Older Instructions

I'm using my old Raspberry Pi2 for this Installation. Also, you can backup and restore your settings too, in order to update your Micro SD card being used. I'm doing this to upgrade from an 8GB card to a 16GB card.

Setup Guide to OctoPrint on the Raspberry Pi 2 | All3DP

Step #1 Install OctoPrint Image, first by installing Raspberry Pi Image

Then choose your "Storage" media and then click "WRITE"

Refer: https://www.raspberrypi.com/software/

imager_1.6.2_amd64.deb

Now run "Imager", and choose "Other specific purpose OS", OctoPi

The installation has changed a little bit, since it was originally created, update this file now:

sudo gedit /media/mruckman/boot/octopi-wpa-supplicant.txt

Uncomment the lines following this comment, and enter your SSID and Password for your home network

## WPA/WPA2 secured

Step #2 Eject and Insert Micro SD Car back into the Raspberry Pi 2
You will need to use the Wireless USB Dongle Too

Step #3 Logon to the Raspberry Ii2 via SSH

ssh pi@octopi.local

Step #4 Complete Setup

Password is "raspberry" without the quotes.

Change your password

passwd

Once you are through the passwd tool, run “sudo raspi-config” and hit return on the first option, expand file system, to allow OctoPrint to use the entire space on the SD card for your print files, updates and log files. Then hit tab twice to select “Finish”, and confirm the reboot.

sudo raspi-config

Choose "Advanced Options", "'A1 Expand Filesystem, Enruse that all of the SD card is avilable" and hit [Enter] and then "OK"

Then choose, finsh and accept reboot prompt.

Ender 3 Update Firmware

32-Bit Boards is supposed to make things MUCH easier now.

Refer: https://tutorial.cytron.io/2021/08/19/firmware-update-for-32-bit-controller-board-on-ender-3-pro-or-v2/

Our Board Version is 4.2.2

August 2021 Release of Ender-3_32-bit_Firmware

This Repo is created for Ender-3 users to update the firmware for the stocked 32-bit board, which is V4.2.2 (Let us know if you have V4.2.7 as we just have V4.2.2 on Ender 3 as of now).

https://github.com/CytronTechnologies/Ender-3_32-bit_Firmware

Unzip to grab binary Cytron_Ender3_V422_Marlin_12Aug20.bin

Marlin 2.0.9.1

Benefits of Marlin 2.0.9 - https://all3dp.com/2/marlin-2-0-features/

Biggest Reason was: Improved thermal runaway system: This beloved feature in Marlin 1 is now even better. It’ll protect your printer from overheating and causing any harm to itself or surrounding objects.

This maintenance release includes a number of fixes and improvements from contributors, testers, and co-developers.

Unzip the final binary 11Aug21_a.bin

Just copy the file on a blank MicroSD card and turn on the printer, it needs to be unique from a previous one.

It WAS necessary to reset the EPROM; otherwise, the printer kept starting with an error.

Format Micro SD Card for Ender 3

Refer: https://www.3dprintbeast.com/how-to-format-ender-3-pro-sd-card/

Windows

Start by bringing the Disk Management window up. You can do this by right-clicking the Start Menu and clicking Disk Management in the menu that comes up.
Find the SD card in the lists of disks (you should be looking at the bottom pane as the top pane is the list of volumes and not disks). If the labels aren’t helpful, you can figure out which disk is the SD card by looking at the capacity of the disks.
Right-click the volume(s) that belong to the SD card (they are listed right next to the disk) and delete them. Be warned that this process will wipe all of the data on the card.
Upon successfully deleting all the volumes, you should see a pane that says “Unallocated” next to your SD card and no other volumes, which confirms that you successfully deleted all the volumes.
Now, right-click the SD card itself and select Properties.
Click the Volumes tab in the dialog, and look at the partition style line. If it shows Master Boot Record (MBR), move to step 11. You can close the dialog and go back to the Disk Management window after gathering this information.
Right-click the Start Menu, choose Windows PowerShell (Admin), and then type diskpart in the command line that came up.
When the prompt starts showing DISKPART>, input the command
select disk X
where X is the number of the disk. You can find this number by looking at the Disk Management window from earlier.
Upon successfully selecting the disk, you will see the output Disk X is now the selected disk. At this point, all you have to do is to input the command
convert MBR
Upon success, you should see the output DiskPart successfully converted the selected disk to MBR format.
To confirm that the process was successful, right-click the disk in Disk Management, go to Properties, and then go to the Volumes tab once again to check the partition style. If it’s showing Master Boot Record (MBR), all is good.
Bring the Disk Management window up, right-click the box that shows Unallocated, and choose New Simple Volume. Click Next until you reach the Format Partition dialog, and enable the Format this volume with the following settings radio button. Set file system to FAT32 and conclude the process by clicking Next and Finish, respectively.
