I have an ender 3 v3 ke printer.
I bought the Creality Ender-3 V3 SE/KE Ceramic Heating Block Kit High Flow Printing 300℃ High Temperature Resistance Quick-swap Nozzle Kit and installed it…

However I did a test print and noticed that my print quality with this new hotend has decreased compared to the old hotend on the same test print…

Please advise

Hi
I fitted one of these to my SE and had to do a full calibration and adjust the Z height slightly.
I must say it prints great now, and heats up A LOT quicker.

Hi thanks for the response.
What is a full calibration?
