I’ve come down to these sizes:
.25 - .3 for smaller pieces at 25um though I’ve found the .25 to be more fickle in terms of consistency
.3 - .35 for 50um .35 to be on the safer side
.35 - .4 for 100um
Though one caveat is that each piece seem to require more supports especially around circular object. Auto-generation seems to be less accurate in having successful prints compared to the form 2. I’m still doing quite a bit of tests to fine tune everything and the numbers may go down some, but I get a bit anxious on having to deal with failed prints in the tray as some pieces do not want to come off.
Extra tip, reboot after every print, not sure if it’s a problem with my resin cartridge but I’ve had my prints double in print time and a reboot fixed the problem.
