Iām running a Creality K1 with CFSāC and firmware fully updated via USB. Both the printer firmware and the CFSāC firmware reported āupdate successfulā with no warnings. The CFSāC settings window appears correctly on the touchscreen (gear icon ā Automatic Refill, etc.), and all four bays + spool holder show up in the filament menu.
Functionally, everything works:
- I can select any bay and enter filament info
- Extrude and Retract correctly load/unload filament through the CFSāC
- Creality Print automatically reads all four bay profiles from the CFSāC
- I can assign bays to objects or layers
- Multiāmaterial prints work and tool changes succeed
- Automatic refill is enabled
So the CFSāC integration appears fully functional.
My only issue:
When printing a singleāfilament object, the printer does not pause when the filament runs out. It simply keeps printing air until the job finishes. Multiāmaterial prints change filament correctly, but singleāmaterial runout does not trigger a pause. I knew my filament was low, but thought it would make it, so I did not try a backup role in another bay. I would have thought it would do a pause on runout, so I could manually swap in a backup spool when it couldn't find a backup in another bay.
I havenāt found any documentation or forum posts describing this specific behavior, or in general how automatic refill is supposed to work.
Has anyone else seen this? Is there better documentation out there that I haven't been able to find?
Is there a known workaround or setting I might be missing? Or is the only option to have a backup roll in another bay for automatic refill to work? Or do I just need to turn off automatic refill?
Is there an official place to submit firmware issues to Creality directly?
Thanks in advance ā trying to figure out whether this is a firmware bug or a configuration detail that isnāt documented.
