QIDITECH Dual Extruder and PETG I have just received my QIDITECH printer, I've have ABS, PLA and two reals of PETG.  I printed a sample using the clear PETG and this worked find, I didn't have to change any of the default settings.

Today I've tried three times to print a simple model using the black real of PETG.  I've created which is essentially just a rectangle, but after a few minutes the extruder starts to drag around filament.

What can I do?  The filament is loaded ok, and it starts out ok, but very quickly messes up.
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.
