Heating Disabled by safety timer
Hello guys,
I have a prusa MK3S+ connected to a raspberry pi 4 with octoprint and I keep getting this error "Heating Disabled by safety timer" on the printer screen and another error on the octoprint page : Too many consecutive timeots. Printer still connected and alive.
The printer can run without problems a week or a few days of continuous printing and then it would fail for no reason. I have another printer connected the same way and never had a problem.
Any idea what the problem can be ?
Occasionally
I have not figured it out yet. I think it is a bug. It happens from time to time. I have no idea why. I think it is in octoprint because I don’t get it outside of Octoprint.

I'm missing something... Is this happening in the middle of a print? Because otherwise it's a normal safety precaution of the printer is sitting idle at print temperature for a while.

That is when has happened to me. I walk away while it is printing and come back to the error.

Haven't seen this myself, so I'm just speculating.… Maybe some connection error and disconnect of Octoprint, so the printer is sitting at operating temperature without getting any commands sent, until the safety timeout kicks in?

Yes, it stops in the middle of the print. I think the printer is loosing connection with the octoprint. I did try different USB ports on the raspberry pi but still does it. I just replaced the 2A power supply with a 3A one and ordered new shorter usb cables. will keep you updated

RE: Heating Disabled by safety timer
The problem was with the power supply. I was using a 2A power supply from my samasung phone. After I changed the power supply with a 3A one made for raspberry, everything is working fine.
Thanks
