OK, mine is done- total build time 6:45. I had the benefit of mhackney's build thread, plus prior experience in toy and furniture building...
Some post-build thoughts:
1. The door latch would be better if it was magnetic. I'm going to design one and put it out on thingiverse.
2. I'm concerned that there are some light leaks from the back panel around the nuts, and at several places where there are gaps in panels (such as at the top of the door). I plan on using some aluminum HVAC tape to fix those places. There is also a lot of light leakage around the door and the nut slots in the door.
3. I would have built the z stage before putting the extrusion into the chassis - put extrusion into top, then through z stage, bottom, etc. Leave the antibacklash part for later. Don't mount the motor until you add the threaded rod into the z stage. My kit came with three tall nuts - two for the z stage and I used the other as a locknut at the motor coupler -no loctite needed.
4. In looking at the build platform alignment to the bottom of the petri dish, it is clear that the surfaces are not parallel. A solution to this might be to include a ball and socket joint in the aluminum build platform that would allow for immediate adjustment, then with a lock screw, set it in place. Kinda like a tripod mount upside down...
5. As has been noted before, the holes for mounting the arduino are wrong. To save time, I used some special double-sided mounting tape with some very strong adhesion.
As I don't have a suitable build vat (my trial fit petri dish is plastic) I'll have to wait to try a build. But I do have the silicone filler for the window, some fresh resin, the projector, computer and software to get it working. So has anybody heard how or if we are getting one??
