    Default Bridgport Interact Series 1 TNC 145 Control - Repair Needed

    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

    ...check the Tachometer feedback brushes inside the axis motor. Dirty or worn out brushes will cause problems.

    Hi Danny
    Check your brushes and if they are OK maybe the servo card is playing up
