Blurry and split ends on engraving

The engravings are showing split ends kind of design on the very thin edges of the picture. How do I fix this!

You should check the tensions on your belts. It might also be worth trying the engraving with bi-directional turned off or at a slower speed with a higher power.

It was engraving fine but suddenly started to give results like this. Also should I loosen the belt or tighten it ? And 1500 is an extremely low spees, should I lower this more ?

Tighten the belts and if using air assist make sure the material in secured as i’ve had the air get under the material and move it.

Okay, I’ll try with tightening the belts and no I’m not using the air assist.
