Ender 3 S1 Plus

Should I install Klipper? Mainsail or Fluidd? Or leave it stock? Or sell and upgrade to a newer printer?

If I keep it I’d like to eventually get a laser module How hard is it to revert from klipper back to stock?

I recently got an ender 3 s1 plus from FB marketplace for $125 basically brand new

Getting back into 3d printing after a bit of a break, I have a Cr10s pro V1 but fried the motherboard(that’s a whole other project) I’d like to use the parts for something or get it back running

Thanks Happy Printing!!!!
