The printer looks great Andy. I'm currently designing a delta printer which shares several characteristics with the Cherry Pi and I was just in the process of re-designing my base to contain all the electronics too. If I understand correctly, the second revision has become slightly shorter and wider. Is that down to stability issues or down to a desired print shape?
I'm also using the 250mm mirror as a print surface, but currently have 750mm extruded aluminium uprights.
The original had 800mm extrusion for the towers and it really wobbles about at high print speeds. That can only reduce quality. I rarely print anything over about 80mm tall so losing a 100mm of height wasn't an issue. It was also configured for a 300mm diameter build plate. Version 2 has 600mm towers but, as there is no heated bed, no separate limit switch mounts and shorter delta rods it still has 270mm build height. I also went for a smaller build plate as 250mm mirrors are easy to source and cheap plus the proportions look right.
I had to go for a 6A psu rather than a 20A in order to fit it under the bed. You can see from the photos that it's a tight squeeze. As I don't need a heated bed for CP II it wasn't an issue and as a bonus is much cheaper.
