Darkening the Lift Plate
After reading this, I decided to minimize reflections off the lift plate by spray painting the lift black. These reflections as well as top layers causing bottom layers to cure means that my first layers get uncontrollably exposed. I reviewed my second calibration cylinders and noted that the first 1 mm of layers were both smaller and had micro-bubbles, possibly due to over-exposure.
5 coats should prevent scratches! I hope this will help the resin adhere better to the plate as well.
