I’m having repeated issues with a 3rd party resin sticking to the tank FEP (I assume the LT tanks are FEP film?). When I use a new bottle of resin and a new tank, I get a few good prints. After a few prints I get failures, and now I can’t seem to get anything to work.
I’m using open mode, and if I use one of the faster profiles like White V1, my prints either break off part way through, or pull off the platform. If I use something like Clear V2 or Gray V2, it sticks to the build platform, but also sticks to the FEP. It’s obviously taxing the Form2, making loud banging noises and barely getting the print to break loose. I sometimes get successful prints, but I get a lot of junk stuck in the print that looks like torn off layers.
So here’s my question - what can I do to make the peel easier? When I hear the loud banging noise and see what looks like missed stepper motor steps, am I hurting the machine?
I’m using 3dresyns, and I have light blocker and fine tuner, but neither seem to help. I’ve also used an external heater to make sure it’s warm 25-30 C. It still seems to be a choice between tear-offs and extreme sticking to the FEP.
