Please see the attached article for fitting/ adjusting A new/old HotEnd.
Some reasons you might need a new HotEnd are:
- Frequent clogging/ inconsistent extrusion in the nozzle
- Irreparable blockages
- Long-term Maintenance(printer has been in commission for a long time causing material wear)
- Heat break failure - isolates the hot end from the cooler parts which can cause extruder jams
After following the steps of replacement you MUST Calibrate Both Hot Ends:
- Level the bed
- Z-Offset
- Y-Offset
- X-Offset
