I have a Qidi XC-Pro which is supplied with a high temperature and a normal extruder.

The normal extruder has problems printing ASA at its rated 250C and I'm having to use it at 240C as recommended by their support otherwise the teflon tube inside burns and deforms because although rated at 250C it should not be used over 240C.

Qidi support tell me that the high temperature extruder is not suitable for printing ASA because it will wear the extruder out and I have to wonder what the problem would be?
