Wavy lines when vector	∙	Running too fast	∙ The highest quality vectors are obtained

	∙	Dirty laser system	∙ Clean all optics, rails, bearings and belts
	∙ Worn or faulty bearings		∙ Check and/or replace X and/or Y axis

Angled cuts when cutting	∙	Angled cuts are a normal condition if	∙ Cut a square and observe that each side
through thick materials such as		they are equal on all sides of the object.	is slightly tapered inward.
