Step twenty-six: firmware
The firmware used on the MKS BASE controller is Marlin. This is an open source project, and MKS is the right version available on the page. New versions are posted on this page periodically, and the package described here will be the same as the “firmware (marlin & TFT) .zip”, which contains the Marlin firmware version 1.1.6 and the firmware for the TFT32 touch panel. Select this option and click the Download button. The following instructions assume that you are using a PC running Windows 10 to process packages, but equivalent operations are available on a Mac.
Create an empty directory to store the firmware. Unzip the zip file, then unzip the Marlin package inside it.
Download and install IDE Arduino from . Launch the IDE and use File> Open to select the Configuration.h file from the Marlin package directory. Now make sure that the package can be compiled by clicking the "Check" button. After several minutes of processing, a message about successful compilation should appear at the bottom of the screen.
Select the tab containing the Configuration.h file. Check and edit the text:
#define TEMP_SENSOR_BED 1
#define DEFAULT_Kp 20.64
#define DEFAULT_Ki 1.58
#define DEFAULT_Kd 67.31
#define X_MIN_ENDSTOP_INVERTING true
#define Y_MIN_ENDSTOP_INVERTING true
#define Z_MIN_ENDSTOP_INVERTING true
#define INVERT_X_DIR true
#define INVERT_Y_DIR false
#define INVERT_Z_DIR true
#define INVERT_E0_DIR true
#define X_BED_SIZE 200
#define Y_BED_SIZE 200
#define Z_MAX_POS 185
#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,4000,400}
#define DEFAULT_MAX_FEEDRATE {500, 500, 3, 25}Without turning on the printer, use a suitable USB cable to connect the PC to the MKS BASE controller. Select the Tools menu in the Arduino IDE and verify that the board and processor are displayed as shown in one of the images. The port should show the USB port that is used to connect to the controller. Now click the “Download” button.
Step twenty-seven: testing the controller
Download and install the Pronrface Printrun package at:.
Before starting the test, manually move the print unit and print head to the center. Use a ruler for proper positioning.
In the lower right corner of the window, enter “M119” and click on the “Submit” button. One by one, press and hold each of the X, Y, and Z axis switches. Press Submit after each press of the switch. Each test should show the corresponding switch as TRIGGERED.
Connect the 12 V DC power supply to the printer and turn it on. Move the print head up 1 mm by clicking the “1” button inside, which is located in the Z movement section of the screen. Make sure that both Z motors move in unison and the print head rises 1 mm. You can press the button several times to confirm.
Repeat the same test with the X and Y engines using their on-screen controls. The print head should move to the right, and the printed circuit board should move toward the front of the printer.
Manually adjust nodes with limit switches.
Press the X home button and make sure the X carriage moves to the left end and stops. Perform a similar test using the Y home and Z home buttons.
In the window section with the inscription "Heat" enter 210 ° С. In the lower left window after T, the current nozzle temperature is indicated. Click Set. The nozzle should start to heat up, and the chart to the right of the button will show that the nozzle temperature is rising.
