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.
