Genmitsu 3018 Pro CNC Engraver
Good for engraving wood or marking pieces precisely to machine somewhere else, not so great for metal as it doesn't have much power and it's not sturdy enough to deform the cutting surface. Can do more than engraving but it takes a long time.
Quick start Use either Inkscape with a plugin (check Google) or Autodesk Fusion 360 (follow a tutorial), generate GRBL and use Universal Gcode Sender or similar to connect over USB. Check your milling bit to be sure it works as programmed, move manually or with UGS the tip to the desired zero position and home it. Secure your piece to the table using the screw clamps and give it a first pass.
