Firstly you need to be running sailfish firmware.
My guide can be found here:

If you only want to pause at one location, lets say at 20mm then at the end of your Start GCode (under the scripts tab) you can add the following command line
If you want to pause at multiple location, there is also a way to script this using GPX. At the end of Start GCode (under the scripts tab) you will see a reference to
Code: Select all
M73 P1 ;@body (notify GPX body has started)
Move the body macro to a separate line, and place some pause macros in front of it. For example if you wanted to pause at 3mm and 6mm do the following:
Code: Select all
M73 P1
;@pause 3.0
;@pause 6.0
;@body (notify GPX body has started)
Obviously you will need to remove these additions to slice other objects, but this is the way to do it.
