Hey everyone!
Doddy, I feel your frustration!
Have been thinking about buying spare parts for my router so that if something like this happens I have parts availible "on the shelf".

That beeing said my drivers are still working great.
I usually run my machine 30-50hours per week depending on how many orders I have.
Have noticed resonance on some occasions when I have been running 10-12hours straight and push the feedrates up to get finished.
But that just tells me that my normal speed is optimal 😁
