Best thing to happen to my Mega-S yet
I first stumbled upon this because I needed a way to get a console running with my Mega-S. I downloaded Pronterface but I could not connect to the Mega-S because of some sort of "baud rate" issue. In looking for a solution, someone mentioned that after using David's firmware, it might work. So I gave it a shot.
Bingo! Now I can send (and more importantly) receive from my printer.
Well, i decided I probably should just go through the rest of the features of the firmware. I did the mesh bed leveling and BAM, my printer has never printed better. Especially with sub par filaments.
All I had to do was go through the mesh leveler setup once and I got great results with the mesh test. I should note, that I did calibrate my Extruder Esteps before going through the mesh leveling. Not sure if that's important to do first.
For anyone with the Mega-S I highly recommend the firmware.
