Drag-Knife

This plugin takes selected polylines and generates new polylines that will be used to creates drag-knife tool path.

From the tool path polyline, an engrave MOP must be used to create the actual tool path and G-code.

Documentation	Knife Tip Offset: knife tip distance from tool centerline (typically this is 1/2 the tool diameter) Cut Depth: set to material thickness or slightly larger to assure cutting through the material A positive value for CutDepth will be set as a -Z value. This value would be equivalent to the Engrave Depth. Swivel Angle: this angle is used as a precision factor If the angle between segments is SMALLER than SwivelAngle, a Swivel move will NOT be produced. This will make the cut smoother, but less precise to the original path. Default value is 5 degrees. Dent Length: ignore "Dents" created by converting bitmaps to paths Retract Enable: this is a toggle to enable the Retract Feature Retract Angle: this angle is used for the Retract feature If the angle between segments is LARGER than RetractAngle, a Retract move will be produced. For thicker material like cardboard, this prevents gouging of material during the swivel move. Default value is 40 degrees Retract Depth: a smaller retract depth used during the swivel move A positive value for RetractDepth will be set as a -Z value. As a suggestion, try 1/2 the value of the CutDepth. Polyline direction: allow to change the polyline direction (CW, CCW) Prior to start the machining, the knife edge must be oriented (manually by the user) toward the +X direction to assure that the knife tip plunges to the exact position of the first cut path.
