I am fairly new to CNC. I do have a small CNC engraver and was looking for a larger one. I was just about to order a Shapeoko 4 when I discovered that the resolution was 40s/mm! The Longmill is 200s/mm (with 1/8 micro) . It is also about $600 less expensive. My small cnc is primarily used for PCB prototyping. The 40s/mm doesn’t cut it. The 200s/mm should be just fine. Is it a no brainer, or am I missing something?
