Lubricating the linear rails .... but How ...
Hi There ... I am currently performing the secon "large maintenance" on my XL 5T.
And I have trouble to lubricate my linear rails. I am aware of the guide:
https://help.prusa3d.com/guide/how-to-lubricate-linear-bearing-rails-xl_384273
I have the suggested grease / lubricant, I have a propper syringe with flat injection needle and large diameter ... But I am not able to get anything into the holes on the slides of the linear rail. As son as I try to bring in the lubricant it just spills out the hole to the sides of the needle ... already at 0,01ml roundabout ... so basically I just can fill the hole, but nothing goes into the bearing itself. It's the same with all sides of all rails.
During the first maintenance I just thought there still might be enough in the slides, but now I have several couples of hundred print hours ... and still the same. The rail also is starting to get dry. I don't want to damage them since the rails are not exactly cheap.
Did anybody have similar issues or is there a "trick" that can't be seen in the guide. I gently tried to press the needle in deeper, but didn't put too much force to avoid damage.
Anybody already successfully lubricated the rails?
Thanks for any ideas and help.
