PROBLEM MECANIC IN CNC MOSTLY

Please I have a problem in the mechanism of my machine CNC MOSTLY.

how I corrected?

What is the problem? You should have a look at the sticky.

here is the problem:

make sure the outside rails are square, measure corner to corner diagonally. then loosen the bearings in the center section and make sure that you tighten the center evenly. that should help.

thank you very much
