Octoprint can't monitor SD Card prints
I've been impressed with how well OctoPrint and the Prusa i3 works. I've set it up to print directly from Simplify3D using this workaround. It's convenient, but note that you don't get the failure recovery built into the Prusa is Mk3. That's because uploads to OctoPrint are saved by OctoPrint to the RPi's filesystem, not the SD Card in the Prusa. So the Prusa doesn't know about the print; if OctoPrint fails, so does the print.
Now it turns out that OctoPrint can see the SD Card files; just be sure sure that its file view is not set to hide them. And you can start a print from the Prusa SD Card. But OctoPrint can't monitor the print as it proceeds, showing progress its gcode viewer. That's because the Prusa doesn't emit the gcode to OctoPrint, so OctoPrint has no idea what the progress is.
So:
1. People considering OctoPrint may want to be aware of these details.
2. Please correct any of my findings.
3. Have you found workarounds or other ways to manage these issues? Ie, get the Prusa power failure protection or progress with OctoPrint?
4. is there a way to have the Prusa emit some progress to OctoPrint for SD Card prints?
