Problem with supports not printing

[cliffyk]

I have read of some using Rain X and the like to treat the FEP, and though as intuitive as it sounds, it is not something i have tried or could recommend as it has to become a contaminant between the first and subsequent layers of the model. Declining in quantity certainly, but a contaminant nonetheless.

I have and do use a very thin film of silicone mould release between he FEP and the LCD (I spray a bit on a micro-fibre cloth and wipe both surfaces lightly) to block any tendency of the two to adhere to one another, which would prevent the FEP from flexing upward during the layer detachment operation.
