I got the complete kit of Raspberry pi 3 model B+. Everything is Good my aim is to communicate with the printer by WiFi I have downloaded the octaprint software to the 3-D printer and dumped the image file into the SD card by giving my WiFi router settings but the pi is not connected. One of your guys told me in call to reboot or reflash the SD card i tried doing it but unfortunately i am unable to connect to the WiFi. Is there anyway that I can connect to the WiFi by giving the username and password in a text file of octoprint software. Can anyone helps me with this?
