We have slippage on focuser motor.

MOAR POWER!

[x] check motor spec for max voltage
Max 48 V for motor and 35 V for driver module
[ ] apply something more then 9 V that we are applying now
We are actually running the motor on 12V.

Running the motor on 17 V caused USB ship in Arduino to drop connection (sometimes temporary and sometimes permanently until power reset).

Probably caused by an interference transmitted via ground connection.

Put the PCB in an enclosure. USB works good, mostly. After some inactivity (15 minutes or 2 hours) USB becomes unresponsive, and needs to be reset.

Reseting it is now easy, with a micro switch on telescope enclosure door:

Closing for now, as it looks like there is no slippage any more. Will reopen if needed.
