Spiraling out of the body tells me that the filament path is not lined up with the hotend. That explains why you observed it happening with a few different hotends. I doubt very much that it is the E3D at fault since you observed the problem with multiple different hotends, though you should contact them (E3D) about it (I am just a reseller).

3D printing while camping. Wouldn't have thought to do that.

Followed the advice and bought an E3D extruder from Filastruder. It does the exact same thing. It will print 2-3 layers, then the extruder sticks and the filament spirals out of the body. It isn't clogged- it will pull right back out. I've leveled the bed, I'm using the basic settings in Repetier, and I have the extrusion speed set lower. I've tried ABS and PLA, high temps, lower temps, different speeds, nothing works.

I got a Flashforge Dual Extruder for $500 on Ebay, and haven't had a single problem other than an occasional print not sticking to the bed. I took the thing camping, and it worked, outdoors, without even a bed leveling. I'm done with Solidoodle and Filastruder. This thing is going up on Ebay tonight, if anyone wants it. (Solidoodle 2 Expert with E3D extruder, spare standard extruder, 2 glass bed plates, and a bunch of printed parts.)

Ok, Thank you..

Those instructions should be fine. The Sang board is much easier to flash firmware than the newer printer board.

I went through 3 J-heads before I got sick of melting PEEK...Plus its nice to be able to regularly print at 250C+ with no worries

Sounds great, I'm waiting on my E3D, should be in this comming week, I've got my extruder printed out, and will mount everything together, see photo...

I will need help with the max temp modifications on my SD2, where do I find the best instuctions, I have the old chip 644p.. Is the Soliwiki page ok to follow? http://www.soliwiki.com/E3D_extruder

Thanks for any tips, I do not want to fry my board!!

It won't even push the filament through the nozzle on Manual, with me pushing it, so it isn't Z-height or stripped filament. What's puzzling is it has done this with four different heads, and mix-and-match parts from the four. I wouldn't have thought I got three bad hotends, especially since it started with the stock SD one. (They DO wear out, right? I've printed enough to wear a notch in the ABS filament guide.)
The filament I'm using is 3-week-old PLA from Push Plastic, stored in a tub with a big container of dessicant. It's dry enough to snap pieces off when bending.

I would say it is clogged and it is probably time to stop saving a buck on cheap J-heads and order an all metal hot end. I have never had any real reliable results from anything other than all metal hot ends. The problem with PEEK style hot ends is that they clog if you leave them on (idle) for more than 5-10 minutes. There are several options but two of my favorites are the E3D and you can buy them here. http://www.filastruder.com/products/all … e3d-hotend
I also like the Hexagon Hotend and that can be found here.

Something I wrestled with in the pre-E3D days was getting the brass barrel to seal against the PEEK. If there was the tinniest gap between them, and ABS plug would form. I really never had much luck reconditioning hotends until I did 4 or 5 and got good at the process. Around that time, the E3D became popular.

OP We are seriously here to help. A couple of options with your problem of clogging. First off if your hot end truely is as clean as it says then it isn't clogged. You are probably dealing with filament that is saturated with moisture. You can try different methods to dry it out or better yet order up some Octave filament. It isn't the best but it is fairly consistent and usually shows up dry and ready to print. The other thing is if your z-height is set to close to the nozzle it can create back pressure that can make the extruder strip the filament. The tension arm needs to be just right I like to set it to extrude 100 mm's and put tension on the filament. This will allow you to adjust the tension to a point where it has the best pull. Past that I would upgrade to an E3D.

They were smashed flat apparently. Never a dull moment.

Hmmm. I could use some shotgun chokes maybe I should just order a filastruder.

They're all bad, just in different ways. I had a customer request UPS to Mexico, I obliged only to have the package returned because it was "agricultural". They didn't like the pine wood block that was inside. Never an issue with the half-dozen kits I've sent via USPS to Mexico.

I can't ship a kit to Asia/Europe for less than $100 via FedEx/UPS. I can ship for half that with USPS (though it takes longer).

UPS/FedEx is more reliable, but more costly and more stringent on rules. On the other hand, I've had USPS packages show up to customers without a box at all (just the parts in a bag), and with shotgun chokes inside (I do not include shotgun chokes, nor do I even own a shotgun).

Sorry for the derail, OP.

And they wonder what is wrong with their business model It's just too bad there isn't some other private company they could learn form... Oh wait UPS and FedEx seem to be profitable I wonder how they do it
