Any ideas as to what I’m doing wrong?

This sphere has a ridge on it, and I’ve had miniatures come out with the base to be slightly offset giving a bit of a ridge.

I’m using a Halot One, lychee Slicer, and Anycubic Water Wash resin.

    Suction cupping causes the print to rip from the build plate/supports, it wouldn’t cause this. Especially since it continues along as if a few layers were cut out of the file, which just isn’t something caused by suction cupping. It would essentially need to be stuck to the FEP to such an extreme degree that the stepper motor is unable to move.

      It can cause both, actually. And it continues along, because it eventually gets up high enough in layers that the additional lift manages to break the suction effect. Finally allowing the resin to drop out of the top of the model and for it to cease happening. If the FEP film isn’t tight enough, or has loosened up due to wear, it absolutely can follow the print upwards without disconnecting for a few layers, without pulling the print off of the build plate.

      I, quite literally, run one of the few professional shop for repairing FDM and Resin based printers in the USA and have 12 years of experience in the field; engineering systems, designing products, and even had a few successful 3D printer kickstarters. Sure - without looking at it, I could be missing something here, but I highly doubt it.

        Suction cupping could be a possibility on the sphere, it does not explain why I had ridges on miniature prints.

        A loose FEP wouldn’t cause the print to essentially perfectly skip over multiple layers. Once the FEP finally releases, there would be multiple layers missing, resulting in a very gloppy thick layer, or the remaining layers printing directly on the FEP.

        I can’t think of any situation a loose FEP could result in the above image without at the very least one “extremely large” layer.

        Not to mention, the FEP wouldn’t suddenly tighten, meaning you’d have the same issue over and over.
