7000mW diode laser trying to cut through 3mm plywood

Need help with trying to cut through 3mm birch plywood on my 3018Pro 7000mW diode laser. I can only get it to cut part of the way through it doing 5 passes but there should be some type of setting I need to set to get it to go through it. Any help on this would be great.

Plywood will be a problem. See this article:
