Filament jam in heat break in E3D v6

Hey guys,

Just bought a V6 Hot end extruder from filastruder. I will say that it is a fantastic tool and I overall love the design, but I am currently having an issue with the heat break. The plastic expands inside of it to the point where I can hardly physically pull it out, or it may be some other issue with it. It comes down to that I removed the heat block and the sink, which the plastic was stuck in the heat break. Anyone else having the same issue or a solution to this predicament?

Thanks,
Danny

 

Do you have the fan running?

 

Yup Mike, the fan is running. I purchased a second heat break to check if it was that individual one, they are very fragile pieces (bend easily); but I ended up with the same problem, plastic jamming in the heat break.

 

Are you using the short piece of ptfe liner they include? I had a few jams prior to installing that liner (i did not use the black tube snap holder, and drilled out the hole in the extruder the filament runa through for a tight slip fit of the ptfe tube) but since i installed it, i havent had any jams.

 

Thank you for the ideas. I did not install the Teflon tubing. I do think I may have found a little lip inside the heat break, but not entirely sure yet. I have ran 3-14 hour prints to see how if it is the material. using three different colors (different additives, and the brand has never failed me before this incident) I had one jam 3 hours in, another 9 hours, and the last 5 hours. I'm running the head at 220C, I would try lower temperatures right now, but now my printer is showing me the maxtemp error upon start up.

 

The PTFE needs to be installed, period.

 

Thanks Elmoret, but could you please go into a bit more detail about the process? I would just like to know some more why this works.

 

Because e3d said so:

and they know more far more about hotends than you or I.

Out of curiosity, did you read the assembly instructions?

 

Prevents the filament from buckling before entering the nozzle.

 

Thank you Mike, I did not get the kit because I was attempting to cannibalize some parts, failed, and ended up buying parts individually. I have it all straightened out now. I did not notice some of the dimension changes in the design, so that is where my ignorance came into play. The buckling definitely makes sense in why I am having this issue.

again, Thanks Mike.

 

damn right it does.

you should actually read this stuff..... you are going to burn a house down one day

 

also protip, if you are up to making your robo (almost) jam proof you can widen the hole in the ext ruder slightly and run ptfe tubing right up to the extruder wheel like so. I did It. it took a hell of alot to jam it after this.

 

Thank you Collin for the tip, I find it very useful thought. As for some of the comments being made here, there seems to be a tad bit of pretentious going around and I think I could deal without the attitude.This is a learning process that I am trying desperately to develop, so I can deal without the foul attitude, because you are seriously not making any contribution. Which, as who I would believe to be a representative for filastruder, elmoret, please refrain from making such comments, they were not helpful at all and completely unnecessary.

People of the forums, try to to plaster a fake smile on and try to keep a healthy relationship with the other members, otherwise, no one will have anything to gain. I dont want any flame wars on here.

...um wut.... Just read instructions that's all I ask....

 

Sorry Collin, that wasn't directed towards you. And I didn't get any instructions, nor did I get any PTFE tubing with my supplies. Assembly was pretty straight forward to me, didn't think I would have needed any PTFE tubing since they were only used in the Bowden kits previously (and because I didn't get any PTFE tubing or instructions)

 

You didn't get any Bowden tube? That sucks. You should order stuff from this guys website. Printedsolid.com . he includes things that you might need for installation. Also he's a super nice guy a lot of people on the RoBo forums trust him. He sent me some PTFE tubing without me asking when I ordered my e3d from him.

Also I'm digging your avatar

 

Thank you collin. I've been to their page and I really like it. Not a huge fan of filastruder much anymore, but they do sell spare parts. BUT, didn't know till now that printedsolid sold individual extruder components. I think I found my new supplier.

 

Ya I only buy from printedsolid because he has awesome business practices. He's more concerned with getting you working components then just getting you components.
