Wifi .gcode upload to ESP32-Cam isn’t an option until ESP3D is updated to implement streaming gcode from ESP32’s SD card to Marlin/Board firmware. Tracking item is GCODE Streamer Host definition for 3.X · Issue #243 · luc-github/ESP3D · GitHub
Unfortunately the Octopus SD Card’s SDIO pins, and ESP’s SPI2 pins separately go to the MCU, so, Marlin (or what ever board firmware used on Octopus) need to support.
So, will be running around with SD cards for now. Increasingly curious about RepRap firmware, and likely going to hookup Pi sooner than originally anticipated…
