The firmware has different pinout because we use embedded ESP32 and not dev module, screen is a 4 inch, we add serial USB, battery and charger to become a wireless pendant 'mstrens use it connected to the controler board and power it from the main board.
We also add OTA function
i’m curious, does this run gcode programs from the SD card on the LCD, or is it just a serial interface (allowing remote access to the resources of the GRBL board)? i ask because i use ESP3D on an ESP32 dev board now (seems very similar), but it will only allow you to upload and run programs from the SD card that is built into the GRBL board. i was under the understanding this was because the ESP32 does not allow for multitasking, and running a screen/web interface and trying to drip feed the CNC board could cause the tool to pause while it waits for the next instruction.
i do love the wii mote jack for joystick control, that is a nice touch.
This can do both way : use CNC controller SD and launch gcode from CNC controller or use SD from remote… same as when you are using you computer your computer. it has serial (wired) WiFi (TELNET) or BT connection
Happy to know you receive your parcel,
You can put message directly on Tindie for better communication.
To answer your question here :
The device is already programmed to use,
You can change parameter following those instruction
WiFi settings can also be changed using the SD card. So you don’t need to recompile and reflash the firmware. To modify the WiFi parameter with the SD card, you must put a file named “wifi.cfg” (respect the case) at the root of the SD card. The file must contain 3 lines with:
WIFI = “ESP32_ACT_AS_STATION”
PASSWORD = “your password”
SSID = “your access point”
You can only modify: “ESP32_ACT_AS_STATION” (change to “NO_WIFI” or “ESP32_ACT_AS_AP”), “your password” and “your access point”
Once downloaded from config.h or from the wifi.cfg file, the settings are saved in the ESP32 and are reused until new settings are downloaded via the SD card.
So you can delete the “wifi.cfg” file from the SD card after the program runs once.
SCREEN CALIBRATION
If you want to recalibrate your screen, you can force a recalibration from the SD card. To do so, you have to put a file named “calibrate.txt” in the root of the SD card.
The content of the file does not matter (only the file name). Remove the file from SD card once calibration is done in order to avoid to do it at each power on.
