That sounds good...

Maybe it won't be so critical to offset the Y in that case as I'll be losing the power feed from the end and all the space it takes up. I could retain the pulley drive and have the stepper on the same plane but just offset it towards the rear a bit, losing one of the pulley thicknesses from the equation.

I might have to draw my ideas up in Fusion tonight, I have the saddle modelled up already and a picture speaks more words after all, but then I might just measure up again get the screws ordered and take it from there.
