My second build using TR14 Trapezoidal Acme Ballscrew Leadscrew on all 3 axis and Square 14x3 Trapezoidal Steel Nuts VKM14x3D it is now totally reliable and great to use. for woodworking backlash is not an issue, I also now use car reinforced fuel hose as connectors from motor to leadscrew. also I have had zero problems with the 3.1Nm Nema23 439oz stepper motors and TB6560 Driver.
