Let's talk about clogs

Kinking above the hot end is often caused by the extruder motor getting too hot.   Is the fan still working?

I got an e3d just for extruding materials with a higher melt temp than the peek is capable of... however if/when any of my other hotends fail I think they will get replaced with more e3d's or similar(all metal) just because I think they are more bullet proof.

I am having the same issue right now. I feel you pain. I torched my nozzle and brass tube so i know its not plugged. Another forum member suggested making sure your drive gear is perfectly lined up. I have to go and try this tonight.

Let me know if you find a solution. I would like to get my printer up and running.

I will do the same.

This incident has also made me purchase an E3D.

Stevos, I did indeed see that the drive gear was not aligned with the hot end intake orifice, so I aligned it. You'll need small metric allen wrenches. If you need to buy some, I suggest the kind with the "ball end", they enable you to insert the hex ball yet have the wrench at an angle, unlike a standard allen wrench which has to be straight up from the socket head.

Although SD warns against it, I will ease the nozzle off and soak it in acetone overnight, see if I can unclog it.

So, I guess the next obvious question is, where's a man get a good deal (or a deal) on an E3D?

Thanks, guys.

And... does the E3d'S Bowden feed eliminate this problem with the kinking filament?

Here's a question. Has anyone tried soaking the clogged extruder bits in a Crock Pot, on Low I suppose, with a couple inches of acetone? Seems it would be less radical than a blow torch. I clean carburetor parts that way, with carburetor cleaner (some wicked stuff) and it works great

Sure, you want to set it out on the patio to avoid the embarrassment of a fatal explosion but does acetone harm any of the associated plastic parts of the barrel and tip? i.e. wiring insulation, connectors, etc.

BTW, I got a used small Crock Pot at the thrift store for $5. You sure wouldn't want to also use it for food, I don'rt care how you like your Chili.

Can anyone point me to any instructions about what it takes to put an E3D into place replacing the Solidoodle extruder?  I've already made the move to a Lawsy (MK4, though I have a printed MK5 in reserve), so I think the E3D pretty much just slots into place (but would like to confirm that); but I'm less clear about how the wiring works.

Yeah, I meant MK5. I didn't see the PEEK in the photos, where does it go? I just printed for a couple hours at 195C and nothing melted.

Woo Hoo! I got it to print ABS again by cutting prints speeds in half. Now, if I can coax it to print Flex PLA I'll be a legend in my own mind. Or out of my mind.
