[UMO+ starts prints immediately]

Usually I find solutions for my printer problems online, but for this one I failed. Therefor a new topic.

 

My UMO+ always worked fine. 

Now, when I want to make a print it doesn't first heat up, level the heated bed or go home,

but it starts to print right away (in the air and on quite high speed)

 

I checked with different files. turned the machine on and off to try again, same problem occurs.

 

Anyone has an idea what to do?
