    ESP3D

    ESP3D

    FW for ESP8266/ESP8285/ESP32 used with 3D printer

    This firmware allows not only to have a cheap bridge between Wifi and serial, but also to have a web UI to configure wifi, to monitor 3D printer and even control it, and to make things easy, UI is fully customizable without reflashing FW. Firmware should work with any 3D printer firmware (repetier/marlin/smoothie ware using GCODE) if the serial connection has a correct setup. I currently use it with my personal flavor of repetier for Due based boards. The web interface files are present in the data directory but UI has its own repository ESP3D-WEBUI. Use GPIO2 to the ground to reset all settings in a hard way, 2-6 sec after boot / not before!! Set GPIO2 to ground before boot change boot mode and go to special boot that do not reach FW. Currently, boot takes 10 sec - giving 8 seconds to connect GPIO2 to GND and do a hard recovery for settings. Complete configuration by web browser (Station or Access point) or by Serial/telnet commands.

    Raspi - Home Server

    Un piccolo server domestico con il Raspberry

    Immagine per il Raspberry PI che implementa un server domestico per i seguenti servizi: NAS (collegando dischi USB alle porte del Raspberry) Print Server Media Server (DLNA) Scanner di rete (Permette l'accesso via rete ad uno scanner) Inoltre è installata l'interfaccia web RPI-Monitor che consente di visualizzare via web lo stato del dispositivo. Tramite interfaccia web è possibile gestire: Amministrazione del dispositivo (tramite WEBMIN) Stampanti (Tramite CUPS) Scanner (Tramite PHP Server Scanner) Accesso in ssh (tramite shell in a box) Caratteristica interessante è il fatto che è un server headless (quindi puo' essere operativo senza alcun monitor e tastiera). Anche la parte Wifi (SSID e Password) sono configurabili con un fiile di testo presente nella partizione di boot (che è in FAT32 e quindi modificabile anche da S.O. Windows). Una volta collegato alla rete il dispositivo è visibile tramite il nome raspberrypi.local (o raspberrypi)
