Increasingly flaer and flatter long object

[Zoltan3D]

Hello,

I finally achieved the problems with the belt adhesion,

I decided to print a chain of 5 meters for fun, but after 2 meters I stopped printing because I noticed that the links became more and more "flat" (see photos)

this is a chain for fun, it does not matter, but I plan to print long functional objects and it will be annoying in terms of dimensions if the object is more and more "flat"

The general dimension of each link is the same, it is only the face on the carpet which is found lower and lower, however I do not have the impression that the head rubbed more on the treadmill than at the beginning, I don't see any scratches or abnormal noises

Does anyone have any idea where this problem could come from and how to fix it?

Thanks in advance

Ps: is it an impression or the iFactory forum is very very little used?

I found the problem ...

The X/ Y steppers are not powerfull enought, I just have to touch the belt in print, and stepper skip steps easily,
The stepper current looks too low ...
But it give me an other problem :
I opened the electronic box, and discovered than there was no stepper drivers at all inside, so I can't measure and adjust the current

How can I set this ?
Can we set them in marlin with the console ?
