Head Heating very Sloooowly
Afternoon,
I have a Prusa 3d kit that I've setup. I run a test print and the hot end never makes it to temperature It gets to about 50 degrees the fan turns on and it never gets past that. The fan will kick it below 50 which turns the fan off. So the fan basically goes off and on.
My bed hits temperature in about a minute and its fine but after 10 minutes my Extruder still isn't to temp.
Any ideas?

First, please check all the connections, if the connectors are all the way in and the screw terminals tight.
Re: Head Heating very Sloooowly
Screw Terminals are tight and connected per the wiring diagram. I checked and double checked when I was tshooting initially.
I'm probably going to pick up a infrared thermometer tonight. I want to make sure its not the sensor.

Can you measure the resistance of the heater cartridge? I just found out, E3D shipped us couple cartridges for 24V hotends labelled as 12V, hence it cant reach the temp.
Re: Head Heating very Sloooowly
You know,
That would make sense. I will check the resistance when I get home.

Getting 5.7 ohmz from the blue wires. The head looks like a E3d V6 if so that looks to correspond with their website.
Re: Head Heating very Sloooowly
after looking at both the hot ends it looked like a e3d V6 that I had ordered to install on printer I had returned. I swapped the assembly and everything works flawlessly.
I think it was a bad heat cartridge but after the swap I was printing in seconds.

If you used full V6, download the firmware and increase the MAXTEMP in the FW so you can reach the full 300°C.
