Does anyone know what tells the feeder to stop feeding when the filament reaches the printhead, when you’re loading a fresh filament?
Currently, mine is continuing to try feeding filament once it reaches the head, & I can’t figure out why.
As best I can figure the “load filament” macro runs the pusher until the runout sensor in the tool head switches true.
If I’m right and the feed tube breaks or comes out of a fitting it COULD push the entire roll onto the floor. OR if the switch doesn’t trigger run until it grinds thru the filament and keep on running.

So there’s a runout sensor in the printhead too?
No, there is not a sensor in the toolhead. The toolhead is the same as the Zero.
Maybe this can help you out.

Cheers. I’ve had a read through that. Nothing mentioned in that article seems to be an issue. The feeder works fine in general. It’s merely when loading, it’s as if it’s trying to feed filament for several seconds more than it needs to. Currently I depress the gear lever on the feeder once the filament reaches the extruder, until it stops feeding. Be nice if I could find out how to get it behaving again though.
Still not figured out the issue as yet, but I haved used it as an excuse to print & fit this enclosure file I downloaded, today. Figured that’d allow me to check & monitor all the mechanism in operation, & with the added benefit of making it easy to vacuum out any filament dust/shreds which may accumulate in there.

Found out why it’s trying to continue feeding when it reaches the printhead. With me slowing the feeder down in the config, it wasn’t tripping whichever sensor detects stoppage. I’ve upped the speed to ⅔ of the default speed, & that appears to be enough to get it behaving as it ought.
