Right now I am working on a 2 part detachable build platform with holes drilled into it. This should solve my issue of destroying the platform trying to get the parts off! Now I will just pull of the platform and put it straight into an alcohol bath - this will keep my build plate clean and allow for much easier part removal. Also I was printing large flat parts directly to the bed which made them even harder to remove. I will now be experimenting more with support structures.

I think it would be great to start a thread with resin / projector cure times if there isn't already one. If there is one someone let me know, otherwise I'll go ahead and start one. Cure times can be a bit frustrating when first setting up when also dealing with a bunch of other things to figure out.

How about build supports for all you top-down people out there? I've seen a lot of people having issues with large holes on the bottoms of their prints. For me I am going to be printing objects with large flat bottoms pretty often. I'm not there yet but I am wondering how well this will work using build supports.

Vaughn thanks for your input - we have a very similar set up and I've been following your thread and posts - good stuff keep it up!

For leveling on top down it's a trial and error. Also, i build a layer with the build plate just above the resin level (manually squirt clear resin onto the build plate) and then let it start the build cycle. This requires that all parts be supported so that the build discrepancy (1 or 2mm) gets absorbed into the support structure.
