Occasionally post print my printer will do silly things after seemingly printing successfully such as stopping immediately and saying “Wait for user input” while the hot end melts the print (no turning off of heat, homing or kicking out of the bed). Worse (and fortunately less common) is the dreaded Z axis drop. I just printed a calibration code and upon completing the hot end just torpedoed straight into the print which broke the print, got melting ABS all over the hot end, made one Z threaded rod change position significantly and of course hosed the bed leveling.
Note I do have a computer connected via USB with Pronterface running (but not monitoring) that I use for manually moving the hot end around and more commonly manually extruding to allow picking out the grooves in the hobbed bolt.
Any ideas? The end of the aforementioned code is below…
