  • The VAT is constructed with FEP sheet over PDMS, which will last long.  It is the same as Draken vat -  with better quality.  We are making the VAT ourself this time rather than OEM outsource - the FEP sheet used will be best we have tested so far. …
  • How is the vat constructed?  In the Kickstarter, it appears to be the same Form1-style vat used in the Moai.  Is it PDMS with an FEP protective layer like the Draken vat?  Moai users are experiencing a very high failure rate in their PDMS-only vats;…
  • No better teacher than experience. After replacing the PDMS, will you put down another FEP sheet? If so, what kind will you use? I have used Muve3D’s adhesive FEP to re-line a vat before, but that was a pain in the rear. I’ve also been able to re…
  • Everything I've ever read about DLP projectors says that removing that filter will lead to a rapid death for the DLP chip. Good luck.
  • Honestly, with the way that DLP-based printers are evolving and the rapid emergence of LCD printers, this issue with the serial port on the Viewsonic really isn't a problem that anyone should spend a whole lot of effort on solving. Thanks for what …
  • No, not USB-- the blue RS232 cable between the projector and control board. I did a lot of monkeying around and found that once I establish that serial connection properly, it stays active even if I turn off the Draken and shut down CW. I just star…
  • Interesting Joseph. You powered up the printer first, then connected the USB cable? No, I followed your specific directions-- steps 1,2,3 in order. I will try to do some additional testing today.  My projector is not connected to the Draken's pow…
  • Okay, doing the steps above, in order, does not work with my machine. So I shut everything down and unplugged the blue cable from the Draken board. Then, did all the steps again, but after step 6, I plugged the blue cable back into the Draken contr…
  • May I ask if this actually works to improve UV distribution across the build area with the Acer or Viewsonic projectors?  Do you have any before and after examples showing the results of using a mask generated with this program?
  • Honestly, I think the Draken case is totally unsuited for conversion to top-down. The components (z axis, shutter, controller) could be used for top-down printing if you put them into a new framework. To address your sticking problems with the new…
  • Hello,i was scratching my head to stop the leaking, so i think i came up with the dumbest idea, i put some B9 resin in the holes, cured it, and voilà, i just made a print and i have no leak now (it was leaking pretty much).wait to see how much it wi…
  • Joseph, could you tell me if you have found a product that fits to the vat and impeach leaking ? I tried standard silicone caulk, but the acrylic surface was already exposed to resin, so the caulk was not able to stick very well. I have seen no act…
  • That's exactly what my vat looked like when the original silicone started coming out of the corners.
  • I have one vat where the corner joints were poorly done and there was some kind of clear silicone in the gaps (probably the same silicone as used for the vat coating). The silicone started working itself out of the gaps soon after I started using th…
  • Another thing to consider is the pigment concentration of the resin you're using. I read on another printer's support forum about the pigment settling in B9 resins. If the pigment is not vigorously redistributed into the resin before pouring the res…
