RE: MIN/MAX AMBIENT safety checks

According to the release notes for 3.9.1:

The “AMBIENT_MAXTEMP” is set to 100 °C, if this temperature is reached, the printer will immediately cut power to the heaters and motors to reduce power draw. Resuming the print is not possible. The only allowed operation is resetting the printer, the user is also highly advised to inspect the board for problems before attempting to continue printing.

Before disabling the check, might be worth a quick inspection of the board.

Yes, I have checked the board and everything seems to be OK.

So how can I disable this check?

RE: MIN/MAX AMBIENT safety checks

I'm not aware of a way to disable safety checks. I definitely wouldn't disable MAXTEMP warnings. Log in to the online store and contact support via chat. There may be a quick fix that doesn't involve disabling safety features.
