Projector Mod for LittleRP Success!
Posted: Mon Dec 19, 2016 5:42 pm
I just finished modding my Veiwsonic PJD7820HD projector for my Little RP.
As we all know, to speed up cure time with a projector you have to remove the color wheel, or remove the UV filter, or both. Since I didn't feel like disassembling this thing beyond removing its case and having to build blinds to protect from the UV emissions, I opted for the former.
The wheel has to be connected, otherwise the printer won't turn on. Rather than breaking the colored glass off the wheel, I decided to mount it elsewhere inside the projector. It just seemed rather dumb to break a $60+ part, and I would like to have the option of using this thing as a normal projector.
I simply made a new bracket out of a strip of metal (cut from scrap), removed the adjustable foot thing, drilled a hole into the bottom plastic, and bolted everything in.
I have yet to make a test print, but it turned on with no problem and projected a perfectly clear black and white image. No odd noises, no vibration, no nothing. Just the hum of the fans.
This should cut my print times to a third of what it was before.
