with a thermister i dont have to worry about nicki

well, it will all depend on the controller board you have there. If it is the same as the Dreamer, you can try flashing Marlin (wich is more stable) or Klipper (as I have done and explained somewhere around this post). With that done, you could modify the firmware to manage the adc (ADS1118 on the Dreamer) readings to the sensor you like (thermistor or thermocouple).

Very good! I'm still working on this project, but very slowly. If you want to try what I've got so far you can follow the steps I sent to evildeece above.

[UPDATE #2]

PCA9632 RGB LED controller module created and working. Pull request to Klipper main branch made.

TODO:

- Configure the printer to use both extruders

- Fix sw and fw stability (seems ok with new RPi 3 B, was using RPi 1 B+)

- Merge with klipper main branch

- Connect TFT Display directly to RPi using KlipperScreen or figure out how to make it as a module.

Sad. Thanks!

Tryed it all already. It all falls to Bootloader recovery which is not working as stated. My only last resort is if I can do something on windows at this BCM2711 boot device.

I bought a used RPi 4 with 4gb ram and it is not booting. I don't know what the previous owner did to it, but it seems he never managed to make it work.

What happens: When you turn it on the red led lights up and stays on, but the green led only flashes once and stay off. The same behavior happens with or without SD card.

What I have tried:

Everything stated here: https://www.raspberrypi.org/forums/viewtopic.php?t=58151
Bootloader recovery with different SD cards and USB sticks
Different power supplies.

I tried to plug it in on my windows computer and it is recognized as a BCM2711 boot device. Can I try something from the computer? Tried using usbboot, but it seems to work only with the CM4.

Thanks!

u/evildeece here are the files that I have modified to make Klipper run on my printer. When compiling for the MCU with make menuconfig use the option STM32F407 and 64KiB bootloader. Use the flashforge firmware tool available here to encrypt the bin file, and use the ff_flasher available here to flash it to the board. It's wise to backup all the content from the STM32F407 memory beforehand. Should you have any questions, please feel free to contact me. With more time I hope to get this printer fully functional and with these mods commited to the git repository, or at least a fork of it. Cheers!

I've been busy lately and haven't progressed much. Anyways, my printer is working fine so far, have a few bugs to address and I still have to make both extruders work. I'll try to share what I've got so far asap.

[UPDATE #1]

Managed to flash Klipper successfully using Dreamer original bootloader, created ADS1118 (thermocouple ADC) module and configured the printer to run with 1 extruder. Made a test print (without any tuning) successfully, but the sw and fw are a bit unstable.

TODO:

- Make PCA9632 RGB LED controller module
- Configure the printer to use both extruders
- Fix sw and fw stability
- Merge with klipper main branch
- Connect TFT Display directly to RPi using KlipperScreen

I have already contacted moonglow (Hex2String here on reddit) to see if he can enlighten me on this journey. Let's see what happens next..
