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.

Monitor your security system with a RPi

I had programmed a page of goodness in Node-Red for being the middle-man between the internet and my security system. Here’s the schpeal…

I used to work for an alarm company for a number of years. It’s a job that has kind of stuck with me, specially all the shit and skills that I learned while doing it. So I still have friends in the industry and I still have equipment from when I worked there. Naturally I install my own security system. Not wanting to pay for monitoring but still wanting to be notified with issues gave me a problem. I happen to know Pies so I decided to use a Raspberry Pi with Node-Red to solve that problem.

There are many ways to get notifications from your security system these days but they all require some kind of monitoring or to be activated by an alarm company (someone with a license). Using the Raspberry Pi I could do everything I wanted to. Node-Red just made it that much easier.

I programmed all of this via NR on one of my Raspberry Pies. I believe at the time I was programming in Node-Red v0.12 (around May 2016 I think). Here’s the flow:

I cannot be held responsible for anything bad that may happen. This has been coded to the best of my ability but there may be bugs and some of it may be unfinished. USE AT YOUR OWN RISK!
