Hi,
I have a new Ultimaker and assembeld it by my self. Everything is working fine.
But when I am printing a wide object like a box of 8x4cm, the nozzle is scratching on the layer he just printed. It is happening when the printer is at a height of approx 10mm.
Only when I am printing something small like a monopoly house, its working fine and do not scretch.
Before each print I run the "bed leveling wizard" and screw each corner to zero. (so it is in contact with the nozzle)
I also tried to start with a bed level of 0,1mm lower, but then the filament is not sticking onnthe bed anymore when printng the first layer.
Somebody know what the problem is?
