How to Prepare Klipper Firmware for Kingroon KP3S Using Fluiddpi
Klipper is a 3d-Printer firmware. It combines the power of a general purpose computer with one or more micro-controllers. It helps you print faster and better. Today we are going to talk about how to prepare Klipper firmware for Kingroon KP3S 3.0 3D printer by using Fluiddpi.
To use Klipper, we need the help of Fluiddpi, it’s a powerful project like octopi and for Klipper. It contains Klipper in its image, so you don’t have to download and install it from the beginning. Of course, we will show you a better plan on Kliiper soon, which is how to use it on Octopi. You can get all the information you need on docs.fluidd.xyz.
Part 1, Flash Fluiddpi
First, visit https://github.com/cadriel/FluiddPI/releases/latest to download the latest Fluiddpi image.
Once you finished, use the Raspberry Pi Imager to flash it. Click “Choose OS”, scroll to the bottom, select “Use custom”, then choose the file you just downloaded. Then press keys to preset wifi(On Windows control shift x. On Mac comand shift x). If you don’t know how, please check our last tutorial on how to set up Octopi to print on your KP3S. Please enable ssh and remember the password. And the WIFI signal cannot be 5G.
After flashing the image, you can set your Pi up, our last tutorial will show you how. If you have an extra SD card, you can switch between Octopi and Fluiddpi, all you need to do is changing the SD card.
Part 2, Update Fluiddpi
Power up the pi, wait for a while, then visit http://fluiddpi.local to go to Fluiddpi’s dashboard. Please make sure your computer and pi are at the same network. If you don’t have a WIFI adapter, you can use cable network to instead.
Scroll down to the bottom, click the gear icon, update everything to the latest, it will take some time.
Since Klipper has changed its configure rules recently, the old “printer.cfg” files you download is no longer working. So we will use the latest Klipper as a start, and next time we will show you how to config this version to print.
Step 3, Prepare Klipper Firmware
Once you finished, proceed to the next step. Open terminal on your computer, enter following commands.
If this doesn’t work, you need to go find out the Pi’s IP address and use that instead of “fluiddpi.local”. For example, ssh email@example.com. Then you need to enter the SSH password.
After that enter the following command to config the firmware.
Then you will enter the config settings. Here are what you need to do:
1.Enable extra low-level configuration options
2.Set the Bootloader offeset as 28 KiB
3.Set the “Micro-controller Architecture” as “STMicroelectronics STM32”
4.Set the Communication interface as “USART3 PB11/PB10”
5.Enter the last option, enter “!PC6, !PD13”, the. Press enter key
Then press Q and enter “yes”, after that, the setup is done.
As for Kingroon KP3S with GD32F303 and STM32F407 version of mainboard, we will publish new tutorials soon.
After that, enter “make” to build the firmware. It will take some time. Once you see “klipper.bin”, you’re successful. Then enter the rest two commands to finish this step.
/scripts/update_mks_robin.py ./out/klipper.bin ./out/Robin_nano.bin
cp out/Robin_nano.bin ~/fluidd/
Next, go to the browser, visit “http://fluiddpi.local/Robin_nano.bin” . You will get a bin file, put it into the SD card. You are ready to flash the Klipper firmware to Kingroon KP3S.
Step 4, Flash Klipper Firmware
Put the SD Card into KP3S, turn it on, the firmware should start to flash. Once you see “100%”, you are all set. Now you are ready to use Klipper Firmware on Kingroon KP3S. We will show you guys how to config Klipper to print on the coming blogs.
