MH721 - Not cutting through vinyl intermittently - please help!

Recommended Posts

Right, my mh721 has recently started with yet another problem!

A week or so ago i noticed that some cuts werent a consistent depth and in some areas the vinyl wasnt cut enough to weed properly.

So i put it down to old blades and bought new ones, didnt solve the problem.

I have upped the pressure but doesnt help, you can clearly see the blade being lifted very slightly in certain areas by the machine then dropping back down and cutting as it should.

Checked cutting strip and it was slightly bumpy, cleaned that up so its nice and smooth and still no change.

Carriage is on tracks, cleaned the tracks with cotton buds and it's still happening!

Cutter is on a stand, grounded and i'm using signblazer via serial cable.

I have a pile of orders here and customers getting really pissed off

fixed! it was every time the blade passed the unused middle pinch roller it was causing the blade to lift for about 20mm (static?)

narrowed it down to the same spot, moved the unused roller to one side and a boom! no problem!

i dont use the middle roller as it always screws the vinyl up and puts grooves into it, is there any way of removing it or setting it up so it doesnt do that?
