Hi all, new to the forum. I recently purchased a form 3 and was using the standard Grey. I printed a few small object about 1.5” x 1.5” x 1.5” and it took about 3 hours and it came out great. I completed several prints and used all my standard grey. I switched to 1500 tough and changes the tray. 2 strange things occurred

- i got a warning that my tray was no compatible with the resin type (i clicked continue)

- then my print time jumped from 3 hours to 18 hours. I removed one of the objects and the print time is 15 hour and 4 minutes?!?!

Anyone know what’s going on here? Sorry if this has been covered, i skimmed The forums and saw a thread “wildly off print time” but it was a sighting different situation. Any advice is greatly appreciated.
