I can now use Simplify3D to make a gcode file that Replicatorg and execute on the printer. I can't use the x3g file though -- not enough z axis action...
This suggests that somehow GPX is using the wrong steps/mm for the Z axis. GPX has built in values and for the "Cupcake with Pololu XYZ and MK5/6 extruder with Gen 4 extruder controller", I think it tries to use
static Machine cupcake_P4 = {
{9600, 500, 94.13970462, ENDSTOP_IS_MIN}, // x axis
{9600, 500, 94.13970462, ENDSTOP_IS_MIN}, // y axis
{450, 450, 2560, ENDSTOP_IS_MIN}, // z axis
{7200, 50.235478806907409, 400, 1}, // a extruder
{7200, 50.235478806907409, 400, 0}, // b extruder
1.75, // nominal filament diameter
0.85, // nominal packing density
0.4, // nozzle diameter
1, // extruder count
20, // timeout
3,
};
which suggests the (insane) 2560 steps/mm for the Z axis. But if somehow GPX is being told a different Cupcake config, then GPX would use the wrong conversion from mm to steps thus accounting for seeing a "squashed" Z dimension (too few steps executed for each mm of Z travel). And, being squashed in Z but with correct E values would cause over extrusion -- too much plastic.
