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.
