Having a filament jamming / stop flow type of issue. It happens at roughly the same height each time. The filament does bind and the hobbed bolt stops pushing it. The extruder does need a cold pull each time to get cleaned out but flows again afterwards. I can extrude 400+mm without issues. Try printing again, about the same height (about 1.5-2" height) it failed again. for the third time actually. I am now printing a low profile print job that has been successfully printed recently with this filament. Inland purple PLA, 1.75mm I have been told there is a website to send the .stl file to for verification that it is correct. This file has never been successfully printed. I would like to send this file off for testing while the current print is in process. Does anyone know where to go? All practices that result in a correct print in my world has been done. It is a new design that has been generated using Fusion 360 and the "make" button, which I am new to. I normally design in Autodesk and simply export the .stl Just trying to remove variables. Any words of wisdom?
