Core One with MMU3 issue with Join Sppol
So this weekend I thought I would try the Join Spool to try and use up some leftover filament. I put the small amount of filament on tool 1, and then did a Join Spool on Tool 4. When the Tool 1 finished and the filament was all used up and was just past the FINDA going toward the hot end, I just gave me this one error and I could not get not get out of this loop so I had to cancel the entire print job. Anybody have any ideas. I am not sure what is supposed to happen at this point? Is the MMU supposed to grab the next filament and push it behind the small amount of filament left in the tube or is the MMU supposed to grab the little piece of filament and push it back to the buffer and then continue on Tool 4. Any help is appreciated. Thank you.

You first need to remove any remaining filament that is still in the MMU from the empty spool, you can easily remove this from the front of the MMU

Richard, Thank you. So is the Join Spool supposed to be a manual process where the user has physically remove the last remnant of filament? I was thinking that it would automatically change over to the other spool. Tool 1 was empty, nothing from the MMU to the buffer. The only remain filament was from the MMU to Extruder. As soon as the filament was pulled past the FINDA sensor it gave the error. Seems like for the this to work correctly one other filament sensor would be needed before the FINDA Sensor, so that it would know that the filament was out and that it needed to retract the remaining filament back into the buffer and then continue to the next spool, in this case 4. Thank you for all the help.

You'd think it should be automatic, but I don't know how that works. The only thing I've experienced so far is that a spool runs out and you then have to load a new one.
