Trouble with factory hotend

I have been having issues with my filament skipping since day one. I have come to the conclusion after many forums and research that there may be a defect with my nozzle not allowing enough filament to be extruded. One thing I will note is that the filament really likes to CURL out of the nozzle instead of stream straight out. Where do I find a new one of these?

Answer this question I have this problem too

Is this a good question?

Are you using stock settings? If so, could you tell me (in Cura specifically) is the filament diameter listed as 3mm or the correct 1.75mm? On some computers the factory settings did not upload and this error causes it to appear that filament is not flowing properly.


I made sure it was set to 1.75mm Is there any chance I could request a new hotend from the boxzy team?


No problem, I'll let them know you're having issues. Please contact and she'll get you setup. Just send her a link to this page, I'll let her know what's going on. Alternatively, you can send them the entire printer canister and they'll rebuild it for you.

Have you checked to make sure that the gap when leveling the printer is right?

If your head is too far from the bed, it won't adhere to the bed. It will tend to curl back up and make a stringy mess.

If the head is the right distance and you do have a bad head, then yes I have replaced the head, it is a metal JHead. This is the replacement type:

You will need your heater core as this comes with a 12V core, and the printer needs a 24V core.

Just some basic questions: PLA? temperature? have you tried tightening your filament feeder? Have you tried cleaning out the nozzle? I had to clean mine on the very first print.

if you're dead set on getting a new nozzle, this one looks pretty darn similar:

Aluminum, J nozzle, long black heat break. I don't see a bowden connector on it though, but I could be wrong.
