We’ve had our x carve for a couple months now, after assembly we’ve probably done 20 or so cuts with minimal issues. Yesterday I was doing the same cut repeatedly, with minor change, and after one of the cuts, the controller simply shut down and disconnected from the computer.
The power LED on the E-stop side will no longer turn on, indicating that the controller logic and stepper drivers are not turning on for some reason, although the power supply and power board are, as indicated by the power led next to the switch and the fan spinning.
I have checked the E-stop, power reset both the computer and controller multiple times, and used multiple usb-b cables in different usb ports. I opened the controller and checked all connections and didn’t see anything immediately obvious as to what went wrong such as component failure.
In windows device manager it appears as a “USB Serial Converter”, although I don’t know if that at all changed since it was working. When the estop is pressed, the USB device disconnects, indicating that the logic board and usb controller at least receiving power, but yet the LED remains off and it will not connect.
If anybody has any idea how to fix this or why it might have happened it would be appreciated.
Thanks
