1Delta Rostock mini G2s.jpg

This Rostock mini G2s is a companion piece of our new upgraded delta 3D printer -Rostock mini G2. G2s is designed to support dual extruder. With G2s you can print a single two-color object, or you can print two objects in one print job, each made from a different color. You can also print one single-color object, as with other single-extruder 3D printers. Or you can use one extruder for infill or support. The 2 extruder motor pushes filament through 2 head separately, so mixing colors printing is not applicable for the moment. This G2s is powered by our newly designed control system—GT2560 that supports 2 extruders and eliminates the complicated wiring of Mega2560+Ramps 1.4 and it is more space-saving. An auto-leveling auto-calibration device is also added on G2; which means you do not have to adjust it every time before you start printing, after the first assembly work, you can almost plug and play. In terms of printing filament, G2s not only support PLA and ABS, Nylon and wood filament is also available, which enables more possibilities to create 3D printing project. This G2s is also improved with LCD control panel; you can monitor the printing process in real time and with a SD card it can realize stand-alone printing, very convenient.

Main features:

1. With dual extruder, support multiple way of printing.

2. Support PLA, ABS, Nylon and Wood, giving more possibilities to create 3D printing project.

3. New updated control system.

4. Auto-leveling and auto-calibration.

5. More flexible effectors and diagonal rods.

6. More fluent printing process and higher precession.

Building Modifications

The following are community provided modifications to the Geeetech Delta Rostock G2/G2S, and are not provided by nor approved by Geeetech. Use at your own risk.

Z-Probe Lock Ring

If you have problems with the Z-Probe lock ring slipping, or are worried that your will strip the plastic threads in the lock ring while tightening the jam bolt, simply file a flat into the Z-Probe at the location where the lock ring will be.

Then, the lock ring will be unable to slip.

G2S J-Head Orientation

The G2S build documentation leaves the orientation of the J-Head up to the user. Many different orientations are possible.
