Duet 3 mini 5 and Octoprint- Over sbc wiring?

[toddel]

Hi guys.

Is a Connection via ribbon cable from duet mini to Raspberry possible or only over usb?

I have a mini5 in sbc mode, if i use it in standalone, is a Connection over that cable possible?

@toddel the SBC port only speaks SPI, which isn't supported by OctoPrint AFAIK. You might be able to use the PanelDue serial port to connect directly to UART pins on the Raspberry Pi.

That said, with RepRapFirmware, running OctoPrint doesn't necessarily get you the advantages you get with Marlin. But I guess you're aware of that.

@toddel have a look at this for using the SPI with octoprint https://github.com/ofligit/dsfprinter

@toddel DSF on the Pi has an API suitable for programs such as Octoprint to send the data through. Octoprint would need to be modified to use it. There is a version of Repetier Server that already supports this interface.
