BTW: You should better use PrusaSlicer - it is the faster and actively developed version of slic3r. But works the same and can also read the slic3r configs.

I get this preview in host:
no Cura e no Repetier-host não tenho problemas no eixo Z.
It is not possible to control only one z axis - if that happens you have a problem like moving z too fast and one axis is loosing steps. Make sure PrusaSlicer does not overwrite accelerations and motor currents (it has a checkbox for that in printer settings I think). And make sure z max speed is set correctly so no lost steps happen on your printer.
