QIDITECH Dual Extruder and PETG
It was a while back I created this post, since then I've have numerous problems / learning curves and now I'm very pleased to say I have a printer that prints perfectly and is set-up correctly.

I must say that the support from QidiTech is first class and during my journey I was sent a new extruder assembly, new extruders and also new print matts, all completely free and covered by the warranty.

I have now printed numerous models successfully.
