Im about to have a crack at a router/mill out of ITEM extrusions myself.
Nice work.
How did you align the extrusions accurately?
The brackets I have get it close but not close enough. I have a dial indicator but Im down a straight edge. Will have to get one soon.
I might be wrong about this but arent the rails on your gantry on the wrong side?
I thought the cutting head should be as close to above the gantry's bearings as possible to minimise the leverage forces on the bearings, (Moment B in the diagram).
