Like SCAL, SignCut runs alongside CorelDRAW. It has a "Hot Folder" feature. Export your CDR as an EPS or PDF to a folder, and SignCut automatically loads it for cutting.

Place the printed sheet on your plotter. Press the "Scan & Cut" button inside the KX plugin. The new version uses (if you have a USB microscope) to align the blade to the first mark automatically.

Have a specific legacy plotter model? Drop the model number in the comments (or your local sign forum) for precise driver links.
