I have a Tevo Tarantula 3D printer.
I'm trying to print a calibration cube.
The slicer is Cura and is set for a 1.75 mm filament extruded by a nozzle of 0.4 mm, with a heat bed temperature of 60°C and extruder 200°C.
As seen in the image I stopped the printer after a minute, when I noticed that the filament wasn't sticking to the hotbed.
I've also made other tests, but the result is the same - the upper right part of the print lifts and touches the moving nozzle.
How could I resolve this? Any advice?
