Extruder wobbles while moving in X direction

Symptom

While moving the extruder from X-min to X-max, the Y linear blocks wobble in about 0.5mm ~ 2mm periodically.

Solution

• Too high and uneven XY belt tensions. Make XY axes square and tense the belts evenly, at least similar to each other.

• Too low driving current. The default is 800mA.
