MaslowCNC as Cut markers

Is there a chance to substitute the router into a pen and just used it to mark cut lines for jigsaw routers, or circular saw, so measurement can all be done in the computer accurately, might be a great tool in doing cabinets, saving a lot of time in measurements

people have created pen holders that fit in place of the router. Be aware that
the change in weight will affect accuracy. You either need to make it weigh the
same or recalibrate when switching.
