I had been tracking down all sorts of fun stuff only to discover that NSTextView is not thread safe. I mean, I guess I shouldn’t be surprised. Going to have to go through and make sure all of my UI elements are updated in the main thread instead of in any sub-threads right now. In fact, I kind of want to push a lot of data updates back into the main thread. I bet this solves all sorts of stupid problem I was having.
At least this explains a great many things.
Between formlabs announcing they’re starting to actually ship product: http://formlabs.com/collections/all
and the new kickstarter from openbeam: http://www.kickstarter.com/projects/ttstam/openbeam-kossel-pro-a-new-type-of-3d-printer
it seems like if you’re wanting to go resin or ABS you have some not-super-expensive high quality options. Good luck to both projects!
