Hey guys, you might remember i posted up that id just bought a Foison C24 USB cutter from Ebay.

Im really pleased with it but i have a question that i hope you can answer.

When im doing small vinyl decals (Oracal 651), at some points on the vinyl the cutter hasnt cut completely round the letters.

This makes weeding a nightmare.

Is this likely to be a pressure problem that i can adjust or something else?

Thanks in advance.

Im not familiar to your cutter, however i would try increasing the force of the blade. Another option is if your cutter allows you to change the offset, try adjusting that if increased force doesnt work.

I will have a read of the instructions for offset. Thanks

I think the vinyl not being cut would need more cutting force, but also check the blade depth is adjusted to 1 mm . The formula is the thickness of your vinyl + half the thickness of your backing ( carrier sheet)= blade depth.I hope this helps and I wish you good luck. ..... JB

Theres nothing about offset, but ive just had a thought.

The cutting blade sits in the holder and in the instructions it shows you how to set the blade so that enough is showing and how far it should stick out.

Would it have this effect if the blade wasnt sticking out enough?

If that is the case, when cutting vinyl, should i have a score mark (not a cut) in the backing paper. At the moment its cutting the vinyl (maybe not quite enough) but not marking the backing paper at all.

Im guessing my issue maybe either a) cutting force b) blade length c) both.

Does that sound feasable?

I would say you are on the right track. ..... JB

yeah i can always see a score mark on my backing when its deep enuff..
so I agree with JB again.. lol..
you are on the right track

sometimes i think dull blade will do that too

If you do not have a offset control on your cutter you will find that in your software, sounds like it may be a combo of blade depth and offset

Your on it!

The cut should be just enough to cut through the vinyl and leave the score on the backing paper.

If you do not have a way to adjust force or offset, you will have to adjust the blade. I know mine if I want to adjust the blade itself, it sits on the cutter in a container which can be turned to move the blade further in or out for more cutting depth.
Most of the time on mine though I just have to adjust the offset.
So I'm a lucky one ;o)

Ive just dismantled the blade from the holder and found a 1mm square piece of vinyl surrounding the tip. I think that may have stopped the blade cutting to the required depth. Ive also lowered it slighty and will run some tests to see if i can get the backing to score.

Not alot of improvement, pulling away the excess vinyl on the outside is still pulling away the actual decal

Ive lowered the blade and increased the force. I'd like to adjust the offset but i dont fully understand what it is, how or where to adjust it.

Im using SignCut X2.

Any help appreciated. Thanks

In sign cut look at the menu, open settings , go to cutter, and there you will find offset it should be at 0.25 or 0.025 if you have a manual setting on your cutter set that to 0 it then will be controlled by your software, increase the offset until you get a smooth cut

Boro · July 9th, 2008

Thanks. The offset on the software is set to .30 at the moment. Should i set this lower or higher?

plan b · July 9th, 2008

try .25 make sure you have a new blade and zero out your machine if it has a machine set fo offset. are you sure its not 0.030 if it doesnt do things right check that #
