Nozzle Clogged All The Way Up - Printrbot Simple Metal

[ReidC]

Hi!

I have a new Printrbot Metal, and I'm enjoying it.
However, the nozzle appears to be clogged up.
See the picture below.
How do I get filament residue out of the top?
I have already heated to temp and had some residue come out.

Thx!

With it down that deep there is no way to pull it out so you will have to push it out thought the hot end. Heat up the unit to 220-230 and use the back of a drill bit that is the same size or slightly smaller then 1.75mm. you will have to apply slow steady pressure to push it out.

I was afraid that was the answer. Thx for the post!!

To close the loop: it might be a terrible idea, but I used the drill bit suggestions -- with a drill to drill out the plastic.
Easy peasy.
Printing like a charm.
Thanks for the inspiration!

I had some thin brazing rod that fit (.125in.). Left hot end in the Simple, removed the nozzle, cranked the Z axis all the way to the top. Take the tension roller off the extruder(single allen head bolt). Heated the extruder up to 215 and pushed the rod up from the bottom. Brazing rod is a wonderful conductor of heat. WEAR GLOVES. The plastic popped right out. WEAR GLOVES, did I say that?

Reassemble the tension roller. Insert filament and manually extrude a few mm. If it looks good, re-attach the nozzle and manually extrude some more.
Should be good to go. Don't forget to WEAR GLOVES.

Typing with two fingers until the burns heal.

Ouch! Gloves sounds like a pretty great idea!

How do you take the hot end off the printer to clean it?

EDIT: Belay that. Figured it out.
