My extruder keeps stripping the filament inside, WHY??? February 04, 2014 06:27PM |

No matter what I try to print, it strips the filament inside the extruder and stops feeding it through. I can pause the print, and tell it to extrude 5mm, but nothing comes out. I have to reverse the filament and pull on the filament to get it to back out. I can see where the filament is being stripped/where it stopped feeding through.
I've had this problem for months now and have all but given up. I've got a Makerfarm, Prusa I3, 8", ABS, 3mm filament, .50 hot end, heated bed......Anyway, I thought maybe my filament was water logged from sitting out in the open for months, so I ordered new filament and today finally got around to opening it and trying to print. The filament is made by Folger Technologies and I've been through a rolls in the past without any issues.
Again, I thought maybe my filament was soft from being in the open air, but this new roll was vacuum sealed, with a desiccant pack.
Any suggestions?

I don't think it's the hot end is faulty. I have the temp probe and it always shows the tip is at 225C
So you are saying I should release the spring pressure as much as possible (when it fails to print) and then slightly push the filament and see if it moves? I'm pretty sure I've done this, but I'll try anything again to help rule out my problem.

I had the same problem on my reprap.cn printer.
Make sure that the way through the hot end has the same diameter.
I had a cavity at the inlet . The PFTE hose for the filament feed was not all the way in.
So when the hot end got hot, the heat traveled upward and the filament got compressed into this cavity.

sorry I meant "print head", but this morning I pulled everything apart there was lots of little plastic pieces and the hobbed bolt had some plastic wedged in the teeth so I cleaned all that out put it back together and there was absolutely no change at all.
As for the filament manufacturer, it's made by a company called Folgers incorporated. I've tried calling and emailing them about 15 times with no response. if this was my first roll from them I would think that maybe that's my problem but its not, I have gone through two or three rolls without any issues at all.
since colin (from makerfarm) is here in Salt Lake City, maybe I'll just go purchase a roll from him to see if that is my problem.
am I missing anything?

I forgot, sorry. I'll try again tonight and see if I can get it to push through. this morning I extruded 30mm without any problems, so it seems like it only messes up shortly after I start the print, actually after the first layer. so should I try lightly forcing the filament through as its printing?

Hey,
Depending on how the hand extruded filament goes, if you don't have any issues with it, try extruding 5mm of filament at a time with the control panel, if it still performs flawlessly after a decent amount of extrusion, you can narrow the problem down to the gcode. It's possible you're trying to extrude too fast. Have you configured the extruder stepper in the firmware properly?

Here are screenshots of my speed menu for the "Print" and "Printer" tabs in Slicer after loading my STL file. I always load my config file each time I open the program and I never change any of these settings. Maybe something, somehow was changed and got saved, but I highly doubt it. Do you guys see anything wrong with any of these settings?

Vetteguy,
I've started having the same problem with the same setup, except I have the magma hot end with the 0.4mm nozzle. I think we have a blockage of some kind. I've noticed that there is ABS squeezing out between the extruder barrel and nozzle on my setup, which doesn't seem good. Anyone else experienced this?

I just noticed that I have the same thing. right where it goes from the black plastic cylinder to the brass nozzle? Mine has black ABS oozing out that I can see through the kapton tape.
What is the best way to clean this? Could it be the black cylinder starting to melt from the heat?
