Question 1

Printer in setup isn't detected / can't find setup code

Accepted Answer

In this guide, we'll dig into what to do when the SimplyPrint setup guide doesn't detect your device while setting up SimplyPrint, or if you can't find the 4-letter setup code.

| Remember to give your Pi / device a couple of minutes! When the device boots for the first time, it may take some time. Be patient for the first couple of minutes, and it'll most likely show up.

|| This guide is only for OctoPrint / Mainsail / Fluidd / Moonraker / Bambu Lab setups - not the Direct Prusa setup

First things first; is SimplyPrint installed and enabled?

Often times, the issue is as simple as SimplyPrint maybe not being installed or enabled.

Make sure you have gone through our setup guide, and maybe repeat the steps to see if you missed something
For OctoPrint setups; go to Settings > Plugin Manager and ensure the SimplyPrint plugin is both installed and enabled. If its' grayed out, it's disabled
For OctoPrint setups; make sure OctoPrint isn't in "Safe mode". If a popup says "Safe mode", just restart OctoPrint to get it back in non-safe mode

Auto-detecting

Make sure you're on the same network

SimplyPrint can only auto-detect your printer if your computer / device you're detecting from, is on the same WiFi / network as the Pi / device running SimplyPrint. So ensure you are indeed on the same network.

Ensure your Pi is powered and connected

Double-check that your Raspberry Pi (or whichever device is running SimplyPrint), is connected t

Question 2

Which cable to use for SimplyPrint / OctoPrint

Accepted Answer

It is important to have the right cable to connect your Raspberry to your Printer. Most printers come with this cable as many use the port on the printer to print through from a computer. If your printer wasn't shipped with a cable, you will need to buy one. This guide will help you choose the right one.

USB C

If the connector on your printer looks like this, you will need a "USB C cable".

The most popular printers that use this connector are:

Most newer printers
Ender 3 S1
Prusa MK4
Prusa XL

Mini USB

If your connector on your printer looks like this, you will need a “Mini USB cable”.

The most popular printers that use this connector are:

Creality Ender Series
Creality CR-10 Series

USB B

If your connector on your printer looks like this, use a “USB B cable”.

The most popular printers that use this connector are:

Prusa i3 Series
Ultimaker 2 Series

Micro USB

If your connector on your printer looks like this, use a “Micro USB cable”.

Question 3

Pick the right Raspberry Pi for running SimplyPrint / OctoPrint

Accepted Answer

If you are in doubt about which Raspberry Pi to buy / use for SimplyPrint, and maybe where to find it, follow this guide.

What Raspberry Pi to pick? And what do I need?

All you need to run SimplyPrint is;

A Raspberry Pi
A power supply for the Pi (important that it's an official power supply for the given Pi model)
An SD card (8 or 16 GB)
A connection cable for the printer

Which Pi to choose? We recommend a Raspberry Pi 4B - it's not super expensive (often cheaper than the previous model), and it handles running SimplyPrint very well.

Here's a list of all Pi's that will run SimplyPrint well;

Raspberry Pi 4B (2, 4 or 8GB ram - only matters if you plan on having multiple printers running on your Pi)
Raspberry Pi Zero W 2
Raspberry Pi 400
Raspberry Pi 3B(+)
Raspberry Pi 3 Model A+ (not the best, but it works)
Raspberry Pi 3

Pi versions that won't handle SimplyPrint very well;

Raspberry Pi 5 - does NOT work yet, due to missing OctoPrint support. Support is coming soon.
Raspberry Pi Zero W (first version)
Raspberry Pi 2 (all variants)
Raspberry Pi B(+)
Raspberry Pi Pico (won't work at all - is not a computer, but a microcontroller) Note that some of the devices on this list might work, but aren't recommended as they're known to cause performance issues that result in bad prints.

Where to get them?

Every country in the world has at least one Raspberry Pi reseller - most gadget-webshops a

Question 4

My camera doesn't work for OctoPrint / SimplyPrint

Accepted Answer

Troubleshooting USB Webcam or PiCam Not Being Shown in SimplyPrint

This guide will help you troubleshoot the issue of your USB webcam or PiCam not being shown inside SimplyPrint. Before diving into the specific steps for OctoPrint, Mainsail, or Fluidd, it's important to verify that your SimplyPrint gateway is set up correctly.

Step 1: Check the SimplyPrint Gateway

First, ensure that you're using one of the following platforms as your SimplyPrint gateway:

OctoPrint
Mainsail or Fluidd (Moonraker powered)

If the webcam is working in your chosen gateway, it should also work in SimplyPrint. If the webcam is not working in the gateway, follow the appropriate troubleshooting steps for your platform.

Troubleshooting camera not working for OctoPrint

Verify that the webcam is correctly connected to the Raspberry Pi or whichever device you're using
Check if the webcam is supported by OctoPrint. A list of compatible webcams can be found here.
Ensure that the octopi.txt configuration file has the correct settings for your webcam. Follow the instructions in the quoted section below for setting up the camera for OctoPrint on a Raspberry Pi.
Restart the OctoPrint service using the following command: sudo service octoprint restart

Once OctoPi’s up and running, it’s time to move to the webcam. Here’s how to configure OctoPrint to use the correct settings for your webcam

Question 6

The Filament Manager feature

Accepted Answer

In this article, you'll learn all about the Filament Management feature in SimplyPrint!

| TLDR; you can create each individual spool, which will then have its own unique identity; we track the spool usage, and can alert you when there's not enough filament on the spool to start your next print - like a virtual filament sensor! Each spool also carries information used by the printer; temperatures, slicer settings, density & more.

What is it?

The SimplyPrint Filament Manager allows you to easily keep track of all your different filament spools, and assign a specific spool to a specific printer, when it's in use! This allows us to track the usage and alert you before you start a print, if the current spool won't be able to finish!

Why should I use it?

Our filament manager is all about information; knowing the details of the material currently attached to your printer, allows us to make your experience a whole lot smoother!

With a spool assigned to your printer, we'll know;

The heating details (nozzle & bed temperature)
How much material is left on your spool
Slicing details (print speed, etc.)
Material cost; allowing us to accurately, on a case-per-case basis, calculate the cost of a print
If the filament is old, and warn you that it might cause bad prints due to the effect of humidity _(we've a
