Printer rails are not perpendicular

[huguescmoi 1]

 

Hi,

I have a my UM2 since end January this year. As I progressed in the size of the prints since then, I then realized my prints that were supposed to be perpendicular are not : they are skewed.

On a print of 5cm x 5 cm (still relatively small), two opposite sides are not parallel and the difference is a few millimeters !

I join a picture showing my printer from the top : it shows indeed that the axles are not perpendicular (see A and B distances are not the same on the picture).

How can I fix that ?

Thx

I think you need to give permission so that we can view your picture - I cannot!

I have made the picture public now, sorry. (what a pain in the @@## this bulletin board to join a picture!)
