I won’t bore with a text wall but i did want to say how amazing E3D customer support is. I upgraded to an e3d hotend and it worked extremely well for a short time. It started having problems with underextrusion and clogging as the print progressed. I contacted E3D customer support they were patient and walked me through the troubleshooting steps. When it turned out that the issue was the thermistor, they shipped a replacement part no questions asked with super fast shipping. The package ended up at my door less than 48 hours from when they had my address! Thermistor is installed and first print is underway but I wanted to give a shout out to e3d for such amazing customer support. http://ift.tt/2ncf277
