I built a MPCNC last year. I was not successful in incorporating this machine into my shop. i encountered issues in the beginning printing pieces for the wrong size tubing, then purchasing carbon fiber tubes that were 1 in, because I couldn't find a tubing distributor that wouldn't charge me a custom order for 1 in.
The build was interesting but the machine function just sucked.
This is my 2nd attempt. maybe this new design will find it's way into my shop. Going to build smaller footprint this time
Printed pieces for 3/4 in conduit from s. florida hardware store
