Got the Y axis screws synchronised and belt fitted tonight, fine-tuned the ballscrew nut brackets and the bottom end is just about done, threw the bed and over-bed on for a photo...

The 15mm alu over-bed will drilled/tapped for mounting studs etc, it's a little shorter than i would like and cost me about 50mm of Y travel but it will do ok for a while.

Just waiting for some alu bar to arrive for the X axis motor mount and we will be wiring up for motion testing :)
