help with extra drivers ramps 1.4

lookin for some help with getting extra drivers working. i used the link on the dual end stop section of v1 engineering to allted/marlin.github the x,y,z drivers are working not the e0,e1. only thing i did before upload was change motherboard in the config h section to ramp 1.4_EFB do i need to do more in marlin code.

issued m119 command and x1 x2 not showing up so i realize i have wrong firmware.
