grbl Status / Light-Tower Controller TTL UART

All projects will be hosted on https://github.com/grbl-io in the future

This project is based on ESP32 & GRBL 1.1 for all CNC & 3D printing applications

This project is the start for more projects like grbl DRO, Wireless Pendant, CNC Panel...

New Version Date 28.02.2023 without M5 Lib's - > for Universal ESP32

The Light Tower is already supported by 4 M5Stack ESP32 boards.

Flow of functions: (grbl Light-Tower Controller)

• continuous sending of character ? to CNC Controller
• receive all Status messages from CNC controller
• grbl Message type recognition
• parse message reportData Contents
• Provide all values in local variables
• Shown 8 Status on the display of the Atom Matrix (3 or more Colors)
• Shown 3 (or more) Status on the Light-Tower
• Each LED has 4 modes: OFF, ON, Blinking, Flashing.

Signal Light Tower by default

• Idle = green on
• Alarm = red flashing
• Checkmode = red blinking
• Run = orange on
• Hold = orange on and red flashing
• Jog = orange blinking
• SafetyDoor = red flashing
• Sleep = all off
• Config Alarm = red blinking

Connect

• Connect RX to TX and TX to RX (M5 crossed to CNC)
• Look for 3.3V or 5V Input / Output levels depending on the board.
• Depending on the board, the 5V can also be plugged in directly on the CNC board.

Selection of the UART

• you can use RX & TX directly on the controller. (if you don't use the USB port simultaneously)
• Some boards / Firmwares offer a separate external TTL UART connector (eg FluidNC)

Connection signal tower

• A suitable circuit can be built with the DiY Protokit. (or similar)
• I will publish a circuit proposal shortly.

used libraries (Visual Studio Code & PlatformIO / Arduino )
All libraries are automatically installed with PlatformIO
All important parameters are controlled via the Platformio.ini.

The code is easily ported to any Arduino board with hardware UART.

GBL compatibility
It should support GRBL from the current version 1.1 https://github.com/gnea/grbl/wiki/Grbl-v1.1-Interface

final word
I am happy about every reaction in the issues.
I will write detailed instructions in the next few days. WIKI

hardware design

I am looking for people who would like to help with hardware design.

my applications

• Solidwork 2022
• Target 3001

I have a fully automatic SMD mounter MV-10

Preparation for different ESP32 boards

Preparation for different ESP32 boards (possibly also other Arduino boards)
... The first tests are successful
24.02.2023 Board -> Atom-Lite --> Atom-Matrix --> Atom-PSRAM

24.02.2023 debug flags in Platformio.ini for Light Tower
-D FLAG_PIN_LIGHT_TOWER_RED=19
-D FLAG_PIN_LIGHT_TOWER_ORANGE=23
-D FLAG_PIN_LIGHT_TOWER_GREEN=33

24.02.2023 first debug flags in Platformio.ini for UART Pin's
-D FLAG_PIN_RXD_UART_TO_CNC=26
-D FLAG_PIN_TXD_UART_TO_CNC=32
24.02.2023 Launch for multiple board's in platformio.ini

grbl parser as a library Haven't found any useful projects yet

If you know a project that is worth looking at, I'm happy for every tip.
For further projects, the parser must be relatively complete.

DRO, Pendant, Remote control, gcode stream ....

Controlling the pins with build_flags in platformio.ini
