You're welcome.
Not sure about the newest. I'm running the "intermediate firmware" - almost the original but after the main fixes, I believe from April of this past year.
I've learned how to configure Marlin from scratch, have done that for my Cohesive 3D Printer, and in the future when I figure out auto-bed leveling I'll manually do the Configuration file for the gMax. Actually, I just haven't gotten around to mounting a servo to the extruder carriage, the firmware config is easy.
