I got some custom made bellows from AliExpress for the Y rails and the gantry. I've made something to cover the bottom of the Z axis rails up from some flat rubber sheet:

And I've made a lightweight polycarbonate enclosure to try and catch some of the chips. It just sits in some aluminium rails fixed to the sides. I wanted something that would be easy to remove to give good access for working on the table:

This is as far as I've got as of today. I've got the stepper drivers hooked up to an Arduino running GRBL, and the machine moves with gcode from Universal Gcode Sender on a laptop. I made a short video of it working here https://www.youtube.com/watch?v=I5fmULRv4vA

So now I'm waiting for a spindle to come from China, and a Mesa 7i96 to come from the USA. I want to try and get the thing working with linuxcnc in the end. GRBL does work but it seems to have quite a few limitations. On the other hand it was almost free!
