the b axis isnt moving... you can rotate the scroll by hand, and it moves, but not when you jog it.... the figures in the display also move up and down, and even alarm out when reaching past home position etc.... but the actual b axis stays still..... any suggestions??? cant run anything on the lathe in MDI etc, as it says axis need to be homed... but cant home b axis!

cheers, not sure if this is the right forum, surely theres a CNC lathe forum place???? so complicated on the main forum page!
