Hi everyone,
Has anyone successfully replaced the Creality K2 Combo hotend with a K2 Plus hotend?
I am asking because the K2 / K2 Pro hotend is rated at around 70W, while the K2 Plus hotend uses a 100W ceramic heater, designed for higher temperature and flow performance. Because of this difference, I am unsure whether the K2 Plus hotend is a direct replacement or if there are hardware or firmware limitations.
Additionally, I am unable to find K2 or K2 Pro hotends on AliExpress marketplaces. All available listings appear to be K2 Plus hotends, which makes me wonder whether users are already installing them on K2 or K2 Pro machines.
If anyone has tried this, I would really appreciate feedback on the following:
Whether the swap works reliably or not
Heater and thermistor connector compatibility
Possible risks to the mainboard, heater MOSFET, or power circuitry due to the higher wattage
Any required firmware changes such as PID tuning, temperature limits, or thermistor configuration
Mechanical compatibility, including mounting, nozzle system, and clearances
Any real-world experience, whether successful or not, would be very helpful. I would like to avoid damaging the printer by installing an incompatible hotend.
Thank you very much in advance for your guidance.
