Smart thinking on the gauge tabs for the back-stop - I thought they were for the red braces in post #41. What have you got under your V-rollers? Look a little small, the roller may "wobble" a bit...

Jack, dust hoses for twin Z's are a major headache - they have to fight for space with the y-motor or with the y-cable chain. (They cannot pass outside the y-car. between the gantry...
