I'm experiencing a strange problem tonight. Calibration works OK when taking full frames (using subframes still won't calibrate). But a few seconds after guiding has started it is automatically stopped. The log shows

I have no idea what's going wrong. I suspect it might have something to do with the fact that I did a factory reset with my G-11. I set guiding speed to 0.2 (also tried 0.5) and adjusted Ekos accordingly (prop. gain 333 and 133, respectively). The guide star behaves normally with no sudden moves. Nevertheless Ekos keeps telling me the mount was slewing which is not the case. Log is attached.

Any suggestions/ideas? Thans in advance.

Looks like the issue was solved. Either it was a malfunctioning micro switch or it was somehow related to Jnow/J2000 confusion. Once I reset the G-11 to J2000 the problem was gone. For now I just hope it won't return.
