lucaquick 1 Posted February 24, 2021 I solved the USB Driver problems! BUT NOW i have a new problem!!! When I cut the vinyl the lines are very croocked!!!! I think the problem is the offset Is it possible resolve this? The range correct for offset are from 0 to 1, inside the software it's set on 0,25 What can I do to have a correct cut?

MZ SKEETER 4,708 Posted February 24, 2021 show pictures. You have to set the blade depth correct first, and then the blade offset. Use the TEST feature on your vinyl cutter. To start with, you should set your blade depth correctly, by taking the blade holder out of the machine, and firmly cut across a piece of scrap vinyl, you will be cutting. You should only be cutting the vinyl and barely a mark on wax paper backing, Adjust blade to get there, Then put the blade holder back in machine, and use the force of the machine to get there, same results, only cutting the vinyl and barely a mark in wax paper backing. You should barely see and feel the blade out of the blade holder. Regular sign vinyl is only 2-3 mil thick. You only cut with the very tip of the blade. 1 Share this post Link to post Share on other sites
darcshadow 1,626 Posted February 24, 2021 Also, offset only effects the corners of a cut, not the line itself. As Skeeter said, get your blade depth set correctly and if it's still doing it post a photo or two if you can. 2 Share this post Link to post Share on other sites

darcshadow 1,626 Posted March 3, 2021 If your blade is set correctly and your corners are still being rounded then it's time to start adjusting the offset. Share this post Link to post Share on other sites

lucaquick 1 Posted March 4, 2021 I send the test result. The first and second starting from the right are with the cutting tool installed in the rear position of the plotter the others are with the toll installed on the first hole of the plotter they look the same to me. The second photo show the difference between the pen tool and the cut tool both of them with the tool in the first front hole with pen is better Share this post Link to post Share on other sites
darcshadow 1,626 Posted March 4, 2021 That test cut looks really bad. The test with the pin looks better so that would indicate you have a problem with the blade or the blade holder. Inspect your holder arm closely and make sure there are no cracks. It's easy to tighten the arm too much and crack it which would then allow the blade to wobble. Have you tried calling tech support? I think that's were we are at now, not sure how much more the forum users can help. Share this post Link to post Share on other sites

The holder arm is the same for cutting tool and pen tool, there are only two holes for instal the tools Why with pen the looks is better? Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted March 4, 2021 Did you ever adjust the blade offset in Signcut? A pen will be zero offset. A pen does not drag like a knife. Can you show a pic of the blade sticking out of the blade holder? Share this post Link to post Share on other sites

I tried put 0 offset or 1 offset but the result look similar! which one blade is better 30°/45°/60°? can it depend on that? or can depend on the position of the tool? or there is a programme better for adjust the offset?

MZ SKEETER 4,708 Posted March 4, 2021 Blade offset should start at 0.25mm, adjust at 0.05 plus or minus. Til corners are sharp. Show picture of the blade sticking out of the blade holder, that might help. Biggest problem with people setting up a vinyl cutter, is they have too much blade exposed out of the blade holder. That must be set correctly first, or other settings. will not be correct. That blade should be so far in the blade holder that you think it won't even cut. You should barely see or feel the tip. It's less blade ,more force to cut correctly. Share this post Link to post Share on other sites

darcshadow 1,626 Posted March 4, 2021 One of those holder spots is for the pin and over hard plastic. the other is for the knife and over the cutting strip. I forget which is which. I think the one you have the blade holder installed in the photo is the one for the pen. If that is the case you've very likely broken the tip of your blade.

MZ SKEETER 4,708 Posted March 4, 2021 In front is usually the pen, If it's over the teflon cutting strip, then it's the blade. Try backing the blade in further until it can't cut. Then bring out just a tiny bit. Use more force to cut. Share this post Link to post Share on other sites
lucaquick 1 Posted March 4, 2021 i partly solved and improved the problem! see the result in the pictures! I removed the front plastic case, and tightened all the screws well!
