    Hi Dennys,
    Thank you so much for your videos! You're a wealth of information and I can't tell you how appreciative I am for them. I am learning so much from you. I would like to know if this test should be done after calibrating normal exposure times, or should it be done before calculating normal exposure time? Thanks for your time, and again, thank you for sharing your knowledge to the rest of us.

    Thanks for this vid! I've run probably a dozen bottom exposure tests, get it dialled in perfectly, and then I go to do a print and I get adhesion issues. Not a levelling issue as I run levelling tests first, not a heat issue as I keep a close eye on that. The only thing I can think of is that the WhamBam plate is causing problems, even after the extensive sanding I've done? It's very strange, I'm running out of theories.

    • @hardyroachvids4021

      The bottom exposure test comes out fine as low as 25s, and yet I'm still getting adhesion issues at 40s. It's bizarre, and I've run down the other variables.

    Hello Dennys!! Is it necessary to sand/rough up the build plate right out of the box before using for the first time? I've been following your vids for a couple weeks now and have learned a lot from you. I'm brand new to the 3d printing world and appreciate everything you do. Keep up the great work.

    • @wangdennys
      @wangdennys  2 роки тому +4

      What printer are you using?
      Depends on the build plate.
      If it sand blastes surface, no need to.
      If it just smooth stainless steel surface, then need sanding.

    I ran the bottom exposure test and I can go down to 10s on my mono 4k without a fail, however when I tried to print your anti-aliasing test I couldn't get it to stick until 17s. When I printed the mcbeer articulated dragon it doesn't print properly until around 25s. Since I've seen you print both these models, did you use the lowest value this test gave you or do you change your bottom exposure depending on the object and use these results from the test as a baseline?
    btw I also level in the vat and my build plate is level according to your leveling test. Sanded it as well.

    Hello Dennys, I got a question: My prints are failing with settings that yielded PERFECT results before. I use the mighty 8k. Some days ago, the prints started to stick to the fep and fail. is the fep broken? i used some rain repellent on it, even tried silicone spray. nothing helped. it is not too scratched or deformed, and it is still mostly clear. some areas of the build plate still print fine. and they stick to the plate very well. i re-calibrated and leveled the plate. nothing helped. do you have an idea what i can do? thank you for your content.

    • @DisgruntledPigumon
      @DisgruntledPigumon Рік тому

      Room temperature, resin temperature, resin age, LED age.. could all cause problems there. If you have a ball joint build plate, there’s always the chance you twisted it or stripped the bolts so you can’t get a strong level grip anymore.
      Also, never use those Teflon sprays. It’ll contaminate your resin and you might actually make your build plate more slippery.

    How do you sand your build plate. I discovered a huge lake (concave) in the middle of my build plate. Sanding it flat has not been easy, I think I have a rounding error near the edge.

    Hello,
    i have tried your method and run into a Problem. I use a 0.15mm thic paper for leveling and my FEP is also 0.15 mm thic. My LCD is sligthly risen above the housing so i dont have to add a distance for the space betwwen fep and lcd. Before i never had a Problem but because i made a mistake i had to refurbish my buildplate and ordered a new one for the instance that my repair attempt failed. It worked very well and now i have 2 Buildplates that should work fine.
    But since i leveled with these technike i got liddle fins on one or two sides of the squares which are so thin, that they break appart when removed from the buildplate. But since they first appeard i cant get rid of them. Did someone here have seen something like that and can tell me what causes this Problem?
    My resin settings are dialed in pretty well so i think its not the curing time. Also regardless if i lower or elevate my 0 Offset by 0.1 or 0.2 mm the Problem gets worse if i elevate and if i lower sometimes not all Squares print.
    Printer Elegoo Mars Pro.
