- Firstly, check if your thermistor connected to ChromaHead correctly. If not, please check the link below and make sure that all of your connections are true
- If your connections are true, check the serial paths of "chroma_head.cfg" and kcm.cfg"" or "driver.cfg". If the "chroma_head.cfg" and kcm.cfg"" or "driver.cfg" paths are written in reverse, the extruder temperature will be measured incorrectly.
