Does my Nomad 3 sound normal?

[Gerry]

Yeah… perhaps there’s a sizing or tolerance issue on some of the bearings?

I have some mild grooves on my horizontal bars from the bearings (my machine is two years old though), but this fellow has pits on his Nomad 3 that look quite different - harsh even - even after replacing the whole machine:

Grooves in x-axis guide rails

Hi Will, Mostly cutting acrylic. No dust collection the machine is standard with no mods. I have been lubricating the rails with Super-Lube with PTFE about every week (~45) machine hours. Here is a photo of one of the grooves, all are about the same size and run parallel to the direction of motion. [20220201_115705]
