Purchased a Atomstack X40 Pro (24W/48W Power) a month or so ago. Been pretty impressed with the cutting speeds. I can cut 1/8in Basswood in 1 pass at 600 Speed 80% (48W) power. I can cut 1/4in Basswood in 1 Pass at 400 Speed 80% (48W) power. Engraving tumblers at 2000 Speed at 40% Power (24W). Glasses about the same. If anyone is looking for a machine i highly recommend this one
