1) MKS-HLKWIFI intruduction：
MKS-HLKWIFI is based on HLK-RM04 module. It can work with MKS Gen , MKS Mini board or MKS TFT28 V1.1 LCD and control 3D printing remotely through wifi. In this tutorial, we only give instruction on how to use MKS-HLKWIFI working with MKS TFT28 V1.1.
2)Parts and Devices in this project
MKS-HLKWIFI module x 1
MKS TFT28 V1.1 LCD x 1
connect MKS-HLKWIFI to MKS TFT28 WIFI socket as per following picture:
4)mks_config.txt Wifi Configure(Only MKS TFT28 V1.1 or higher version supports MKS-HLKWIFI module)
if you purchased MKS TFT28 or MKS TFT3.2 touch Screen，You will have a config file mks_config.txt in the driver. In this file, you will see many configuration information for MKS-HLKWIFI module(see following points):
i)Wifi module selection in section cfg_wifi_mode: set 1 for AP mode and 0 for client mode
Client mode :
If you set cfg_wifi_mode value to 0 (client mode), the MKS-HLKWIFI module works as a client of a wifi hotspot. You should configure following information in order to get it connected to hotspot.
A.Wifi hotspot name setting
in "cfg_wifi_ap_name " section, write the wifi hotspot name.
B.wifi password setting:
In "cfg_wifi_key_code " section, write wifi password of the hotspot you need to connect to.
in "cfg_ip_dhcp_flag" section, set 0 to config static IP, set 1 to configure DHCP IP.
D.Ip address assignment
If you set "cfg_ip_dhcp_flag" to 0 (static IP), you need set the static IP address in "cfg_ip_address" section.
set IP mask in “cfg_ip_mask” section
set gateway in “cfg_ip_gate” section
If you set cfg_wifi_mode value to 1 (AP mode), MKS-HLKWIFI module works as a wifi hotspots, you should config following value in order to allow other device to connect it through wifi
A.wifi hotspot Name
in "cfg_wifi_ap_name" field, set the wifi name of your hotspot.
in “cfg_wifi_key_code” field, set the hotspot password
5)Connect MKS-HLKWIFI module to Wifi network
In section 4), we have talked about 2 working mode for MKS-HLKWIFI module works : client mode and AP mode.
If you set MKS-HLKWIFI module works in client mode, you can do following steps to connect it to Wifi hotspot:
I)save above mks_config.txt in a SD card (or USB storage) and insert it into MKS TFT2.8 LCD. Turn on the power, MKS-HLKWIFI will connect wifi hotspot as per your wifi hotspot/password setting. If it connects to wifi hotspot successfully, LCD screen will show "Connected", otherwise LCD will show "Disconnected"
See following picture:
6)Use Android app to control LCD
download a href="http://osoyoo.com/wp-content/uploads/2016/07/app-for-Android.rar">app for Android to your pc, unzip the file and then load this apk file into your Android cell phone.
In IP address text field, input IP address you get from LCD(see picture 3). Default port number 8080
7) Use Printrun to control 3D printer remotely
Download Windows Printrun from
http://osoyoo.com/drivers/Printrun-Win-Slic3r.zip, unzip and run the exe file.
Note, you should make sure IP address in printrun software same as Ip address showed from LCD (see picture 3)
