I’m using the AtomStack Pro 7 mine has no problems cutting thru 10mm wood so far on poplar. Far as the jarvis quality it’s amazing for bas relief carving. Poplar settings 48 power 3000mm. Also recently discovered if you exceed 500 lines it skews the image so fair warning stay at or under 500 lines. Also the compression on this laser almost doubled the depth of a 30w use caution on the power.
