Vast XTR Head Gear Shearing - Image Attache

[[ad...]]

HI Guys,

My team has recognised wear to the Vast XTR head, which has a gear around its opening for adaptor plates.
The issue is when the styli is asked to rotate it will stop roughly 2/3rd of its rotation make a clicking sound and then correct itself but on the odd occasion it will enter the pockets at 90degrees causing a collision.
My presumption is that the styli has been caught in rotation causing the shear(see image).

Has anyone seen this issue before & have any advice how to rectify the issue or have you managed to buy a new housing piece?

Regards
Adam

I have the exact same issues and I also suspect the gear at the bottom. The rotation completely off by 90 happened maybe 3 times in 4 years so it wasn't a big issue (except once when the machine collided with a rack). The misalignment by 15 degrees happens more often, but its mostly on one stylus system and only when you manually rotated the stylus ( when choosing from the list). It never happens during the program. It's weird but that how it works so far for me. The next time the tech is here for maintenance I will try to ask questions.
