Connect the TFT display to the Aux-1 of MKS series controller board. The TFT display is not necessary to connect external
12V power supply.
IV. Function Instruction
1. The way to get the latest firmware
1.1. Ask the customer services for the latest firmware.
1.2. Login this website to download: https://github.com/makerbase-mks/MKS-TFT
2. The ways to upgrate the TFT firmware
2.1. Copy the latest program to the the root directory of the SD card, including:
Notice: Do not change the file name.
2.2. Plug the SD card, power up again. The screen will show the upgrating progress when hearing a short sound “didi~”, then
the upgrating is finish after about 30 seconds.
2.3. View the current firmware version through clicking “Set>About”.
2.4. Suggest deleting the picture file to avoid uograting the picture again when booting next time.
Notice: when using Ramps 1.4, you must connect external 12V power supply to the TFT display before upgrating the firmware.
3. Boot Settings
It’s necessary to set the printer type when getting the configuration.

Notice:
3.1. For communicaion, the baud rate of the TFT display must be same as the controller board.
3.2. To avoid the conflict with the USB interface, it is not advisable to connect the USB and TFT display at the same time.
3.3. Click “set>File Sys>U disk” when using U disk, only on this way can the TFT display show U disk file.
4. Multiple language Settings
Support 5 different languages :
1: Chinese
2:Traditional Chinese
3:English
4:Russian
5:Spanish
It’s available to set whether enable multiple language.
4.1.Disable multiple language: the use is the same as before. The words are on the pictures, so the shown language is achieved
by flashing the pictures.
4.2.Enable multiple language: It’s available to set whether enable multiple language.
5. Automatic Leveling and Manual Leveling
5.1. It’s available to choose auto leveling function if the printers are equipped with the leveling device. You just need to click
“set>Leveling” on the UI interface.
Notice: If you use the controller board running smoothieware firmware, you should choose G32 on config.
5.2. Manual leveling can be used to the common printers, such as MB and I3. You just need to set the three points, four points or
five points that are needed to level on the heated bed in the TFT config.As shown below,
6. Filament Replacing Function
Filament replacement function helps easily replace the filament, moreover, users can replace the filament by clicking “Pause”
#multi-language(enable:1, disable:0)
>cfg_multiple_language:1
#languages setting (simplified Chinese:1; traditional Chinese:2; English:3; Russian:4; Spanish:5). This
configuration is valid when "cfg_multiple_language" is disabled.
>cfg_language_type:1

during the printing. Users can set the extruder unload speed and min temperature of “filament replacement process” on the config.
7. Print from the Breakpoint Function
Undoubtedly, you must feel crazywhen you mistake the operation to stop the printing. Take it easy, the printing from the breakpoint
function would help you save your beloved model . The operations are as followed,
7.1. Click “pre-heat , set the target temperature of the extruder and heated bed . (picture1, picture2)
(No heated bed, you can ignore the target temperature of the heated bed. )
7.2. Click “Home” when the temperature reaches to the target temperature, let every axis go back to the zero point. (picture 3)
7.3. After every axis goes back to the zero point, move the nozzle to the layer where stops printing. (picture4, picture5) As shown
below,
7.4. Click “Set”, then click the printing from the breakpoint, choose the file that print from the breakpoint.( picture6, picture7)
7.5. After choosing the file, just wait to print. (picture8) (After choosing the file, the larger and more complicated the model is,
the longer time you need to wait.)
8. Power Outage to Save
The printer is allowed to directly turn off if it suddenly enters the pause state while printing. The printing will be continued from the
pause when restarting next time.( Remember to delete the upgrated file from the SD card to avoid upgrating firmware again when
booting next time, otherwise, it can’t print from the power outage point.)
9. Power Outage to Continue(only above MKS TFT28 V1.1 can support this function)
9.1. Don’t connect UPS power supply
The printer will continue printing from the pause when restarting, if it suddenly powers out.( The motor can not be driven due to
#the speed to extrude filament(mm/min)
>cfg_filament_load_speed:1200
#the lenght to extrude filament (mm)
>cfg_filament_load_length:200
#the speed to retract filament(mm/min)
>cfg_filament_unload_speed:1200
#the lenght to retract filament(mm)
>cfg_filament_unload_length:200
#It is the minimum temperature for filament change.It will auto heat up if the current temp doesn't
reach the target.
>cfg_filament_limit_temperature:200

power failure, so the extruder still stay on the model, which may cause defects on the model. If you need a more complete way
to deal with such situation, a power outage detection module and UPS is necessary).
9.2. Connect UPS
9.2.1 S connects to PB0, negative and positive connects “-“ and “+” of PB0 .
9.2.2 Power outage detection module will inform the TFT display to enter the printing pause state when the system powers out,
then the UPS will provide the power for the extruder to leave the model.
10. Filament Outage Detection function(only above MKS TFT28 V1.1 can support the function)
One end of MKS DET connects to the PB1, another end connects to the “-“ or “+” of the PB1.( If Low Level effective, it connects
to “-“, if High Level effective, it connects “+”.) Choose the Low Level effective or High Level effective in the configuration.
