I’m curious to know if anyone has any settings advice for running Formlabs Color Resin v5 on a Saturn 4 Ultra 16k printer ?? I’m going to try it when the resin arrives, just curious if anyone has some basic settings start points?  
The Saturn 4 Ultra 16k has a REALLY hot screen. My .05 layers had to be tuned WAY down to about 1.5 - 1.7 sec per layer. the recommended 2.7sec was way too long.

Laser (SLA) resins and MSLA resins have different activation / polymerization properties. I would not recommend using them in the wrong machines.
