DH crashing into mandrel

Hi everyone,

We have been experiencing a problem with the X-Winder 4X-34 (Designer V4.22) while winding hemispherical ended mandrels. The problem we have come across is that the delivery head will crash into the hemispherical end when moving in. The DH crashes about a third to a half of the way past the mandrel equator. This all occurs with the mandrel dimensions set as stated in the videos. We have made sure that our initial offsets were correct and these were not the issue. The only way we have been able to get a wind without the DH crashing is by extending the mandrel equators to reduce the hemisphere's radii( I.e. the designer software thinks the hemisphere is flatter than it actually is). We do have a video of this occurring.
