Auto calibration.

[felixpujols007]

Greetings I hope you are well, my name is felix and I am super new working with 3D printers. And I currently have a mini rostock, with a proximity sensor and use of the Melzi board. The questions I have: Using this marlin firmware, the automatic calibration after every print and the firmware does everything automatically? I do not have to point anything, just point the G29 in the print script, to do the autocalibration automatically and then start the impression?
