Feature:1. With all-metal plate structure, all parts and components have good stability and durability.2. Use TMC2208 (256 subdivision) silent driver to achieve lownoise printing without affecting other work.3. Equipped with 3.5in color touch screen, supports multilanguage interface, and is more practical.4. With filament exhaustion detection and power recovery printing function, saving operation time and reducing printing errors.5. The 3D printer supports X/Y, Z axes can be precisely adjusted, accurate positioning, improve printing efficiency.Specification:Item Type: 3D Printer DIY KitMaterial: Sheet metalNumber of Nozzles: 1Nozzle Diameter: Approx. 0.4mmPrinting Accuracy: 0.1-0.2mmLayer Thickness: Approx. 0.1-0.4mmPrinting Method: SD card/online printingDisplay: 3.5in color touch screenMachine Speed: 10-300 mm/sPrinting Speed: 20-200mm/sExtrusion Head Temperature: Up to 260Hot Bed Maximum Temperature: Up to 100Printing Platform: Aluminum substrate hot bed (plus PEI magnetic steel film)XY Axes Positioning Accuracy: 0.01mmZ Axes Positioning Accuracy: 0.004mmRecommended Printing Materials: PLA, ABS, PETG, wood woolConsumption Diameter: Approx. 1.75mmOperating Languages: Chinese, English, French, Spanish, German, Korean, RussianSoftware Format: STL, OBJ, JPGPrint File Format: GcodePrinting Method: SD card/online printingMachine Size: Approx. 410 x 400 x 520mm / 16.1 x 15.7 x 20.5inMachine Weight: Approx. 7.5 kg / 16.5lbSupport Software: For Repetier-Host/CuraOperating System: For Windows/OS XWorking Environment Temperature: 5-40Humidity: 20-60%.Package List:1 x Top Beam1 x Bottom Chassis1 x Left Frame1 x Right Frame1 x X-Axes Frame1 x Right Pulley Bracket1 x T8 Screw Rod2 x Consumable Material Rack1 x Power Cord1 x USB Cable1 x 10 Meters Consumable1 x PC Film1 x Synchronous Belt1 Pack Limit Switch (3 x Screw, 1 x Nut)1 x Screw Package (14 x Short Screw, 4 x Long Screw, 4 x Nut)1 x Tool Bag (20 x Cable Tie, 1 x Screwdriver, 5 x Hex Wrench, 1 x Wrench, 1 x Pliers, 1 x Card Reader, 1 x Memory Card, 1 x Nozzle, 1 x PTFE Tube)1 x English User ManualNote:Drive Current Algorithm and Adjustment: 1. Vref measures the intermediate voltage between Gnd and the potentiometer. Rotate the potentiometer clockwise to decrease the current and counterclockwise to increase the current.2. Make sure not to connect the motor when measuring the voltage, otherwise the driver will be easily burned3. Please turn on the power when measuring the voltage, don't just connect the USB power4. Please pay special attention to the direction, please insert the reverse side hastily
