[UM2 Z-axis not leveled.]

I'd check that first.  Does the printer sit flat on a table?  Or does it rock?  If the frame has banana then you need to loosen a lot of the frame screws and push it back into position and retighten.  On extremely rare occasions back in the UMO days there were some "bad" frames where the wood shifted during cutting.  Now all frames go through quality control.  It's possible to order just one side of the frame. 

 

The base plate that you show as bent shouldn't matter as it connects to the heated bed through 3 points.  You can't transfer "banana" through 3 points.  You can just adjust the 3 screws to make the bed "level" with the gantry.

Yes! it does rock! when I loosen the screws I should just tap it with a mallet to knock it into shape or do I need to remove the screws to do that?

The frame has tabs that click into each other so it looks like hitting them with a hammer might break them.

 

Thank you

Hello All

 

I have been trying to fix a bed leveling issue with my UM2. All 3 points of the bed are all at very different heights and when I try to adjust the screws to get those 3 points leveled it throws the 2 back corners (where there are no screws) off being leveled.

3 possible sources of this error:

1) glass is bent 

2) heated bed is bent

3) aluminum carriage (Z-axis) is not leveled.

 

Since #3 is what everything attaches to I wanted to test that first. Long behold it was totally not straight. When I brought the build plate all the way up (with the heated bed and glass removed) all 3 points had different heights from the nozzle to the bed. Look at the 3 pictures.

 

Is this normal or a fix for this?

 

Thank you all for the help in advanced.
