Reply To: Ball screw Z axis?



What is the main purpose of changing all of this? The only real benefit would be to increase the z axis speed, but you could possibly sacrifice resolution (less steps per rev).

Increasing the distance of the tool holders decreases design strength, that is pretty expensive.

When I chose all the parts I did my best to consider cost vs benefit. I haven’t had any issues with the threaded rod, so for me it was an easy choice.
