Recv: Error:Heating failed, system stopped! Heater_ID: bed

What is the problem?

When starting print from OctoPrint, one out of every 10 or so prints fails with:
Recv: Error:Heating failed, system stopped! Heater_ID: bed

What did you already try to solve it?

Manually heating up bed before hitting print resolves it.
Sometimes it just doesn't happen

Have you tried running in safe mode?


Did running in safe mode solve the problem?


Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!) (32.8 KB)

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

OctoPrint version: 1.10.1
OctoPi version:Build 2023.10.09.151442 with "webcamd"
Printer : Sovol Sv06 Plus:
Firmware: V1.1.4 Marlin
Browser: Edge
OS Windows 10 64bit

I have an identical machine with identical Raspberry Pi and same settings that does not have the same issue.

Any help is greatly appreciated.
Thank you


Attach the systeminfo bundle to your next post.

Without it we are just guessing.

Sorry I did attach it from my google drive but forgot to update the text from Write here to something indicating this way to the files. didn't realise I could upload direct.


Why not? We always get the recent post to be shown.

The extruder can not reach the desired temperature.

  • Check the proper seating of eating element and thermistor.
  • Check the wiring.
  • Check the PSU

You can see from the terminal printout that it is the bed that is failing to heat. The target temperature is 60 degrees, but heating is stalled at around 35 or 36. Unless you have your printer installed in your sauna, it looks like the bed starts to warm up and then stalls out.
This would suggest that there is power to the bed heater, but the temperature readback is somehow faulty. As a guess, I would look at the underside of the bed and make sure that the thermistor is in firm contact withe the metal. If it's hanging loose, it will sense the initial rise from simple heat radiation, but eventually convection will carry heat away fast enough that the thermistor won't accurately read bed temperature and will stop increasing.

Hello @SteveElves !

Thank you for your input.

As I mentioned in my post, that was marked by the OP as solution.
