Paneldue not showing files sliced in PrusaSlicer

[Hey_Allen]

Please disregard...
I just had an idea, and checked how many jobs were stored on the Duet (and how large they were) and found that once I cleared out a good few that were old data, everything displays.

That said, the PanelDue was not displaying quite a few files, and a wide variety of ages and sizes were invisible for some reason.

After purging ~150-200MB of gcode, everything appears to show on the PanelDue, including some I thought I'd deleted from the Duet, and were still stored on it.

As the title says, the only common thread I can find is that I recently started using PrusaSlicer, and the files that I slice in it do not show up on the files list on the PanelDue, but all the files sliced in S3D show up normally.

Looking in the Web Control Interface, they are all present, and in order that I uploaded them, most recent first, the PrusaSlicer files most recently.
They print as expected, if managed from a PC or even my phone. I just can't see them on the Panel Due.

Duet2 Wifi
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)
Duet WiFi Server Version: 1.23
PanelDue v1, 4.3", Firmware 1.23.2

I can update the display to v 1.24, but I'm not seeing anything that looks applicable in the update notes, so I didn't want to push my luck and potentially have a failure if it's unrelated.

@hey_allen I'm glad you found the problem. Yes there is a limit to how many filenames PanelDue can receive and sort. The limit is higher on version 3 hardware than on versions 1 and 2.

@dc42 Considering that this is an early board, pre-ordered just after the beta boards, I imagine many things were updated later on.

I've purchased a couple of Duet2 Wifi boards since, and my work just purchased a Duet2 Ethernet, and I'm always a little amused as I see the improvements between each generation.
We bought a PanelDue 5i for the RailCore that was just built at work, and I'm tempted, but my 4.3 generally works fine...

@hey_allen you could buy a version 3 PanelDue controller and use it with your existing display. You would then be able to run the latest PanelDue firmware.

Hey @dc42, what is then the maximum number of files which can be received?

[dc42]

@mfs12 from FileManager.cpp:

#if SAM4S
// We have 64Kb SRAM on the SAM4S4B so we can support larger file lists
constexpr size_t FileListSize = 4096;
constexpr size_t MaxFiles = 200;
#else
// We have only 32Kb or 48Kb SRAM on the SAM3S2B or SAM3S4B
constexpr size_t FileListSize = 2048;
constexpr size_t MaxFiles = 100;
#endif

@dc42 thanks.
