I got it today!

Connected to Stellarmate to test with the CCD Simulator.
Hand-controller is not connected.

Slewing to targets seem to go in right directions.

I tried to perform Polar Alignment - it was scary!
Slewed to Polaris and started the procedure.
Instead of going 30dgrs it went full 360 and wanted to go further but I stopped it.
I pressed Park (which I set to 0,270) - it went 360 in the other direction and parked successfully.

Location/date/time is set correctly in KStars

What could be wrong?
