@Pier-Andrea-Tornatore You may have damaged the gears on the servo and perhaps the stepper drivers. I would suggest ruling out the software, if it does the same thing using T2Laser trial (click the EleksDraw option in the Configure EleksMana menu before you test anything as this will ensure the servo can't over rotate and be damaged).
@franzie8912 If you have the Eleks Mana firmware loaded and configured for servo operation then I suspect you ran it with EleksCAM or other software and over rotated the servo which will strip the plastic gears. That's why T2Laser automatically sets the laser max to prevent this.
@ali-yusifov It is probably the configuration, you can test with T2Laser (I have a menu specifically to set the EleksDraw, you just click the option and everything is set correctly). Using the machine without the correct parameters can strip the servo gears so be careful, set laser max to 35 to be safe.
@Request Just reverse the axis, in T2Laser you can click Reverse Y Axis in the settings menu but I'm sure there's similar options in other programs. If not you can manually edit the Grbl parameters to fix it.
