Temperature sensor error message

geon han_Kang · 21 Apr 2022, 01:32

Hello.

I'm making two printers, but I'm inquiring because there's a problem.
A heater temperature reading error message appears and continues to interrupt while one printer is leveling the G29 bed.
However, temperature sensor sensing works well without errors.
I wonder what caused this.

Have you PID tuned the heater?
Can you control the heater by setting a temp? Does it rise and maintain as expected?
Can you post your config.g and the results of M122 and M98 P"config.g"?
What kind of heater and thermistor is it?

@phaedrux Thank you for your answer
You can control the heater by setting the temperature. It rises as expected.
I don't know exactly what kind of heater and thermistor are, but I think it's 1000K 24V.

@geon-han_kang The error message refers to heater 2 sensor being open circuit. You haven't yet posted your config.g file so it's hard to say what the problem is but looking at the screen shot, my best guess is that you have associated heater 2 with tool 0 but without first configuring heater 2. Please post your complete config g file and your config-override.g if you use it.

@geon-han_kang said in Temperature sensor error message:

M550 P"CONCEPTION" ; set printer name

It's complaining that this does not match the Pi hostname.

As for the open circuit error I think you may have an intermittent wiring break.
