Print Failure due to clogged nozzle mid-print #542
Description
Is there an existing issue for this feature request?
- I have searched the existing issues
Is your feature request related to a problem?
K1Max printing a gear resulted in following:
The AI Lidar worked without issues and produced perfect first layer, but during ~70% of the print the nozzle clogged likely due to too much of carbon fibres in PA6-CF partially clogging the nozzle
Which printers will be beneficial to this feature?

Describe the solution you'd like
Make an AI Routine that uses the red scanning laser during some sane intervals (ideally use AI to identify layers with an increased likelyhood for print failure and scan there + make it configurable) and verifies the print quality to pause the print if it detects any issues
Ideally make the printer deal with the clog by e.g. having a pressure sensor and dumping the problematic part of the fillament out to then continue printing
Describe alternatives you've considered
No known alternatives.. print finished as fail, the AI Camera didn't capture the failure (all stock parts), the same gcode before produced a perfectly looking PA6-CF part
Additional context
FreeCAD project include the exported 3MF files (used ./src/test-print4.3mf) and the project file (./src/k1max-calib-wheel-print-fail.3mf from orca-slicer, the file was printed using the UI touch screen display)
Acknowledgement: This happened on orca-slicer, but the gcode from creality-print vs orca-slicer seems to be nearly identical and this is more of an issue of better utilization of the AI Lidar than slicer itself.
This also seems to be an AI Calibration failure that is reproducible and doesn't happen if the AI Calibration is turned off, potentially due to the fillament being similar in the look to the bed, but more likely due to me doing screw tilt adjustment (which doesn't make much sense to me as the screw tilt should now be much closer to being flat despite the bed being warped out of the box)
