Geeetech

Open Repetier-Host (Download link: http://www.repetier.com/download-now/), Access "Printer settings": Set amount of extruder as 2, and set correct nozzle diameter: Then you can control both extruders on Repetier-Host (Note:The extruder can not move unless the temperature is more than 180 degrees): Slicer setting:
To have a good 3D item,you need to have a good slicer setting, and distribute jobs for 2 extruders:
Click "configuration" to access slicer setting: For more details of sclicer setting, you can download the attachment to refer:

the software show is not even close to the current version available for the mac...can you up date your instructions for the current version.

I'm also having trouble getting it up and running using a Mac. Instructions are unclear, and the programs look different on Mac.

Hello, I am in possession of a geeetech 3i. Small problem during the execution of gcode with slice3r, fusion son are not contiguous. We can help by m m addressing the right configuration of the printer with a 1.75 thread.
Thank you very much

For two-color printing it is possible that I have to change here?

// Offset of the extruders (uncomment if using more than one and relying on firmware to position when changing).
// The offset has to be X=0, Y=0 for the extruder 0 hotend (default extruder).
// For the other hotends it is their distance from the extruder 0 hotend.
#define EXTRUDER_OFFSET_X {0.0, 0.00} // (in mm) for each extruder, offset of the hotend on the X axis
#define EXTRUDER_OFFSET_Y {0.0, 0.00} // (in mm) for each extruder, offset of the hotend on the Y axis

Keep up the great work thank you for posting
