Angled cuts when cutting | ∙ | Angled cuts are a normal condition if | ∙ Cut a square and observe that each side |

| The front side of the object will always |
|
|
| be slightly smaller than the backside of |
|
|
| the object due to the material “spreading |
|
|

| If the pattern is excessive: |
| |
| ∙ | Dirty laser system | ∙ Clean all optics, rails, bearings and belts |
| ∙ | Mechanical problem | ∙ Turn machine off and check for binding |
|
|
| in the x & y directions. Check for |
|
|
| excessive belt tension. |
