Design Thoughts

Posted: January 16, 2013 by kwood94xj in CNC

Looking into ways to link the motors to the X,Y,Z axises. Originally thinking to use 3/8-12 stainless threaded rod and 2 nuts to reduce backlash. It should work but it may wear out quickly. Acme threaded rod is much better. DumpsterCNC carries anti backlash nuts at a reasonable price. The rod itself is on the pricey side at $20/ft. so we may start with SS threaded rod and upgrade to the acme rod later.
