Easier assembly, Mini size and matched Acrylic shell as a gift. What’s more, it supports both DC interface and terminal block for power supply. You can use DC power supply without using heated bed, it’s simple and beautiful.\u003cbr\u003e \u003cbr\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eThe update compared to Micromake 1.3:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003eEnhanced power supply circuit, adopted professional power management chip, support 40V input wide voltage at most while the previous 1.3 version only support 12V.\u003cbr\u003eIntegrated driver chipis updated from 16, 32 microstep2 stepper modes to 16, 32, 64, 128 microstep4 stepper modes.\u003cbr\u003eIt has both DC interfaceand terminal block for your choice of power supply mode according to the situation while the previous 1.3 version can only choose one from two.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003eThe drive chip can support 128 microstep at most and can be adjusted by MS1, MS2 jumper on the control board. H means short circuit, and L means disconnecting.\u003cbr\u003eIf you need to adjust current, please put the positive electrodes of multimeter into screw hole on adjustable resistor and put negative electrodes on USB shell after restarting printer.\u003cbr\u003eThe measured voltage divided by 0.8 equals current of drive chip. Eg: If the default voltage is 0.6V, the current is 0.6\/0.8=0.75A.\u003cbr\u003ePlease be sure to cut off power first, then rotate adjustable resistor with screwdriver. Turn left to decrease the value, turn right to increase the value. Don’t screw too much at one time, 30°is OK.\u003cbr\u003eTurn on the power after adjustment, then measure the voltage, if it isn’t appropriate, please cut off the power and adjust again. Emphasize again, be sure to cut off power before screw the adjustable resistor.\u003cbr\u003eIt’s not recommended to adjust current without multimeter. We have set the recommended value at the factory. It’s 0.75A for XYZ motors, 1A for E motor.\u003cbr\u003eIt’s wrong to say the bigger current, the better. High current will cause hot motor. If XYZ motors are too hot, they will fall out step. If E motor is too hot, the filament will become too soft to squeeze out.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003ePackage includes:\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e1 x 3D Printer Control Board\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"\" src=\"http:\/\/img.banggood.com\/images\/oaupload\/banggood\/images\/E6\/32\/577d4293-b702-438e-b6ac-d7c7f9517c0d.jpg\" style=\"\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size:14px;\"\u003e\u003cspan style=\"font-size:14px;\"\u003eIn the pin definition diagram, GND means negative electrodes, VCC means +5V, VIN means input voltage.
