The band broke up, and I'm thinking about the dark side.

I keep snapping the 'O'-rings on the OpenFlexure stage, probably because I'm pushing the range of movement more than the average microscope user. That's going to have to change, probably using anti-backlash nuts like the old Darwin printer's Z stage. There are a few other things I want to hack about: Proper motor mounts, extra platforms and attachment points, new flexures, better gearing, more access the the mechanism, cable guides etc. but it's going to have to wait until I've finished presenting at EverythingOpen. Once I've decompressed from that trip I'll be able to focus on ╬╝RepRap properly. I have some photosensitive resin ready for dip-pen tests too, but blowed if I can find my stash of UV LEDs anywhere.

I plan on having a darkened resin reservoir on the slide, and illuminating from below. This will avoid having to shield the probe or the resin reservoir during UV exposure cycles. Hopefully cheap soda lime glass slides will let enough UV through.
