Reconnecting your Flux Delta printer by USB and trying access SD card in the printer, enter you password and it should work.
I mentioned earlier that there is no USB connector on my FD - that one broke off very early (as happened to many FD owners). Anyway, there is a hidden serial port which gives access to the machine in the filament compartment, and on my help request I got a special USB cable from Taiwan with some USB-2-serial hardware built in. Using that, I can now happily connect my FD to the computers here again.
Printer not recognized again after SSID and WiFi PW Change
Printer sent back but broken
hi, i had the same problem when i got my Flux Delta +, you will need a wifi router for wifi setup. this is if you have wifi : its pretty easy i contacted support and they walked me through,
first power up the printer then go to you pc and download the latest version of Flux studio i dont recommend downloading the unstable one as its very buggy, take the latest stable one you can download it from here www.flux3dp.com/downloads
when you’ve got flux studio setup leave it aside (your machine will still not be connected). ok now to the connection part, check the flux delta button and make sure its white, if its not remove the power and plugin again. then go to your wifi settings and find the flux delta + hotspot, and connect to it, when it asks for the password put ‘‘flux-delta’’ without the quotes then when you connected go to flux studio and press ctrl+N then it will open the add machine menu press add machine through wifi and it should detect it (you should be connected to your flux delta hotspot), then simply setup your machine name and password and you should be ready to go! .
USB: you will have to install the usb driver (available on the link above) then open flux studio (must be the latest version) and connect your machine with your macbook pro then ctrl+N and press USB connection and it should be detected. if not then im afraid you will have to get a router or use a data hotspot with your phone for the first time.
other things: i had flux studio 0.6.3 and the wifi connected i had to upgrade to 0.7.3 to get it connected through USB.
Hope this helps! NOTE: this reply was intended for someone else so it might not be exactly what you wanted. hope this helps anyway!
