X-Axis Squealing! (2 replies)

Hello all, new to the forum, but have one of the limited edition RS red ormerod's. Its been printing fine, but yesterday, it seems to have developed an intense and irritating squealing. doesn't seem to have an impact on the printing, but really, it sounds like metal on metal, and it is definitely within the X-Axis carriage or on the track somewhere. I'm not sure if there is anything I can do, or if anyone else has had the same issue and had a fix. It doesn't seem to be directionally related, and it seems to be intermittent and frequent.

Any help would be great!

Thanks very much.
