Hello, i have a vibration problem with my printer which i cant solve. The extruder and bed all move nice and smooth when moving by hand but when printing the motors vibrate like crazy and i can feel by hand that they dont move smooth, the bed moves with huge vibration and it causes bad prints and its also super noisy, i can hear it 2 rooms away. I have changed the bearings, tuned motor voltage(the small thing you can turn on top of the stepper driver), tightened all screws up so i can be sure they dont cause that huge vibration/sound. I really dont know what to do and i have been trying to solve it for months now, i cant find any solutions to this problem on google, i have basicly tried everything. I am in such a struggle i can even pay for whoever can help me solve this problem. Video: https://www.youtube.com/watch?v=aSkXePPX2CE Note about video: The x axis is just noisy, it doesnt vibrate. The huge problem is Y axis, which vibrates. I got an suggestion from another forum that these steppers drivers could be broken, is that possible? http://ift.tt/2dVEbPm
