Easier switching between DSF and Standalone mode?
-
Most folks will neither care nor use a feature that allows easier switching but as a frequent tester I sure would. How about a new parameter to M999 maybe
P"STANDLONE"that tells RRF to restart in standalone mode regardless of SPI state. Assuming an SD card is present of course.Maybe the DSF when given
M999 P"STANDALONE"can issue theM999to RRF then wait for it to come back and give it a "switch to standalone" mode command before exiting with a code that tells systemd to not restart it.This would also mean that having an SD card present couldn't be the sole means of determining mode. Maybe if there is an SD card present RRF could read config.g and check for some command at the top that says "check with DSF for startup mode".
I guess another possibility is a mode where RRF uses DSF only as a virtual filesystem and stays in control all other ways. Maybe this could use the "switch to another config root" feature already in place for having multiple firmware version available.
Just thinking out loud.

The Duet starts in standalone if there is an SD card, and it can open /sys/config.g.
When running in standalone mode, you could switch to Pi with
M471 S"/sys/config.g" T"/sys/config.g.current" M999Depending on the network configuration in the FAT partition config.g and the Pi network config, you might have to load a different web page. They really can't be the same, the Pi is still up and on the network even when the Duet is standalone.
I don't know of any way to switch back without taking the card out of the Duet; when running in Pi, the FAT partition on the card in the Duet is not accessible. I tried "0:/sys..." "1:/sys...", etc. Those are various directories on the Pi.
-
@Danal Yeah I'm not worried about ip addresses since I have different static ones assigned to the Duet3 and SBC. It's just getting the Duet into standalone mode without having to keep removing covers and popping the card out. I'd use an sd card extender but we've been warned to not do that.
-
Yeah, I believe it will require a change to get more than halfway there.
Be nice if "1:/..." was the Duet's SD, when running in Pi.
-
Thinking more about this, it's be really nice to have the Duet's DS card available while in DSF mode to maybe cache a print file instead of getting it line by line from DSF when the DSF isn't adding any value.

Too bad the Pi
cancan't act as a SPI slave; does the jetson suffer the same limitation? -

Except DSF actually processes quite a few of the gcodes. Non move.

@Danal Yeah but it doesn't do anything special with them. At least not at the current time. I always wondered why the DSF just didn't preprocess a print file and ship the file to RRF to print but that's a subject for another decade.

SPIs works in slave mode
would have been a neat trick to use the same interface and just switch the SBC to emulate a SD card, but Pi's can't do that unless you get another award?

@bearer Not a chance

M23 HemeraToolPlateToolBoardHoles.gcode M24The duet can't do that, the file would be not found. Preprocess and ship... well, then what about M20 (list), and rename and delete and so forth.
So move EVERYTHING back to the Duet. Except, run the web server on the Pi, but not the controlserver (or, probably better phrasing, the control server become a very thin interface.) Right or Wrong, this is not the path that Dave and Chris chose.

I'm not suggesting the current path is Right or Wrong. I was just wondering. There certainly could be benefits to having the DCS send gcode line by line. We're just not at that point yet. Like I said "...that's a subject for another decade." Given that "stay at home" has forced me to have 2 double-decker BLT sandwiches with extra mayo this week, I probably won't live that long.

Good news! Thanks!

If that doesn't work already (have you tried it with the latest RRF and DCS?) then I'm sure it would be possible to make it work.

Dang, man, I need to visit, lockdown or no.
