Thank you for your help. I went back to basics on this issue and dug out several USB cables and tried the board with them until I found one that worked. I have now connected the board to wifi and tested it. Everything seems to work so no nuclear option was needed. Thank goodness..

One odd thing I noticed. When homing individual axes the Z axis would move first. This caused the head bed to collide with the printhead. I have edited the homing .G files to prevent this. Now I am waiting upon a bed-levelling sensor. But all of this is for another time.

OK, I am confused, the board has Wifi, but no erase button. It seems to follow the general layout of the Duet 2 but so does the Maestro. There is a jumper just below the endstop connectors marked erase, no ethernet connection but has wifi. I purchased it a few days ago from E3D online as a Duet 2. Do some Duet 2s not have an erase button?.

I guess I will jumper the erase pins and boot the board. Then try to reinstall the firmware. Unless someone can suggest a less drastic course of action.

Hi, I have just purchased the Duet 2 Maestro, and so far this has not been a happy experience.

I cannot get the board to communicate with a PC at all. When a USB cable is plugged in I get 3 LEDs lit one green and two red. A blue led briefly flashes on the WiFi board and the Diag. led flashes once.

The board is not recognized at all when plugged in. I have manually installed the drivers for the board on both a laptop and PC with no difference between the two. I would try updating the firmware manually, but even this seems to be impossible as there is no erase button that would allow me to force the update to the board. The USB cable is taken from my other 3dprinter where it connects the Smoothieboard to a Raspberry Pi to for OctoPrint.

I did manage to get the Diag led to light by creating a custom config.g and other files using the RepRap configurator, however the network connection still did not work nor would the new config. files allow the board to communicate with either my PC or laptop.I copied these files to the SDCard by installing it in the laptop, as apparently the SD Card cannot be accessed through the USB connection.

After metaphorically pounding my forehead to a blood soaked pulp, is there anyone who can help me as I am now at a complete loss, having spent several hours only to end back where I started. I will answer as best I can any questions.

Please help.
