RE: Core One: How does the side filament sensor work?
Absolutely yes, the side filament sensor should have stopped the print.
You may have noticed that the printer shows you the status of both the side sensor and the head sensor in the display. So you can verify that the sensors are working every time you add a new filament.
If your sensor is not working, perhaps you have the bolt a bit too tight on the lever arm? We have a lever arm, it is held apart with the magnets. When a filament is shoved in, it moves the level. The other side of the lever is between an IR sensor. The tip of the lever gets lifted out of the gap between the IR sensor - that changes the signal.
Should the side filament sensor have stopped the print?
RE: Core One: How does the side filament sensor work?
How do I know?
Cause I am printing the Lighthouse without Bench sample print. I just ran out of filament one hour ago. Yes, the printer stopped when the side filament sensed that I had run out of filament.
It was a bit difficult to swap the filament out because I accidentally broke of the tip of the filament that was sticking out. But we got it sorted and the print is continuing. Wow, just twelve more hours to go on this one !

RE: Core One: How does the side filament sensor work?
That (a menu option) does not seem to be an option.
The printer menu seems to be set in the 'please change filament mode'. I did not see a 'unload the filament a bit so I can get to it'. Presumably the printer already automatically did that.
So I was also reduced to: opening the tensioner; removing the tube from the head; pulling out the filament; etc.
Was that after you let the printer "unload" the filament via the menu, i.e. let the extruder push the filament back?
RE: Core One: How does the side filament sensor work?
They do cover this in the instructions. I believe it is mentions to move the level manually to ensure it moves smoothly and is not binding anywhere.
They let you check that the lever moves freely while the lid of the sensor housing is still open. (Mainly confirming that you have not overtightened the pivot screw.) But the problem @marino-2 refers to will only manifest itself once you mount the lid:
The magnet inserted into the lever is a mm wider than the lever itself. If the magnet sticks out too far at the top, it will rub against the lid. Filament insertion may become more difficult, or the lever may get stuck in the "I see filament" position.

Ah, OK. I did notice that when I was assembling the C1+ version. In hindsight though, should have stuck to what I had before.
It's an odd design to begin with. Especially since they could have used smaller (and weaker) magnets from the beginning which would have solved the issue with feeding in softer TPU's.
