I will start by saying I have been using the titan 2 for around 2 yrs and I have changed the blade several times. One minute the machine is cutting perfectly and the next minute it is either cutting too deep or too swallow. I cannot cut any small lettering- it removes the vinyl before its done cutting. I have been trouble shooting for over 2 hours. I tried changing the blade holder and even another new blade. I don't understand how changing colors of vinyl is impacting this...same vinyl just a different color. Any ideas?
