I have a correction. I did break off my color wheel because it was too difficult to get to the screws that held the wheel in place.
If you need to break the color wheel, just be careful to make sure none of the small glass particles get in the light path. You will end up with little speckles in your image. I was able to clean mine up pretty good and don't think it's effecting my prints at all.
My Mitsubishi projector was only 150.00 on ebay so I wasn't too worried about messing it up. Not like with the BenQ.
Now with the BenQ, the color wheel was easy to unbolt and move to the other side and tuck away while keeping the connection in tact.

I believe there is only one screw holding the lens from moving/rotating at least that is what I think I am seeing at about 2:40 sec into this video.
I'm sure I'll have many more questions on my build, really glad I found this place and such a helpful group.
Thanks

I also learned, at great cost, that you do not have to remove the color wheel or any other filters to get good exposure results. I ruined a brand new $1000 BenQ HD projector when I removed these filters. I completely burned up the light tunnel and then proceeded to melt the lens mount that is between the light tunnel and DMD chamber.
At first, I was out 1000.00. I decided to order another BenQ 1080ST. Once I recieved the new projector, I chickened out and sent it back for fear of ruining another.
On the bright side... Fedex misplaced the shipment on the way back to Amazon. SO... Fedex then reimbursed me for the shipping screw up (Luckily I had the projector insured for 1000.00) So I got 1000.00 back from Fedex. THEN....Amazon finally got the projector from Fedex. Since it was past the 30 days on the return, I only got 80% refunded back. SO I got 800.00 from Amazon.
So, in the end, I was only out 200.00 and I still have my destroyed BenQ projector. I'm sure I could get back my 200.00 if I sold the lamp on Ebay. They go for about that much.

Most lens assemblies are bolted to the DMD housing with 4 small screws.
That should be the only mod you need to do on the projector.

I'm just in the process of getting parts together for my first SLA based build, I've built a few Deltabots and a CNC router so this was the next on the "to do" list.
Recently replaced my home theater projector and thought I might be able to use my old projector for this project, if not I am open to buying one just not sure exactly which would be best. The one I have is a Optoma HD65
Would this work Ok or would I just be better off getting a better model? I have pretty much everything else kicking around other than the vat coating and resin which I will be ordering this weekend. If anyone has any suggestions or info they can share please feel free.
Thanks
Clinton
