#turn light on during a print

I have access to my printer's webui but when I try to turn the light on during a print from it, it says "Modification failed". When there's no active print, it works fine and it also works from the tablet itself. Is this just a firmware quirk that can't be fixed without a full klipper port?

#

First of all, we can't compile the main app yet

#

Second, Elegoo offers no way to run custom apps

#

Third, the source code they've given is not 1:1 with their actual release binary, so stuff may be really jank

#

(I guess binary patching is your best bet)

#

saw someone saying on facebook that an older firmware didn't do this, is there any way to downgrade? (currently on .29)

I'm on .25 and not having this issue

#

If you have homeassistant, install the elegoo addon and then you'd be able to check for print start, and auto turn the light on

I'll set up proper vlans later right now i have it on its own router with ports 80, 3030, 3031 forwarded out and everything else blocked

pliant loom
#

I guess i could try .42 as well since apparently the changelog says it fixes webui abnormalities

sly fjord
#

it does but it introduces others lmfao

#

like unloading/loading not working properly

#

Splendid

I always thought toggling the light mid way was blocked because I was using time-lapse and they were stopping you from ruining the video...

#

Huh

pliant loom
#

i always forget to turn it on before starting a print, that's why i find it annoying

candid trail
#

It lets you start a time lapse without the light?? Maybe its because I got the model that comes with the LED bar

#

Oh huh it does

#

Never realized

pliant loom
#

Yeah i have the bar as well

candid trail
#

Always assumed it forced the light on if you chose timelapse

#

Timelpase options would be great. Doesn't take enough pictures imo

#

For how small they are you could really up the amount

Hello everyone. I also had firmware 1.1.42, updated to 1.1.29 via update.bin. Now it hangs on the logo. Maybe someone has firmware for FEL mode?

sly fjord
#

which logo?

#

that's also scary as FEL isn't the easiest to access

#

and only 1 person has any real experience with it here

arctic depot
sly fjord
#

hm, that's not good

#

yeah you'd either have to desolder your emmc or access it via FEL (although unsure if pd got any headway into accessing emmc via FEL)

arctic depot
#

I connect the printer via fel. I only need the firmware in .img format.

sly fjord
#

you mean like an entire emmc backup essentially

#

i haven't looked into what fel can do but can you read the emmc from FEL? Like create your own .img?

#

If so, you can flip the A/B partitioning back to 1.1.42

#

i've never actually looked at if machines have unique calibrations

#

we do have emmc dumps worst case

arctic depot
#

through fel I can only see the printer. I can't create my own img. Can you send me a dump? to load through fel mode

sly fjord
#

@lusty hatch and @fathom furnace have made images, want the ok first from either of them before i send you an emmc dump

#

I could send mine too but mine is modified with custom firmware and analysis tools

arctic depot

#

1.1.4 isn't that useful, but I can dump 25 as well. I don't care if you share it 🤣

pliant loom
#

unless i guess theyre organized enough to save the calibration data from each printer that leaves the factory by serial number

sly fjord
#

i suppose you're right, yeah

#

the serial in the settings won't match then with the sticker on the back

#

but oh well

lusty hatch
arctic depot
#

so I can download the dump via fel?🧐

#

although I have a great desire to try it😀

lusty hatch
arctic depot
#

yes, all of this is there😉

You can follow the pinout on this page and solder the sd adapter to your mainboard. Be careful, the pads are very small and it's easy to damage your board.

#

If you have soldered your adapter to the board, make sure to hold/bridge the reset button so the cpu/soc doesnt try to read the emmc. If you can get the emmc to show up in linux, send me a dm, I'll send you the dump i made

#

very small

#

I use tweezers normally.

arctic depot
#

I don't have such a shallow soldering iron. So it will be a little difficult to do it. Why can't the developers make a firmware for fel mode? Is there no spl for r528? I'm just a programmer and it's easier for me to program/compile than to solder very shallow parts.

#

@arctic depot still trying to hack this?

#

just found this thread

#

I was able to access FEL using the USB-C port, just had to fabricate a cable by snipping the VCC/Ground wires

#

it's mapped to the same pins as the header that isn't soldered on

#

Actually left Ground hooked up, just isolated VCC

#

works like a champ 😄

#

so if you have an old A to C cable you don't mind hacking up to make a magical FEL cable this should work!
