Before I dig too far in to the details on this, can someone state what the "max" cutting ability for this type of system would be? How thick a piece of ABS, wood, paper, etc. could this cut through (not engrave/burn, but cut)?

I have an old Chines laser engraver that was damaged in transit to me that I have never run. I think it is a 20 W CO2 from what I recall, but again, before I invest time in trying to resurrect it I want to know what reasonable expectations for performance are... Thanks in advance!
