By niamor2June 20, in Improve your 3D prints. I'e got a serious problem with my last print with PVA on my Ultimaker 3 : the material stopped extruding after 1hr, and while trying to unload the PVA filament I realized it was stuck in the feeder. Then I removed the bowden tube at both ends, removed the PVA filament from the printhead, and cut the filament under the feeder.
But I still couldn't remove the filament, whatever side I pulled on :. I guess that feeder problem ultimaker 3 free download be caused by a degradation of the filament by ambient humidity : the spool was left out in the open air for more than one month.
But I still don't know how to remove the filament from the feeder. May be I could try moistening the filament in the feeder to soften it and remove it more easily? Or will I have to disassemble the feeder completely? Any ideas? Did you squeeze the lever on the feeder? Lift that lever up by squeezing with some fingers on the top of the finger and some on that lever. Also consider printing wedgebot asap:.
Yes I tried but it didn't change anything. Squeezing the lever or not, thye feeder problem ultimaker 3 free download remains stuck I can see that your feeder is really tight and that is the cause of the ground up filaments. Loosen it up a bit. Turn the screw so the marker is at the top. Get a nylon paint brush and vacuum cleaner.
Remove the bowden tube. Then try to dislodge the ground filament while sucking them out. If that fails, try this Thanks for the advice, but I already removed the bowden tube, and I couldn't remove the filament no matter feeder problem ultimaker 3 free download.
So I tried your last solution, and here is what I found :. I don't understand how that could happen, but it seems the filament folded inside the feeder So I finally extracted feeder problem ultimaker 3 free download filament successfully, and launched a print with a new PVA spool : everything seems to work properly!
PVA and Nylon need to be kept quite dry. Especially nylon. I don't leave my PVA on the printer overnight if it's not printing. I keep it in a sealed bag. Whenever I get new filament with new dessicant I move the dessicant packet to my nylon and pva bags as the PLA really doesn't need it. You can tell if PVA is too wet or any material because it sizzles and pops while printing and comes out more snowy than clear lots of micro steam bubbles. You can put it on a heated bed at 60C with a towel over it for 10 or 20 hours.
I suspect that will work. Assuming that's the problem. PVA is annoying in that if it gets too dry it also fails gets brittle. I'm not sure this math is the correct way to calculate things for drying filament but it's what I use.
That should be safe I would hope. It just might take many hours for the water to escape the pva - especially on the inner turns of filament deep in the spool. Anyway I've used this trick heat it to C for nylon to dry nylon to great success. Thanks a lot! For now I will try putting the spool in feeder problem ultimaker 3 free download airtight pouch with dessicant for several days.
If that doesn't work I will try the heated bed. I would try the heated bed, then put into sealed bed with desiccant. If there is a lot of moisture in the PVA, it could take a while to get from the core to the edges. Also, it could be enough to overwhelm the desiccant.

I better vacuum seal my remaining PVA filament then.

Hello guys, you always trouble with my problems, but unfortunately it is only recently that I use the 3D printer. I post these photos to figure out feeder problem ultimaker 3 free download to fix it. Another thing, when I have to replace the print core 2, often the machine says "contact ultimaker temperature error". You can receive an error message if you take the Core out when the printer isn't expecting you to. Where are you at on the printer menu when you remove the Core?
It looks like your filament is stopping extruding. What settings are you using? Is there any chance your filament is getting tangled? When I remove the print Core 2 I do it when the machine tells me to open the door and remove the print core.
It seems to me a little bit as the second print core is not your only problem. Check if you can move any of the x and the y rods. If so, untighten one pulley of that rod feeder problem ultimaker 3 free download tighten it again so the rod does not move anymore. You may want to look how close to the edge the belts are running over the two pulleys in question and then decide which to move.
I see a lot of stringing. Is that your problem? Or is it the shifted layers at the side of your print? If you have altered settings, use "discard all changes" in the quality profiles dropdownbox to go to default settings. Regarding changing cores - I believe you have to wait until the temperature is below a certain temperature 40C?
Also where the fan stops before changing cores if you don't want that error message but if you get it don't worry - just power cycle the printer.
Regarding the layer shifting feeder problem ultimaker 3 free download that means you have play somewhere. It happens when the pattern of the print changes which implies it is printing clockwise versus clockwise at those same locations and the play looseness aka backlash is causing these layers to stick out. Or in. I'd start by checking for loose things in your gantry to see what is loose. Check the 4 sliding blocks for cracks.
Check for nozzle being loose or other parts being loose. Push it in all 4 directions. Does it move around? Also look at the belts - they should auto-tighten but maybe one is loose? It has to be VERY loose to see the kind of play you see. Like floppy loose.
There is a very small chance it is a temperature issue - if the nozzle is oscillating slowly in temperature by more than 5C you can also get this pattern because hotter nozzles extrude more.
This is easy to test during the print - just feeder problem ultimaker 3 free download the nozzle temperature readings from the TUNE menu while it's printing. This is unlikely because your part looks too large for an oscillation to be that slow. Good morning. Thank you all for the advice. As soon as I can do the tests you have advised me and let me know how it went. Do you advise me to use the Ultimaker materials because the machine is set to just go with your own? The combination of Cura feeder problem ultimaker 3 free download all the quality profiles and the UM3 and the Ultimaker materials is thoroughly tested.
You will get excellent results in terms of print quality and reliability. Ultimaker sells an open system, and you can choose to use other filaments. No problem with me, but often that means you have feeder problem ultimaker 3 free download spend time on optimising print settings and dealing with failed prints, because materials from different suppliers have different properties. I agree with tom nagel but I usually buy filaments from other suppliers.
I really like colorfabb ngen so far have only printed maybe 10 meters and 10 prints. Don't get cheap chinese filaments unless you care more about functionality than how it looks and don't care about strength, brittleness. Hi friend. I checked the straps, one was slightly slow. I tried to pull it, it works, but then you loose the belt of the opposite feeder problem ultimaker 3 free download.
So I don't understand where I'm wrong. I don't think you need to tighten the straps. You just need to tighten the pulleys. The pulleys are not supposed to rotate on their shafts - they are supposed to be attached to the shaft.
There is a small screw to connect them together. If that screw isn't tight enough then the pulley slips a tiny amount and can cause "layer shifting". I'm feeder problem ultimaker 3 free download sure that you even have layer shifting. There is no photo above that shows layer shifting.
It usually looks like this. Actually I should have you just read this:. You need to be a member in order to leave a comment. Sign up for a new account in our community. It's easy!

Dim3nsioneer Posted January 4, Col PLA, comunque, ho problemi anche io. Spero di averti dato qualche idea. Sorry, I don't really understand that Feeder problem ultimaker 3 free download should do.
I very much like to help you, but I don't understand what your main problem is. Try to describe your problem please. VapeLounge 0 Posted January 5, Print quality should then be very good. If you have done the above, maybe a video will help in judging what is wrong.
