Skipping steps and others

Hello

Before everything, i've tryed every solution possible that i could find, adjusting the screw (under and over), adjusting the software, redoing the wiring, changing the stepper motor but i still get skipping on my y axis, is it possible it is a problem with the ramps?

It's a Prusa i3 with ramps 1.4, is the second printer i build with the first printing perfectly but this one can't get it to work well.

Some pictures to see a part i just printed and some problems with it.

That looks more like an over extrusion problem, not skipped steps on the y.

Yes, there was a bit too much on that piece but on the top part you can se the skipped steps.


Another pieces i've printed after all of that i've done before and this time i also changed the polulu and still got skipped steps.

Is it possible it could be a problem from the ramps?

With your over extrusion problems, you are bound to have excess curl on the edges. Your nozzle is likely hitting this and causing skipping.
