filament under extrusion?

Hi! I recently had a nozzle clog that the atomic pull didn't quick work on--I disassembled the nozzle and removed my clogging problem.

After reassembling my nozzle--I was only able to 2 print out two items and all of the subsequent prints have failed.

I cleaned out my nozzle again using the Atomic pull method, and when I load in filament it extrudes out. However when I try to print--the filament doesn't seem to come out fast enough and bunches up at the nozzle head--as shown in the photo below.

I've tried cleaning out my nozzle again using the atomic pull method, and have also tried leveling my build plate again--still have the same trouble.

When it was failing to print--it would only start the print a few layers then the filament would stop loading--now it seems like there's no filament loading at all or it seems to load or extrude too slowly.

Also, when I had the nozzle apart a second time--I did get a heater has stopped error message.

Any pointers on where to start with my trouble shooting would be super helpful. Thanks for helping me troubleshoot this!

    There are a few issues that can cause things like this.

    How Many hours has your printer printed? the PTFE coupler can deform and not allow the filament to flow properly.

    It can be a nozzle clog that needs a few atomic pulls to clear or you may need to push a fine wire up the center of the nozzle when its hot and rub around the inside edge.

    Could be the feeder tension isn't enough and is slipping.

    and lots of other things that I cant remember right now.

    You can try removing the bowden tube from the top of the hot end and pushing some filament through by hand. see if there is much restriction there. if ok, look at how deep the imprint from the feeder is on the filament. if there are light marks the you can increase the feeder tension.

    Thanks! I reassembled the nozzle again--this time making sure that the PTFE coupler was within 1mm to the isolator Nut and I'm back up and printing :)

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
