A few months ago, I posted here:
And explained that we were having a lot of trouble cutting ALL the way through draftboard.
We spent a lot of time and effort on cleaning things, including the lens, with Zeiss wipes, buying magnets, etc.
Also discovered the four dimples under the crumb tray and cleaned those. Worth it. But it didn’t fix the problem.
It turns out that there was a tiny piece of cruft in the hinge on the top. That cruft wasn’t big enough to keep the top from closing, but it was big enough to cause a tiny rift in the time-space continuum when the lid was shut. That tiny flex was enough to cause the problem.
Still in favor of the machine being smarter about it, but it’s a relief.
Wanted to share here in case anyone else was also frustrated.
