GF Not Cutting Through Proofgrade Material

Quite possible. Any swelling of the material (humidity) will cause incomplete cut through. You can slow the speed down by about 5-10 points and usually that will compensate for any slight swelling, and cut through in one pass. Or, you can pin the material down, check the cut, (I use a pick, but you can lift it out with sticky tape), and if it is not cut completely, send a second cut. Just don’t move the backing material and the second cut will land in the right place.
