Good morning,

I noticed issues with the skr mini e3 v3 purchased one week ago, on the last 3 prints.

For the first 50-60% print status all is ok, then the Y-axis is starting to slide backward. The slide is happening on few Z steps and after that the print is continuing normally. The piece is well attached on the bed and no physical impediment occured with the moviment of the Y axis. The gears, wheels and all related are well tightened.

This never happened with the origonal maimboard so what I think is that there is some fault with the Y driver.

Could you please support me in finding out this issue and tell me what I have to do?

Thanks for your kind attention

Adri
