Shakes/vibrates on endstops when starting print on G2S Pro

[thd610]

hi all,
Sometimes when I start a print on my G2s Pro it starts to hammer the end stops during the homing procedure, this only happens when running a print not otherwise. This seems to be a random thing and happens about 50% of the times, if this doesn't happen it just continue and prints just fine.

Running latest Repetier-host and Slic3r on Win10.

Any suggestions?

Thanks
