How to get more power!

Hey guys:).

I have this laser cutter:


(with the 7000W upgraded laser)

I am trying cut through 300gsm card (pretty thin) and can get through it at 100% power on 200mm speed on 2 or 3 passes. I just expected my laser to be way more powerful though.

Is there anything I can change? Any help would be great!

The best advice you’ll get is to add air assist for cutting:

Aside from that, make sure your focus is good. Diode laser are fairly weak, so proper focus is also very important.

Thank you.

Fish pump air blower
Metal straw
