I've said this several times now but there is very little difference between the two methods in real world use depending on gantry design. The type and design of machine/gantry is a better selector for which method is best.
Hi JAZZCNC.

I will study this one,

I Always thought mounting the horizontal and vertical bearingblocks on the 4 corners of a single piece of rigid plate would always beat any other setup and would result in the most stif setup.

No influense from flex there.

The flex in the moving zplate could be made less by putting on 2 big motor mounts using round type spindle motormounts.

In this case the spindle motor is square which makes that one a bit easier.

I would have thought having a bigger lumb of metal (rail rizers, square rails, z plate, motor mounts, bolted to the spindle would lessen the vibrations.


So I have something to think about.

It is good to have al these experienced guys here.


Grtz Bert.
