Maybe you missed his answer in the clutter I asked the question above Is this a new cutter? They replied. "No, it's been working for 5 years, but other than that, it's perfect." "Hello, the cutter has been working OK, just some random day, it wouldn't cut" Share this post Link to post Share on other sites
darcshadow 1,640 Posted August 19, 2020 Thanks, yeah, missed that one. So then the question is, did something happen/change before it stopped working? Share this post Link to post Share on other sites
darcshadow 1,640 Posted August 19, 2020 Another question, with the cutter turned off, if you put a bit of weight/pressure on the arm can you get the blade holder to touch the cutting strip? the 5 years you've used it, have you always had to have the blade sticking out so far, or is this a new development?

darcshadow 1,640 Posted August 19, 2020 I took the cover off my carriage and don't see any thing obvious that could fail and cause the blade holder not to drop all the way. If you're sure the carriage is on the rail correctly I would take the cover off and see what you see. There could be something causing the arm not to move freely like it should. For reference here is a photo of mine with the cover removed. Also, fyi, with the blade holder out, there is even more travel in the arm and it can go lower. 2 Share this post Link to post Share on other sites
haumana 1,227 Posted August 20, 2020 You might consider changing your cutting strip, because it looks kind of slashed up. Share this post Link to post Share on other sites

Clearly there's a position problem as the blade holder should be touching the cutting strip when the cutter is turned off. I'm not near my cutter right now but when i get a chance I'll look at mine closer and see if I can see anything that you could adjust or account for the extra height you're seeing. Again though, has this cutter ever worked for you? Or is this a new problem? Hello, the cutter worked for me fine until that problem. At least 3 years, no problem. This is last year.

Hello, no, before the problem, the blade barely showed. And the cutpress was always set on 90~120 aprox. Just someday It wouldn't cut hard enough. Share this post Link to post Share on other sites

Take the carriage head cover off, as he mentioned. See what is keeping the arm from coming down. Show some pictures of the inside of the carriage head.

Hello, no, I just came to work, put a sheet of vinyl for a car decal, and It just wouldn't cut it. Just left the mark, but didn't go through the material. I changed the blade, but didn't work. And so and so. Could be a board problem? By the way, here's the new carriage. Share this post Link to post Share on other sites

darcshadow 1,640 Posted August 20, 2020 In that last photo, is the cutter turned on? Ok, I think I missed that the problem started, you replaced the carriage head and it didn't solve the problem? So I think we're looking in the wrong location. The problem just about has to be the rails the head is riding on. Share this post Link to post Share on other sites
kmorenor 0 Posted August 20, 2020 Hello friends, thank you all for your replies, I'm still working on the cutter. Send you a video so you can see what happens. Bye. VID_20200818_174438.mp4 Share this post Link to post Share on other sites

They seem to be well leveled, well lubricated, I clean them often. Share this post Link to post Share on other sites

Its too low. No matter thah it's set on maximum. Share this post Link to post Share on other sites

It's not that your pressure is too low, it's that the holder is not dropping like it should. When the cutter is off the holder should drop and be resting on the cutting strip. Something is causing it to sit too high. In that photo it also looks like the belt is not parallel to the surface, like the carriage is sitting too high.

I compared them and they're the same size, they fit in the rail. And I asked for a MH 871 MK and that's what arrived. Share this post Link to post Share on other sites

Hello, both the old ant the new one fit in the rail the same way, I checked, both sides of the rail and the screws are real tight, wouldn't know what could cause the carriage to be higher than it should.Does any of you help with a manual of how to dismantle it?

darcshadow 1,640 Posted August 21, 2020 Far as I know there's no manual for taking it apart like you're talking. I'm out of ideas at this point. Sorry and good luck. Share this post Link to post Share on other sites
