Baby CNC update

A minor update on the smaller CNC I'm building with the larger one...

Gantry parts are nearly all cut and assembled. The gantry is only loosely resting on the cart at the moment.

This shows the cut outs for the cart parts, the notch for the back boards, the holes for the steel rods.

On this side you can see the extra board that is used to adjust the "squareness" of the rails. (And also some of the scarring that is a result of the 'safe' height not being so safe....)

This little project is making it painfully clear that the big machine needs calibration, overhaul, etc. The holes are always too small, the edges are not 100% square and the big machine constantly stalls and I have to try and save the job...
