Error: Loose Pulley Motor

Hi there guys,

Firstly I have an i3 MK2.  I don't know if its a MK2S or not.

I am running the wizard calibration and it keeps stopping and saying "Loose Pulley Motor.   The X Axis belt seems taunt enough, but I am not sure.  

Any help would be appreciated.  Thanks everyone!

Hi , i had simliar on mk3s

Slacken off belt tension and slacken off belt pulley screws. Do the 2nd screw first , then the flattened surface one . Retighten the reverse way. Check belt and pulley alinement across the uprights and for the belt running true.

Retension belt , needs to twang abit like a guitar string , if the belts touch they are likely to still be to loose , so shorten slightly.

I will try that but I am not sure which is the "second" screw.
