Ive been printing terrain and learning on a modded Ender 3 Pro I got broken and got working.  Took a lot of research to get it up and running and its consistently printing good quality terrain pieces now.  I acquired a Mars 2 that wouldnt power on. Simple fix, loose ribbon cable, and replaced a broken usb port.   I felt confident in my filament printing abilities to jump into resin.  I was wrong......  Im using Lychee with a default setting for Mars 2.  My test rook came out a little thin and brittle.  Was really stuck to the plate but came off with a little effort.  I thought it was good enough to print a mini from some hash files I found on Reddit.   It was a complete failure.  I printed in pieces with thin supports.   The main body, only the torso printed not the legs,  the back back and hoses (it was a flamestorme aggressor)  didnt print at all. Or if they did print it didnt stick because I had some forms in the resin tank that kind off looked like the shape of something.    So now im watching Youtube videos and learning about exposure times and such.  I think the issue was the exposure time was too short (defualt setting was burn in layer 35s and normal layers 2s)  I found a guys video with a cool calibration chip im going to use, but any other tips for starting and learning resin printing from this community would be appreciated since im mostly going to be printing 40k minis for personal use.  

Resin im using is Elegoo Standard Grey

 Would Chitubox be a better program to use?  I use Ultimaker for filament prints and like its interface.
