There is no timer, the geos thread sleeps on a conditional variable which is triggered by uio_sercos3 in the function UsrCb_t3(). > > The system is idle: > > > > 0.01 0.02 0.00 1/114 2374 > > Was this after the application was running for a few minutes?

The geos thread and the other CNC threads do not have much work to do since they were not completely ramped up.
