Thanks for that Zach.
The rotator position is reported as 0 by the hardware for the 2044 and 1916 logs but no attempt is made to move it. There are no errors.
The 2052 log also shows no attempt to change the rotator position until 03:09;54 when a MoveAbsolute command to 206 degrees is commanded. This translates to -159393 steps.
The move finishes at 03:10:59 because a Halt command is sent. By this time the rotator has moved to 355.6 degrees, that’s -4580 steps.
At 03:10:04 a MoveAbsolute to 359.95 degrees is sent, that’s -52 steps.
This finishes at 03;10:08 at the correct position.
There are no more moves. The long move was halted after a rotation of less than 5 degrees, this may be hardly noticeable.
This seems to show that the rotator is working correctly. Zero is an entirely likely position to be at and when a move is commanded the rotator position changes as expected.
Could SGP be sending a halt command that’s stopping the move?
