Hi All,

I am giving up on active levelling.

 

For the first 1k hours or so of my UM3. It worked great. Never any issues and i was super chuffed with it. 

 

But around 2 months ago I had issues -  got feedback from here and finally got it working again.

 

Today after much stress i have turned it off.

 

The bed will just not active level. I have tried everything from printing off guide bars, to manual levelling twice in a row. It just constantly trys to mash the heads into the glass and shunts down. It randomly gives me an error22 or when it doesnt do that will tell me the distance between heads is too extreme. 

 

I have tried everything, the official guide is terrible. I have just manually levelled and now am turning it off. Which is a massive shame as it was a great feature to have. 

 

Rant over

    Can I get a picture of your bed at eye level from the front?

     

    If the heated plate is too high, the Print Core will get pushed inside the print head which sounds like what you're seeing. The bed height should look about like this. If you've got a gap between the heated plate and the lip at the front, it's going to do what you're describing.

    I will take a pic later, i have tighted all screws until tight and then unwound three turns as everyone describes. Still the same issue...

    The print cores are definately mashed into the print head.
