Z Axis appraisal please

[EddyCurrent]

Ah ah I find this hilarious.!! . . . For some reason you don't like the screw at rear but yet your happy with the rear plate extending down below gantry and flapping about seriously weakening and compromising the quality of finish.?

I mentioned this in my post because I knew it was crap but I'm changing it now.

Think about the machine your building not what some spread sheet that somebody who's never probably built a CNC machine predicts is the optimum location, Or from looking at some poorly built machine who's getting less than expected results then blaming there crappy build quality on design style.

I agree but I like the look of this design better anyway

Your insistence on keeping Z axis slim and low is seriously compromising the machine.!! . . . Front or rear screw no matter but this Z axis is wrong.
Lift the bearings and rear plate so they are supported by the gantry other wise the back plate will flex under cutting forces.!

Same as point 1

What happened was I was concentrating on the top bit and forgot about the overhang until I posted the pics and saw it.
Also moving it to a Build Log next.

Thanks for comments.
