I have been dealing with this issue for a month now and still not able to resolve it. I have replaced the heater cartridge, thermistor which reads the ambient temperature correctly. I have been working with Joshua on this and we thought it was fixed but the error has returned. I have a dual extruder 1.5+ but currently running with a single extruder. We have switched the wires in the electronic box and still have the problem. We have taken the the hotend and connected it directly to the electronics board and it heats up - but this is a short test not one that involves any duration. I also have the gTouch on my printer and with that comes an Astroprint Keychain test print which I was able to print today. However when I tried to print the g spiral test print I get the E1 Heating Failed Printer Halted message. I was wondering if anyone else has encountered this problem and has any suggestiongs?
Thanks
