I only have time to carve in the winter months and am getting a late start. I sent in my machine last summer for LHR to do a major service. Repair and replace anything they see that seems like a good idea as well as all available upgrades.

When I got it back, I did one small project as a test and everything seemed fine. Now, I am ready to make some signs and have a big problem.

Everything starts up OK and it starts carving the sign and then I can hear it start to struggle to spin and then it slows down and stops spinning. This happens after a couple minutes. The machine continues to go back and forth as if it is carving, but whatever bit is in is stationary. When I open the lid, I try to spin it by hand to see if anything is catching or binding and it seems to spin freely.

Any tips on how to proceed would be greatly appreciated.
