Well i have a problem with my newly installed e3d hotend on my velleman k8200. The thermistor works, if i keep my finger to the hotend the temperature will go up. But the heater cartridge for some reason does not work. Any idea how to fix that? Or is there something i need to update in the firmware?
Have you got access to a multimeter, if so test the resistance over the heater plus you could test you're getting voltage to the heater also.
