My trusty 611 has run thru three sets of brushes and who knows how many hours of operation.
Today, I was messing around learning how to modify/mill step files imported in to F 360, cutting plastic. After multiple files and about a 6 hours of cutting I start hearing rock crusher sounds from the router, hmmmm, not good. Figured, oh well, let’s run to failure and see what happens, just practicing after all. Finally, it just quit.
Autopsy tomorrow, what do you think? Bearings are an obvious choice. We’ll see. Stay tuned.
