Print Failure Detection Idea

Just had my first serious print failure. The print lost adhesion to the bed and the print head was dragging the print around. It knocked off the Front Housing, which immediately canceled the print job. A very good thing.

So it occurs to me that if you put some “whiskers” around the bottom of the Front Housing, they could be used to intentionally knock the Front Housing off when you have (some) print failures, including spaghetti. I am thinking like 4-6 1" long whiskers about like a paper clip, that extend in all directions from the bottom of the Front Housing. Just above the print level. If anything cough one of those whiskers, it would knock the Front Housing off and immediately stop the print.

This would certainly not catch many of the types of printing failures. But it might catch some of the more serious ones.

What do you think?

There wouldn’t be that much space because the printhead moves to the very back (while changing and (un)loading), the very front (while cutting and homing), the very left (while cutting) and the very right (while homing). I do think this idea could work, but there probably isn’t enough space to add these. Also, what happens to print-by-object? The clearance would have to be greatly increased. I’m not trying to attack your idea by any means, but I am just explaining my opinion on why this is not feasible. Very unique idea though!

Sorry but this is not a good idea. The print housing is not meant to be knocked off and the connector can get damaged. (I know from experience). This would also not catch spaghetti failures and I honestly can’t imagine what type of failures this could catch? When a print falls over due to lost adhesion it’s lower then the nozzle height.
