Marlin Firmware updating

#1
I have no idea what I'm doing when it comes to updating the firmware on the gMax. Can anyone give me a step by step of what I need to do? I still have the stock firmware, whatever that may be. I'm also on Win 8.1 x64.

You are awesome ray, thank you very much. Also, I have upgraded to the E3D v6 hotends, where would I go about setting the max temp settings so I can print at higher than 225c? What are the main improvements with the newer firmwares? Anything that I would notice?

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.
