Linear rails getting scratches, grooves. Anyone Else?

Hello Everyone,
I am noticing my linear rails are getting grooves and scratches in X and Y. I got my printer in December and lubed it with lubit8. I have recently taken them off and put Super Lube on them but that was after I noticed the scratches. Anyone else noticing scratches. I have been cleaning and lubing the rails about ever time I use it so I am a bit perplexed that they are scratched. The Y are worse than the X.
Thanks
Richard

You may not of seen the posts. Look here for the history on scratched rails. I'll be looking at mine when I get my printer.

you probably got the softer rods mistakenly shipped with early mk3's. contact chat on the prusa website, and they will tell you to email with pictures, soon you will receive the proper rods. the softer rods will not hold a magnet, the hardened ones will.

Just checked my rods with a magnet and it did not stick. I ordered early morning on the third day that the MK3 came out. I have built XYZ stages for 25 years with all kinds of rails/bearings and never seen anything like this. Everyday is a school day. Learn something new every day.

Thanks
