I want to connect my laptop without internet connection to my Raspberry Pi4 without internet with Bluetooth. So that I can send the desired file to the Raspberry Pi with my laptop and my 3D printer prints it is this possible is my question is my first time with Klipper.
Thanks for your help
Hello @Dan1el !
This is not how Klipper works.
Klipper is a two part firmware solution:
- The main calculation is done with the part on the Raspberry Pi
- The printer boards works as driver board for the steppers, heaters, sensors etc.
A continuos connection of printer board and Raspberry Pi is essential for the proper work of Klipper.

Hello @EddyMI3D
Thank you for your answer.
The Raspberry pi is always contacted with the printer board.
My question is can I send what I want to Print with my Laptop to my Raspberry Pi with Bluetooth because where the printer is I haven’t Wifi.
(Sorry for my bad English hope you understand my problem )
Ah, now I understand. Sorry for my misinterpretation.
So Bluetooth is meant for a short distance wireless connection, you may try a Lan cable.
For Bluetooth itself: It depends on if there is Bluetooth support with the OS of the Raspberry Pi.
Maybe someone else knows more.
My Laptop is only 3 meter away that will be short enough Or ?
The answer is most likely not so straight forward:
- BT is not really meant to transfer larger amount of data
- Data rate is around 2-3 Mbps
So, printing from this data rate is likely impossible. Transferring data to the host and printing from the virtual sd-card is entirely possible (depending on your ability to suffer)
I need try it with Bluetooth because Chef want it so 
Do yourself and your boss a favor. Don’t use BT. Use an independent WiFi or hard wired network connection, so you are not connected to the “internet”. You may find many solutions in the WWW.
