I purchased a Einsy Rambo a while back and I've struggled to get it working. The most recent development was that I've been able to get the X & Y axis to move manually without any issues, but when I attempt to home the x axis the motor just resonates. I've made several adjustments to homing feedrates from 300 down to 200mm/m to 100mm/m and up as high as 350mm/m with out any perceived change in the resonance. Attached is my config file.
