Requesting Help

When you request help via Github issues or Discord we would like you to provide the following information.

Controller Type

What controller hardware are you using? If it is a custom designed controller, please describe it.

Boot Messages

When Grbl_ESP32 boots, it sends out a bunch of messages that describe the firmware version, machine definition and options used. This is very helpful for someone trying to help you with your problem. The boot messages are sent to the the USB/Serial port when Grbl_ESP32 starts up. You cannot use the WebUI or other interfaces, because the boot process will be complete before you would be able to connect. Use the Arduino IDE Serial monitor or your favorite serial terminal to view these messages. You can click the reset button on the ESP32 module (preferred) or send $System/Control=Restart via the serial monitor to force a reset. It will look something like this. Please do not include any other text besides the [MSG .....] lines.
