Board : Flashforge CoreBoard (all Rev.) MCU : STM32F407xxxx (4 lasts letters and numbers, are just Package, Ram and Flash Size) Printers using all same board: Dreamer, Dreamer NX, Inventor, Dremel 3D20… Bootloader 64k @ 0x08000000 Firmware @ 0x08010000 I got all the working setti…

the zip files contains all pinout system clock config spi/i2c/usb ADS1118 converter .h and .cpp STM32F407ZG 168Mhz 192KB ram / 1MB flash Bootloader at 0x08000000 Firmware at 0x08010000 all needed info.zip (5.4 KB) and most important part of the schematic diagram: [core_part1]

Support for the ads1118 is in my repo for the Makerbot Replicator2(x). I don’t see any reason you can’t grab two files and use it as is for that board: src/ads1118.c klippy/extras/spi_ads1118.c. [image] GitHub - dockterj/klipper: Adding support for MakerBot Replicator 2 Adding support…

Thanks for your fast response… to answer your question about hotend… some have 1 hotend, and some have 2… (just a stepper driver and a mosfet missing) but pinout is always the same… So I’m doing it for the community, there is a lot of 3d printers powered by this board: Flashforge coreboard… (and aft…

[image] CrazyMonkey: Also the stepper driver are the old pololu a4988, except that the potentiometer has been replaced by a I2C digipot to control stepper max current… (exactly like mightyboard) You might want to check run-time-stepper-motor-current-configuration The respective code is in ht…

If you are able to flash it I suggest using my repo as it supports all of the hardware you will need. Take the sample makerbot printer.cfg file and change the pin mappings to your board, build the firmware and flash the mcu. If you are able to get this working I can add your printer.cfg and flashi…

@CrazyMonkey Hi, I also have an flashforge dreamer with an rev h board and I am trying to install klipper but I couldn’t create a working bin. Can you please help? Over the last few years have been using klipper on an old printer with an mks robin and don’t want to get back to marlin, but I am n…

Hi, Dreamer finally was solved ? Ihave a dreamer (dual extruder) also and want to go with klipper… @CrazyMonkey mentioned the firmware is encrypted, so if I erase the MCU on the board no any chance to go back to the original firmware ? Thanks,

Sorry to answer so late… but I was away and very busy… And yes if you erase all the sectors of the flash Memory (1-11) you will delete, at the same time, 2 things, that will render your printer un usable, with the original bootloader… Displaying MCU memory content, from 0x0800C000 to 0x0800C01F 0x…

Thanks. I’m not sure what part of the initial setup you are failing at. Typically, when first bringing up a board, you want to make sure you get the “make menuconfig” settings correct and are able to correctly flash the board. Once you have that correct, one goes on to setup all the pins and thei…

Yes you are a source of very good information and solutions… The STM32F407 board was just a test to see what can be done and in how long, So we have moved to the real part of our project… that you can read a bit about right there…
