Printing From Octoprint Wont Allow Me to Adjust Baby Z

Before you first, brand sure that OctoPrint supports both your printer and Raspberry Pi model.

Does my printer work with OctoPrint?

Probably. OctoPrint works with most popular 3D printers. Check out the complete list of supported printers. Chances are your printer is on there.

Best Raspberry Pi for OctoPrint

It is recommended you use a Raspberry Pi 3 or 3+ to run OctoPrint since the cheaper Raspberry Pi Zero is non quite up to the task. In item, the Zero can suffer from massive Wi-Fi interference, negatively impacting your prints. Y'all can also use the Raspberry Pi 4 for OctoPrint, though I recommend calculation a cooling fan since this detail model runs hot.

The easiest manner to set upward OctoPrint on your Raspberry Pi is to use the OctoPi disk prototype, which is basically a total copy of a working OctoPrint installation. Download the OctoPi SD card image from the OctoPrint downloads folio.

After downloading the image, we're going to burn down (or "flash") information technology onto your Pi's Micro SD card.

Connect the SD card to your calculator using a Micro SD card reader. And so, download and install Raspberry Pi Imager.

In Raspberry Pi Imager, click Cull Os, select Use Custom, and then locate the OctoPrint disk paradigm you downloaded. Next, select your SD card, and click Write. The flashing process takes about v minutes.

Note: Alternatively, you lot can compile OctoPrint from source instead. This is useful if you plan on using the Pi simultaneously for something else (which is generally not recommended for performance reasons).

To connect your Raspberry Pi to wifi, we're going to edit a text file on the SD card. Etcher may automatically squirt your SD card after flashing. If it did, disconnect and reconnect it to your figurer.

Locate your SD card in Finder (MacOS) or Explorer (Windows). And so, open the octopi-wpa-supplicant.txt file in Notepad, Sublime Text, or some other text editor. Exercise not apply Microsoft Give-and-take, Wordpad, or any other "rich text" formatting program to edit the file.

Uncomment the lines below, and input your wifi network and password:

            ## WPA/WPA2 secured network={     ssid="my-wifi-network-name"     psk="my-wifi-password" }          

If y'all're using a Raspberry Pi 3B+ or Raspberry Pi 4, you'll likewise need to uncomment or add your country lawmaking in that file:

            # Uncomment the country your Pi is in to activate Wifi in RaspberryPi 3 B+ and above # For full list encounter: https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 #land=GB # Uk #country=CA # Canada #country=DE # Federal republic of germany #state=FR # France country=US # U.s.a.          

Notation: If your state isn't already listed above (e.m. Australia), find your 2-digit ISO 3166-i state code from this Wikipedia article and use it instead.

Relieve and exit. Finally, safely squirt the SD card, put it into your Pi, and connect your Pi's Ac adapter.

For security reasons, I recommend you change your Raspberry Pi's default password.

*Note: if you're trying to beat out into your Octoprint Raspberry Pi (Octopi) via Terminal, then y'all'll demand to use the command

            ssh pi@octopi.local          

You lot can now connect to OctoPrint to view the OctoPrint interface. From your regular calculator, make sure you're on the aforementioned network as your Pi, so visit http://octopi.local in your web browser.

You can as well access the SSL-encrypted version at https://octopi.local, though you lot'll demand to have the self-signed document.

After loading the OctoPrint interface in your browser, you volition run across the OctoPrint Setup Wizard:

Access Control

Use this to set a secure username and password for Access Control. Fifty-fifty if your printer will non exist accessible from an external network, I recommend you set up this up.

Online Connectivity Cheque

This will ping Google's DNS server periodically to ensure your Pi is online, aborting intensive operations if it is non. Enable it, and get out information technology at the default 15 minutes interval.

Plugin Blacklist

This setting prevents unsigned or potentially malicious plugins from being installed on your Pi. I recommend enabling this so that later you can discover amazing, condom, OctoPrint plugins.

This office of the Setup Wizard is important. Enter the details for your printer.

If you aren't sure of your printer's specifications, open your normal slicing program (similar Cura) to view the settings or do a quick Google search.

I'm using the Creality Ender three with OctoPrint and my settings are as follows:

              Form factor: Rectangular Origin: Lower Left Heated Bed: Yeah (checked) Heated Sleeping accommodation: No (unchecked) Width: 220mm Depth: 220mm Height: 250mm Axes: Default** Custom Bounding Box: No (unchecked) Nozzle Diameter: 0.4mm Number of Extruders: one            

** The Axes setting is simply used for manually controlling the printer -- as I slice my models before putting them into OctoPrint, I didn't carp filling this out. However, y'all can if you lot choose; call up the Axes speed settings are per minute, whereas the settings in near slicing programs are per 2d.

Notation: If your printer is an Ender 3, I wrote a dissever guide that covers using the Ender 3 with OctoPrint in greater detail. If yous're using the Ender 3 V2, cheque out our guide on using the Ender 3 V2 with OctoPrint instead!

