Grooves in x-axis guide rails

[AndrewR (Andrew Rassenti)]

Hi I have been using the nomad for over a year now. I noticed one day on inspection that small grooves had developed in the x-axis guide rail, so I sent the machine back and was sent a new one. Now about six months into using the new machine I have noticed the same grooves appearing in the x-axis rails again. Has anyone else experienced this problem?

What material are you cutting?

Are you using dust collection?

Have you been lubricating per:

What do I use to Lubricate the Rails?

Could you please send photos of the grooves in to support@carbide3d.com?

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.

Deeper grooves on Y rod

I will contact Carbide 3d support. What will be the consequence of this wear on the linear rod? I assume and fear that I have not done enough maintenance, but what is there to do other than clean? Should the bearings not be sealed and pre packed with grease? Maybe something has gotten onto it… [R0010015-01]

I meant to write X. I have the same issue in the same spot.
