Greetings,
My MMSv2 has old firmware lacking the safety features for over temp.
I am looking for an official build of the firmware if it exists rather than hoping to get the configuration correct while compiling for the MELZI BOARD.
I found this write up but it is for the I3 which "should" be OK but I do not want to make a mistake and screw up a perfectly running printer there are settings I am sure I do not know how or what to get before updating....... https://www.instructables.com/id/Using-an-Arduino-to-Flash-the-Melzi-Board-Wanhao-I/
Anyone been down this path before I would be grateful for your insight
