First semi-successful print

Well, I finally had a chance to test my printer.
I ran it at .1mm resolution on the Z stage, I still have to adjust the XY resolution since the rabbit came somewhat flat.
The computer video card send the monitor to sleep right in the middle of run, which caused the projector to run at full intensity and creating a diaphragm of cured resin right in the middle of the wabbit.
I used Makerjuice's newest SubSF resin.

It looks like a very successful print! I think once you adjust your settings to not sleep it should be fine. Post more when you can.

Thank you Steve. I'm still practicing and learning.
Here's another print from a 3D scan I made of me and my wife holding hands and using Agisoft Photoscan to capture it.
I am only scratching the surface on the capabilities of my machine, the combination of FEP with passive tilt and the fused quartz vat bottom are working as I expected.
I will be increasing the resolution little by little and use oversampling to get the highest possible quality.
There was a problem with the projector I was using, out of the blue it started overheating and shutting down in the middle of runs. So right now I am converting it to LED and the production of prints will be suspended until I'm done with it.
I want to thank everybody in this forum for their help and support. For providing ideas and always pushing all members toward successful builds.

How is oversampling performed?
Only from what I have read, it appears that LED projectors don't have the power of the mercury lamps, and need more time.
How will you determine what LED projector is best?
I'm considering purchasing the Acer H6510BD. But if a LED can build a layer just as fast as a 3000 lumen machine with high contrast 10000:1, I would be interested in learning more.
Keep the pics coming, they look great, and have you posted build notes of your printer?

You can also use the Anti-Aliasing feature in the slicing profile, works very nice at about 3.5. I believe this does pretty much exactly what you have planed to do but without all the work involved.

I think additional re-sampling choices would be a very popular feature. As a lot of effort by many people is put into achieving the ideal surface finish.
