Re: Makergear M2 24V, V3b hotend- Thermistor Readings

what we were expecting is to get the resistance measurement of the thermistor, that is what gets plugged into the board and senses the temperature at the hotend. its resistance will change with temperature and is how the board can sense the temperature. Thank you! I was indeed measuring the wrong c...

Re: Makergear M2 24V, V3b hotend- Thermistor Readings

Resistance is 40kohms. Is that with the thermistor unplugged from the RAMBo? I'm measuring the resistance and voltage across the terminal pins at the board. I'm also measuring the resistance and voltage across the connector pins on the hot ends. And yes, it's fundamental not to measure resistance o...

Makergear M2 24V, V3b hotend- Thermistor Readings

Howdy! I'm getting a MINTEMP. Trying to troubleshoot this. I've measured the voltage of each thermistor terminal (T0, T1, T2, and T3) at 5V. Resistance is 40kohms. Measures the same at the hotends for both extruder and bed. 40kohms seems too low. Is this correct? If so, what needs to be replaced? Th...
