Prepare tools included in the MK3 kit or get similar from the nearest hardware shop. You will need:
-
Needle-nose pliers
-
Allen keys
-
-
-
Using Allen key release the M3x40 screw.
-
Using pliers cut the zip tie on the cable bundle from the Heatbed.
-
Using pliers cut the zip tie on the cable bundle from the Extruder.
-
-
-
Carefully push all the cables from the side opening, leave them connected to the board.
-
Carefully push all the cables from the top opening, leave them connected to the board.
-
-
-
Release upper two M3x10 screws holding the EINSY board together with the RAMBo cover.
-
Release lower two M3x10 screws holding the EINSY board together with the RAMBo cover.
-
-
-
Slightly release two M3x10 screws holding the RAMBo cover on the frame. DO NOT unscrew them completely!!!
-
Carefully slide the RAMBo cover from the frame. Plugged cables won't allow you more than few centimetres.
-
Separate the cover from the EINSY board.
-
-
-
Locate the opening for the GPIO header on the back of the EINSY board (see the first picture).
-
Carefully slide the RPi Zero W in.
-
Check the header pins are all the way through.
-
-
-
Go to the Settings menu and turn ON the RPi port. Return to the printer's home screen.
-
Now, wait for a few minutes. The RPi isn't a superfast computer and it needs time to boot. Then open the browser and try opening a website: octopi.local
-
If octopi.local doesn't work, please use the following steps:
-
Check your router for new IP address or wait until the address is displayed on the printer's screen.
-
As soon as you have the IP, open browser on your PC and insert it. If the Octoprint webpage loads, you can continue.
-
In case OctoPrint works, turn off the printer and continue to the next chapter: 2. Printer assembly
-
-
-
OctoPrint provided by Prusa Research is tested and is confirmed to be booting correctly. If you can't access the web interface, check the following:
-
Is the RPi port enabled on your printer?
-
Did you enter correct Wi-Fi name (SSID) and password?
-
Is the RPi Zero W correctly plugged in the EINSY RAMBo board?
-
Are you connected to the same Wi-Fi network?
-
In case all hints above didn't help, please visit our forums.
-
Did you manage to solve the issue? Turn off the printer, unplug it and continue to the next chapter: 2. Printer assembly

Great. Bought a prebuilt printer to avoid having to mess with the RAMBo cover and the 100000 cables so everything fits together without pinching wires or bending pins when closing it, and now I have to disassemble it completely to install a Raspberry Pi :/
I’m just going to connect a normal Raspberry Pi with an USB cable for now I guess :)
Hi Joris,
it is a matter of 15-20 minutes to reassemble the cover with RPi inside. We are working on a RAMBo cover with easier RPi installation, but it will take some time.
Is the raspberry pi 3 the same software as for the zero. With the 3 you can use a better cam . And it is independ.
I like to keep the i3 original as possible.
Hi Frank, not 100% sure as the RPi Zero W uses slightly different hardware configuration.
can we use any rpi, don’t care about the looks, just want it to work.. - also does this mean rpi takes over the control of mk3 and no pc has to be on when it’s working (new at this)
