Does anyone have ender 6 experience?

Printer Model: ender 6

Just curious if anyone has or had an ender 6?
I currently have one and just recent it suddenly has this annoying rattle on movements and a grind almost along the x axis while doing and x movement…i do have a linear rail on the x axis and have checked for dirt etc re greased and re assembled the x axis, still has the same grind sound. I have also played with belt tension and have also notice when motors go to move its almost like they stick.
Now i know this is a klipper forum but i dont trust people on reddit etc, and here there seems to be a very wide variety of experienced people.

So pleaseif you may have a pointer, i have run out of ideas and would really like to get this thing back in service.

Thank you!
