Hi Thomas,
Hope you don't mine I put your post thorough google translate [

Hello,
I just bought an Arduino Mega kit with a shield plate reprap RAMPS V1.4 and I encounter a problem with the motor axes.
- First of the stepper motor is not my Z axis does not, by that I mean that when I give an order the rotor does not rotate but vibrate and my ammeter panics, I immediately thought about an engine problem but all the others react in the same way on the Z axis, as a result I thought of a microcontroller problem here but like I'm reversing or even change the result remains the same . In conclusion all axes It Works well except that one.
I then asked for help from an electronics confirmed friends, and he told me that the problem might come from the fact that the motor on the Z axis receives excessive pulse frequency which would consequently of the unsynchronized, and thus explain from where the vibrations of the rotor.
- In the following is the problem of calibrating the distances traveled by motor, what I mean is that when I told him to rotate to achieve a race distance of one millimeter at the carriage, celui- it is not a millimeter, but much less. Here I must say that I do not understand where can come the problem.
The engine I have in my possession are 1.8 ° angle motors (1/8) so 200 not 360 degrees, but I do not know it it is small or big steps, is t he conversions or pulse rules.
For code I have not followed trunk tutorial and I ended up finding a quote for configuring preliminary settings and then quote handles the conversion Arduino program, here is the link of the quote:

The problem is that even following the configuration of tutorials on this site I have problems and not them.
I am a beginner in this field and open to comments
Thank you in advance for your raiponces.
