Enable SSH to fix CORS issues for Prusa Link

Hi Everybody,

I recently acquired my first Prusa - a Core One+. Very happy with it so far!

But I want to create a custom web dashboard, relying on the Prusa Link API. However, I face CORS errors:

Access to fetch at 'http://192.168.1.37/api/v1/status' from origin 'http://192.168.1.31' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I found out that I had to allow CORS origin, as discussed here:

https://github.com/prusa3d/Prusa-Link-Web/issues/391

 

To do so, I have to SSH in the Core One, but it's not possible. So I wanted to enable SSH as described here:

https://cdn.help.prusa3d.com/article/how-to-connect-to-rpi-via-ssh_658030

But the Core One doesn't run on a Raspberry Pi, and I can't find any SD card on the xBuddy card!

How can I do that?

 

thanks!!

Florent

RE:

You can't do this on a CoreOne. The Core One doesn't run a Unix operating system so you can't run a shell on it.

If you want to create something custom, I would suggest investigating OctoPrint which runs on a RaspberryPi connected to the USB-C serial interface on the printer.

PrusaLink API is baked into the firmware. There is no easy way to configure it without creating a custom firmware image.

Oh ok that's a bummer; I didn't know that, thanks!

Yeah, going with Octoprint may be an option, but then we "lose" the ability to use the LCD screen which is not ideal. 

I've tried to setup a reverse proxy but it fails to authenticate against prusa links for now. 

I'll continue my investigations!

Thanks
