What happened?

Description of the problem: When powered on, several I2SO output LEDs remain lit. 5V LED ON, RS485 LED ON No communication with the FluiDial pendant. No communication possible with “Bcnc” via USB. No access possible via WIFI. “Reset” button with no effect. After 10 minutes under power, no change. New power OFF then ON. LED 5V and RS485 ON. No communication with Fluidial, nor with “BCNC”. The system has not started, is not running. The ESP32 module is very, very hot, abnormally hot. (comparison made with another ESP32).

No response

Other Information

Web Installer seems to work, but after loading the card still does not start. I sincerely think it's a hardware problem (defective ESP32?).

The machine worked fine for about a month with no problems

This is all the information that I can provide you, following the Mail from Bart Dring of 05/09/2024

IMG_20240902_203331 IMG_20240902_203135

Please arrange to replace this card under warranty, as I see no other solution to resolve the problem. I of course remain at your disposal for further information if necessary.

I agree, it does sound like the ESP32 has failed. I can direct Elecrow to send you a new one. The latest version uses an external antenna which is included. Is that acceptable? See the Elecrow product page for details.

ESP32 failure is pretty rare. I think there are 3 things to watch for in the future.

Overheating. Make sure it is in a well ventilated place with airflow above and below (if possible) the controller. You can set the $WiFi/PsMode to MAX or MIN to run cooler with virtually no impact on normal WiFi performance.
Expansion port. The only unprotected ESP32 pins are on the expansion port module socket. If you are using this for displays, etc be very careful about the wiring. Use good quality shielded wires and filters to prevent noise, spikes and shorts from getting to the ESP32. It does not look like you are using this, but a few people have broken the ESP32 this way.
Power Supply. Be sure to use a good quality power supply. Note: Your use of red and green wire markers is inverted from standard practices (Red+, Green-) and could lead to misconnection.

MichelBattistella commented 2 months ago

Thanks for the quick handling of this issue. The version with the external antenna suits me very well. Please ask Elecrow to send me this card. I take note of the three things to watch out for.

As for cooling, I don't think I have any problems. Cooling with 2 80mm diameter fans. I will set $WiFi/PsMode to MIN.

Expansion port. Thanks for making me aware that the expansion module pins are not protected. I use FluiDial plugged into these pins. I checked the wiring several times as recommended. (as specified in the FluiDial WIKI) The whole thing (6x CNC and FluiDial) worked correctly for a month The cable used is shielded. As the expansion module pins are not protected, wouldn't it be wise to prohibit plugging or unplugging the pendant while the board is powered on. Looking at the FluidDial Pendant Wiki, I couldn't find anything about it.

Power Supply I use a 24V regulated and adjustable switching power supply. No-load output voltage: 24.3V You are a very good observer, yes the colors of the wires are not right. In the photo you saw, I am using, for testing purposes, a 12V power supply whose + and – outputs are reversed.

But don't worry, I know the rules. I'm 68 years old, I'm retired and I do it all for fun. It is only a continuation of my professional life of 39 years in the fields of machine tools (Sinumerik, Fanuc), robotics and Motion control (simotion) within the company Siemens in France. Drives and the G code have no secrets for me. Thank you again for the flawless handling of this issue.

Given your experience, perhaps you could monitor the FluidNC Discord server and offer advice to newcomers who often have trouble with basic CNC issues. The FluidNC developers are swamped with questions of all sorts, and would prefer to spend time on actual issues with FluidNC, instead of fielding questions that are more generic in nature.

bdring commented 2 months ago

I have authorize Elecrow to send you a new controller.

Expansion module: There is some more information here.

MichelBattistella commented 2 months ago

I am flattered that you thought of me to do what we call in jargon the “hotline”. But unfortunately I will disappoint you. I don't want to commit to a task that will take a lot of time. Also, English is not my favorite language. I devote my time primarily to my hobbies, one of which is the CNC, and to my family and grandchildren. I would probably watch the discord server occasionally. But I don't promise anything. Good luck and keep the wind in your sails. Thanks again to Bart for handling my problem.
