1, Find out your IPv4 address for the computer you are using.
2, Connect the M1 via the USB cable and also connect the ethernet cable to your computer, then turn the power on to the M1.
3, Open the M1 Studio and enter your IPv4 address into the IP address settings but change the last 3 digits so that it doesn’t match the computers IPv4 address, and make a note of it. Save the settings. This will now be the IP address for the M1. The last three digits can be anything.
4, Open up a web browser and enter the IP address for the M1 into the search bar and press enter. You will then see the web manage page for your M1. You can update the firmware from here.
It is worth reading the firm ware instructions on the Dobot web page. The firmware needs to be installed in a certain order.
Once you have updated the firmware, you can just use the USB to control the M1
I hope this helps.