Now we tin can connect our Pi to our printer! Obviously, this will allow OctoPrint to send commands to and command your printer. To practice this, you'll need to physically connect a USB cable from the Pi to your printer's USB port.

Your printer's USB port is ordinarily located virtually the SD carte slot. It might be a Micro USB port or, for some insane reason, a Mini USB port (the mushroom-shaped ane). I accept no idea why so many electronics still use Mini USB... Perhaps some factory made also many Mini USB ports 10 years ago. Merely I digress.

Using the appropriate cable, connect i of Pi'south USB ports to your printer'due south USB port. Ensure the cable you use supports data (some cheaper cables only support charging). This is the Mini USB cable I used.

Next, nether Connection Settings in OctoPrint, enter the appropriate settings from the OctoPrint wiki.

For the Creality Ender three, the settings I used were:

              Serial Port: /dev/ttyUSB0 Baudrate: AUTO            

Be sure to check both "Relieve connection settings" and "Auto-connect on server startup".

One of the nigh exciting things nearly using OctoPrint is live watching prints remotely and recording prints. And so, let's hook upwards a Raspberry Pi camera. Of course, this is optional but highly recommended.

First, shut down and unplug your Pi. Do not endeavor to connect the camera while your Pi is powered. Then, connect the camera to your Pi and reboot information technology. I recommend using the official Raspberry Pi camera, simply certain USB webcams are too supported. Check out our total guide on the best cameras for OctoPrint!

You lot should at present see the webcam streaming past visiting the OctoPrint Control tab: http://octopi.local/#control

Troubleshooting

If your video feed isn't working, brand sure you connected it to the "CAMERA" (non "Display") port on the Pi. I made this fault since they're identical. If it still isn't working, check to make sure your ribbon cable connections are adept, facing the right management, and that the tiny connector that plugs into the photographic camera itself is seated properly.

I recommend printing the following parts for your OctoPrint setup:

• Raspberry Pi camera mountain
• Raspberry Pi case/mount
• LM2596 step-down converter example (if powering your Pi from the printer)

The verbal models to use will vary for your printer, but you can observe them past searching for your specific printer on Thingiverse.

If you're using the Ender 3, you can find the parts list in this step.

My printer uses extruded aluminum rails, so I mounted my Pi using two M4x8mm bolts and M4 t-nuts. The camera model I found clips directly to the Z-axis stepper motor to give me a good side view of the extruder. Finally, I mounted my step-downward converter on the back of my Ender 3 using foam tape.

Choose whatever mounting method works for you. Only continue in mind the distances between your cables and the extended Raspberry Pi camera cable -- and don't forget how long the camera cable is when the printer is fully extended in the Z-axis!

While you tin can ever ability your Raspberry Pi using a normal Pi Ac adapter such every bit this 1, yous can likewise ability it direct from your 3D printer's ability supply! This is handy for powering the Pi on only when the printer is on and creates an overall cleaner setup. Also, you can save coin past not ownership a separate AC adapter for your Pi.

Because this is totally optional and requires some soldering, I wrote a dissever comprehensive guide to teach you how to power a Raspberry Pi from a 3D printer.

Notation: With either arroyo, it's always important to shut down your Pi properly before disconnecting its ability supply. You lot can practice this through the OctoPrint interface or by adding a Raspberry Pi push button to shut it downward.

At present nosotros need to focus the Pi photographic camera so you'll accept a nice articulate video feed.

Open the Feed tab in the OctoPrint interface. Eye your printer'south bed, place an object in the centre of information technology, and move your extruder just above it. This will simulate performing a print.

Your Pi camera came with a minor white plastic adjustment wheel. Use this small adjustment wheel to turn the camera'southward lens a small corporeality at a fourth dimension (perchance 1/16 of a turn). Check the feed periodically and stop when things are in focus.

You may need to try turning it in both directions. Be patient and you'll have a dainty articulate video feed!

Y'all should never run your 3D printer when you aren't around to monitor it (read: fires and stuff). This is why the concept of OctoPrint centers largely around connecting to your 3D printer remotely over the same network.

Still, if yous're in a position where someone tin monitor your printer for yous and you want to connect to OctoPrint truly remotely -- from anywhere -- it is possible to fix this up.

At that place are a number of ways to accomplish this, but the easiest method is to use the Spaghetti Detective plugin. I wrote a dissever guide on setting upwards The Spaghetti Detective if yous'd like to bank check it out!

Import your first gcode file using the "Upload" button and send your first print to your new OctoPrint-enabled printer. Pat yourself on the back, you're done! Don't forget to update OctoPrint periodically to proceeds access to new features and bug fixes!

Adjacent up: Add an OctoPrint touchscreen to your setup!

Questions? Comments? Did I miss something?

I'd love to hear from you. Post in the comments section below :)

While making this guide I ran into many Ender iii V2-specific bumps and stops, and I've worked through them all so you lot don't have to spend the time.
