UM3E Bed leveling Fails

Recommended Posts

Posted · UM3E Bed leveling Fails

When I auto level the bed on my UM3E the head is always closer on the back, so close that it actually touches the bed and the extrusion is nearly nonexistent. The front is perfect but the print is a perfect gradient front to back. I've noticed that the rear spring is very much less stiff than the front two. Could that be the cause? Any other ideas?

Could you try to rotate the glass plate by 180 degree around z axis (maybe you have to remove the sticker) or use a different glass plate in order to exclude the glass as the source?

If that's the case, the build plate seems to be a bit skewed.

Doing a manual leveling first might help fix this.

After the manual leveling, the automated bed leveling would have fewer problems.

I did an auto level then as the printer printed I adjusted the back screw to lower the plate to get a fairly even layer. I then stopped the print removed the print and did another auto level. Again the front of the printer is fine with a gradient to the back of the printer where the layer is nonexistent. Auto leveling is simply broken on my machine. Not sure where to go with this.
