(Un)Official Prusa Enclosure "Smart Box" - Project  

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Short update: Found this awseome mod and started to integrate it already!

So besides auto air filtration, i now can also set a target temp based on the flap and heater from the mod!

I also started to move away from the bread board to a hand made pcb, here are some pics:

New Case, LCD, controlls and ESP32

Custom / hand made PCB 

AC / Traget temp control

Lid / Flap test

After seeing those wires connecting to board - that's wayyyyyyy above my pay grade. 😱 😱 

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

You can do a lot of this with OctoPrint and the existing plugins for it, which might be a little less daunting than assembling prototype boards and building everything from scratch. I myself only use a plugin to control LEDs in the enclosure and to switch the power for everything off when the printer is idle. And I use the Pi camera with OctoPrint of course. But I know there is an enclosure plugin and you can control stuff via the GPIO pins of the RasPi. Integrating temp sensors and controlling some servos and fans into my setup on the Pi is on my todo list for this winter.

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

This is pretty cool. I had ideas to do much the same, though I am (currently) less interested in VOC and particulates. I have a strip of RGBW LEDs and I was thinking of testing those out this weekend with the intention of integrating them soon. I am getting tired of using a flashlight when I want to inspect a print in-progress.

I have some other unrelated microcontroller projects too that I want to wrap up, and spent today learning how to use git and GitHub for code version control and platform independent coding. So I'm all set for another project now... 🤣

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Any chance to get the source code?

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

I will share the source code as soon as I can here, it's just a few hundred lines of yaml for esphome. Only a few a lambdas / c code. 

Works without wlan, home assistant but could be enhanced to be monitored and controlled from home assistant as well (or via mqtt). 

And yes, I would not recommend this as your first esphome / esp32 project as it requires a lot of soldering 😂

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Made some progress and the inputs and sensors are now done and not as messy as before!

Need to add the output board with 3 Mosfets (light, fan, air filter), 2 Relais(Heater, Printer Power), and the Servo (Flap) + Buck Converter and AC stuff.

Here is the current esphome source (WIP!)

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Updated POM:

1 * ESP32

1 * Sen54 Sensor

1 * Rotary Encoder

3 * Switches (Retro!)

1 * LCD ST7735

1 * IO Expander (MCP23017, overkill but i had it at home)

3 * Dual MOSFET Switch Module - Control 24v Leds, AirFilter, Fan via esp32

1 * Buck Converter (24v to 5v)

2 * 3.3V Relais (Heater and to control Printer power)

From Automated Heating System

1 * 200W heater+fan combo (i use a MOSFET to control the fan)

1* SG-90 type servo

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Thanks!

Maybe you should put it all into a git repo?

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

I will post the code and everything to github / printables when I am done.

Here are some updates:

Added DS18B20 temperature probe for the heater (as in the Automated Heating System)

Created power/breakout board and a case for it + PSU mount with power switch and plug

The case and PSU will be mounted to the back like in the Automated Heating System, case is a bit bigger 😉

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Finally up and running, more details soon, here are some pics:

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

I just got my enclosure built yesterday and was immediately looking for something like this. Especially since I’m using the HEPA filter and the LED lighting. I absolutely love this! Especially tying it together with the heater automation as I was very interested in that as well. I’m able to get the inside up to 35C but it takes 3 hours of printing. Obviously not ideal for ABS / Nylon. Have you had any more updates to this project? Do you need help with anything? I’d love to help if you need it!

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Hi all, 

It been a while, in the meantime I finished the build and already using it!

I added an additional temp sensor and also a runtime counter for the airfilter + a nevermore v6 to speed up the filtration.

I want to add a timer for the heater or couple it somehow with the printer, so that it stops heating If the print is finished.

Heater and filter is great! 

Fun fact, when heating starts, VOC is going up only from the heater! Otherwise I can see that, based on the material there is quite some pm1/2 and or VOC, and my automation autostarts the airfilter and stops when below a treshhold.

I started to work on more documentation (fitzing diagram,...) but I guess I need the Christmas vacation to finish it and upload it to github. 

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Looking forward to it! 👍 

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Here you can see a heating for abs with heater on and heatbed at 100c, took 25min to heat up. 

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

First print was a short one, 2nd was longer, so I turned off the heater and went to bed, you can see that the heat from the bed keeps heating up the enclosure 😉 

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

I finished the first shot of the fritzing sketch, took longer than building it 😉 

RE: (Un)Official Prusa Enclosure "Smart Box" - Project

Great project, Thomas.  I'm waiting for my new Mk4 w/Enclosure kit to arrive after Christmas, and I'm excited to see how this progresses -- I'll certainly attempt a make!
