Hi Roxy, Thanks for the quick reply.
I apologize for being so vague in my question. I took a few months hiatus from 3d printing and apparently a lot has changed!
Im looking for the latest stable version of Marlin for the MakerFarm Prusa 12 inch.

Secondly, UBL bed leveling and z-babystepping ..what???...How much did I actually miss?
Where can I find some info on these features? Im still using a Servo and switch for my Z probe.

Thanks for your time and help on this!!!!
