Hello Topsie,

You have made a great job on this CNC project and I´m on the way to get my own one.

I´ve seen that you´ve upload a new file for a longer Z axis. I want to ask you how long should I get the smooth rod and the trapezoidal screw for this new desing.

Having measured the longer components I would think 230mm for the rods and about 240/250 for the screw.  I have 250 rods and 300 screw on order but will need to cut them.
