I have a 100w chinese machine that cuts without issue but I ran a raster engrave the other day to remind myself how inept it is at engraving. So I'm looking at cutting on the 36x24 bed and engraving on the ??? Speed appears to be more important than size as I would place the cut part in the engraver. For example, would a 30 w Trotec or similar be a good choice and what size bed would be ideal, given that a cut part would hardly be larger than 18x18 ever, your thoughts?
