Geeetech

Geeetech a30 records temperatures of - 19 or lower temperatures than the real ones, causing the hotend to heat up more than is due to change the thermistor but the fault continues thermistors are tested on an arduino plate plus ramps and there they work Well, it is possible to use another pin to connect the temperature sensor and update the firmware?

Hi, You mean when your thermal termination is on the motherboard but the temperature still shows -19?
Is the temperature displayed by unplugging the hot end cable from the motherboard?
If you unplug the cable from the motherboard but the temperature does not show -14, it may be a problem with the motherboard

In fact, several tests have already been carried out and the cable has continuity until the pin of the card, in addition to times it shows - 19 or in others it shows lower temperatures than the real ones. Geeetech support staff checked the fault and indicate pin failures and will send replacement for warranty but in the meantime I want to give you a solution by changing the pin and configuration

Hi, did you manage to move the extruder temp sensor pin? I’m having the same issue. Thanks
