Hey there! I have a 1515 workbee and i have The Problem that The y and a axis are vibrating/grinding while im doing a Job as you can see in The video. Motors are Pretty loud but i have no missing steps. X and z are Perfect! Colling for The x pro v3 is on, belts and pully Are tight, if checked The settings which after playing around didnt seem to make any diference. When the Electric is of i can feel and here some vibration when moving the y and a axis. I made a video to so you can hear that, if that is maybee The Problem?! But if i want to go to home or to Zero The Maschine drives smooth as it should. No vibrating So i Hope you guys can help me there !
