I am setting up a extruder\_stepper as below but was unable to asigned it to the tmc2208. did i do a wrong syntax or the extruder\_stepper does not have a specific setting.

Hello @tphan !

Can you please put your code snippets into code braces **\</\>**?  
You find them in the top bar of the edit window.

Without them, spaces and other letters get lost and its difficult to find out what is maybe wrong Thank you very much.

Replace `[tmc2208 share_stepper]` with `[tmc2208 extruder_stepper share_stepper]`
