Hi All, apologies for the late response with this, but I discovered several issues with the klicky setup and in the end I ditched the whole configuration and went with a BLTouch sensor, everything you guys posted on this thread helped me sort it out and I have now got a fully functioning Voron XL!! - I want to do some additional tweaks around load and unload and some panels to enclose the whole unit but it prints beautifully now and the bed compensation is spot on.
So many thanks everyone I would not of got it sorted without your input on this issues and the other control related posts
