I am printing with PLA+ at 225C I have had some successful prints. Recently last couple days I have not been able to finish a print, the extrusion stops in random places typically within the first 2 hrs, but once close to the end of the print (~13hrs). After a failed print and removing the material I do see where it has been ground by the extruder motor. I am using retraction, but it is set to 2.5mm min travel so the retraction does not happen that often. One time it stopped cold with a temperature sensor error. I am thinking that my nozzle temp may be cooling and the material is jamming. Any ideas.
