Sorry to be not precise.

After installing the newest incscape version, it ssems that the usb connection to the eggbot boat is not working.

I gett in inkscape the errormessage:

Failed to connect to EggBot. :(

My next step is to start the adruino ide, where I can connect to the board, as an Arudino ZERO – Native USB Port.

My assumption is now that the PC software is working.
I can see that the USB connection is working, because I get the Serial Nuimber of the board back at a connection test.

Next thing in line is the board itself.
As power is connected properly, I assume that the program on the board is missing.
