Hi all,
I have been experiencing a loss of steps in my Z axis which eventually leads to a lowering of the bit over time. I have taken the Z axis apart and cleaned thoroughly and while doing so I I have noticed the rollers and the rail were worn and rough in places. I have been conducting my maintenance every 20-25 hours of running, wiping down and re greasing etc. I have no idea what could have caused the wear or pitting on the rollers or the rail.
After a light sanding to smooth the rails and the rollers I put it all together and it ran smoothly for 7 hours in a 8.5 hour cut then I had the same problem again. I have noticed that I have the same problem on my Y and X rails but i do not have the issue with lost steps.
Has anyone else experienced this wear on their systems rollers or rails? Does anyone know how to reduce/stop it happening?
I have taken the leap to order new rollers and a new Z rail to get back to a known state.
Many thanks,
Sonny

I gave the areas a good clean to remove all the grease and then rubbed over the area with some fine crocus paper to remove any ridges. I also replaced the rollers. Once all was smooth I now lightly grease the area during my cleaning routine. I do not think the scoring is having any detrimental effect on the running of my machine its just a bit unsightly.

... rubbed over the area with some fine crocus paper to remove any ridges....
But be careful, do not remove the coating from the rail!
