For desktop CNC routers with a work area under ' x ', you can go with NEMA 17 stepper motors. NEMA17 steppers are available with a holding torque of around 70 ozin. NEMA 17 steppers are mostly preferred for engraving and foam cutter applications as they require less torque to keep the cutting bits moving.
