The Prusa CORE One is a really interesting 3D printer that provides the person full freedom and lots of fashionable options. But it surely doesn’t have the Prusa XL’s a number of toolheads. As an alternative, CORE One house owners have to depend on an MMU in the event that they need to work with multiple filament roll robotically. Sadly, the present MMU3 generally is a little bit of a ache and leaves quite a bit to be desired. To resolve its points, Voxel3D designed the COREBOXX filament administration system. Even higher, they simply upgraded it with good humidity management.
The truth that that is even attainable is a testomony to Prusa’s dedication to person freedom — one thing that’s turning into much less and fewer widespread within the shopper 3D printer business. Prusa is so devoted to that philosophy that they gave the CORE One a “GPIO hackerboard,” which acts as a direct hyperlink between the printer’s management board and no matter different {hardware} the person desires to connect. That’s essential to the performance of the COREBOXX and its capability to deal with humidity.
Earlier than we dive into that functionality, which was the subject of Voxel3D’s most up-to-date video, it’s best to know that the COREBOXX is a filament administration system that reconfigures the MMU3, with design inspiration from open-source group tasks just like the “Filamentalist” rewinder for the ERCF (Enraged Rabbit Carrot Feeder) v2, which is standard amongst Voron builders. COREBOXX does quite a bit to make the MMU3 person expertise extra nice, however one of many key options is that rewinder system that eliminates the MMU3’s troublesome filament buffer association.
Voxel3D designed the COREBOXX particularly for the Prusa CORE One and there’s a entire video about it, for these of you who need to know extra.
However Voxel3D’s latest video is about filament drying and the COREBOXX’s system for dealing with that. Moist filament is unhealthy and dry filament is sweet. Voxel3D designed COREBOXX to make use of desiccant, a heater, and a fan for drying and their customized controller lets the CORE One handle these. It interfaces via the GPIO hackerboard that we talked about earlier, which permits for a seamless setup.
That customized controller known as the “Semi-smart” and it connects to the GPIO hackerboard. The controller hosts an Arduino Nano R3 growth board and has connections for the MMU (out and in), a person interface (with buttons and OLED display screen), an LED strip, a thermistor, a PTC heater, followers, and a servo. Within the COREBOXX and paired with a CORE One, it supplies management over the entire drying features and works along with the MMU.
COREBOXX and Semi-smart are open-source and you may construct them utilizing the offered information with out shopping for something from Voxel3D. However if you wish to make issues simpler on your self and sure get monetary savings in comparison with self-sourcing parts, there are kits obtainable for each via Blurolls.
