Feature Request: Add support for uploading gcode directly to RepRapFirmware #116

Open oliof opened 3 years ago

oliof commented 3 years ago

Most RepRapFirmware setups are network connected, so it would be nice to be able to upload (and start printing of) gcode files directly from Kiri:Moto. Refer to the Developer Documentation for the REST API.

An example implementation of this functionality in python can be seen at https://github.com/Kriechi/Cura-DuetRRFPlugin

I recently acquired a Duet 2 Wifi for testing exactly this. There are some difficulties, however.

First, DWC needs to present an https endpoint. Browsers no longer allow mixed secure / non-secure.

Second, DWC needs to allow certificates (self-signed ok).

Third, the DWC endpoint needs to be mapped to DNS that matches the ssl certificate.

Last, the DWC endpoint needs to enable CORS headers.

My stop-gap solution was to add a "sender" endpoint to Grid:Host as discussed in this thread.

Grid:Host is an old project of mine that allows Kiri:Moto to spool directly to proprietary end-points or devices on your local network. Subsequently, I have added the notion of GridLocal devices which bounce a print stream off of a secure cloud endpoint. But that will not work in this case because I cannot run custom server code on the DWC.

The Reprapfirmware documentation indicates enabling TLS should be possible (see https://duet3d.dozuki.com/Wiki/Gcode#Section_M586_Configure_network_protocols). I have not tried that myself yet.

I spoke to soon:

Note: TLS has not yet been implemented in RepRapFirmware, therefore T1 will not work.

On another note, RepRapFirmware and DWC 3.2 and later support plugins including for DWC, which should allow custom code. Depending on what change is needed, this may required Duet in a Single Board Computer setup (where a Raspberry Pi or similar runs DWC).

I read up on that. As soon as you depend on an external PI to run code, you might as well run the existing GridHost code which already runs on a PI and will provide spooling from KM to the DWC.
