Hi Jeff and John,
I remember in your instructable on the Shapeoko2 laser engraving...you changed the Shapeoko''s stock GT2 belt pulley to another with smaller pitch. You also changed the stock Belts too to one of smaller pitch.
My observation with X-Carve is the stock Pulley is irremovable. In that scenario how does the laser engraving with the X-Carve achieve those fine laser step overs when the stock GT2 pulley and belts are used?
