Five settings that fix most bad cuts

A bad cut is almost never the design. It is nearly always one of five settings, and they fail in a predictable order — so check them in that order rather than changing three things at once and losing track of which one helped.

1. Blade depth before blade pressure

Pressure is the setting everyone reaches for first, and it is usually the wrong one. If the blade is not extending far enough, more pressure just presses the housing harder into material it still cannot reach — which scores the mat and dulls the blade without improving the cut.

Set depth to the material thickness first, then adjust pressure.

2. A new blade is not a sharp blade

Blades pick up a fine coating of adhesive and vinyl dust long before they go blunt. A blade that "suddenly stopped cutting" is usually just dirty. Push it into a ball of aluminium foil a dozen times before you replace it.

3. Multiple passes beat more pressure

For thick cardstock and chipboard, two passes at moderate pressure produce a cleaner edge than one pass at maximum. High pressure deflects the material away from the blade, so the cut wanders.

4. Mat tack is a consumable

If small pieces shift mid-cut, the mat has lost its grip. Wash it with warm water and a little dish soap, let it air dry, and it will come back several times before it needs replacing.

5. Node count, which is a design problem after all

The exception to "it is never the design". A file auto-traced from a JPEG carries thousands of redundant control points, and the blade stutters at every one. If the edge looks faintly polygonal when you zoom in, the file is the problem — see what makes a good cut file.

Change one setting at a time and cut a 1-inch test square between each change. It feels slow and it is far faster than guessing.
