there was a new version of Curaforuarm released, I don’t know where in cura you can check the version but make sure you use the most recent one.

Hi Nicola, After check the video, it seems that even the zero point is above 10mm (we can’t see the zero point clearly), the arm still knock the table. If so please try the calibration steps in this link: https://drive.google.com/open?id=0B-L-tCvknXU9ZXBweVlYRXd5VHM
It might help you. Looking forward to your reply:)
