Any plans to sell the development board?

DirtyEngineer commented 6 years ago

Referencing this post I think Bart has a couple of the prototype development board PCB's available.

I have a few blanks I can sell for $10 which includes US Shipping.

I would like to sell them to people who will actively help with the project. You can determine on your own if you qualify for that.

I've been busy writing a javascript Gcode server(web-app), that is served from an ESP8266. This app is complete, and currently running on a Chromebook as a Chrome-App, driving a Grbl cnc router via USB => UNO Beside file-serving this app, the ESP8266 app will use WebSocket to transfer gcode to /from a directly coupled (software-serial) GRBL/UNO.

This will allow any Browser to host this app and serve Gcode to the machine over wifi via Websocket. Browser => socket => ESP => software-serial => UNO => shield

The completed chrome-app is currently 160k (modular and un-minified). It has most of the capability of UGS including a canvas visualization of a Gcode file, This app fits nicely on the ESP8266 along with the HTML-server/socket-server functionality, so it would be no problem for a single ESP32-core.

I'm a retired C# / Java industrial automation developer with lots of time on my hands. I'm very impressed with the work you've done with the GRBL/ESP32 port. My C skills are limited to Arduino-UNO and ESP in Arduino-IDE, but I have a long history of successful software development experience. I would love to work on an app-server/serial-comm core, for this project. It would be great to eliminate the UNO from my current architecture.

I can envision the following architecture .... ESP Web-Server (esp32-core1) => browser-Gcode-sender => ESP-socket-server (esp32-core1) => core-to-core via semaphor => GRBL(esp32-core0) GRBL(esp32-core0) => core-to-core via semaphor => ESP-socket-server (esp32-core1) => browser-Gcode-sender.

This is why I asked about the availability of a development board. Unfortunately, at 70, my eyes are failing, and I would not be interested in populating/troubleshooting a bare board. II think 'll wait for a functional development board to hit the market, and complete the 8266/UNO software in the mean-time.

Thanks, and keep up the good work.

@nhrones That sounds like an interesting project. When I build another for myself, I'll build a couple of them and let you know. There are only about 6 SMD parts and there are all capacitors or resistors.

You should be able to run a "virtual" machine by just running on the ESP32. Turn off homing and it should behave just fine.
