Ultimaker 2+ no filament extrusion during print

[AdamBoulton 0]

Hi, 

 

I am using an Ultimaker 2+ and have successfully completed around 20 prints. I have recently run into an issue whereby the filament won't extrude during print. I found the exact same issue on a video on Youtube but I don't know how it was solved:

 

 

Just before the print, the filament extrudes fine, but when it begins to print there is nothing. I am using Cura 4 & version 3.3.0 firmware and printing using an SD card.

 

Thank you in advance for any help / suggestions.

maybe the nozzle is too close.  Maybe the nozzle is too far from the glass.  Try pushing the glass up and down while it prints initially.  maybe the filament ground up too much at the feeder.  Push some filament through by hand while it's printing the bottom layer.

Hi, thanks for taking your time to reply. I had ended up doing several things, a factory reset, re-feed the filament, re-calibrate. I tried to then print after that but was still having the same issue. What ended up working was "forcing" the filament through using the Maintenance -> Advanced -> Move material. I fed quite a bit through so I knew it was flowing fine. I think you are correct, there was something causing a block or the filament was grinding so by feeding some of it through manually caused something to help it flow better.

 

Thanks again,
