Jane a bit more detail would be useful to try and sort out your plotter problem. What plotter are you using, what software are you using? and what sort of vinyl are you trying to cut?

Could be down to a number of different things or a combination of things so some more detail will help narrow it down.

Are the 2 rollers that push and pull the vinyl through positioned correctly?

quote Warren Beard:

as warren says, are the pinch rollers in the correct place? ie, does the vinyl track correctly when you load it? this will cause the vinyl to run out of line and slew off track.

i would hazard a guess, and say the blade is cutting too deep, and/or maybe too much pressure. this causes the blade to cut right through the vinyl and the backing paper, making the vinyl ruck up, catch on the blade holder, and tear.

Pinch rollers, that’s it 😮 for the life of me I could not remember that when posting the reply :lol1: :lol1: :lol1:

lol, i forgot a good pals name the other day when introducing him to some old mates, how bad did i feel!!

i’d be glad to forget a technical term over that!

The Model of Plotter is a Mimaki CG 60SL.

Yes it does have pinch rollers

Software: Fine cut 7 CS3

The Vinyl is Easimark Cotton

The rollers are positioned properly, yes

I will explain in depth
The vinyl loads fine, the cutting starts fine and cuts as it should do but then it appears to start cutting deeper as plotting progress’s. At that point I have to switch the unit off.

ok, different machine to me, but generic problems!

i’ve had a similar problem in the past, it’s normally associated with me using the end of a roll, especially on something like a thicker vinyl, carbon, etc, as it’s rolled tight on the roll, it can tend to hold a memory which makes it lift a bit when it comes over the cutting strip, causing the blade to cut too deep, …….

the other is sometimes that the roll holders (i have two wheels which insert into the tubes) are not 100% straight, the vinyl can sometimes try to ride up as it comes through the plotter,

reflective gives me the biggest headache, as it holds it’s memory very well, i find it best to lay it out on the bench the night before, it’s alot easier to use then.

i still think your blade might be too deep though, it shouldn’t be able to cut through if it’s set at the right depth.

what pressure are you using on the blade? i find about 90g is perfect with a new blade, on most vinyls, it might be you’re using too little pressure and too much blade, you might not be, but worth a double check,

these problems are normally something very simple and we scratch our heads for hours, looking for a technical answer!

Thanks Hugh.

I think it was a pressure issue with the vinyl pulling as it was cutting. Many thanks

[Hugh Potter]

glad ya got it sorted.

i guess i should have added that it cold also have been too much pressure! oh well, all is well now.
