jclarke88 4 Posted January 4, 2015 Hey all, my name is Jordan, I am new to the forums here, so if this belongs in another place, forgive me and move it to wherever. I have a type MH721 that I bought used a couple months back, and it's worked off and on since I got it. It's frustrated me to the point that I'm tired of trying to figure it out on my own. First off, about a month ago is when it quit doing its job correctly. It's like it was going too fast or something because it was cutting through the back of the vinyl and the paper that the vinyl comes on (forgot what that is called haha). It would pull the letters up off of the roll it was cutting so fast/hard whatever the problem may have been. I renewed my subscription to signcut, the program I'm currently using, this month and I switched out the blades (put the 45 degree blades in) then tried to cut again. I also had slowed down the cutting speed and force because I figured that would help, and it did, or so I thought. It had cut through the vinyl but not well enough to where it was easy to weed out. So I piddled with blade height settings, different vinyl, yada yada yada and am still coming up with the same problem. In addition to this, I've also had random encounters with the blade being drug across the vinyl during a pass, which has not affected the final decal because it does not go through the vinyl, but it's like it doesn't bring the blade all the way up between each letter when cutting. So I guess my question is how do I fix it? I've tried about everything under the sun, but it seems like I'm taking one step forward then two steps backwards. I can try to tell you guys as much as possible in order for you to help me. The vinyl I used the first time around was white, most likely Oracal but I would not know because this vinyl came with the cutter. The second go around I tried black, and it was made by Arlon, and it was not easy to peel/ either. Then, because I got tired of wasting vinyl, I tried some scrap vinyl (yellow), which as one can imagine, worked about as good as sunglesses in the dark. I can also tell you the current settings of my cutter, which I don't really know how they got there because I didn't think they were the default but the speed is currently set to 12 inch/s and the force is at 00g. I don't know if that's something that the computer could have screwed up or what but it doesn't seem right. My baud is 9600, which i think is what it goes back to each time you reset, but earlier I tried setting it at 4800 because that is what the instructional video on here told me to do. Correct me if I'm wrong but I think it's also required to change those settings each time in SignCut as well. I can also provide pictures too if need be; I'm sure they would help but I've got other things to take care of right now so I will provide them as needed. It would be much appreciated if any help is provided because I have a job coming up soon and I'd like to ensure quality and customer satisfaction. Thanks!

MZ SKEETER 4,709 Posted January 4, 2015 I am only going to tell you how to set your blade depth correctly.. And each brand of vinyl can vary, so you need to check the blade setting each time. But most vinyl only varies a little bit, So you don't change your blade setting for those variations. You just adjust your force, and do the test cuts... 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. 1 Share this post Link to post Share on other sites
Jburns 239 Posted January 4, 2015 After adjusting the blade as Mz skeeter said, if it still drags you probably need a new carriage. I had the same problem once, and this solved it. http://www.uscutter.com/US-Cutter-MH-Carriage 1 Share this post Link to post Share on other sites
