This prompt appears during the printing process when CFS filament is in use. If you need to switch to printing from an external spool holder, you must first unload the current CFS filament. Specific situations include:
When initiating a print, the CFS option is not selected, but CFS filament is still present in the extruder.
Manual unloading: Before printing, users need to manually click unload to ensure the CFS filament is completely removed.
Load external spool holder filament: After unloading is complete, you can load the filament from the external spool holder.
Reinitiate printing: After confirming the external spool holder filament is installed, start the print job again.
Click the "Retract" button on the screen to completely remove the CFS filament.
Confirm that the CFS filament has been successfully unloaded, check if any CFS filament remains in the extruder.
Load the external spool holder filament, ensuring a good connection.
Reinitiate the print job, making sure to select the external spool holder.
Click the "Retract" button on the screen to completely remove the CFS filament.
Confirm that the CFS filament has been successfully unloaded, check if any CFS filament remains in the extruder.
Load the external spool holder filament, ensuring a good connection.
