Strange Noises On Y Axis Identified And Fixed
We knew there was something up with the Y axis. Here's Exhibit A in centre frame:
That little hook-like protuberance is what holds the anti-backlash bands on. Those lugs are optimistically thin, and under load seem to bend out. I've strengthened them and added some clearance inside the frame in case they bend again anyway. Made a bit more room in there for the bands too.
While I had to take the damn thing apart I took the opportunity to replace the Y Flexure with a solid beam rather than the wibbly flexible thing that V0.04 needed. Testing that before Githubbing it.
There's more stuff to come on problems with curing UV resin properly, but we'll get there after I've done a few more tests on it.
The colour scheme is definitely taking on a festive air.
