I have to try to turn back on 3.1.1 but it is not simple to turn back from the beta. It doesn't connect anymore

In your video your belts look to be very loose which could lead to skipping on the idler teeth. I think that's your main problem.

Ok, I'll check that. Thanks

I tried to tight the belts but it is the same. When I move the carriage (printer powered off) with my hand, the movements are smooth.

So the belts aren't flopping around loose anymore?

Can you post a video of the motion now?

It seems mechanical in nature. Check your belt paths closely.

When I thight too much, I hear mechanical noises. I have to tight a tensioner more than the other one to have a correct carriage symmetry.

I upgraded to the beta 3 and it seems better.
To be tested

Unfotunately It was a short time success. It still loses steps.
I turned back to 3.1.1 and this time erverything disappeared. No lost steps anymore.

Thanks. I've moved to beta firmware forum for @chrishamm to see.

Try to install this experimental firmware build by uploading it on the Files -> System page and then confirm the update prompt. That should get you to RepRapFirmware 3.2-beta3+3-ch (check on the Settings -> Machine page).

Please let me know if that resolves your problem.
