Just installed the micro SWISS all metal hot end. And I have an issue.
After printing about a layer or two, the filament gets ‘stuck’ for lack of a better way of saying it. To clear it I have to remove the pressure connector and , while hot’ ’ push the filament though the hot end. After that I am able to get the filament released
Even when the nozzle is hot, I am unable to pull the filament from the hotend trying to clear up the blockage
I hot tightened the nozzle etc.
What can be wrong?
