Can anyone advise about a problem I have with my VM25 milling machine. The spindle speed readout has started to show the wrong RPM and seems to cycle down and eventually only reads zero. Could this be a mechanical fault of some sort. The screen is still backlit whilst running.
Thanks. Steve.

Sounds similar to a fault on my (Weiss) WM16B. Warco advised checking alignment and cleaning the optical sender. This is accessed by removing the cover plate, 6 screws, from the front of the machine head. It’s an awkward task and my readout is still not fully reliable although it’s better than it was.
