As figure
Ⅳ.Firmware Upgrade Instructions
The factory firmware is up to date, so no need to update.
1 The ways to get the MKS TFT28/32 Latest Firmware.
Get firmware from customer service or technician
Download the firmware from the makerbase discussion group.
Download on Web:
https://github.com/makerbase-mks?tab=repositories
2 The methods for updating the firmware
4.2.1 Copy the latest upgrade to the SD card root directory, including:
Mks_font
Mks_pic
Mks_config.txt
Mks_tft28.bin
Mks_WiFI.bin
Attention:Do not modify file names.
No need to copy mkswifi.bin without WiFi module.
2.2 Plug the SD card into the motherboard and power on,hear drops ~ ~ A short sound, touch screen
display update process, and so about 30S after the completion of the update.
2.3 You can click”Settings--about”on the touch screen , to view current firmware information.
2.4 Advice: After the update is complete, delete the pictures and Fonts folder, avoid the next time to
update the pictures and fonts.
ATTENTION:If you use ramps1.4, you must upgrade the external 12v power supply, and the MKS series does
not need an external 12v power supply.

3. Base settings（Important, must be set）
After getting the configuration file from the technician, you need to configure the printer type settings.
Attention：1.The baud rate in the configuration file must be the same as the motherboard baud rate, so that
you can communicate.
2.Because the touch screen is the use of serial communication, to avoid conflicts with the
USB .When connecting to the touchscreen, it is best not to connect the USB port on the
motherboard.Similarly, when burning the firmware to the motherboard, it is best to unplug the touchscreen
connector.
4 Multiple language Settings
Currently, languages can support 5 national languages, 1: Simplified Chinese, 2: Traditional Chinese, 3:
English; 4: Russian; 5: Spanish
Enable the difference between multiple languages:
1. Do not enable multi-language language: Use with the previous text, the text is in the picture, the
displayed language can only be displayed by brushing the picture.
2. Enable multi-language: You can slice the language freely in the language options in the settings, currently
supports up to 5 languages.
#multi-language(enable:1, disable:0)
>cfg_multiple_language:1
# Language (1: Simplified Chinese; 2: Traditional Chinese; 3: English; 4: Russian; 5: Spanish )

#This configuration is valid only when cfg_multiple_language is set to 1.
5 Automatic Leveling and Manual leveling
1 . Equipped with a leveling device can be selected in the configuration file automatic leveling (the position
of the arrow is configured to 1), in the Touch screen settings interface can be adjusted leveling.Attention:For
motherboards using the smoothie firmware, select the command to send as G32, as shown below:
2 . Manual leveling can be used on the general model structure (MB, I3, etc.), set in the configuration file
needs to be in the hot bed leveling the three point leveling, four point leveling or five point leveling, the
following figure:
6 Filament Change Function
Filament Change Function, so that you more convenient to replace the supplies, you can also pause in the
printing point after the use of the feed function. The extrusion head rotation speed and minimum
temperature can be configured in the configuration file, as shown in the following figure:

7 Breakpoints recovery
When you spend most of your time printing a model, the careless error operation causes the print to
stop, but does not want to waste the printed model. Then you can use the breakpoint to continue to play the
function, save your beloved model. The following illustration requires that you follow these steps:
1. First click “Preheat”, the extrusion head and hot bed target temperature set (no hot bed can ignore the
hot bed target temperature).as Figure 1
2. When the temperature reaches the target temperature, click “homing”, choose to homing, so that the
axes are back to home point.(Attention:Model printing failure to select Breakpoints recovery the
operation between the Midway, if there is a power outage must be homing operation, such as
continuous electricity can not return to home point operation).as Figure 2
3. After the axis back to home points, move the z axis will touch the mouth to stop printing of the layer,
such as Figure 3, Figure 4, the time to test eyesight (can be selected in the configuration file to allow error,
the following figure
4. Point setting, click on the breakpoint recovery and select the file to be printed on the breakpoint
recovery, as shown in Figure 5, figure 6.
5. After you select the file, wait for it to print.as Figure 7.
(After selecting the model, the larger the model, the more complex it is, the longer it waits here.)
The steps of breakpoints recovery:

8 Save the gcode data with power off
In the printing process into a paused state,when without anyone watching you can directly shut down, the
next time you can start from the pause to continue printing.
(Attention:Remember to delete the updated file in the SD card, to avoid the reboot and update the firmware,
affect this feature).
9 Power off recovery
1. No UPS Power
1.1 A sudden power outage during the printing process, machine can continue to print from the power off.
(due to power failure can not drive the motor, the print head will still remain on the model, may cause
defects in the model, if the need for more complete power off processing, the need for power detection
module and UPS).
Have UPS power
2.1 Power detecting module signal line s connection PB0, negative positive connection -and + two pins
blow the PBO.
2.2 When the system loses power, the Power detection module informs the touch screen to enter the
suspend printing state, UPS power supply. Leave the print head out of the model.

10 Filament detecting
The end of the break detection switch is connected to the PB1, the other end is connected to the PB1 under
the ”-”pin, can be in the configuration file to select a high level of effective or low level effective, the
following figure

11 Auto off after print finish function
Open the auto off after print finish function in the configuration file, cooperate with PWC to complete the
shutdown module, you can use the shutdown function after playing.
Attention：Do not reverse the N and L lines

Ⅴ.The network printing function
MKS TFT28/32 Need to use MKS TFT-WIFI to achieve network printing.
5.1 Introduction to Print Mode
1. Cloud Print Mode: Recommended for use in a WiFi router environment with Internet access. Once you
have a network connection to the WiFi module, the printer becomes the online printer on the cloud.Access
to the app or control printer anywhere in the world. can also be in the local area network through the host
computer (Printrun, etc.) to control the printer.
2. LAN Print Mode: Recommended in the case of a WiFi router, but the router is not available on the Internet
or the network is slow (the cloud Print mode printer responds too slowly).
3 . AP printing mode:When the printer is in an environment where there is no WiFi router, the WiFi module
is not configured, the WiFi module is configured, but the network environment is not good enough to
connect to the router, the above three cases are entered by default.At this time the WiFi module will
produce hot "mkswifi-xxxx" (open hotspot, no password), you can access the hotspot through the app,
browser, host computer (Printrun, etc.) to control the printer.
4 . WebServer print mode: special mode, not recommended. This mode also controls the printer in the LAN.
It can be controlled by the computer's Web, transfer files, print, etc. It can't use the APP control. You need to
brush the Web version firmware to use it.
