hmmm didn't realize I posted in the black cat.
So I put the cable back in the square slot last night. When I originally started the project I had issues with the roll sliding so had cut the vinyl in the size I needed it and put it on the mat. Yes I probably need a new mat.
Last night I recheck the blade (already a new one), use the setting pad for depth, made sure it was tight and went back to the roll.
No dragging.
So all is well for now.
Thanks for all the support & suggestions.
