Hi All,

While using Robot surface simulation I just noticed that there's always a certain excess of painting on the edge of the part, due to the deceleration on Robot's movement when reaching the final tag on every stroke (which is exactly on part's edge), and going through the retract/approach path, even though the brush is OFF. When slowing down the animation it can be clearly seen that due to the deceleration of the robot the painting gun stays longer over that area on the edge when moving from one stroke into the coming one.

So in order to compensate for that I manually moved all those tags on the edge slightly beyond the part, so that I prefer to have some painting waste than having quality issues on the edge of the part due to painting excess.

This way the result is the expected one in terms of painting deposition, but if I then try to edit the surface trajectory again I receive an error message stating "Path computation failed for the selected surfaces and given Approach direction", and if I try to update the Surface Trajectory then the changes are lost (the tags return to their initial position on the edge of the part)

Which is the right way to handle this situation or am I missing something?

Take a look on the attached picture and videos  

Thanks in advance and kind regards
