Hi @michaelc1011, really sorry to hear this happened. Pings can drop for a number of reasons:
- Poor splices can affect extrusion. If a splice is thin or necking, it will have trouble being gripped by the extruder. If a splice is thicker or bulging (>1.8mm), it can get caught somewhere along the filament path in Palette or have a harder time driving through the printer’s extruder. Both can cause the pings to drop. To troubleshoot splices, you can read more about how to fix this with splice tuning.
- A clog or some sort of obstruction from the extruder to the hot end.
- Filament breakage inside Palette, or unable to feed filament from one of the inputs. If you noticed there was no filament inside Palette just passed the splice core or near the outgoing drive, it’s possible the filament broke there and the printer used up the remaining filament but no further splices occurred.
These are some different reasons why this could happen. If you observe it happen again, please take a photo of the Palette unit without it’s top cover, and observe where filament is from the Palette to the extruder.
