Yes it’s a Pi b3+ running the latest Octoprint. My first print with it. Great inexpensive addon for the benefits. The Pi Cam leaves a little to be desired. Probably upgrade that soon.
I can sit inside and monitor it out in my tiny shop. I have the Spaghetti app running. If it detects a print fail it shuts down.
I added a fan and thermal switch to the extruder motor, it gets to about 170f normal operation. Now, never above 90f and it’s auto on/off.
There are a couple of laser cutter mods out there. I might try that in the future. They start at about $300 us.
I will use the Pi to monitor another thermal switch in case of runaway heat/ print fail. There is a Pi plugin for that.
I am also toying with adding/developing a fire extinguisher mod so I can print unattended and not worry about leaving the premises.
A good solid bench is a must for the printer. Building it from a kit is also a must. You gain knowledge you will need later for maintenance.
Now I just need a bigger printer! One that prints metals too! I am going to have to rob a bank soon Hobbies suck! Suck you in, that is.
One last thing. I recommend getting a router that is made with iOT in mind. I have many iOT “things”. Keep your networks separate.
