Using PanelDue SD card only for gcode files possible?
-
Is it possible as per title?
What are the pros and cons?
I would like to take the wear load from the built-in SD card in the Duet 2 WiFi. Besides, it gets full from time to time.
If this is possible, are there any constraints or conditions I should take care of? For example, is the folder name "gcode" mandatory? Will be the gcode files automatically available for printing, simulation... (whatever) in the DWC?
What is the max. SD card size (GB) supported by the Paneldue 5?What other uses is the PanelDue SD card suitable for? Doing backups of the SD Card in the Duet 2 WiFi for example? Or to write the output of a diagnose command (which tends to be quite verbose).
Thanks in advance.

@Triet if the SD card in your Duet gets full from time to time, either you must be doing a very large amount of printing, or you are using a very small SD card. You can buy a larger, faster card. Even cards larger than 32Gb can be used with the right FAT32 formatting tool.
If you are worried about wear on the card, I suggest you replace it every year or so.
You can certainly print from the PanelDue SD card if you wish. You don't need to use any particular folder structure, you can put print files in the root if you wish. The hardware interface to the PanelDue SD card is much slower then the interface to to the Duet SD card, so uploading files via DWC will be slower. If your print file contains a lot of very short moves in succession then you might see the print slow down for those parts.
DWC will always default to the Duet SD card, so on the Jobs page you will need to tell it to switch to the PanelDue SD card.

@dc42 I was using
M929 P"eventlog.txt" S3
and that file was growing off one's guard - I disabled that. But perhaps I could write that eventlog.txt directly to the PanelDue SD card.
Yes, lots of small segments in the gcode files due to "extrusion rate smoothing" - the only means to avoid abrupt extrusion changes between different lines of different features - as long as Adaptive Pressure Advance stays unusable in RRF (due to the pauses that PA changes cause - fixed in Klipper's last release, by the way...). -

You can specify the PanelDue SD card using
1:/, see https://docs.duet3d.com/User_manual/Reference/Gcodes#filenames-and-pathsTry:
M929 P"1:/eventlog.txt" S3Note that the PanelDue SD card interface is much slower than the onboard SD card.
