Topic: my first really big jamming issue....

Hi guys...

Last week, the filament I was printing jammed, and was stick in the hot end for apron an hour. I pulled apart the extruder, and with the help of Lawsy, blowtorched the barrel and tip.

Yesterday I spent a few hours getting i all back together again. Filament came out, it all looked great. After a short test, I proceeded to a 2 hour print, only to have the extruder jam again 10 minutes from the end.

I have been talking to SD, but the best they can tell me is this -

"Black filament has been known to cause issues with the extruder sometimes. This is true of all filament manufacturers.

We have determined that they recycle any filament that could not be sold, melt it down again, put some black die in it, and then re manufacturer it as black filament. In reality they use many different colors of filament and mix them in this way.

Try bumping your extruder up to 210C and let me know if that helps"

I get filament coming out, after taking a guitar string and poking it threw the nozzle, but it comes out thin, and in clumps. Every time I extrude, it balls up on the head of the nozzle.

Anyone have any ideas that can save me from another strip down sad

Re: my first really big jamming issue....

Looks like another clog, unfortunately

You could soak just the end in solvents and hope it softens whatever is making the clog but I think the best bet is a teardown.

Re: my first really big jamming issue....

I think I need to print out lawsy's Mk5...

Tearing down the acrylic plates is nerve racking! I already broke a piece, but fortunately was able to get a laser cut replacement where I was! tongue

I'm going to try and push it threw, if not, teardown it is...

Got the jam cleared, but it took a heap of work.
I ended up blowtorching the feed tube again...

Definately print an MK5.  It will save a TON of time spent taking the acrylic apart.  You might want to look into an E3D as well.  They clog much less than the standard SD hotend.

Re: my first really big jamming issue....

Im looking at the MK5.. Have you done the conversion? Do you need any parts, or can you use all the parts from the SD acrylic mount?

Re: my first really big jamming issue....

I have done it, and just used the screws from my old extruder.  Technically one more screw is needed to hold the hot end locking arm I believe, however It holds just fine using a blank accessory clip on the outside.  Also, print 2n2r5's beveled variant extruder body in addition to Lawsy's (also on the thingiverse page).  My hot end wouldn't fully fit into the original as I used slight overextrusion to increase strength.  Luckily I printed the beveled variant too, and it was a quick change.

Re: my first really big jamming issue....

Got my printer finally cleared, and its printing very well. First thing on the list is to get a MK5 printed and installed.

Now that I can print, I now am hooked at making the printer work as best as it can.

Just out of curiosity, has anyone built up their own hot ends for the solidoodle?
