How to Set Up and Use the FlSun Speed Pad on Your KINGROON 3D Printers

The Flsun Speeder Pad is a newly released product that helps people use Klipper easier. Today we will show you how to set up the pad and use it with your KINGROON 3D Printers. Let’s take the Kingroon KP3S Pro 3D printer as an example. 

Kiipper SpeederPad with KP3S Pro


Step 1 Prepare the Speeder Pad

After unboxing the Speeder Pad, you will get a user manual, a charging cable, and the Speeder Pad itself. Connect the pad to the power, it will turn on automatically.

P2 Check the User Manual


The user manual will show you some basics to use this pad, don’t miss this out. According to this form, you should choose “a”, “b”, or “d” for your KINGROON 3D printers. So, we chose the type “d” and connected it.

Then you need to connect the pad to the local Wi-Fi.

P3 Set up Wifi


After that, your pad will get a local IP address. Use that to enter the Klipper dashboard.

P4 Enter the Dashboard


Then your Pad should be ready to use. The next thing is to prepare your printer.

Step 2 Prepare Your KINGROON 3D Printers

Click this link to get the Klipper bundles for your model. You will be redirected to our Klipper tutorial. We will update the information in it. Scroll down to the bottom, you will find the bundles. Choose and download one.

P5 Download the Bunldes


Then copy the firmware files into the SD card and reboot the printer to flash it. 

P6 Copy the firmware file


Normally the screen turns off when the flashing is finished. If anything wrong happens click this link to flash the stock firmware.

Then the SpeederPad should be able to connect to the printer.


Step 3 Prepare the configuration files

Go to the dashboard, then rename the “printer.cfg” to deactivate it, we are going to use our own files instead. You can delete it or modify it, too.

P7 Deactivate the old config file


After that, update the configuration fines you got from the bundle. You should be able to control the KP3S Pro then.

P8 Upload the New Config files


In case anything went wrong, click “home all” and see if everything is OK. You can operate the printer both on the dashboard and the Pad.

P9 Home all to check


Next, you can upload the G-codes and start your first print. If you haven’t sliced any files yet, start with our files in the bundle. There are two necessary test objects in it.

P10 Upload G-Code Files


Then you can start print.

P11 Start Print


With the Klipper Screen Interface, controlling your printer and using the Klipper firmware is really easy.


It has no big difference from normal printing, but you can tune your printer much easier from now on.  After fine-tuning, printing faster and well become possible. Even if you print at normal speed, the print quality will also get improved.

Step 4 Tuning and Further setup

So, your SpeederPad is all set now. But setting up the Resonance Compensation and the Pressure advance is necessary for using the Klipper firmware.

P13 Modify the Settings for Tuning


To do that, you need to modify the “input shaper” settings in the “printer.cfg” for the Resonance Compensation and the “Pressure Advance” in the “extruder.cfg” for the Pressure Advance.

For more information please check the official website:

Resonance Compensation:

Pressure advance:

For beginners, you can also stick with the original files we provided because the basic settings have been made, and you should be able to get good print quality. Also, we will keep those files updated, just getting the latest one, you should be fine.

Tutorials for setting up the Resonance Compensation and the Pressure advance in the Klipper firmware will be available soon.

Next is adding a webcam. For those who have a USB webcam, it’s a great time to take great advantage of it.

Just put the USB port in the SpeederPad, and you are ready to use it.

P14 Using USB Webcam with the SpeedPad


And a webcam is so useful, it not only helps you monitor the printing but also can make time-lapse videos. Make sure to get one at least 1080P. We are going to make a tutorial to show you how to setup time-lapse in the Klipper Firmware in the future.

P15 Dashboard with Webcam Enabled 

That’s all for today. Hope you all enjoy the 3D printing and have a great time. If you haven’t got a Flsun Speeder Pad, it is now a good time.
