Good afternoon,

I have a Bridgport Interact Series 1 (TNC 145 Control) that keeps losing itself on the X axis. Machine will reference return at low feed but soon looses itself when trying to move the axis in rapid or high feed. The movement looks very rough and jumpy.

The alarm message reads "gross position error (B)"

Is there anyone on here that can help me get up and running again? It's the only CNC mill we have...(I know, I know).

We are based near Tewkesbury, UK.

Thanks in advance.

Danny
