UM2+ displays "1 second remaining" after nozzle change

[cdwilks 0]

Hello fellow UM enthusiasts,

I have a problem with my UM2+ and UM2+ Extended machines, after changing the nozzle.

I follow the recommended UM guides to replace the nozzles, and setup the machine. Everything looks fine.

Now, on these machines, all print jobs show "1 second remaining" on the LCD screen, regardless of the job duration or remaining time. I suppose its a bug of something, due to the changing of the nozzle.

Has anyone else experienced this?

Will a factory reset resolve the glitch?

Is there a reason why this is happening?

It has happened just on the machines that have had their nozzles changed, so the issue is directly linked.

Thanks in advance!

Chris
