Spoolman on OpenNept4une

OpenNept4une Spoolman

Spoolman is a self-hosted web service designed to help you efficiently manage your 3D printer filament spools and monitor their usage. It acts as a centralized database that seamlessly integrates with popular 3D printing software like OctoPrint and Klipper/Moonraker. When connected, it automatically updates spool weights as printing progresses, giving you real-time insights into filament usage.

 

I just discovered Spoolman the other day by pure accident. Read about it quickly in a comment on some social media platform and instantly had to look it up. It looks pretty sweet. In the past I have never really needed much organization for my filament. I only had a few rolls of a few colors and did not print very heavily. Since getting the Elegoo Neptune 4 Max I have dumped rolls into the printer. I now find myself with a bunch of half used rolls of filament and if I want to use them I have to eyeball how much is left. Yes my spools have meter and gram indicators but that’s still a rough guess. Spoolman takes the guesswork out of it all.

If you have a printer running Klipper you can probably install and use Spoolman. If you have a printer like an Elegoo Neptune 4 with Klipper – you can’t. Elegoo did something to the firmware that makes it so you cannot update with the current versions out there. Nor can you update the boards OS without breaking things I have read. Moonraker needs to be updated to use Spoolman. There is a procedure I have found for updating Moonraker on the Neptune but I HAVE NOT TRIED IT. I posted it over here on my other post but I will reference it here also. This was my push to install OpenNept4une.

This is my guide/what I did to get Spoolman on my Neptune 4 Max with OpenNept4une.

OpenNept4une

OpenNept4une

If you have an Elegoo Neptune 4 series printer and are in the Elegoo Facebook group you may have heard of OpenNept4une by now. If not, you have now. From what I can tell there are two current thoughts about the Elegoo Neptune 4 series printers. One – the printer has a bunch of flaws and just won’t print properly and it is due to Elegoo’s touch of the Klipper software and installing OpenNept4une will resolve all of these issues. Two – the printer is fine and works fine, but you want community Klipper and to be able to update the software without things breaking. You want to be able to add things and be more up to date following the community with its version of Klipper.

I have not had any issues with my Neptune 4 Max for the few months I’ve owned it, I have printed about 20 rolls of PETG so far. But I noticed Elegoo’s Klipper is a few versions behind and they don’t offer updates much. There are a few things I would like to get play with and get working (Spoolman) and I would like to be able to use KIAUH. Plus I like to tinker. With a stock Neptune you cannot update the OS either, which I don’t like. Anyway, I decided to take the OpenNept4une plunge and I documented my process.

The Wiki/install guide on the OpenNept4une GitHub is fantastic. You can head over there and you should be able to follow that guide, it’s a bit more technical so I decided to write up what I did. I have a Neptune 4 Max so all of these instructions here on my blog are for the Max. They may or may not be the same and/or work for other Neptune 4 printers I have no idea. There are probably other steps for other printers, check the Wiki – you have been warned.

Spaghetti Detective (Obico) on the Neptune 4 Max

Neptune and Obico

I have been using the Neptune 4 Max for a little over a month now. Love the printer, but it can misbehave. I have been printing for a few years now and I can count on one hand how many spaghetti monsters I have printed. That number has already been dwarfed with the addition of my N4M. While doing some research on why and how to stop it I came across the Spaghetti Detective (renamed Obico). I have heard of this many years ago and just never had a use for it, plus it costs money. I did a little more looking this time and found out you can self-host the platform to use the detective. No more paying for it. I like free. I should note that Obico does have a free tier, but it only provides 10hours of AI crunching detection.

Here’s how I installed Obico/Spaghetti Detective on my Neptune 4 Max. You should be able to follow Obico’s installation instructions and just adjusting the file paths but just in case I wrote up how I did it. I have a small Linux server (an Intel NUC) that sits in my office and runs all of my goodies. Anything that needs to run 24/7 or be accessible at all times lives there. Unfortunately while a Raspberry Pi is great for most things Obico states that they do not have enough power to run the AI software. A more robust piece of hardware is required, any old computer or laptop should work. They did just release the Pi5 so I am curious if that would work. If the machine has an NVIDIA card in it even better.

Obico released a small guide to get you started with Obico and the Neptune 4 Max with the cloud. These directions will get your printer setup for Obico. There are similar instructions below on how I did it for the self-hosted version of Obico.

Elegoo Neptune 4 Max

Elegoo Neptune 4 Max

(UPDATED)

Let me start all of this with I am not an engineer nor an expert at 3D printing. This is all just shit that I have picked up over the years, read about or came across. I just want to spread some information and maybe help someone. Try the following at your own risk, I am not responsible for what you do. Don’t believe everything you read on the internet.

