Thank you for the reply.
I apologize to change the subject. I wasn't my intention, I have had a

If you can match the supplier, then possibly. Otherwise there is
almost no chance of getting a good match.

That sounds about right for 10 degrees of play in the screw.

For Rick :
A problem identified, thank you Rick.
I will replace cables.
You changed the power and encoder?
Given the color and the type of cable, I do not think this is the original
cable.
For power, did you use shielded cable?
What section did you use
Andy:
I have another problem:
You are seeing pretty much exactly the same issues that I was having
with both of my machines, you have the A2100 control, and that was the
fault that I was getting on my machine, before I replaced the cables.
That is definitely physical damage on the X axis cable, but the damage I

I don't think you can necessarily say that with that test.

This 3rd picture seems to show you indicating you can rock
the screw forward/backward by 10 degrees. This would seem
to indicate wear and looseness in the ballnut, or possibly
in
No we have never had any issues like this, that is why I would be
looking at the mounting of the physical ball nut and mounting block, It
doesn't appear to have any taper pins, just 4 bolts to attach the
mounting block the the casting, and 4 bolts to mount the cartridge into
the mounting
For everyone,
Thank you I'll watch carefully.

Have you ever had this problem with your Sabre 750 ?

It doesn't look likely to be.
The first place I would be looking would be at the screw thrust
bearings, though.

If you can't fix it, you don't own it.
If this is any help, here is a link to a copy of our Sabre 750 Z axis
ball screw layout, your machine looks identical to our machine.

Is the ball nut mounting block solidly attached to the back of the main

Don't ignore the possibility that the backlash/ slack might be in the

Depending on the style of the ball-nut, it might be possible to adjust
the backlash.
