Anti-backlash assembly

[martinw]

A lot of the XYZ router designs have a torsion box below the X axis table to hold the gantry sides together and make them more rigid. The torsion boxes are often several inches wide. This may be a daft idea, but it would be possible to mount the two halves of the X axis anti-backlash nut on either side of the torsion box (ie several inches apart). The AB assembly would then effectively hold the X axis shaft in line and so reduce any tendency of the shaft to whip.

I would be grateful for any feed-back on this.

Thats is exactly what i did on my CNC Model 2006 R-2, it did help in keeping the leadscrew totally straight and helped to prevent any whipping although everything on my machine is perfectly ligned up allready.

Dear Joe,

I do apologise! I have spent hours reading your threads and studying your drawings and completely missed the fact that that is what you do. Maybe it wasn't such a daft idea!

Thank-you
