Hi illuminarti,
With the power off I can move them "easily" (I don't exactly know was is easy) but they still make this sound.
For sure it's not the end caps since I have a washer between the cap and the case.
But how exactly check if it's twisted, if it is, is so little that I can't see it with my eyes.
Could it be a very small misalignment between the pulleys of the same belt and the belt teeth jumps off the pulley?

I'd start by checking if the belts it sliding blocks are rubbing on something when moving in x. Also look at the bearing I the head assembly - is it sliding smoothly on the cross rod, or is it twisted out of straight so that it skips in short jerks as the friction is overcome and then binds again?
Also check that the motor and short belt are ok, and not catching on anything. The end caps over the the rods need to not be too right, so the rods are free to rotate.
Probably easiest to check it with the power off - sliding the head by pressing both sliding blocks for the x axis with fingers. They should slide easily with fingertip pressure.
