Here's what I did and observed.

1. Connected. Current angle is loaded as 110.
Backlash is disabled, reverse is also disabled.
Limits are set to 0.

2. I click “Mechanical Zero”
Log: Virtual Mechanical Angle is set to zero.
Current angle is also reset to 0.00.

3. I try to make it go to 90.
It rotates CCW by 90 degrees, and as it is moving the current angle field is updated accordingly.
However, when it stops, the current value is set to 9.00 instead of 90.

4. I try to make it go to 0.
It rotates CW, but only by a tiny bit (I suspect by 9 degrees).
And the current angle field is set to 8.10 instead of 81 (I am starting to see a pattern here)

Looks like there is a bug that sets the current angle to only 0.1 of the actual value.

The logs only say what its rotation targets are, together with the commands, but one can see that the second move command parameter (-10278) is only -0.1 of the first one (102780).
