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 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.
1$\begingroup$ Can you add an image of your print and the stl image? $\endgroup$– Fernando BaltazarMay 14, 2020 at 5:03

$\begingroup$ have you configured z-offset yet? $\endgroup$– linuxdanMay 26, 2020 at 4:40
A distance of 15 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.
