I've been using my shopbot with a porter cable router for under 3 months now.
I've been noticing more sparks than normal and it looks like my brushes are shot.
I run it about 1 hour a day about 4 days a week or less. I'm cutting 3/4 particle board with a 1/4" bit. I'm doing 3 passes at 1.7-2.3 i.p.s.
Does this sound normal? I didn't think I was running it alot so I figured they would last much longer than this.
I'm not sure if I should take it my service center or jsut by new brushes?

BTW: Anyone recommend somewhere to by them from?
