My i3 has a Melzi v.2 board,and although the green led was flashing,the hot end heater was not working.
I tested the thermistor and heating element,they are fine.So what,if anything,goes wrong with this board?
I have a ramps set up on the slow boat,but I'd still like to know why the melzi went wrong.
it annoys me if something simple slipped by me.
