Slow warmup on the heated bed
-
I have this issue.
Can someone explane what goes on here?

@heide What type of heated bed do you have?
Usually the team that scores the most points wins the game.

@heide Ok, that error simply means the bed is not heating (or Duet does not detect it as such). Does the bed feel warm? There are a number of things you can check, firstly if the bed is warm the thermistor may be disconnected or broken. Secondly is your relay working, and do you detect a completed circuit or full 220 volts when on?
You may also want to check to see that your bed thermistor is configured properly. Are you using the keenvo thermistor that's embedded in the silicone pad? Can you post your config?

@heide tune your bed using M303 H0 S60
Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

And make sure to send M500 to save the results to config-override.g and add M501 to the end of config.g to load them at startup.

It varies depending on how thick the plate is. The thicker it is the longer it takes to cool down between cycles. On my 300x300x6mm plate and 600w 120v heater it takes about 15 minutes to tune to 75c.
