jongger 0 Posted July 28, 2015 Hi I wonder can anyone help. I recently bought a US Cutter MH 871--MK2. I have been trying to get the blade settings right. I have done loads of test cuts.My problem is the machine cuts deeper on the right side and in the left side (under the control panel) won't. So I can get the setting right but then the cut is to light on the Left side. Hope Here are some pictures of what I mean Vinyl https://www.dropbox.com/home/Plotter?preview=IMG-20150728-WA009.jpg https://www.dropbox.com/home/Plotter?preview=IMG-20150728-WA004.jpg teflon cutting strip https://www.dropbox.com/s/7j2gtvcqoo3ahym/IMG-20150728-WA010.jpg?dl=0 https://www.dropbox.com/home/Plotter?preview=IMG-20150728-WA003.jpg Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted July 28, 2015 Make sure that the carriage head white wheels are firmly down in the track... No dust in track Make sure teflon cutting strip is down all the way across your cutter. Make sure blade holder if firmly secure in carriage head. Make sure nothing like vinyl pieces inside the blade holder Set your blade correctly like this. 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.

MZ SKEETER 4,708 Posted July 28, 2015 Is this a brand new machine or a used machine? And what cutting software on what type of computer? And how are you connected to the computer? Did you check everything above like I asked? Especially the white wheels firmly down in the track from the carriage head. Post some pictures of the wheels in the track and carriage head. Does the carriage head move smoothly left and right in the track without raising or lowering.? If not,, it then contact tech support. What vinyl is that? It looks like crap... And why are the ends of your cuts not meeting? Why are the corners not sharp and square? What's with the jagged cut at the top of the 3? Backwards s and a look horrible.

Wildgoose 4,200 Posted July 29, 2015 Looks like you have a real mess going on there. You should not be cutting through the vinyl and into the cutting strip EVER. You will have to replace that strip to get good results. I don't know my way around the MH model but perhaps you can move the zero point over past that groove and get some cutting done on the strip where it isn't ruined. Just from what I see you probably have way too much pressure and by the depth of that groove WAY WAY WAY too much blade out. I am betting your blade tip is broken at this point too. If you know how to move your origin point over and set it farther over you can try again. You should install a new blade and adjust the depth like skeeter said so that it actually can't cut through the carrier even if you wanted. Then dial the speed down, not to the slowest but about 1/4 of the total available. Set the pressure very light (similar to the speed try 1/4 of the total available or somewhere around 60 grams) and start making test cuts one at a time while slowly raising the pressure until it will just cut through the vinyl. This may take you 10 or 15 tries. I don't know if the MH has a test cut feature. If it doesn't then make a small 1/2" square and maybe put an x in the middle to help determine if you are getting a good cut and then cut that file as a test cut. (try attached file) This all assuming your carrier head is on the rails etc.... Test Cut.svg Share this post Link to post Share on other sites

Sure now I'll post some pictures of the white wheels Does the carriage head move smoothly left and right in the track without raising or lowering.? If not,, it then contact tech support. Does not move smoothly to left side and the right side it moves smoothly. Share this post Link to post Share on other sites
slice&dice 2,450 Posted October 16, 2015 I'll chime in here ---- the MH model is familiar to me like the back of my hand. FIrst thing, of course, is to simply REVERSE that cutting strip. Peel it off, swing it 180* (right to left, left to right) and press it back on. That will leave a clean surface under the carriage head, and that ripped portion will be off to the far (left) side, perhaps beyond the width of media being used. Also, remove the cover on the left side (power plug side). There are just four screws holding it on. You'll see a tensioner arm with a roller and the belt spins on that assembly. You might try to adjust the screw and add (or subtract) pressure on the belt to see if it gives a smooth track all the way across. The last thing I'll mention, is for you to give a ring to USCUTTER and request they provide (please, pretty please) an opportunity to receive the BUNDLED software that is being shipped currently with machines --- VinylMaster CUT version. I got that a few weeks ago, it quickly loaded and displayed and synced to my MH machine, and runs that cutter like a champ. I recommend it to anyone who got SCALPed, and I hope USCUTTER management makes good to their loyal customers and gives a way for those using SCAL to 'upgrade' into VinylMaster easily and without exhorbitant costs.

Sumz 0 Posted October 23, 2016 Hi, i have a problem with the carriage, it's not in the track. Its been like that since i got it about 6 years ago. I didnt realize it till today. Its leaning againt the track, and I've been running it like that forever. I don't know how to put it back on...there's no room to just push it in. Also, i was wondering if i needed to place the blade holder into the groove on the carriage arm? Or just on top? When i place it on top, i have to push the blade out all the way...and somehow its not even reaching anymore. Share this post Link to post Share on other sites
