problem attuning bed heater
-
M303 autotuning procedure for bed heater never ends.
failing to calibrate it automatically every time I start heating the bed I get this error.Error: Heater 0 fault: temperature rising much more slowly than the expected 1.6°C/sec

make sure you have m501 in config, and m500 after autotune
-
@konte1978 Make sure you have the correct B value in M308.

@Stephen6309 i don't know the B value in M308, how can i get it?
-
it should be in your thermistor documentation
-
@Veti said in problem attuning bed heater:
t should be in your thermistor documentation
unfortunately I have no documentation, I made the mistake of getting it on amazon

@konte1978 Write to the seller and ask for the beta value.
-
most likely they used the very common B3950 thermistor
-
I entered the b-value of B3950 and launched the calibration. Nothing changes, I do not know if it is the fault of the 8mm plate that I used for the printing pact. increase of the test. -

What firmware version are you using?
Your screen shot shows the tuning process is running.
Does it ever finish? How long are you waiting?
Does it ever throw an error message?
When it's complete you need to send M500 to save the results. -
@Phaedrux Hi I'm using RepRapFirmware for Duet 2 WiFi / Ethernet version 3.2-RC2.
the test goes on even for 30 minutes without giving any error -
The new heater tuning algorithm in 3.2 can take a long time. Just let it finish.
