US Cutter SC Model Plotter Feeding Vinyl Crooked

Recommended Posts

Please help! I am brand new to this thread so please forgive me if I am putting it in the wrong spot. 

 

I have a USCutter Model SC Plotter which I run with SCAL Pro. I have done vinyl designs on it for a couple of months now, upgrading from my personal desktop machine. 

 

The problem I am having is that no matter how I set my vinyl to feed through the machine, it keeps feeding crooked as it cuts. It basically starts out straight, but it is feeding at a slant. 

 

I have tried taping a ruler to be sure I am putting the vinyl straight, using every single possible guide line, adjusting the rollers to different widths, but am stumped.

 

How can I make this machine feed straight? Can anyone please help me as I am losing so much time constantly correcting the angle of the vinyl.

 

Thanks so much!

first make sure you are prefeeding so it is not pulling the vinyl off the roll . . . . after that it is just trial feeding and adjusting the vinyl until it is going straight

Are you locking the hold down rollers all the way?

Can you post up a pic of where you have the rollers?

I know on mine the lines in front and back arent lined up. I have to line it up then feed it through, then adjust the left side a little depending on which way its feeding off. Unless its REALLY crooked then maybe 1 of your rollers isnt tight. Use all 3 rollers and make sure your not locked down in the middle where the white thing is showing you there is no roller.

Sure! I have attached two photos from the back view. I have let slack out of the roll so it is not directly pulling from the roll but this still is occurring. :/ Thanks for the help! :)

One of the problems judging by the first pic is that one of the rollers is adjusted a lot tighter than the other. Pressure should be as equal on both as you can get it.

Because many rolls of vinyl come pre-punched with holes on the edges, I highly recommend you retrofit (requires a bit of mechanical know-how) and give your cutter a set of sprockets.

Thanks! I adjusted the tightness of each rollers (measured to be sure they were equal) and am using 2 rollers only for the 12" vinyl. It is almost exactly straight now. Thanks so much for the help!!

Keep an eye on them, vibration will loosen them up. I actually had one of the tightening bolts fall out once. Lucky for me it fell into the catch basket.
