marlin problem

I have a problem with my acrylic Prusa pro b
I've printed several pieces . and when I measure the size of the pieces do not match the size they should have .
I proceeded to calibrate and change the values in the marlin, and continues to do the same. ( repeatedly)
change the values from the screen of the Prussian and no improvement .
the real problem comes with the motor steps that I will not come casket up.
that is to say. I motioned 80.11 for example, and the printer does not change , are always to 78.74 . do so with the marlin or directly from the printer screen .
What could be the problem? a greeting

It's a bit weird...Take the liberty to ask,did you upload the firmware sucessfully when changing in Marlin and store the memory in LCD when change it in the LCD controller?

testing and from the lcd if you let me change the steps . but not from marlin .
I can change the firmware and even change the directions of the engines. but when I do it from marlin (only steps engines ) does not change .
firmware uploads bien.he I always tried different firmware and also uploads . but the steps will never change

The step/mm of all the motors can't be changed???And how big is the diffrence in the object you printed actually with the one you expected before printing?

Over the engines only let me switch from the LCD . Marlin does not change me . the difference in the x-axis is 0.6mm
