Cew, regarding focusing, I discovered after emptying out the vat that I could faintly see text projected directly on the bottom of the vat this time, without adding anything. 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!Statistics: Posted by Mattasmack — Sun Feb 28, 2016 9:48 pm
