Coaster36 327 Posted April 8, 2012 Im need to this world, and I've been reading tons. I've been noticing my cutter leaving these little threads. Ive changed the offset all kinds I just cant figure out what is wrong. Currently its set at .03 in signblazer with the cutter at .25. Im using a used copan 2500. It has a new blade. The cutting strip is pretty beat up. But I dont know how that would affect the little threads. I beilve I have the blade set up correctly, When I cut by hand it cuts just the vinyl and no backing. And the pressure is 60 in the machine. Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted April 8, 2012 try 0.25 in Signblazer. Signblazer is what is telling you vinyl cutter what to do. Sounds like it's time to order a new cutting strip also. It has been said on here, that you can use a piece of reflective vinyl and put over your cutting strip to get by. Share this post Link to post Share on other sites
Coaster36 327 Posted April 8, 2012 0.25 in signblazer? That sounds really high. Well from what Ive read, I thought you wanted 0.03ish. Im going to try and flip the cutting strip over, hopefully the previous owner hasnt done that already. Share this post Link to post Share on other sites

mb20music 760 Posted April 8, 2012 I have a Copam and I use Signblazer, I find the best setting is the .25 on the Copam and 0 (zero) setting in Signblazer. Share this post Link to post Share on other sites
Coaster36 327 Posted April 8, 2012 I just did a few tests with 0.25 in signblazer and it was way to high. The corners were way off. Had the little triangle? at the corners. I have it set to 0.00 right now and the corners are perfect Its just leaving the little thread in the circles. Share this post Link to post Share on other sites
Coaster36 327 Posted April 8, 2012 Thanks mb20music.Do you get the little thread in your circles? Share this post Link to post Share on other sites
mb20music 760 Posted April 8, 2012 How small is the text you are cutting? does it only do this when you cut small letters/numbers? Share this post Link to post Share on other sites
mb20music 760 Posted April 8, 2012 Have you tried the different setting on the "Cut Direction" and "Cutter Movement" in Signblazer? Share this post Link to post Share on other sites
Coaster36 327 Posted April 8, 2012 Just tried them after you suggested them. Tried every combination. Doesnt seem to effect anything. Guess that leaves the strip causing the problem. Share this post Link to post Share on other sites
mb20music 760 Posted April 9, 2012 I bought my Copam used and it had some gouges in the cutting strip, so I smoothed it out with sandpaper, you might want to try that too. Share this post Link to post Share on other sites
mb20music 760 Posted April 9, 2012 What speed are you cutting at? you can try slowing it down to 10 and see if that makes a difference. Share this post Link to post Share on other sites
Coaster36 327 Posted April 9, 2012 It seems like the first time the blade goes down to start the letter its just off a little. Im cutting at 30, I can run it at 10 in the morning. Share this post Link to post Share on other sites
Coaster36 327 Posted April 15, 2012 After more troubleshooting found out that the problem seems to be an over cut. Heres what the cut preview looks like the line towards the bottom of the circle is the start line and the blade goes around the circle and ends at the upper line. Why dont they end at the same point? Ive tried up to 0.25 offset to -.02 yes negative. Is there a setting im missing? edit: Ok seems like when the blade comes back around, the vinyl isnt where is should be. Its off by a nats a$$.

Rodger 527 Posted April 15, 2012 Do you have any value in the Copam settings ? Use either the software or the cutter & have 0 value in the other . Share this post Link to post Share on other sites
Coaster36 327 Posted April 15, 2012 The cutter is set to .25 offset Share this post Link to post Share on other sites

Rodger 527 Posted April 16, 2012 I have the offset to 0 in SignBlazer & ..25 on the CoPam . I think the offset if the distance from the center of the blade to the place on the cutting edge where it actually cuts ?? Pressure & variations in the blade could require fine tuning , but I have never needed to . every blade package has the offset that is suggested . Share this post Link to post Share on other sites
Coaster36 327 Posted April 16, 2012 Could you give me your pressure setting for cutting 651? I think my vinyl might actually be moving to the right while its tracking. Is there a way to know how tight the pinch rollers should be? If its moving its so small that you cant tell while its feeding, Its the vinyl isnt where the blade thinks it should be.

Rodger 527 Posted April 17, 2012 I use 170 & add 10 grams at a time as the blade wears . I don't know about the pinch roller tension adjustment , but I pick the roll of vinyl up & make sure it is centered to what is pinched when sitting it into the holding rollers .

Coaster36 327 Posted April 17, 2012 Hmm your at 170 with a new blade? My blade must be way to far out. Im running 70grams right now. Ive done the test where you manually cut a piece of scrap and make sure its set good. I have to figure out whats causing those little ticks, why doesnt my blade end where it starts? Its driving me crazy! Share this post Link to post Share on other sites
Coaster36 327 Posted April 17, 2012 Just got off the phone with customer support, and the guy is thinking its the blade holder. He says the magnet inside gets worn out and lose. Not sure I buy it but itll at least fix my shuttering problem, hopefully. Share this post Link to post Share on other sites
