Comments sought on new build: A CNC Router for RC Gliders and Planes

[njhussey]

Just swapped the supported round rail for linear rails and also turned the Z axis 180° so the chips will not collect on the ballscrew or mount. I've also dropped the Z axis stepper behind the upright and it will be connected by belt (1605 with 1:1 connection to the stepper) It will have a cover over/round it and I'll look at making a cover for the rest of the Z axis. I've now gained 50mm of Z travel so total travel now 200mm. For the Z axis rail mounts I've had to raise them on some 20mm plate strips to get the 1605 ballscrew in there. Will have to make a low profile mount but that's the least of my worries!

Changing the X axis to single stepper and belt drive, yet to work out the finer details of supporting/tensioning pulleys.

Anything that you peeps can see that could do with altering? I've tried to keep most of the plates with straight edges so I can cut them myself. the only ones I've left with curves and machining are the Y axis end plates. I could always make these with straight edges and no machining!

The actual router frame is removable from the upright frame so that If so wished it can be put on a flat surface if ever required. Also for working on (pouring epoxy resin for levelling the rails for example) it will be easier than trying to tip the whole frame.
