Re: [CAD_CAM_EDM_DRO] Re: tangential cutter software

Add to Dougs suggestion the fact that many of the Vinyl cutting programs can
actually cause the "post" to "overshoot" the corners by a user set amount
(offset of knife). For Example, this technique creates a "loopy" looking
toolpath path in order to make a square corner.
