MZ SKEETER

I don't know why you would think a value cutter would come close to a Graphtec. Night and day cutters. So what is your problems? Besides saying it is junk. No one can help you that way. It takes time and patience to set up a value cutter.

Get your wallet out then and buy a Graphtec or a Roland. Most here use the Graphtecs. Most all value cutters come from China.

We have told buyers for years not to buy the MH cutter, and to step up to at least the SC2, It is a known fact that this cutter has problems, Static, tracking, connecting, You should read before you buy. The info has been here for years. Most any value cutter comes from China. Your post is nothing new that most people don't already know. So what is your problem? That cutter and any value cutter will run better on a Tripp-lite Keyspan adapter and a null modem cable. Posted 100's of times on here. Tripp-lite is the brand name. Destroying your material? Either static, or you don't have your blade depth set correctly. Posted here 100's of times. Blade depth has to be set correctly first.

So you were cutting over the groove that is for perf cutting, instead of over the teflon cutting strip?... Well, you never said that. User manuals are a great tool for new cutters. The user manual shows pictures and explains where the blade holder is placed for cutting over the teflon strip or perf cutting.

darcshadow is correct on the blade exposure. It is not possible to cut thru the wax paper backing, if blade depth is set perfect. No matter where it is on the cutting strip.

Fixed how? Incase another person has this problem.

Contact Graphtec tech support. Nothing more to add.

Add just a bit more blade.

Rule out the problem Cutter or software. Trying using another of Graphtecs software, or another trial. Never heard of a Graphtec cutter changing force in the middle of cutting. I own 2 Graphtecs. What type of vinyl are you using? What force are you using? What happens when you raise the force? If the blade is set correctly, it would not be possible to cut thru the wax paper backing.

No mention how you have set your blade depth. Too many incorrect instructions out there, saying to use a credit card or post it notes. That is too much blade Exposed out of the blade holder.. It really matters how much blade is exposed from the blade holder. This works. 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 tip out of the blade holder. Regular sign vinyl is only 2-3 mil thick. You only cut with the very tip of the blade. When you think the blade is so far in the blade holder, that you think it would not even cut, that is probably correct.

No, you would not replace the mother board. It's only like a $5.00 part. You have to get the number off of it and go to an electronics shop and get it. Or order online. UScutter no longer sells them . Unless you want to spend that kind of money for a motherboard.

This gets you to the motherboard, https://support.uscutter.com/hc/en-us/articles/360037533472-Replacing-the-MH-MK2-Motherboard The upper right corner is a search bar. Also Google search and youtube videos.

z chip is on the motherboard. Some places have photos listed on here. There have been several different boards over the years. I don't own a MH, But have read this problem many times on here. You could put z chip in the upper right hand corner search bar, many posts on the subject.

a fried z chip is usually the main problem with MH cutters, blade not going up and down. We see it all the time on here. They are very prone to static. There is a battery test that you can do with a 9 volt battery.

why did you think it was the carriage it's self? That sounds more like a fried z chip. Zapped by static. Hopefully you have the cutter grounded to the stand if you have one.

" i barely saw the marks in the backing paper" Means nothing, it is about how much blade is exposed out of the blade holder. You can get those same results "i barely saw the marks in the backing paper" with 10 times too much blade exposed out of the blade holder. The blade should be so far in your blade holder, that you would not think it would cut at all, and that would probably be correct. You only cut with the very tip of the blade. You use the force of the machine to cut with. Your UScutter SC is a Liyu cutter. How long is that rectangle? Look at the distance from the vinyl edge to your rectangle. Your photo doesn't look the same distance. It doesn't look like it is tracking straight to meet the lines. You should always have enough vinyl pulled from the roll and slack to do the order. Never be pulling from a roll while cutting. Slow your cutter down,

Your cutter is a Liyu brand. That looks like a tracking problem. Also too much blade exposed out of the blade holder could cause the vinyl to shift while cutting. Make sure your blade is set correctly and that your vinyl is feeding straight. No mention which cutting software, add a little over cut in your cutting software. 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.

When you think the blade is so far in the blade holder, that you think it would not even cut, that is probably correct.

If you didn't connect with a Tripp-lite Keyspan Adapter, and null modem cable, then you didn't upgrade at all on cables. Inexpensive USB to serial cables are pretty much like the cheap chipset that is in the cutter. Tripp-lite is the brand name and mentioned here hundreds of times as the upgrade to serial. Cutter needs to be grounded to stand if you have one. See if it does the same thing when using the pen tool, Static will cause freezing. Also those cutters have limited memory, Too many nodes will cause it to freeze up.

Have you tried setting your blade correctly like you should for vinyl? I wouldn't think it would vary that much. 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.

When you think the blade is so far in the blade holder, that you think it would not even cut, that is probably correct.

We don't know how large of designs you are cutting, those inexpensive cutters have limited memory.(too many nodes) Do the problems still appear using the pen tool? It could just be static from the vinyl. Did you ground your cutter to the stand? You can search the difference between the serial cables. Plenty of info out there.

Also, looking at your last picture, Am I seeing right? Are you putting the vinyl roller thru the vinyl roll tube? The vinyl roll should be sitting on top the 2 vinyl rollers normally.

The Tripplite Keyspan IS NOT supposed to fit on your cutter, As I stated, it needs a null modem serial cable between the Tripplite and your cutter. . I would have no idea whether your cutter cable is just a straight serial cable or a null modem serial cable. They are different, wires are crossed in a null modem cable. The cable does not need to be long.

That is just a USB to serial adapter, not a Tripp-lite Keyspan Adapter. Tripp-lite is the brand name . You need a null modem serial cable to connect on the pin side of the Tripp-lite Keyspan adapter, then connect the other end of the serial cable to your vinyl cutter. Then the USB end of the Tripp-lite Keyspan Adapter goes into your USB port of computer. Download and install the driver for the Tripp-lite Keyspan Adapter. Reboot your computer. It will show up in your computer device manager (This) adapter may or may not work, as most inexpensive adapters have the same cheap chipset as value cutters, and you are not fixing anything. Below is the Tripp-lite, find the best price. Longer cables are not best. You may have received a serial cable with your cutter, see if that cable will work. https://www.amazon.com/Tripp-Lite-Keyspan-High-Speed-USA-19HS/dp/B0000VYJRY/ref=sr_1_3?crid=10D0G0A7UNHS&keywords=tripp-lite+keyspan+adapter&qid=1650482086&sprefix=Tripp-lite+keyspan%2Caps%2C274&sr=8-3

less than a couple minutes. I use needles, they come right out. I use needles everyday, when I weed. Very handy, right there in my pin cushion.

In 6 years you should have gotten your monies worth out of it. If it is in your budget upgrade to a servo and go on with life. Time is money.
