lw.comm-server - unified communications server for LaserWeb4

lw.comm-server is the unified communications server for LaserWeb. It is the gateway between the machnine and the frontend and cares about all different interfaces & firmware specific protocols, so the clients doesn't have to care about the machine controller and firmware (as far as possible).

lw.comm-server is based on nodejs 10.x.

Communication structure

The frontend communicates with the server over websockets. Details about the API can be found in the wiki. The server supports several interfaces to communicate with machines.

Supported interfaces

Implemented:

• Serial over USB
• Websocket to ESP8266 (as WLAN to serial gateway)
• Telnet over Network (or WLAN)

Supported firmwares

• Grbl (ATmega328)
• Grbl MEGA RAMPS (Arduino MEGA 2560 + RAMPS)
• Grbl-LPC (for LPC1769 boards like C3d, Smoothieboard, MKS SBASE, Azteeg)
• Smoothieware (actual version of firmware-cnc.bin)
• TinyG (actual version)
• MarlinKimbra (not finished)
• Marlin (not finished)
• RepRapFirmware (not finished)

Preliminary support for manual pulse generators (MPG)

• XHC HB04
• XHC HB04B

Please check the wiki for details about the API.

Install notes with Debian 12 bookworm

I recently upgraded to a new fanless IPC computer and installed Debian 12. I forgot some of the settings required for the lw.comm-server to access the HB04B

• in /etc/udev/rules.d, add a file with the following line: ATTRS{idVendors}=="10ce", ATTRS{idProduct}=="eb93", MODE="0666", OWNER="root", GROUP="plugdev"
• make sure your user is in the plugdev group
• reboot
