I meant clogged print core. We change them maybe every years on our 5 Ultimaker S5. Some of the print core were changed when they were obstructed and the others were changed when it didn't print properly 2/3 times in the row.

Okay, thanks. Then I'll check later to test a nozzle change, we have around 7/8 of them. Is there a restoration service or something similar to avoid the risk of breaking them?

Hello, We recently replaced the print cores on our Ultimaker S5. Some of the old ones have blocked nozzle. Is it possible to purchase the nozzles separately, or is there a restoration service in the EU?"
