GENERAL SUPPORT Renishaw Alarm 1092 Unexpected surface found

I am running single surface touches with my renishaw spindle probe. I am using p9811 to do single surface touches. sometimes when i do z touches, it gives me the alarm listed in the title after the first touch of the 2 touch cycle. I have tried cleaning all of the glass, changing batteries, putting kroil in the base of the probe, it does not feel sticky, and I tried running it with the lights off. It seems to be pretty random, doesnt matter where I touch in z but it seems to be every 10 touches or so and it seems to be getting worse. Has anyone had this and solved the problem?

I’m purely guessing here, but maybe the spring in the housing has become “loose” over time, so the fast movements is jerky enough to trigger the probe sometimes.

So if you can try and reduce the fast movement feedrate, then you can see if that might be the cause of your problems.

Try increasing your back-off amount.
