I have a standard lead screw 12x12 machine. What is the specification of the Standard lead screw? Not the F8 upgrade. The Zen forums are down, and the wiki didn't note the specification. Just trying to source an anti-backlash nut.

If I remember correctly (it’s been a while) I believe they are 8mm x 1.25mm

Re: Standard Zen Lead Screw size/specs?
I have a Zen clone, it came with M8x1.25 all-thread originally. Replacing those with T8 trapezoidal screws was one of the best things I've done to the machine.
As for the anti-backlash nuts, it's very easy to make your own if you have at least somewhat working CNC machine. It uses two standard M8 nuts.
