1. The maximum heating temperature of SUNLU FilaDryer E2 is up to 110 ℃, please carefully observe the current set parameters (such as filament type, heating temperature) is consistent with the actual need to dry the filament, to avoid too high a temperature leading to deformation of the filament (filament drying temperature, recommended product manuals or this product page of the filament spool data)
For example, if the machine is set to operate at ≥70°C, the temperature resistance of the spool of the filament you are using should be ≥70°C to avoid deformation of the spool.
2. If the product set working temperature ≥ 80 ℃, humidity detection module will be in a protective state (display humidity <10%) is a normal phenomenon, when the drying box temperature is reduced to 70 ℃, about 20H, humidity detection module automatically restore the original precision
