I've definitely cut through a ton of 1/4" ply on epilogs - in my experience,
wood is significantly harder to cut than plastics. If you go slow,
everything catches on fire. too fast and nothing happens. I've had luck
using the highest power I can manage, and then adjusting speed/passes
accordingly to make sure wood doesn't burn. Unfortunately, since a lot of my
work has been on 60 or 100W systems, the setting I generally use are
probably not very applicable here...not sure if that really helped or not...
