MKS-BASE V1.4 all-in-one controller
1. Please make sure that the positive and negative pole is connected in the right position. If they are reversed, the board might be burned.
2. Do not insert or pull out the motor and driver under the live wire. It may cause the board burned. And do not adjust the current during the motor working. The right way to do is to cut off the power supply, pull out the motor, insert the power, adjust the potentiometer, measure the voltage on potentiometer till the voltage is same as expected voltage. Do not reversely insert the driver or it will burned the driver even burn the mainboard.
3. MKS-BASE controller is specially developed controller to against faultiness of RAMPS1.4 and Megatronics V2.0 controller.
4. Can be connected to LCD2004 or LCD12864(no L board). Due to the LCD2004 and LCD12864 open source design standard EXP1 and EXP2 PIN port only, and no standard of cornoid. Some non-Makerbase manufacture LCD2004 and LCD12864 display USB interface direction may not be the same. It needs to connect conversely.
1. It gathers all functions in one board. It’s like a simplize RAMPS1.4+MEGA2560 board. Less breakdown.
2. Use A4982 stepper driver, similar function of A4988 stepper driver. But use SOP potting. Cooling function is better.
3. High quality 4 layer PCB board with heat dissipation treatment.
4. High quality MOSFET tube. Good cooling function.
5. Special power supply chip, support 12V-24V input. No chip heating problem.
6. When connect 24V input, the heatedbed current can be down to 1/4 at the same power system. It’s effectively solve the heating problem of MOS tube.
7. Firmware can use open source firmware Marlin, setting is same as RAMPS1.4.
8. Can connect RAMPS1.4, 2004 LCD or 12864 LCD display
MKS-BASE V1.4 controller interface:
LCD display connecting:
A4982 current testing method: MKS BASE V1.0 controller use A4982 stepper driver as well. It’s compatible to A4988. Load current adjust method are the same.
Max. load current calculation formula is I=V_REF/(8×RS)，RS=0.1，V_REF
Measure method as below picture:
