Printing direct from USS Drybox on Core One+
Running the Prusa USS Drybox on my Core One+ and wanted to share early experience plus two open questions.
The box has an opening that fits either the bare filament or a PTFE tube. I tried printing with the filament sticking out directly (no tube) on a 5h print — worked perfectly, and the internal humidity sensor read 10% both before and after. I'm wondering if I actually need to use a PTFE tube for this connection or can I just use it as it is. The filament touches the drybox and bends a bit in its route to the printer. I thought it would be a problem but it seems to work fine (with PLA):
My big problem is unloading. The Core One has a long filament buffer from the filament entrance to the extruder, so there's a lot of buffer to pull out when unloading filament. Since the spool sits inside the sealed box, I can't rewind the slack back onto the roll, so I'm left with a long length of filament hanging out with nowhere to go (photo below). What's the best way to deal with this?
I haven't printed the official PTFE tube solution yet — but as far as I can tell it only protects the filament from being exposed to humidity during feeding and doesn't help the unloading problem. Am I missing something, or is there a trick to this?
RE: Printing direct from USS Drybox on Core One+
I think the "official solution" is to open one of the side flaps, put your finger in there, and wind the filament back onto the spool.
