I am not seeing the screws to remove? Also could there be a setting on the plotter that I need to fix? or something in my signblazer settings? I have the setting in sign blazer on 0 as I saw somewere that was what it was supposed to be on. as far as removing what you told me too, are you talking about the casing next to were the blade is mounted? I really cant see anyway to get into, used a flashlight and don't see the screws. thankyou in advance, for your information!!!
