FLSUN QQ doesn't print and stops at Z=15 mm When I try to print something that is not the test model already on the SD, which means when I try to slice something in Cura 4 and than I start the print, the nozzle stops at Z=15&nbsp;mm and only the extruder motor goes foward and backward. I tried to modify the G-code but I didn't solve the problem. I need help because it's my first delta 3D printer and I don't know what to do.
A distance of 15&nbsp;mm is about the height of the probe or Z-offset. That can be a clue.

Compare the G-code from the testprint with the G-code you sliced. It can give you other clues.
