it sounds like bed height likely caused the latter issue, can you set it to change filament, so the head heats up and you can just pull the filament out?

I heated up the extruder and tried that yes, unfortunately to no avail.
I thought so as well originally, but I’ve experimented with many different heights high and low, without success. I have also tried to use the change filament options to my advantage, but nothing I’ve done has led to success.
It sounds like you are going to have to take apart the head and investigate further inside, it may be that the gears have been jammed with melted plastic which has cooled and hardened. (just a theory) Good luck with it.
That’s what I’m thinking as well. Thanks for all of your help, I really appreciate it. I’m not sure how this happened, I may end up waiting for XYZ to get their act together and respond to me haha.
Hi Itopher, I sometimes get this problem as well.
Luckily, there is a solution to this problem! Firstly, if you try using plyers, then maybe you can force the filament out. Do not try too hard as you may damage your machine.
The other solution is to watch this video here: da Vinci Jr. 1.0 - Drive Gear Cleaning - YouTube 533
This video by XYZ shows you how to take apart your printer so you have access to the gears that are jammed. There you can manually remove the filament.
In the video, the guy removes the wires in the casing surrounding the gears, I do not advise it. Just keep them plugged in. He only does it so that he has more room to access the gears with. Just keep them attached since putting them back is really frustrating.
Good luck!
You sure you didn’t take the lock off the filament? Sometimes even popping the filament box off, and making sure it’s not tangled would help 2…
Be aware that this is a junior.
The gears are not in the head. The feeder and the nozzle are two seperate units far apart.
The filament feeder and nozzle are separated by a long filament guide tube.
Feeding gears and hot unit are thus separated by about 40 cm.
Most problems with grinding feeder wheel are caused by a blockage in the nozzle unit.
Because of the blockage the feeder cannot push the filament into the tube and starts clicking and grinding.
Yes, if a Jr. then the head can be easily removed and if you are capable, disassembled to clean and check. I’ve not had one apart, but clearly there is filament stuck in the path or in the hot end section, and clearing this may be a challenge. Take it slow and try to see where the actual sticking place is. It might be necessary to get a new head but most blockages can be cleared - the main thing is to not damage the extruder in the process.
Yes, this is the best approach outside of a complete extruder head disassembly.
Hello Chris,
I have had the same issue with my Junior.
the filament is stuck in the nozzle.
The solution is simple but requires some hands on work.
1) removing the head
Cut the fillament below the feeder.
Take of the printing head from the carriage (push white button on top to release)
Remove fillament guiding tube from feeder and pint head
you might have to push the filament through the feeder (while pushing the filament release) before you can take off the tube.
Now you should have a loose printing head with about 40 cm of filament sticking out.
just put it down on the bed but leave the electronic flat cable on
2) removing stuck filament
Start the nozzle cleaning cycle via the operating menu.
utilities>clean nozzle
When the temerature is ok, poke the nozzle with the cleaning needle
stop the cleaning cycle by pushing ok
the filament is probably still stuck.
now go to monitor mode in the menu.
When temperature drops to about 100 degrees celsius start pulling hard on the filament while you hold on tight to the printing head.
Now the filament should come out.
3) prevention
by deep cleaning the nozzle on regular basis this can be prevented.
yes completely agree with approach. I have done the same with my Da Vinci 2.0. I recommend cleaning the drive gears on the extruder at regular intervals. I usually give a quick clean before a large print just to ensure I don’t have any issues.
Good luck,
Jay

Try popping the extruder assembly back into place.
