Back the truck up a second here
Not cutting that size doesn't make sense- I know... BUT- You have to eliminate ALL possibilities when you're troubleshooting. It still could be the file, could be a cutter memory issue, and it could be that it is needing to be spooled in pieces versus just dumped to the cutter.
Say I have a graphic with 1,000 nodes- 22x14. If I expand that to say, 500% - I still have 1,000 nodes, but their more spread out now- the file size goes from about 2.93mb to over 8mb.... Could be that the file, in that size, has too many nodes for the cutter to handle all at once, and the software needs to spool it a little at a time- OR the other thing I found a lot of the time with my old Laserpoint 24- It could cut faster than it could receive... so once it ran out of nodes to cut, even though they were still coming it would go crazy and do dumb things.
Things to try-
- Slow down your cutter - this can also effect tracking and placement of weeding lines and letters.
- Check or don't check "Use Spooler" under the cutter settings in SignCut
- Try that Keyspan device you have coming....
- Try cutting without your blade in, and also use a pen tool on paper to see if you have the same issue- Static can cause goofy mess as well....
- Before perfoming large cuts, shut the cutter off completely to clear out it's buffer, this helps as well on machines with less memory.
- They also make a memory upgrade for the MH series cutters- Seems to be that this fixes a lot of problems with this machine as well.
