Possible duplicate of How to align all work area cutting directions
I thought someone posted recently somewhere – Facebook maybe – about having better control over Route Angle instead of the 10 degree increments, but it may have been about Boundary Set Back. Sorry, don’t recall.
Anyway, I noticed that issue as well where Area 1 and Area 2 don’t quite line up regardless of what you set as the Rotation Angle. That’s probably a result of how the Areas are mapped influencing the mowing calculations. Having more granular control of Route Angle would help.
