I have the R2E4 boss 9 control and I am receiving the following error (000B temp loss of response from FMDC). I can boot, home, run in MDI (spindle on) and I received the above message quickly under load/cutting and after a few minutes under no load (just running head). I have done the following:

Cleaned and reseated board with no change in result
Would this be a loose connection or perhaps servos need cleaning?

Any thought are much appreciated.
Thank
Peter
