> Description of problem:  Second extruder motor gain is down in the gcode produced by slic3r 1.0.1.  slic3r 1.1.7 loaded from a tarball could print the same .amf piece well, the secodn extruder motor gain was fine.

When comparing the gcode files between slic3r 1.0.1 and 1.1.7 there is less
information for the second extruder in the 1.0.1 version (attached).

The print is stringy from the second extruder and it turns but a a very reduced
rate. This si not a hardware or settign issue in slic3r. For whatever reason
the secodn extruder motor gain appears turned down. The feed-rate values appear
to be correct but it is difficult to tell.

The second extruder x,y locaiotn are fine; elevations are fine; temperautre is
fine. Teh printer host (RepetierHost 0.95) extruders correctly when used
manually (10mm = 10mm)

slicer 1.0.1 (Fedora 20 stable)

compare with 

slic3r 1.1.7 (Tarball, Fedora 21- under testing)

> 1. build .gcode file from .amf (used TWO_COLOR.amf availabel throguh Printrbot) (I can email this to you)
> 2. Print on Reprap/Marlin Printer (Printrbot Go V2)
> 3.wait. 
4. Build .gcode from the same .amf with slic3r 1.1.7 and watch the extruder
perform well.

> Actual results:
> Low 2nd extruder motor gain (low extruder values)

> Expected results:
> Extruder 2 works just the same as extruder 1.

Glad to help any way I can. Living in Calgary, can test code at night.
