@Phaedrux said in Duet Web control is not available at time of printing:

Do you have a large number of nested folders?

There are many subfolders (each project has its own folder). But this problem does not depend on the depth of nesting. The interface also freezes if you print a file from the root of the card and from a subfolder.

@Phaedrux said in Duet Web control is not available at time of printing:

Can you share one of your volumetric gcode files?

And where to put this file?

@Phaedrux said in Duet Web control is not available at time of printing:

Yes please test with a new SD card. When you do so, replace the files in the /www folder with a fresh set from the DWC 3.1.1 zip file.

I replaced the SD card with a new (class 10), the DWC has updated the files, replace the cable. As a result, the DWC fell off after 8 hours printing. On the old card it occurred 5-6 hours after printing

@Phaedrux Yes, I switched to 1x16 microsteps. Perhaps the reason is actually in the memory card. I’m not very fast. Today I will buy a new one and check with a new card

Good afternoon!
Problems continued, but less frequently. Most often, the problem appears when you create a folder on the memory card, or transfer to the card volumetric files. Sometimes the interface freezes during long-term work. And it is such that when downloading files pauses printing for a split second.

@Phaedrux
After the transfer of the Ethernet cable from the printer body, hovering stopped interface (tested on a daily print interface can be accessed at any time)

@Phaedrux
Good. After the work is checked.

@Veti
I sent the first command while printing. Printing was interrupted, now only after work I can start printing again. In essence, the main question - after transferring the Ethernet cable outside the printer case, the Web server does not hang up yet.

@Veti
I plan to enable interpolation later
