you have noticed that the guide wheels of the printhead carriage are fixed by nylon struts, the lower one is resting on an oblong hole and the Chinese do not seem to be aware that There are washers! mine was already strongly marked after 2 months of use, so I put a washer and I realized that, the nylon crashing, the wheels were loose, the cart had already many games on his rail !
and to tighten them ... galère .. it takes a hand to pinch the rollers on the rail, a hand for the key awl and a hand for the key of 8 to prevent the nut from turning ... hence this small tool to press the wheels on the rail, pressure that you can modulate using a more or less beefy elastic ....................... if the head of cr 10 is the same as anet e10 it will work too !!
