Just set up mine, same issues , 2-3 times loading the demon lock.
I looked and gene's mouth was partly blocking the exit and not central causing stdm so wanted to see what was up.
Spent an hour removing the assembly and taking of the head ,(pain in the ass) 5 self tapping screws that can only be accessed from the bottom by lifting the through up.
Remounted the assembly without the head, the VUC now works fine, nit sure why, a one kick afair and the angle of the through exit with regard to stdm's can now Be adjusted or altered without gene sculpt blocking it.
Gene's head was slotted back about half an inch further back over the through in mine and Some velcro is Holding it now, for easy future removal/ adjusting, so far so good.
Might be a solution for more machines judging by how far of the head was mounted ..
