My QiDi arrives in a couple of days. Got it off ebay. Customer support was very responsive to pre-sales questions - even though they have been on Chinese New Year holiday for a week.

I want to print in Nylon and Carbon Fiber PLA/ABS. Does anyone have a recommendation for a hardened nozzle? I'm not certain if this has MK8, MK9, or MK10 style nozzles.
