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.

the X motor assembly is the same for either the Mk2 or Mk2S
