So it looks like the film is getting a little cloudy; I don't know if that's a problem but it certainly made focusing easier this time. I did try using a magnifying lens as you recommended and that helped.

That's good to hear about the calibration block! I did try angling it up and putting it on supports and it printed fine that way; I was just concerned that its curling when laid flat meant I had something set up wrong.

Do you have a picture or .stl handy for your modified arm spacer? I'm using a hollow platform and the resin draining from inside is indeed a pain. I can turn the platform 90 degrees and tilt it back as I loosen the thumbscrew to get the resin inside the platform to drain back into the vat, but then resin dripping off the print itself tends to hit the projector.

Regarding overhangs, I'm not concerned so much about design rules for making models, as I am about optimizing machine settings. I did try turning down lift speed and added a bit extra delay at the top of the lift and after the return, and that seemed to help some. Thanks to both of you for the Meshmixer recommendation. I haven't looked at it since trying it once or twice to prepare parts for printing on my old FDM printer; I guess it's time to give it another look!

Focus? I used a piece of wet tissue in the dish. If you use the red calibration grid in creation workshop it is not too bright and easy to work with. Depending on your eye sight you may also want to use a lense or usb microscope to fine tune the focus at higher resolutions.

Calibration block curling? Yes I had the same problem. The following can help reduce this issue; hollowing to a wall thickness of ~1mm, low shrinkage resin such as B9 black, tilting the part and using full supports.

Resin dripping? The new solid build platforms reduce this a lot. With the older hollow platform I modified the build platform arm spacer stl so that the platform could be tilted for draining into the dish. You can also add a line of gcode to automatically elevate the part clear of the resin at the end of the build. However I keep a stack of paper towels next to the printer..

Design rules for overhangs? Formlabs have a design rule pdf that is quite useful. Meshmixer and autodesk print studio can usefully automatically generate most supports for overhangs if you use the 'ember' dlp printer settings. If you look closely at your prints you can increase exposure levels and lower lift or return speeds (eg 70mm/min) to help a bit.
