90 degree offset
If some of your parts are placed with a 90 or 180 degree offset, there are a couple potential root causes:
The feeder's rotation value needs adjustment
When setting the position of a feeder, the rotation value you enter is equal to the initial rotation angle that the part is picked at. Adjust the Rotation
field for the feeder of the part you notice is being placed incorrectly in increments of 90 degrees.
The part's vision pipeline needs adjustment
If your rotation offset is consistently 90 or 180 degrees this is less likely, but it could still worth adjusting that part's vision pipeline.
