9.9.1 Recommended Procedure: “Hot Swap”
This procedure avoids pausing the printer entirely.
Locate and prep your new spool of material (trim end clean, make sure there are no tangles, etc).
On the old spool, cut the filament about 6 inches in front of the extruder.
Remove the old spool from the printer. Install the new spool into the filament bay.
If you’re impatient, you can now trim the tail of the filament in the extruder shorter. Or you can wait for the
printer to consume the 6 inch tail you cut originally. Make the cut square with the filament – do not angle the cut
like normal.
