DWC on SBC plus Repetier Server

[Marcossf]

Hi everyone:

We have installed Repetier Server on the same SD on the Raspberry that controls the Duet 6HC.
We can access DWC indistinctly through the assigned IP, and the Repetier Server on the same IP but on a different port.

Example:
http://192.168.1.191> Shows DWC
http://192.168.1.191:3344> shows Repetier Server

The question we have is how to connect the printer from Repetier to communicate with the DWC to 6HC board does.
Under normal conditions with Repetier Server and with another non-Duet board, it would be done via USB from the RPI to the board, configuring the serial port on the Repetier Server.
But, in this case, the RPI is connected with the flat cable to the 6HC, and uses GPIO, so there is no serial port detected as Duet. We would rather not have to connect via USB externally.

Could this be solved or its impossible?

We wish we had both control interfaces at the same time, DWC for technicians/support/troubleshooting and Repetier Server for basic end users.

Apart from the GPIO communication problem (sic) it seems that the rest can coexist perfectly. This GIF shows it:

I know that someone has already achieved it but we do not know how he has done it, or if they do it in the same way we propose.

Any ideas??

It could be solved, by modifying Repetier Server to interface to the Duet via Duet Software Framework instead of via USB.

@dc42 Thank you, we will try this way.

We could solve it splitting the power supply from Duet and RPI and connecting thru USB to Duet but mantainig the GPIO flat cable, removing the jumper in the middle.

This way we got access DWC (GPIO) and RS (USB) and control the printer indistinctly from any of enviroments.

Ideally would be to use same GPIO for both but we need to learn how to.

We're still far form completion this project, but it seems promising.
