    I would like to replace my laser head set and upgrade the mirrors. Can you please suggest a good lens and mirror size? The standard the come with the machine are 12mm for the lens and 20mm for the mirrors. Is the 20mm lens better in performance than the 12mm stock? I normally cut 3mm and 6mm ply with my machine.
    Thank you for your help
