  • How does it work then when printing over the entire projection area? That is the real test of whether your mask works properly.
  • Great video and what a good mod!  It is easy enough to do and it doesn't require you to open up the projector body other than if you were replacing the light bulb. I like the purple glow. I should look into picking up some of that filter glass to se…
  • Nice! Any photos to share on the forum? Are there any concerns about importing into the US?
  • I will be very interested in how that works. Almost all visible light will be blocked, so how that will look at the vat will be very interesting. I wish there was a spectographic reading of the lamp in these projectors to get an idea of just how muc…
  • 1/3 the time is a nice improvement. What resin and what were the before and after times for comparison? If you can't get the heat out, you will shatter interior lenses. If you can cut glass, get your hands on what they call a hot mirror and cut it t…
  • Okay, I see now. The trigger I saw was that if the projector was connected to the control board and the controller was not powered, it would not work. If I pulled power from the projector, or in your case, disconnect the blue serial cable, and turn …
  • Okay, so the different you made is that you did not plug the USB back in step 2 but waited until step 6? Regarding your power config, I don't think the power supply to the projector is the issue, but the power supply in the Draken feeds 12V to the c…
  • Interesting Joseph. You powered up the printer first, then connected the USB cable?  From what I have seen, if you power on the printer, the controller board will get powered up from the supply in the Draken, not from the PC. I wonder if that might …
  • I've done some testing with a Viewsonic projector on loan to me and have a work around I'd like people to try. This assumes the blue serial cable is connected to the Draken and your Viewsonic PJD7820HD projector and you are using my latest firmware …
  • My take is that it is more of a greyscale generator using empirical observation of a test run than direct light measurement or attempting to make a mask using a picture of the light output. I think you need to run it a couple of times to dial in the…
  • I have no idea what is going on with that configuration then. :-\ Without having a projector of my own to experiment with, I will have to leave Viewsonic support to someone else.
  • @nicolas take some pictures and if you want, post them to a new thread in the support section.  I need visuals to help me diagnose your problem. :-D
