Wanhao duplicator i3 print bed support warped As you can see in the picture, my heated bed support is too low on the right side, even touching the Y-axis chassis end plate. 



This is only the case on the front of the printer. The back is perfectly straight. Do you know how this can happen and what can be done?
okay, after ferociously dismantling the whole bed I found out that the bed and the bed support are perfectly straight!
So there is something  warping the bed and support. De Y-axis bars are perfectly flat too. 

I found out that my table is not flat! This made the complete printer warped and even bent the print bed. put some cardboard under the frontleft foot and presto! As flat as it should be!
