DIY Geeetech Delta Rostock Mini G2s Dual Extruder 3D Printer Kit With Auto-leveling<br>Note: This is an upgrade version， has changed the plastic printing part to metal， make it more robust and against damage . (This message is update at 2015-10-07)Update information: The linear bearings fixed block has changed from Aluminum to high toughness ABS injection molded parts， solved the problem of not enough fixed， performance is better and motor load is lower. (Update at 2016-01-15)<br>If you need to buy the upgrade kit， please search Product ID: 1012856 <br>Feature:<br>This Rostock mini G2s is the 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 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 probe 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 supports 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.<br>Main features:<br>1. With dual extruder， support multiple way of printing.2. Support PLA， ABS， Nylon and Wood.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.<br>Specification:<br>Print Volume: 170 x 200mmChassis: laser -cut acrylic plateThe Layer Thickness: 0.1mmLayer Resolution: 0.1mmFilament Diameter: 1.75mm， 3mm (Optional) (package is not included)Nozzle Diameter: 0.3mm， 0.35mm， 0.4mm， 0.5mm (Optional)Print Speed:  60 to 120 mm\/secPrint Plate Size: 210 x 3mmPrint Plate (Build Platform): aluminum plate + heatbedXYZ Bearings: Carbon steelStepper Motors: 1.8  step angle with 1\/16 micro-steppingMax Heated Bed Temp: about 110 \u2103Max Extruder Temp: about 240 \u2103AC Input: 115V\/1.5A   230V\/0.75AOutput: DC12V\/0-15AExtruder: 2Connectivity (Interface): USB， SD CardControl board: GT25603D printing Software: Repetier HostCAD Input data file format supported: STL， G codeClient Operating System: Windows， Linux， MacMachine Dimensions: 320 x 320 x 870mmMachine weight: 9kg<br>Download Document:<br>CE-EMC Certificate.jpgCE-LVD Certificate.jpgFCC Certificate.jpgROHS Certificate.jpgRKM
