On the ANET A8, the front and rear places are machined with so huge tolerances that the Y rods are free to float with at least 1/10th mm of play.
This is one cause of X woobling, noise and vibrations.
This very simple thing intends to lock the Y rods in a correct position pushing them downwards which is their nominal place under gravity.
I designed those lockers to make them springy.
Just slide them on the rod (take care there are right and left parts), then pull the bottom and clip it under the frame.
print as delivered
you shall print :
- one Left Front
- one Right Front
- Two Rear
I printed them in PLA, but there are maybe better material for this. I'm afraid the PLA would not keep its dimensions over time
EDIT : I discovered PETG, I think it would be better for this thing. More robust, more springy that PLA !
