RepPanel - A DIY alternative to the PanelDue with WiFi support

yes 18x or so

Oh cool, I would be interested in one!
Is there some kind of dedicated page documenting the things I would need to get it running. I'm running the Duet 3 v1.01
-
Hi there @PCR I am interested on a set = (PCB, GPIO Headers + ESP32), send me payment details — shipping to NYC 10023.
Also, I might have missed it—where is the repo for the firmware? I am building a PCB making printer (trace, solder paste & drill) that requires some modification to GUI.

The link was in the first note -- but not necessarily obvious as a link: https://github.com/seeul8er/RepPanel_ESP32

@JohnOCFII Much appreciated!

Has anyone successfully running the Reppanel at a Duet3?
I experienced the following problem. The display doesn't start (applying 24V to the Duet) when connected to the 5V supplied by the Duet - in my case just the connector IO_0.
When I reset the Lolin32 afterwards with it's reset button it works immediately like expected. When I plug/unplug the connector IO_0 it starts as well.
I can reproduce this with a spare Duet3 just supplying 24V and Reppanel connected.It must have something to to with the rising 5V voltage of the Duet and the power on reset of the Lolin. The board just doesn't reset properly at boot-up.
I fixed it by applying 10uF to extend the time constant of the R-C combination for boot-up reset. Former 10k+1uF->0.01s, now 10k+10uF->0.1s.
Now it starts like it should...
Now my question - is there already a software reset at start-up or could an additional software reset be implemented?
-
@Nellor Nice investigation!
I did not implement a software reset on startup. Maybe the ESP-Firmware does one. Should be no problem adding one additionally.
If you want a quick fix try adding:esp_restart()somewhere here. That should not slow down the boot time too much.

I finally finished and published my RepPanel case. I used this as a good time to learn a bit about FreeCAD. The FreeCAD design file is included in the Thing.

@pcr tried to PM you, but maybe I'm stupid and can only find the chat option, or have not enough privilige as a new user to PM.
So I wanted to ask if you got a PCB left to ship to me. Please contact me. Thanks!I also looked for the correct option for ordering the display and would aks someone to confirm this is correct. See attached picture. Thanks!

Not stupid at all. The chat option is the PM option.
-
@phaedrux Can someone please help me in regards to the display options so I can order? So I can order.

-
Thanks PCR. This is much appreciated, and for sure will help others in the future as well. Now I can order with confidence

@seeul8er, can you make this firmware running on this hardware (esp32, 3.5", capacitive touch) ? It's not cheap but may be a simple solution for people that don't want to mess with electronics.

BTW, the price of buydisplay.com TFT screens went up significantly due to the global semiconductor shortage.
-
@zapta I know the touchdown project. As far as hardware is concerned it should work just fine. You will need to re-configure the SPI-Pins (meaning you will need to recompile the project).
I have some ideas on a custom board but found no time to get familiar with electronics design, yet.

According to the designer, it uses the 3.5 LCD CTP option from here:
https://www.aliexpress.com/item/32862869103.html
Less expensive than the buydisplay one and allows a single PCB and thin design compare to the buydisplay's panel.
Edit: I ordered a couple of those to play with.

Changelog:
- Fixed crash when no filament is specified
- Macro and Job listings are now sorted by modification date
- Fixed filament load/unload error if no tool was selected previously
- Rebased to custom branch of lvgl (seeul8er)
- Compiled for release/performance
-
@seeul8er any chance of SBC support?
-
@seeul8er Great to see an updated release!
Is there a concern of panel burn-in if the display is RepPanel is left energized for 24 hours? Would a timed screen blank (awakened with touch) be a useful addition?
Also -- sometimes touch input is sensed immediately -- other times I have to press an item four or five times for it to register. Any ideas on what would cause that, or ways to troubleshoot?
Thanks!

@jay_s_uk Not sure what the issue is there. Does Duet Web Control work with a SBC/Pi? RepPanel uses the same API (the older one though) so it should work just fine. Sadly I do not have a Duet3 to test it.
@JohnOCFII
Yes burn-in can be an issue. I always turn mine off if I do not need it. The idea of a screen saver is not new. I'll look into that.
I do have the same issue with the touch screen. Sometimes I need to click twice. Maybe it's a driver issue. I'll add it to the list.For the rest: Is there anything else you would like to see with RepPanel? I might find the time to implement some stuff or even get a custom board design working (not sure about that one yet). Feel free to post here or add an issue in the Github Repository. You can also vote for your favourite one.
Feature wishlist:
- Screen Saver/Power Saver mode
- Improved touch control
- Check Duet + SBC support
- Fix bug: No job displaying on the screen when starting a new job (workaround: go back to main and re-enter "Jobs")
- Listing more than 16 entries per directory
- Use Object Model and new RRF3 API calls instead of the old ones
