Problem with supports not printing

[cliffyk]

I would try increasing the exposure times by 20% to 25%, perhaps a tad more--IMHO Chitubox's default exposures for the M2P configuration are overly optimistic. The M2P does have a higher wattage¹ curing lamp, but not THAT much more powerful...

---------------------------------------------------------
¹ - I have seen it claimed to be 50 W; how they do that, and power the other stuff (mobo, fan, stepper motor and LCD) too, with a 60 W "wall wart" is a mystery to me. Also, I realize the monochrome LCD is more efficient--but again not THAT much more efficient.

BTW, my plain ol' Mars printer draws an additional 40 W when the LEDs turn on...
