So my Robo R1 Plus printer stops extruding after an hour or so. I usually find it several layers above the print with nothing coming out and the filament grinded away by the wheel. Its usually a quick fix of unloading, cutting the end off and then reloading, but it is usually too late for me to continue my print. I don't know what is causing the issue to begin with. I have changed my spool holder to offer the least amount of resistance and have cleaned everything out.
