OctoPrint-FirmwareUpdater VS Neptune_3

After reading some more seems like you CAN do it, but I was either too scared or didn't know about it in Mid-2021

Firmware Updater Useful for flashing firmware to printer without having to use sd card. Frees up an sd card for me

I have 2 skr 1.4 turbo boards and before I switched to klipper I always updated my firmware using the firmware updater plug in for octoprint. On the github page it guided you through setup for that board family. https://plugins.octoprint.org/plugins/firmwareupdater/

I followed the install instructions from this link. I installed the python 3 compatible version of heat shrink.

Method 3 (Through Octopi) - I installed Anaconda to download the firmware updater for Octopi found here (https://plugins.octoprint.org/plugins/firmwareupdater/) but cannot install it through the command line. I get "python setup.py egg_info did not run successfully.". Tried upgrading pip to no avail.

if you have an Raspberry pi you can try https://plugins.octoprint.org/plugins/firmwareupdater/

I'm not sure if this OctoPrint plug-in works with the neptune 2 but it's worth a shot. https://plugins.octoprint.org/plugins/firmwareupdater/

You need a plugin called Firmware Updater.

Only if you already have Binary File Trainsfer setting enabled in Marlin. So you might be stuck since that's not normally enabled. But when it is enabled, it does work. I only update via octoprint anymore. https://github.com/OctoPrint/OctoPrint-FirmwareUpdater/blob/master/doc/marlinbft.md

My first attempt with the M600 code did nothing, the M600 command was ignored. For my second attempt I tried using the M117 + M0 code, the head moved away from the print, but then started printing again right away. The print continuation was not quite aligned and the print failed (filament being deposited was not attached to the main print). I have some questions: a) The closest post I could find was, https://www.reddit.com/r/ElegooNeptune3/comments/10csnsj/filament_layer_change_what_is_the_current_best/ which suggested using M117 before M0. I used that in my M0 attempt. The screen indeed did change modality, but unclear if the M117 helped or not. Just using M117 and M0 was not enough to make things work for me. b) The first thing I did after assembling the printer was updating the firmware (both screen and board). The board firmware binary file path indicates version V1_1.0.5-Beta (latest version indicated at https://github.com/NARUTOfzr/Neptune_3) however after the "updating firmware" screen, the screen UI still indicates firmware 1.0.2; is this expected or I have not successfully updated the firmware? c) I am sending my prints to the printer via the Mintion BeagleCamera ( https://www.mintion.net/beaglecamera ) does this somehow affect the behaviour of the M0 command ? Should I only use the SD card when trying to have pauses in the print? Being able to introduce more than one color in a print would significantly expand the realm of possibilities. Help and suggestions most welcome.

Yes. You can find the firmware here. The beta firmware hasn’t given me any issues, so don’t hesitate to try it. Just remember, if you have any different e-steps, PID tune, etc they will be reset to original values.

You can find the firmware at https://github.com/NARUTOfzr/Neptune_3 , at the end of the page there is also a brief description about the update. In a lot of cases it's best to update screen and board firmware (screen first).

https://www.elegoo.com/blogs/3d-printing/elegoo-neptune-3-fdm-3d-printer-support-files or more specifically https://github.com/NARUTOfzr/Neptune_3 as i said i've never done this myself, but when scrolling to the bottom there's instructions for updating the screen firmware, and the motherboard firmware. do this at your own risk i know nothing either 😅

Please update the latest version of the firmware via the link below. https://github.com/NARUTOfzr/Neptune_3 You can refer to this tutorial when updating the firmware. https://youtu.be/m6vp1q083sI
