Squeking noize at some lokations when printer do faster z-travel

Hi,

For a couple of weeks the printer makes a squeaking noize when "faster" z-direction travel. Especially at points where it often stopts. like when heating or when finished.

Any suggestions?

If the answer is to lube, what lube should I use where? I have both. What is the linear rail that should not be lubed by the Prusa Lubracant? I can't find it in the manual.

Prusa Lubricant: a tube of Prusa Lubricant is included with the Prusa CORE One. It is used to lubricate the smooth rods with linear bearings, and to lubricate the Z-axis leadscrews. DO NOT use Prusa Lubricant on the linear rail!

Linear rail lubrication set: a set that includes Microlube GL 261, Dosing needle SSS15 2, Cartridge with manual piston 2/2,5mm, and two nitrile gloves.

- from own experience with squecking sounds/noises I recommend to look at the hinge of the swingarm for cable/PTFE tube (you have to remove the top cover); print something and when you hear it - mostly it is when the printhead is moving a specific direction - push the swingarm a little bit up; in case the squecking stops -> stop the print, remove build plate, cover the bottom of the print, put a little WD40 at the hinge (spray softly or even better use a brush) -> it should stop making squecking sounds/noises

- for maintenance of the linear rails look at the linear rails lubrication guide for the XL with link to the lubrication set

- the Prusa lubricant which comes with the printer is ONLY "used to lubricate the smooth rods with linear bearings, and to lubricate the Z-axis leadscrews. DO NOT use Prusa Lubricant on the linear rail!" ( https://help.prusa3d.com/article/regular-printer-maintenance-core-one_829710?product=core-one-plus)
