The BentoBox is designed to filter out some of the VOCs generated when printing certain materials. It wants two 40mm fans, a HEPA filter, and activated acid-free charcoal (it is claimed that acidful charcoal will fuck up your printer; I don't know anything about it). I had several Delta 40mm screamers free I'd pulled from an [[Aruba_2500-48p|Aruba switch]] ([[Noctua]] NF-A4s are <b>not</b> strong enough to effectively draw air through the tower, sadly). I tapped into the AMS's 24V circuit using a [https://www.etsy.com/listing/1460463476/bambu-power-tap-v13-kit Power Tap v1.3] (see below). The fans are 12V, so I employed a LMS2596 buck converter to efficiently drop the voltage. The BentoBox only serves to draw air through the filter and charcoal; it doesn't vent to the outside or anything. I'll be changing up the power source for this stack; see below. | The BentoBox is designed to filter out some of the VOCs generated when printing certain materials.

The Power Tap Kit accepts a 6-pin AMS cable, and bridges it to a 6-pin AMS output plus a 24V female barreljack. This allows you to easily break out the 24V line for external power consumption. You could just cut the AMS cable, add two splitters, and solder/hotwrap everything back together, but this is a nice, clean PCB in an attractive box, for $9. | The Power Tap Kit accepts a 6-pin AMS cable, and bridges it to a 6-pin AMS output plus a 24V female barreljack.

The AC adapter theoretically offers 120W, but it's safer to assume no more than 90W (¾ of the rated output). This will be used to drive our heating elements and fans. The Arduino itself is powered off the AMS circuit. Leaving aside peripherals, it ought not draw more than 125 mA, even when transmitting on wireless. This ought be safe, and is less than our fans were previously drawing from the AMS. Remember, Bambu doesn't guarantee any slack on the AMS circuit, and expressly instructs you not to draw from it. | |||
The temperature switch is a final guard against a failure in power control; it will open (disabling the heater) at 60C, the maximum temperature we want in the chamber.

These filament associations are encoded in the firmware. The filament being printed is acquired from the Bambu's MQTT.

We use pin D2 for the fan tachometer, employing a hardware interrupt. We use pin D3 for the 25KHz fan PWM, employing hardware PWM. The DS18B20 is read on D4. The relay is controlled via D5. D14 (SDA) and D15 (SCL) control the CCS811 using I2C. | |||
