It was flowing previously but restricted unbeknownst to me. I'm thinking retraction to pull back material worked but it couldn't push it back due to blockage, not as much as needed, therefore pulling the filament back more than it pushed forward in total. PTFE tube was previously %100 in but why it was partially out now, I don't know. My problems are probably %100 mechanical. | |

You should address the retraction at the end, or load more in your start. You can also consider priming, e.g. Cura uses a blob & swipe on my Ultimaker 3E. | |

I print a single priming line my my custom start gcode with just 18 mm of filament, and it works fine provided the filament is properly loaded to begin with and not left retracted at the end of the previous print (I unretract to just a net -1 mm in end gcode). | |
