C, which is not suitable for ASA. So when you try to print with a nozzle with a lower melting point than the filament you are using, you should expect the nozzle to degrade over time and eventually fail.
