Extended Z-Axis Work Envelope for the Mini Milling Machine

[Great Ideas Catalogue]

Yes, I agree with you. It will be less rigid should I mill a very large high workpiece that requires the head to be lifted higher. I made the extension primarily to enable tool changes. However, I have also improve rigidity by adding an exoskeleton that makes the column significantly more rigid.

Have a look at with my Exoskeleton video.
