CX-400 problems

[Guest 7m34life]

I currently use a Roland CX-400 plotter to cut my film. The plotter has worked fine until about 2 months ago I didn't pay attention to how little film I had on the roll and it sucked to plastic roll up and hit the head and jammed the machine. Now when I do longer cuts around 50"-60" it will feed about 3" out and jams and says power off error. I can get around that by going ahead and feeding out how much film I'll need and feeding it back in that way it doesn't have the tension of pulling it off the roll. This morning I went to make a cut with it and it keeps on getting my film wadded up and tearing the film as it's cutting. I run it on 15 cm/s and 120gf on the force just like I always have. The only thing I can think of is last night I was wiping it down and might have moved the manual pen force adjustment on the front of the machine. I did make several test cuts while adjusting the pen force but it's steel screwing up my film. I've already wasted around $100 worth of film by trying to figure it out. Any help would be appreciated.

What settings do you run your plotter on??

THANKS

you can try adjusting the speed of the knife also the offset speed which is when the knife is in the air... do you still have your manual if not write me a pm since I still he mine somewhere lol...

Does it give you an error code?

you can try to do a master reset on it. See if it clears it up . hold down left arrow, right arrow, origin and power on. It will prompt you to reset eeprom, press enter. You will have to cycle the power and then reset all the force and speed. This factory defaults the machine so all the parameters are reset.
