There is a way to get into jog mode without going through the home routine. There is a seperate artical on this for VR milling 2.
The reason for doing this is usually for maintanance and you must

Home the machine afterwards before running a program.
When you connect to the machine the operator panel is in Home Mode. The Jog Auto and MDI options are not available.
If you double click betwean the Home X and Home XYZ buttons the menu showing Jog Auto and MDI become available.
In VR Milling 2 the secret button is located about 3mm to the left of the Home button and midway between Home all and Z axis only. Just double click in this area until the jog menu apears.
