Problemi calibrazione asse y

Ciao ragazzi. Ho momtato la mia prusa core one e sto facendo le prime operazioni compresa la calibrazione degli assi. X tutto bene ma y non me lo calibra, mi sembra ci siano i dati sullo schermo in negativo sulla y se puo aiutare. Vorrei capire se e un problema di momtaggio.
Grazie mille a tutti

RE:

Hoping my poor Italian is up to the job of understanding your question. 🙂

If X calibrates but Y does not, then you should first check the pulleys on the "X" and "Y" motors.

Look inside the printer. The "Y" axis motor is on the right. If you look into the hole in the motor mount, you should see the teeth on the pulley. The shoulder that has the grub screws should be on the top.   If you then look to the left at the "X" motor, the shoulder with the grub screws should be visible and the toothed part of the pulley is on the top.

It's pretty common for people to mount both pulleys in the same direction, and that's going to cause calibration errors.

That's another possible cause of Y axis issues.
