I have here a completly clogged core. For details, look at the pictures.
Hot/Cold pull does not help (or is not applicable). Probably because the nozzle is clogged and the upper part is blocked somewhere inside.
My idea would be to drill a very small hole into the upper part of the material and try to pull it out this way.
Is this the way to go, or is there another? Had someone similar situations? I thought about unscrewing the core, but stopped in between. I guess I wanted to ask first.
Any help is appreciated!
