Comment on Issues with my second resin print

• Okalaydokalay@lemm.ee ⁨1⁩ ⁨year⁩ ago

  I’m unsure as it said it was 73% done but I saw supports and not enough actually printing under the supports…it was weird. But when I went to clean everything, there was a huge circular piece of plastic in the bottom of the vat. So I’m so confused lol

  But you’re right! I’m starting from scratch today with deep cleaning on everything and recalibrating. A new USB would be perfect to match!

    That piece on the FEP sheet is where it let go from the supports when the build plate lifted. More support will probably fix that.

    I always think about what’s happening when I’m doing supports. The resin gets cured on the FEP then the build plate moves up and pulls that layer off the FEP. The part is being pulled by forces in opposite directions so we need to make sure that the part hanging on to the build plate is sufficiently anchored so it’ll pop off the FEP and not off the build plate.

      True, the sticking can be quite the hassle. I personally (carefully) sanded down the metal print plate, as to make it more rough and therefore more sticky, and then bought some new film from fepshop.com which should be less sticky than the original on my Elegoo Mars Pro 1.

      That worked really well, minimizing layer shifts quite a bit and allowing me to use less supports without the print going haywire.
