BLV Cube + Klipper = Ultra fast printing 9000ACC, 500mm/s !

עודכן: 22 בנוב׳ 2021


After long experience with Reprap firmware, I decided to try Klipper.

About two years ago, a good friend of mine (Manu) strongly recommended checking out Klipper firmware. At the time, the Klipper project began to take shape but the documentation was a big mess. Despite the potential, I decided to wait for the moment the system will be more convenient to install and easier for the average user. But to be honest, I was a bit skeptical. Two years have passed and I'm glad to see Klipper has become easier to install and even reliable.


Before I started testing the Klipper, I took my system to the edge of its limits running RRF firmware - At least that's what I thought. Installing a Klipper was a smart move, I felt like I was getting a new crazy printer that prints at ridiculously ultra-fast speed. It was the same FYSETC FULL kit I purchased a while ago with the BLV metal kit - the only difference is the firmware. Very quickly I came to the conclusion that the hotend is not good enough for fast printing, so I decided to purchase the Mellow NF-Sunrise Volcano 24V (Direct drive extruder/hotend weight only 185g), and soon after I found fast printing needs fast cooling so I added twin 4020 blowers and started my tests.


This is a video I took a while ago while testing the machine with Klipper firmware. All advanced settings were disabled and I only calibrated the Extruder and Z-offset. The printing results were amazing, but more amazing is that fast prints were made at speeds I never even dreamed of. It looked like the system is capable of much more than that - mainly due to the aluminum parts and the fact it was designed to withstand loads X9 times greater than now:

Some of the images you watched in the video:


Immediately after I took this video, a long series of tests were started and pushed the boundaries. Then I wondered whether the Duet built-in drivers are my limits? a few years ago as the Tmc-2130 came out, I paid 35$ each for my BLV Anet mod and direct-fed it 24V instead of 12V in order to get more juice (torque). So, in this case, I'm testing a new prototype Board that has not yet been released to the market - It's so powerful... it's just amazing! more details very soon - I promise.


Anyway, I'm now confident enough to share with you all my Klipper files and settings including Superslicer BETA BLV profiles. This will give you a good starting point for getting your printer up and running Klipper.

if you can't wait and just want the files, Just download the BLV Klipper files here:

Installing Klipper


BLV mgn Cube setup for the provided Klipper config

  • FYSETC BLV mgn Cube full kit 3d printer (DUET 2 wifi)

  • BLV metal kit (included in the fysetc kit) - replaces all the printed parts with metal parts.

  • Mellow NF-Sunrise Volcano 24V - Lightweight High flow direct drive Extruder (185g)

  • Twin 4020 blowers as a part cooling

  • official Prusa super pinda leveling sensor - probes fast and accurate (not for glass).

  • FYSETC bed + FYSETC Glass (included in the kit) + magnetic PEI spring steel sheet.

*STL and CAD files for the NF-Sunrise volcano 24v and dual 4020 blowers can be found down below.


In order to use Klipper, you must get these parts too

  • Raspberry PI ( I used raspberry pi 4)

  • USB Type-C cable

  • Fast Micro-SD or SSD USB 3.1 (I used 64GB Sandisk ultra)

  • For input shaper, you would need this Acceleration sensor

Klipper has 2 main parts:

  1. Klipper firmware - installed on the Board

  2. Klipper core files + GUI - installed on the Raspberry's Micro-SD card. here you have 3 choices: Fluidd ( my favorite), Mainsail, Octopi.

Klipper installation guide

I want to thank a special person - David Husolo Who has contributed a lot and continues contributing to the BLV project. My dear friend David prepared an excellent guide that explains step by step how to install the Klipper. David's guide is available HERE


At some point, you would need to upload your "printer.cfg" file. I have uploaded my Printer.cfg and it is available inside the zip file below. please feel free to use it and modify it as you need.

Don't forget to edit the line below [MCU] tag:

[mcu]
serial: /dev/serial/by-id/usb-Klipper_sam4e8e_xxxxxxxxxxxxxxxxxxxxxxxxxx-if00

The correct ID can be found using this command on PuTTY:

ls /dev/serial/by-id/*

Now that you have connected to your Klipper firmware I advise you first read all the Relevant documentation for Klipper firmware, you can do that by checking This official Klipper website.


in the next update, you will be able to choose BLV scheme/Theme from the setting menu (Thanks to Stefano). This is how your panel should be like after you have done installing:

Please note that I added a controlling slider for the COB led light (connected to Fan2 port).


 

BLV Superslicer profiles

The best suitable slicer for the Klipper firmware currently is SuperSlicer. It's an open-source slicer based on Prusa slicer. i managed to create a BETA printer + printing profile that will give you a start point. Please mind, these are the original files I used for some of the tests. In the video, I changed all the accelerations settings to 9,000 mm/s^2 and increased dramatically my speed. Feel free to use any other custom printing profile and share it on the BLV Facebook group to discord channel. I will be happy to mix it with the official BETA profile if it's good.

in order to use SuperSlicer, please download the latest version of Superslicer from this link

Then, download the BLV SuperSlicer profile zip from here:

How to use the BLV SuperSlicer profile:

  1. extract the content of the zip file

  2. copy BLV folder to path: \SuperSlicer_x.x.xx.x_win64_xxxxxx\resources\profiles inside your SuperSlicer installation path.

  3. copy BLV.ini and BLV.idx to path: \SuperSlicer_x.x.xx.x_win64_xxxxxx\resources\profiles it should be looking like this:

4. Open SuperSlicer and Choose BLV and the Filaments set from the configuration screen.
