Shane Quale 5 Posted September 4, 2020 Hello Friends, I've got an issue that I am trying to resolve. I am using the USCutter MH871 cutter with USCutter 60 degree blades and the UCutter blade holder as well. My issues I am having is the letters in the middle are being picked up by the blade and it will not cut a full perfect circle so my lines are off. I've also got squiggly lines as you can see in the picture. Any suggestions? I am using Oracal 651 vinyl. You can see in the picture to exactly what the issue is. I can cut one decal perfectly but when I switch to a different decal its all goofed. What force/speed do I need to cut at? I don't know.... Any help would be greatly appreciated.

MZ SKEETER 4,708 Posted September 4, 2020 search for setting blade depth. It's been posted hundreds of times on here. When vinyl is lifting, you have too much blade exposed. Slow the cutter down. 2 Share this post Link to post Share on other sites
Shane Quale 5 Posted September 4, 2020 Ok I will give that a try. Thank you. Some of this issue to is if I cut a square, the corners are not at 90 degrees. Sometimes it will complete 3 of the corners but the other will be way off. Thanks Shane Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted September 4, 2020 Correct blade depth is first to do, then your blade offset. Start at 0.25 mm then adjust 0.05 plus or minus Your welcome. 1 Share this post Link to post Share on other sites
haumana 1,220 Posted September 4, 2020 make sure there is sufficient slack on the vinyl for the entire job to cut. slow the cut speed down. 1 Share this post Link to post Share on other sites
Shane Quale 5 Posted September 4, 2020 Ok so I got the speed set to 24 and the force to 120. The blade adjustment is now way better. I still have slight jagged lines but barely noticeable. Also I have roller marks in the vinyl so an adjustment is definitely needed there. Thanks Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted September 4, 2020 Roller marks don't hurt a thing, the marking is caused by the grit roller on the bottom of the wax paper backing.. They come out when you apply the vinyl in most cases. You start creating other problems when you go adjusting the pinch rollers. 1 Share this post Link to post Share on other sites
haumana 1,220 Posted September 4, 2020 you can check your offset and see if that will help. 2 Share this post Link to post Share on other sites
Shane Quale 5 Posted September 5, 2020 Thanks guys! Very helpful. I will give some things a try today. I didn’t expect it be perfect being a value cutter but I think I can get some nice work out of it. Thanks again. Shane Share this post Link to post Share on other sites
Shane Quale 5 Posted September 5, 2020 Attached is my better of the ones I have cut and did test runs on this morning. Its pretty decent for me so to speak. You can see in the decal where the 2 props on the left are thinner that the 3 props on the right. Also, some of the cuts are slightly rounded but really not too bad. Its going on a model airplane so being perfect isn't a must but I will try and learn to make cleaner things down the road. Share this post Link to post Share on other sites
