RP 'ers,,

The extra 0.3mm extra Z curing occurs on the first supported layer of
every build. This is because the laser over-shoots the first layer as
their is no cured material underneath. Subsequent layers consist of
liquid resin and already cured resin so the depth is easily defined and
maintained. As I am aware of their is no current solution for this

It would be interesting to know if one exists!!
