Giano, first of all, is a remix of the existing Rome project. We just managed to integrate it into the Voron StealthBurner tolhead and simplified for the specific Voron use
Giano is MUCH faster then any regular MMU or ERCF setup. The whole filament unloading and loading process is multiple times faster, not only because Giano just has to park the filament behind the y-junction. In its native mode, Giano handles the loading and unloading process and skips the slicer controlled part of it. This process is highly optimized for a specific Hotend / Filament combination. No more configuration of cooling moves, skinnydip, ramming, ....
Giano is super simple:
- You can call
GIANO_HOMEto position the filaments near the toolheads not required - You can use
T0orGIANO_FILAMENT_1to select the first filament. - You can use
T1orGIANO_FILAMENT_2to select the second filament. - You can use
EJECT_TOOLIn the print end to unload the filament
No special slicer configuration a required, only classic MMU Setup.
No special start gcode or end gcode
In the file giano_bambu.cfg you can see the macro I use to avoid purge tower like in this video.
Thanks ERCF for the tip macr
