For those of you, like me, who are into 3D printing, here is a quick, and VERY helpful set of marlin gcodes for your Marlin firmware. It will help you when you have to diagnose the errors on-screen, and it will help you even more, if you use the command sets through octoprint. Now onto the latest GCode as of Marlin 2.0.5

This guide will be specific to the setup for my CR10 S5 with the SKR 1.4 Turbo board

Once I build the firmware in VSCode, I needed an easy way to upload it to the device.

To do so, I logged into Octopi

Clicked on the Wrench icon

Clicked on Plugin Manager

Searched for Firmware Updater

And installed the application

Now I have to log into my Raspberry Pi with Octoprint on it

So I open Putty

Input the IP Address for the PI and login

The I enter the following commands

sudo apt-get install usbmount
sudo nano /etc/usbmount/usbmount.conf
Find FS_MOUNTOPTIONS and change it to:
sudo systemctl edit systemd-udevd
Add these lines


Save and Close the file

sudo systemctl daemon-reload
sudo service systemd-udevd –full-restart


Log back into the PI

cd /media
ls -la
Verify full permissions on /media/usb
For mine, /media/usb pointed to usb0 so I had to run
chmod 777 usb0

Now log into Octopi through the browser

Click back onto the Wrench

Navigate down to Firmware Updater

Click the Wrench in Firmware Updater

Set the Flash Method

For my flash method, using the LPC1769 board, I had to select LPC1768

For the Path to firmware folder, I put in /media/usb

Click test to make sure the path is valid


Back in Firmware Updater main screen

Click Browse

Find the firmware.bin file that you created with VSCode

and Click Flash from file

Now the board is flashing and when it completes you will get the message Flash Successful

Thats it!

Thanks for reading

Hardware that I use:
Raspberry Pi 4 (4gb)

SanDisk 32GB Ultra microSDHC UHS-I Memory Card with Adapter

CanaKit 3.5A Raspberry Pi 4 Power Supply (USB-C)

CanaKit Raspberry Pi 4 Micro HDMI Cable – 6 Feet

Western Digital 500GB WD_Black SN750 NVMe

Plugable USB C to M.2 NVMe Tool-free Enclosure


This is a quick one

Open Pronterface

Connect the motherboard to the computer using USB cable

Make sure any jumpers for USB are enabled on the motherboard (instead of power supply)

In Pronterface, click Connect

You will see the following message

Printer is now online.

Next type in M115 and press Send

Your firmware will now be listed…
