3 week ago my rostock max hotend just meltdown so i ordered a new hotend took the e3d v6 but now nothing work , i changed the number in the firmware , like i found but nothing even with a original thermistor nothing work with the stock config , al the axe move via repetier host , but impossible to heat the bed , the diode dont even light on , the temps for the hot end is always -20 or -17 and nothing change , i tryed with 3 different thernmistor and nothing all was working nicely when the hot end break 3 week ago and did event turn it on after that , the tmpes for the bed show 22 this one is good but it dont even heat up
