I have the same problem. Mine seems to be a problem with certain PLA filaments. When I am doing some prints, the cutter sounds like it is trying to hammer through the filament. On some filaments, it cuts like butter and on others, it hammers until it breaks through. Sometimes, it hammers until the thing times out. Because of my great luck, the printer will make it through about 9 hours on a print before timing out. In my case, the filaments having issues are the clear filaments. They are brand new and I have tried 2 different kinds. It would be nice if there was some way to resume the print. Sometimes, when the cutter is hammering away at the filament, I have to use my finger to assist the cutter.
I have tested the updated firmware version 21.10.27.0 and the problem still persists. The 110 error still occurs and the message even still says that the timeout was still after 2000ms.

Here is a new video. It also shows, both at the start and the end, that I am on the new firmware.
Upon further investigation a friend pointed out a difference in the cutter behavior between the early cuts and the failed one at the end.
During the successful cuts prior to starting the print the cutter rotates about a quarter turn and then rotates back. When the failed cut happens the cutter rotates about a half turn and then seem to hit a stop of some kind. The error appears immediately when the cutter reaches that extreme rotation.
It looks like the failure might be due to the cutter over rotating and hitting a stop and not timeout related at all.
This cutter behavior is the same in my original video and the one with the new firmware.

Hi Chris, can you please the Main PCBA and visually confirm if the cutter proximity sensor is 90° and parallel? If you could send a picture it would also help us visually examine if it's correct. These proximities are fragile and can easily bend/twist. We add glue to fix them in place but it could be that this board was not fastened properly.
If this piece is bent, you can simply correct it by hand, it doesn’t need to be precise.
However, if it is not bent then, can you please film the cutter wheel closer as it rotates? This can be initiated from the X-ray screen.
I apologize that we're asking for you to do this on your new unit, but we believe that there may be an issue with the Main PCB. If that is the case, we'll courier you a replacement immediately and cover the cost of parts + shipping.

I was able to find the sensor and confirm that is is glued in place and still in the proper position. I also posted close up clips of two more cutting operations. These are both from the same print, the first is a successful cut which was followed by a successful splice. This happened almost a dozen times and does so successfully up until the print actually starts. The second is the unsuccessful cut and happens on every print attempt on the very first cut after the step where the Palette instructs the user to start the print on the printer.

@thehammockguy Thank you for your help with this. We believe that this is an issue with the Main PCB. Would you mind e-mailing me (jonny@mosaicmfg.com) and we can either send you the board, or we'll return your unit to our offices, then ship you a new one.
