  • 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'd just use the putty knife or one of those plastic blade scrapers with the removable blades. Also, the resins I use do not bond to the build plate like crazy glue. I dunno what would happen to MDF after it gets saturated with resin like that. I'd …
