First DLP printer questions

Hi, I'm trying to build a DLP 3D printer this year as my Christmas present to myself (I'll probably finish it by march) and I've got just a few question I'd like to ask if anyone has any experience or recommendations: 1) Is a nema 17 27:1 geared stepper motor okay for a z axis? I've read people have...

Re: Simple Light control

Re: Simple Light control

Well that isn't exactly the lens I have but it has the same specs on paper. Anyway my LCD is unfortunately multicolored. I could not find anything monochrome at that size that had a reasonable pixel pitch, or wasn't non-graphic, was a very small OLED, or from eBay and kind of questionable. You know ...

Re: Simple Light control

Generic 20W LED, 600ma 32-34 V, and a focusing lens. Its basically the same time as you'd find on ebay. Here's either it or a similar one on ebay: http://www.ebay.ca/itm/221420907620?var=520297371649&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649, and a similar driver: http://www.ebay.ca...

Re: Simple Light control

OK, I got a 20w UV LED, I think that should be enough. Any tips as to how to modify the firmware to get this to work?
