I had a 2500mw laser that typically cut with a 0.12mm to 0.15mm kerf. That met my needs.
Due to my abuse it died and I replaced it with the 3500mw model. However the best I can do is a 0.30mm kerf.
Is this the usual performance of the 3500mw model or a defect?
Does the 2500mw model inherently have a narrower kerf?
