The tool is a micro computer called Raspberry pi. Its not the dessert but its still a pretty sweet treat that is worth looking into.
The Pi itself can be programmed to do numerous things but today the focus is on the Octoprint program.
Full disclosure I am no expert, nor do I claim to be. I just added this to my Cr-10s this week.
Why I was convinced to buy it.
> Control the 3d printer when you are away from home
> The ability to stop prints while away from home
> the ability to upload & start prints while away from home!!!
There's more but basically I liked the idea of all the not being at home features.
There is even a setting to detect failing prints (spaghetti monsters) when they start to occur AND can target that section to be skipped! Potentially saving a 22hr print that is 19hrs in and starts to fail.
Why I like it,
Its a new skill to learn and develop that has many rewards.
So far with the Raspberry pi I experienced the ultimate sweetness of controlling my 3d printer entirely from my phone! Moving the bed, changing nozzle heights and bed temperatures.
If you notice in the bottom left picture my set up is awkward. My control box is on the floor in a hard to reach spot. The Pi is a huge help and I can use my printer with out noticing this inconvenience.
The ability to add
> Touch screens, a upgrade that looks and feels nice.
> Cameras, for recording or pictures
> temperature & humidity sensors
> more Octoprint features and other operating systems with more options.
With youtube and online support
chatrooms anyone can learn it!
What I don't like,
Troubleshooting is necessary, all the steps may not work for you and you will need to research work arounds.
For example, once the raspberry pi is connected to the internet. You will have to open a website called octopi.local which doesn't load 100% of the time. So you can't connect.. but with a screen added to the Pi you can login with
It will the load new information and possibly reveal its IP address.
I say possibly because this doesn't work 100% either but when it does type the IP address in the bar you would type a website address in. ( I delete the image and reinstall to override some times to get it going).
There are hiccups here and there but people and guides are everywhere to help.
So its a great tool to add to help you create!
I printed the case for the Raspberry pi so you can't see it but its a 3b+.
