I tried a new blade with no luck and tried the test cut. It sort of hung up in 2/3 cuts in the corners of the box. I'll take the cover off in a bit and see if I see anything, thanks!

I have an MH871-MK2 and it has been working flawlessly but in the past day I have noticed cuts becoming weak. I have adjusted the blade numerous times and tried a new blade all together. Even with the blade all the way down, it still won't cut smoothly. It cuts the design fine but weeding it is difficult, especially on smaller things. I even bumped the cut press to 120 with the blade maxed out and it didn't help. I have a project due this week that needs to be done right so I'm hoping it's something easy....any ideas? Anything to check? I noticed some grease on the case, could something have broke? Like I said, it still cuts, it still looks like it's doing its job, it just doesn't seem to cut smoothly through the vinyl which is why I am worried maybe whatever controls the press could be broke? Thanks!

Sounds like my issue, it just goes straight and scratches the vinyl and goes all the way until the end of the cutter? You did use serial cables?

Yeah I sanded the paint down right there. Cool thanks! I'll get one those two.

Running USB, I'll try to find the adapter but it's weird that it just now does this. Ground is fine, very small decals, like 4 inches long.

So my MH871 randomly cuts fine, then halfway through a project just goes straight horizontally to the end of the cutter and stops.....any one else seen this or know what to do to fix it? I've also noticed randomly on this design I cut it will cut fine, now all of a sudden it can't seem to get the bottom of the image straight, it cuts it, but it's offset but only at the bottom of the picture the rest is perfect.

Gotcha, thanks!

How freely should the feed rollers spin by hand on the MH871? Having issues with my unit (hehe) and am just trying to cross everything out. US Cutter is sending me a new blade housing/box/cartridge thing but I'm still double checking everything.

Well I went ahead and took that cover off, nothing is visibly loose. :/ I'll double check everything is tight.

Although mine is still acting up I did have the jagged line issue and also turned the speed down and got very straight lines from that.

I just saw this, having same issues, going to try that tomorrow although they're sending me a new box.

Quick question while I wait. How smoothly should the feed roller spin? It spins but there's a bit of friction. Reason I ask now is because after talking on the phone with them and they mentioned it could be the rollers I played with the blade holder more and no matter how loose or tight I have it, it shows the exact same result. I didn't know if the rollers could be screwing it up, my straight cut lines are perfect, it's just corners and what not that show issues. So. Frustrating.

Got in touch with them, they're going to send me a new cartridge piece to solder in and see if that fixes it.

Yeah I shouldn't have said that, I didn't torque it down or anything, just as tight as I imagined to be safe for that plastic.

I brightened the image a tad...notice how the two pieces of the holder don't meet flush? I did contact tech support, waiting on a reply, sent a few photos as well.
