nose49 0 Posted October 21, 2009 I have a problem that I get a sort of blade chatter on most of my cuts with the laserpoint (small perforations as opposed to continous cuts). It does not happen to all the cut lines. but if I do multiple cuts of the same images it occurs in the same places on all images. Resulting in a jagged edge on those cuts. Anyone know how to fix this? Share this post Link to post Share on other sites
Dakotagrafx 7,297 Posted October 21, 2009 usually too much blade sticking out - should be 1/2 as deep as a credit card as a general rule to start Share this post Link to post Share on other sites
nose49 0 Posted October 21, 2009 Tried all positions with the blade. Blade just barely sticking out. I have put a small amount of oil on the blade to help with spin. Have changed pressure settings, speed, ect.. It has always been a problem . Sold refine mh721 to get this and made a big mistake. The machine only has about 5 hours use max since i bought it a year ago, because it just doesn't work. This is a replacement bladeholder that I'm using.

tekcorps 50 Posted October 21, 2009 What type brand of material are you cutting and what degree is your blade? I had a problem with black 651. Changed blade from 60 Share this post Link to post Share on other sites
Guest Posted October 21, 2009 Please upload pictures illustrating the problem you are having (pictures of the jagged/"chatter" cut). I also recommend starting a support ticket here: http://support.uscutter.com/index.php?_m=tickets&_a=submit Share this post Link to post Share on other sites
nose49 0 Posted October 21, 2009 I'll put the photos up in a couple of hours (soon as I get to my computer). I sincerely appreciate your help. Share this post Link to post Share on other sites
nose49 0 Posted October 24, 2009 Here's a couple of photo's of the problem. Thanks in advance for any help. I'm using SBE with an AMD 2.3GHZ dual core processor, windows Vista. Share this post Link to post Share on other sites
midwaste 4 Posted October 26, 2009 What is your pressure set at? I assume since the cutter is new, the cutting strip is in good shape, no major gouges or cuts? Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted October 26, 2009 Here's a couple of photo's of the problem. Thanks in advance for any help. I'm using SBE with an AMD 2.3GHZ dual core processor, windows Vista. have you made sure there is no pieces of vinyl in the blade holder, , is it spinning freely, have you tried adjusting offset.. Is that jagged cutting on all designs you cut? Share this post Link to post Share on other sites
nose49 0 Posted October 26, 2009 Cutting strip is in excellent shape. Spped makes it worse. I have checked the spinning of the blade in the holder, it seems to spin freely but is hard to tell when in operation. Blade offset is 0.00. Thanks Share this post Link to post Share on other sites
Jay2703 704 Posted October 26, 2009 Have you tried changing the blade? Share this post Link to post Share on other sites
midwaste 4 Posted October 27, 2009 Offset should be at 0.25 in SBE, but that isn't what is causing this problem, although it's causing the corner in one of the photos you posted, I believe. When you load your vinyl, is it flat all the way across the cutting strip? I noticed the chattering gets worse in the center of the cut, but isn't as bad at the beginning and the end. Where do you have your pinch rollers located? I think you still may have your blade out too far. Did you use the instructions in the Instruction Contribution forum to set it?

nose49 0 Posted October 27, 2009 The pinch rollers are about 1-1/2 inches in from the sides the vinyl is flat. The blade is just barely visible (~1/2 thickness of a credit card). I tried it with the blade out more, no effect on the problem. Share this post Link to post Share on other sites
Jay2703 704 Posted October 27, 2009 Have you tried a different blade? I thought I read one post where the baled had been machined wrong and trying a differen blade solved a similar problem. Share this post Link to post Share on other sites
midwaste 4 Posted October 27, 2009 Try it with the blade IN more. Dial the blade in until it is not even cutting the vinyl, then slowly adjust it out until it barely cuts through the vinyl.

Guest Posted October 27, 2009 Please post pictures of the same cut done with the pen attachment. This looks like a text book blade depth issue. Share this post Link to post Share on other sites
nose49 0 Posted October 30, 2009 I'll post those today. Great Idea. Thanks Share this post Link to post Share on other sites
sarconastic 29 Posted October 30, 2009 I have had this happen a few times. and it seems to be worse when it's cutting at an angle a certain way. I found many times it was too much pressure. Lp comes default to 120 for the pressure so you kind of work from that point, but what I have found is reducing the pressure to 90 then adjusting you blade so it cuts correctly seems to work a lot better. This also eliminates a lot of the alignment problems with smaller graphics since the pressure isn't causing it to pull as much. Kevin Share this post Link to post Share on other sites
