duet wifi not recognizing the first layer

I have Slic3r set to make a 35mm skirt, but I don't do anything else. It's the same think I do for Cura or Simplify3d. Although S3D won't let you set a specific amount just number of walls.

Here is some code from S3D. It does not have those z moves. I think what is causing those z moves is the way slic3r moves the nozzle at home position. It raises it, then lowers it, then moves on the bed. S3D just goes to home and moves the nozzle in a straight shot. But even Cura raises the nozzle and then lowers it as it moves to the location on the bed. the g code flavor I am using for Slic3r is Reprap. Not sure what to say here other than deal with it if I want to use Slic3r. It's only one off. Perhaps it's an issue in Slic3r (sounds like it as other slicers don't have the problem).

Either that's specific to the dev version of slic3r you're using or there is some additional gcode in one of the slic3r windows adding that. Check the various panes of filament settings and printer settings to see if it's adding the gcode somewhere.
I'm unable to reproduce it with either the most recent dev version of slic3r 1.3 or from the latest slic3r Prusa edition.
Have you tried the Prusa edition lately? It's really quite good. The new gcode visualizer preview is very handy.
