What is the problem?

My printer hangs sporadicly, only when it is connected to octopi. using the onboard µSD, it can works hours ans hours.
When the printer stops in the middle of printing there is no home position or retraction, the head remains on place, heating for a while and making a crater in the plastic. The raspberry is in a shutdown state. if I press the button it starts immediately. (pin 5 & 6)

the problem occurs twice this morning.

What did you already try to solve it?

check updates, restart all the chain, switch all devices on Lan rather than wifi.

Have you tried running in safe mode?

I don't know how to run safe mode.

Did running in safe mode solve the problem?

the printer's power cable is connected to a intelligent power plug handled by home assistant.
the only script pointing to this device is handled by octoprint with the plugin "PSU Control - HomeAssistant settings" and the printer is never switched off.

Ok for safe mode, I will try when my printer will be free, it is printing from µSD card.
by the way, I can work one or two days without any problem, but this morning, it happens twice.

Hello @bentou !

There are a lot of errors caused by the homeassistent plugin. And in addition (or as as a result by the first one) issues withe the crealitycloud.

Ok Ok,

the creality stuff is already removed, I don't use it.
I removed also the HomeAssistant Discovery plugin.

I would like to keep the printer's power plug managed by octoprint...
maybe I could find a wifi based power plug ? could it been managed by octoprint ?

let see if its continue or not...
