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 cutter applications as they require less torque to keep the cutting bits moving.

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x m = 1 Nm. Typically, a safety factor is used so that the ...
