I have some trouble with really bad x axis vibrations. So much in fact. That the print itself is basically rubbish after the print.

If i move the x axis with the LCD Menu, all is fine and basiblx no vibration is showing. just when i print a gcode it vibrates badly.

My ideas to track down so far:

- Stepper driver motor current to low
- Acceleration in the gcode/firmware to high (I used the values from the original Snappy FW)
- Jerk settings to high
- Missing lube (but its moving fine when useing lcd movements...)

For now i wall back off from the lube as everything gets really messy with that...

Any ideas and tips welcome in the comments.
Thanks
