Hello. My Titan 2 cutter will cut half the project fine, but then stop cutting all the way through, and start scoring the material. I have to take an exacto blade and cut along the scored line to get it to release. I have a brand new blade, set properly. As stated, it starts the cut perfectly fine. I've used this cutter about 2 years. Any advise as to what could be making it do this? I've adjusted the pressure and it doesn't matter. Same result. I can't overstate this... The cutter will BEGIN the design just fine. It weeds out perfectly, then it stops cutting deep enough. Also worth noting, the blade holder is clean and secured tightly into place.
