DIY CNC Lead Screw Nut with Anti Backlash

I came up with a simple and effective solution that used a square nut, a spring and two small L brackets. The idea is to ‘pinch’ the spring between the square nut and the lead screw nut, thereby always ‘pushing’ the lead screw away from the square nut (which remains fixed to the lead screw. Change the spring to impact the amount of backlash control.

This will ensure the square nut remains the exact distance from the lead screw nut. The square nut does not need to be “pinched” tightly between the L brackets, but close enough to prevent the nut from turning .
