New experience today. Filament stuck, will not withdraw from the print head.
I have been trying to do a print using Innova 1800. It prints about the first 15 layers, and then the filament grinds, and no longer feeds. This happened four times. I did a bunch of cold pulls to make sure the head was clear. Then tried again. Same thing, it printed the first 15 or 20 layers, and then grinds and that’s the end of that.
But this time, the filament will not withdraw from the hot end. I heat it up to 240, release the idler, and I can lift the entire printer by the filament and it will not pull out.
Any advice on how to proceed?
