Voron 0.1 BTT M5P / CB1 ethernet only

[TitusADuxass]

I have a V0,1 which I intend to use in my camper (I can't go for a whole month without printing or tinkering).

Most campsites have crepe wifi and I'd need to change the system.cfg at each campsite which would be a right royal PITA. So the plan is to connect to the printer via an ethernet cable.

I've tried simply connecting the cable but the printer always connects via my home WiFi,  if I switch the WiFi off the printer gets an arse on.

How can I force it to use ethernet?

I think you might need to disable the WiFi service over ssh with a command like sudo ifconfig wlan0 down. This site has some additional options such as making it disabled on bootup.

I tried the first suggestion cron job @reboot ifconfig wlan0 down - no joy

So I added sleep to the cron job - still no joy

Directly sending ifconfig wlan0 down did nothing to the WiFi, but sudo ifconfig wlan0 down works.

My tip - don't put it in your cron job or you'll not be able to ssh into it - ask me how I know...

It looks like eth0 is not activated during a normal boot up.

Their seventh option might fit your scenario better. If you run systemctl | grep wpa then it should show that the service is running. You can then use sudo systemctl disable wpa_supplicant and reboot for it to take effect. After your trip you can use sudo systemctl enable wpa_supplicant and reboot to allow the pi to connect to your WiFi again.

I'll give that a try next.
