@tylersuard if you send M308 S0 from the DWC console, what is the response?

@phaedrux I'm using Simplify. I add new one gcode in Python DSF which set temperature for all beds and replace M140.

But I still don't understand why it's impossible to configure multiheater bed. For extruders it works nice.

@vandermeulen said in heated bed temperature fault:

@engikeneer Okay, I hadn't found the M143 command. Let me try.

While you play with M143, you can loo at the heater's monitors in the DWC object model section. It will show you the internal affect of your M143 on the RRF internal configuration.

Here is a fudge which might work. Completely off the cuff and untested. But if you create a dummy tool (say T3) and assign both bed heaters to it, then you could use G10 to set the standby temperatures for both heaters. You'd likely need to set the active temperatures too. Then if you initial make that tool active, it should start to heat, but when you make the normal hot end tool active, the dummy tool (the bed heaters) should maintain the standby temperatures. To use G10 with multiple heaters, you use the colon separator for the S and R values which means that each heater is given its own set value. So you could run one at say 60 and the other at say 70. Although in practice, thermal conduction might preclude that from happening.

@dc42 this is the problem, thank you. I will try to repair it

Awesome, thanks. I just didn't want to have to install that separate MOSFET board if I didn't need to.

Thanks for pointing out the config wizard. I hadn't quite gotten far enough to look into that.

Thanks.

@JamesM Thank you, that's what it was. I had a 10amp AC plug sitting here. Switched it out and it worked. Got my pid tuning finally done.

@charding You might also consider putting insulation under the bed if you are able to do so (or increasing the amount of insulation if you already have some. It will, a) speed up the warm up time and, b) slow down the cool down time.
