trouble with rectangular cutout

Post by oe5hpm » Mon Mar 12, 2018 6:34 pm

A cutout is made with direction "inside".
While direction outside is working as expected, the "inside" generates a weird toolpath. As workaround i convert the rectangle to a polyline and insert a node in the middle, which is then declared as starting point for the polyline. The "5-point rectangle" has then a toolpath as expected.

Any ideas on this ?

Yes, this is exactly the right way to deal with inner contours. QCAD/CAM can only start at nodes, so a node needs to be added at the desired start point. BTW: you can directly set the start point at the middle of the side without having to add a node first. Setting the start point at any location where there is no node yet will insert a node for you.
