It seems like you've encountered a heating issue with your Ultimaker 2 after changing the nozzle size. This problem can occur due to several reasons. Here are a few things you can check and troubleshoot: Nozzle compatibility: Ensure that the new 0.8 nozzle you installed is compatible with your Ultimaker 2. Check the specifications and make sure it is within the supported range. Temperature settings: Verify that you have adjusted the temperature settings in your slicing software or printer firmware to accommodate the larger nozzle size. Different nozzle sizes require different temperatures for optimal printing. Heating element and thermistor: Check the connections of the heating element and the thermistor (temperature sensor) on your printer. Make sure they are properly attached and functioning correctly. A loose or faulty connection can lead to temperature fluctuations and heating errors. Heater cartridge: The heater cartridge may need to be replaced if it is not providing sufficient heat. It's possible that the increased demand from the larger nozzle is exceeding the capabilities of the current heater cartridge. Firmware update: Ensure that your Ultimaker 2's firmware is up to date. Sometimes, firmware updates can address known heating issues and provide improved temperature control. If you have tried these troubleshooting steps and the problem persists, it would be helpful to consult the Ultimaker community forums or reach out to Ultimaker support for further assistance. They may have specific recommendations based on your printer model and the modifications you've made. Remember to exercise caution when working with your printer and its components to avoid any potential damage or injury. Good luck with resolving the heating issue!
