I live in Denmark. I don't have CNC routers but lasers both for cutting wood/plastic and metal. There are a couple of reasonably active Danish CNC groups on Facebook.

Here is one of them: https://www.facebook.com/groups/1597095953896634/

I'm the admin on a Danish FB group for laser cutting: https://www.facebook.com/groups/169628966917341/

There is no duty imposed on the shipping fee but sales tax (VAT) is and the rate in Denmark is 25%. We get by OK though - health care and education is paid for through taxes so no one has to worry whether they can afford to get an education or receive treatment.
