@azplasma That is a Nylon issue where it warps the plate right off the magnetic bed. When this happens, pull forces up to 43,000 psi can be exerted on the build plate.
To solve this issue, you need to adhere a new layerlock sheet to something magnetic other than spring steel. I suggest purchasing a custom cut galvinized steel sheet 0.100" thick. This will have even greater adhesion to the magnetic base and will not bend from warping.
