Trapezoidal leads screw in the 3D printer, solution of axial backlash

Features:
- useing the leads screw in raw unmodified form
- only two radial bearing and two axial bearing per axis
- the price is up to $ 15 per axis

Solutions for use trapezoidal leads screw in the Y axis with a 3D printer. The proposal is optimized for AL profiles 30x30mm.The problem with springing belt and alia by drawbacks can be solved by using a trapezoidal screw.Speeds can then be catch up with using 24V for the steps motors, which then can be run at higher speeds with the same torq