 

Intro

A month or so ago I upgraded my trusty old Monoprice Maker Select v2.1 to a Elegoo Neptune 4 Max. Wow. I’ve been printing non stop. This thing is a beast! Its freaking huge and it prints fast! My Monoprice is still going strong, and I actually gifted it to my son-in-law, but I needed a bigger build platform and I wanted speed. It was down to an Anycubic Kobra 2 Max or the Elegoo Neptune 4 Max. If you do your research you will find tons of posts of people that got the N4M and hated it, to return it and get the Kobra 2 Max. With just as many people who did the opposite and ended up sending the Kobra 2 Max back to get a Neptune 4 Max. I was sold on the fact that it runs Klipper. It may be an Elegoo version of Klipper but it is Klipper. There are people working on OpenNept4une, a firmware replacement for Elegoo’s Klipper. I have also heard that someone is working on a pure Debian version of community Klipper. That would be fantastic. Unfortunately this requires buying a USB to eMMC adapter to flash the machine which I don’t have. I have not done this yet and I am not sure if I will. But it is an option. You can find more information on the Elegoo Discord. Some are also upgrading the main board to something like a BTT Manta and Pi TFT50. One of the things I’ve heard when playing with the alternate firmware(s) is you may lose the functionality of the touchscreen, no bueno.

If you are new to printing or this is your first don’t expect a nice fat user manual or handbook to walk you through. You are going to have to survive off a collection of online help. Don’t expect to get a ton of super helpful customer support from a company in China like Elegoo. You are much better off on their Discord or in a Facebook group, and websites.

Even with my knowledge of the past few years it took me almost two full rolls of filament to get it dialed in. But now it prints beautifully every time, and fast. So expect to be tweaking your profile for a bit and doing lots of bed leveling and printing lots of first layer sheets and benchys along with XYZCubes. Run the tests, it helps.

The following is a mash up of some tips I have tried and figured out, or I have read about and found online.

Some of these steps may seem tedious or you just don’t want to do them, but it will save you time, headache, and filament – which is money. When I first started out for the longest time I never wanted to “waste” time with the calibration prints. Trust me you waste more time by not doing them. Orca makes it easy now anyway.

Philips Hue Alexa Naming Scheme

Philips Hue Alexa Naming Scheme

Yes, how you name your Philips Hue lights is highly important when you are connecting them to a Smart Assistant (with voice commands). Get things wrong and you end up with your Amazon Echo constantly spouting off “I’m sorry the Master Bedroom doesn’t support that.” You could also get plagued with your devices randomly becoming unresponsive with Alexa. Oh fun. Nothing to piss you off more than your lights just not working. I know first world problems right?

If you are just using the Hue app with no voice assistant you can get away with naming them whatever you want because it doesn’t really matter. When the voice commands are added the names of the rooms or groups you have them in as well as the names of the individual lights matter greatly. Not only will your smart assistant constantly just not fucking work with your lights, you may also get tired saying a particular phrase for a light or it may turn out you never actually called that light that name to begin with. Spend some time thinking about light names, seriously.

In my previous home I had a shit ton of Hue lights. When you have that many lights they end up becoming numbered. “Master Bedroom One,” “Living Room 3,” etc. Then when you have the rooms/groups of “Master Bedroom” or “Office” the lights with numbers in their names wont ever conflict with each other and their groups/rooms. Now that I am solo and in an apartment I only have a small handful of lights so I don’t need to number them anymore. Now I was getting conflicts with my names.

With my most recent struggles I have noticed, and eventually found the cure with the problem and the names I had chosen. I thought I picked them simply and perfectly because I honestly do not have that many lights in my apartment. As is turns out the biggest thing that was causing constant strife with my Echos and lights was the names I had chosen for the Echos themselves, along with the same conflicting name for the rooms they are in. For example, I have an Echo Dot in my master bedroom which I had named simply “Master Bedroom” because I was only thinking of my Echos at the time and not in conjunction with the light names; “Master Bedroom,” “Office,” and “Kitchen.” Well I had also made some rooms with the Hue app with the same names of “Master Bedroom,” “Office” and “Kitchen.” Same names as the Echo names, damn it. The lights worked initially when I set them up but after a few houros or day or so they all stopped and my Alexa started rebelling.

 

The Simple Fix

So there is a simple fix, which took me hours to figure out in the middle of the night I hate to admit. I ended up renaming the Echos first. “Master Bedroom Echo,” “Office Echo,” and “Kitchen Echo” to separate them from the name of the groups/rooms for the lights. I also figured out that I was getting multiple devices with the same names in my Alexa app because of the scheme I had originally chosen. So I removed all groups and rooms from the Hue app. I don’t use the Hue app much as it is, primarily just the Echos with the lights or Apple Homekit. So my Hue app has just one group now called “All Hue Lights” so they are easy to get to in the Hue app if I ever need to use it. Then in the Amazon Alexa app I did a device discovery and it pulled the one group and all the lights and Echos. Then in the Echo app I created the groups of “Master Bedroom,” “Office” and “Kitchen.” No more conflicts now, the lights all work and no more unresponsive remarks from Alexa or the apps.

Finally the shit works.
