Hello all,
I’ve had at least 4 filament jam on the AMS lite hub. And they always look like this:
The filament is jamming on the AMS lite preventing it to get pulled properly from the hotend. Why is this happenning? It seems to be more frequent with matte PLA (although it happened with galaxy PLA also). Maybe the extruder motor is too hot and the heat are smoothing the filament just under the AMS hub and then creating this jam when pushing? Or maybe too resistance from the bowden tubes? It does not seem to be heatcreep as the jam happens way above the cold end.
The color change process have two motors that work to move the filament. The extruder gears retract the filament from the hotend, then when it’s cut, the ams motor pull back the filament. I think the jam happens on the first phase.
PS: I am using the long retraction option but I am pretty sure that already happened before I turned this on.
