This is what happens when you stop printing everyday, things get stuck and fixing them just makes things worse. I tried to get NinjaFlex to print, the extruder kept getting jammed, I tried cleaning filament, and it didn't go through. Ended up taking the whole head apart cleaning it (including replac...

Found the nozzle page under Upgrades. Seems weird that V4 is still considered an upgrade given that this is the standard hotend for a year or more...

I clogged two of them and don't have spares now. Where can buy spare ones? I found nozzles for V3 hotends on the MakerGear site but not for V4.

I am using PETG (love that stuff) and it seems to clog the nozzle once in a while.

Thanks

I am printing another drive (using the extruder that does work). So updates only after the print (and dinner). Printing a new filament drive proved to be useless -- I printed in PTEG and filament path was too narrow... I did revisit the original drive, and this time cleaned the path with a 2mm dril...

I am printing another drive (using the extruder that does work). So updates only after the print (and dinner).

Thanks again Jules, Tim, and Insta for the suggestions.

Maybe. Since it's a V4, you should be able to see the filament come out the bottom of the drive and go into the top of the hot-end. Is it getting that far? The most common place to get stuck is going into the hot-end, if the filament drive is out of alignment with the hot-end. If it's stuck in the ...

Tim, thanks for the reply. Indeed the initial problem started when the print got into long straight lines. I was planning to printing again with slower speed. However, since then I replaced the whole head (hotend) and still cannot solve my problems. The new head did not get to print anything, it fa...

Reduce the tension on the Filament Drive Screw. (Better yet, back the filament out and check the tooth marks. The bite needs to be under 15%.) http://forum.makergear.com/viewtopic.php?f=3&t=2694 And go sloooooooooow for PETG. (It do like to jam.) :D Jules, I printed with settings that worked great ...

Given the full explanation (and thanks for giving a full explanation, it helps a lot), I can guess what is happening based on at least one similar experience. I think the hot-end is jamming, where a "jam" is better than a "clog" (not that there's any rigorous dictionary definition, mind you) becaus...

Hi, I thought I knew how to troubleshoot my printer, but I guess it that asked for troubles :-( . Short version: when I try to extrude the filament seems to "bunch up" inside the extruder guide and then get stuck (see picture). I verified that this is not a clogged head (problem repeats with new hea...
