So I want to take my printer on the road. I'm going to visit my family over the holidays and I want to take my RatRig V-Minion and a couple spools of filament along. My Dad gets to hear all of my stories and has a few prints I sent him but since he's 94 with no computer or smartphone knowledge...He doesn't get to see the printer printing. So I figured, How cool would it be to spend a couple, few hours with him showing him how the printer works in real time. I'll have access to WIFI where I'm going but I need some kind of script or something that would let me change the wifi on my Pi3A.
Is there a way to do this or am I stuck having to SSH in and do it manually? Or worse, open it up and edit the SD card.
