Combining Skeinforge Gcodes

I'm trying to print the double Helix at .1mm, but there are some self intersections in it that cause problems in Slic3r. The first one or two bridges for each crossbar are unconnected at both ends. Kisslicer can't handle it either, but Skeinforge can. Since I am doing .1mm layers, I want plenty of perimeters, fill and solid layers for the base, but not the actual helix. With Slic3r I would slice it twice and copy/paste the gcodes. Whenever I have tried that in Skeinforge, there have been problems with the extrusion. Skeinforge has the ability to define start and stop layers which would be perfect, but if I slice from layer 62 to 9999, layer 62 will be placed on the print bed and not at the proper Z.

Is it possible to join Skeinforge gcodes to change parameters mid-print?

G92 Z0 will reset the current Z height to 0, I think in Skeinforge the first layer is printed at 0 rather than layer height so what you'll actually want is

G92 Z0
G1 Z0.1 // or whatever the layer height is
G92 Z0

You'll need to make sure the second set of Gcode doesn't do anything stupid like Home Axis G28 or reset the coordinate system G92

Would I need to include G92 E0 as well? Or would it be okay to run both gcodes with relative extrusion?

You would need the G92 E0

I believe that the "Bottom" plugin sets the first layer height location. See: http://fabmetheus.crsndoo.com/wiki/index.php/Skeinforge_Bottom
