Hi Everyone,
I have an nm-135. It is about 2 years old, and a couple months ago I noticed some slight roughness when the x axis was moved from side to side. I noticed a rythmic rough sound whose frequency increased as the rapid speed increased. If I placed my fingers on the bed while it was moving I could also feel a slight roughness. I was not worried as it was very slight and did not appear to affect precision or finish. However, today, I started hearing clicking noises on the same axis. I checked the coupler to the motor and that seems tight. So, I am thinking that the axis bearings might be going. Does this sound correct?
Has anyone experienced this before? It is a managable fix? Any suggestions on how to go about getting replacement parts? Previous posts on this forum suggest that going through Novakon may not be the most efficient.
Thanks,
Scott
