Unload script works via Repetier Host but not via SD card

I tried putting simple filament loading scripts for my bondtech extruder on to my sd card:
G92 E0 
G1 E300 F2000
G92 E0 


I tried cold extrusion M302, relative mode M83 nothing works when printed from SD card,
but works fine when send from Repetier Host.

Why is this?

  • I'm using dev 1.0.0
  • Where did you add that? What I mean is are the commands written to sd card or are they in hosts end script which is not part of sliced gcode and gets send by host when host print is finished. These scripts are not executed when you run a sd print.
  • They are written to SD card like a usual .gcode file.
  • Try
    G92 E0 
    G1 E50 F2000
    G92 E0 
    G1 E50 F2000
    G92 E0 
    G1 E50 F2000
    G92 E0 
    G1 E50 F2000
    G92 E0 
    G1 E50 F2000
    G92 E0 
    G1 E50 F2000
    G92 E0

    firmware blocks long extrusions to prevent problems, maybe you hit that limit.
  • Problem was my fault, I set the virtual extruder ratio to 0. 
    Thanks for your fast help anyway, as always.
