There is no reason you cannot used a toothed belt and pulley at the other end.
As long as the lead screw backlash is taken out somehow. On my Gingery Lathe
I have two ball thrust bearings on either side of the lead screw bushing
taking out the backlash. At the tail stock end a toothed

This is exactly the insight I was looking for now I understand why the
conventional mounting is always with the servo at the head stock end.

When it comes to flexing and bending, think about the bed too. If the servo
motor and pullies are mounted at the tailstock end, then the bed will carry the
reaction forces and see exactly the same tension and “twist” force as the
screw. But if the motor is mounted at the headstock end the bed
Thank you Leonardo,
That makes me feel better 2 to 1 reduction will fit easily in the
space available.
I should have been a bit more clear both ends of the Z axis ball screw
will be supported by ball bearings in pillow blocks. The head stock end
will have two bearings back to back with a

What I am thinking is mounting the fixed end
Machines often have both ends fixed and the assembly preloaded by applying
tension to the screw.

LinuxCNC 2.9.2 has been released. This is a bugfix release, with the
most obvious change being that run-from-line in the Axis interface
should now be working again.
Packages have been prepared for:
Buster - uspace - amd64 (PC) armhf (Pi) arm64 (Pi with 64-bit kernels)
Buster - RTAI - amd64
Hello Linden,
For your first question. I would mount the motor on a fixed end just to be
sure, so that would lead you to make both ends fixed. I guess you can mount
your servo on a non fixed end if the machine is not going to be used for
heavy cuts on hard materials but I would go the extra
