Sturdy and Fast all Steel CNC , my first build

[Boyan Silyavski]

Today after whole day drawing, considering, redrawing, considering... designed the ball screw assembly on Y/ the long axis that moves the gantry/.

I wanted it sturdy, compact, at the right place and most of all easy to rectify and assemble. Following step by step. Still have not figured the belt length, so a minor correction maybe tomorrow. Other challenge was how to keep the working distance at maximum and at the same time ball screw length minimal.

Designed the hard stops with threaded holes for proximity sensors. A bit overbuild but for sure there will be crashes as the guy is a new to CNC.

Some pictures. Have to finish the design this weekend in order to buy the rails, ball screws and order the laser cut pieces.
