My Anet have loosy Axis X Belt so this is cure.
In my Anet I turn on lathe reel in aluminium and broke dril 2mm diameter to use as axis.
You can print reel as well.
It works fine for me but if you have any sugestions please feel free to comment.
my print resolution is 0.3 mm layer high. I also use thicker first layer (0.4 mm).
Filament PET G
My first attempt was tensioner which was stick on the top of right Z carrige.
I thik about tensioner which will tension without changing belt dimension...
There is small place to do this and upgrade will conect with open Z right carrige...maybe form motor X axis side would be better to tension?
So for now it is second attempt stick to X axs 8mm rails
