Ultimaker Original Plus filament stuck in Hot End Isolator Coupler/tube

[ayeohmy 0]

Hi, 

 

I have an ultimaker original plus that has something PLA filament stuck in the hot end isolator coupler and hot end isolator tube. I tried heating it up using the heating block. I tried soaking it in boiling water. I tried dripping some acetone into it but I can't get it unstuck. 

 

I'm in the US and I can't find any replacement parts that will ship to my location. Is there something else I can do or place I can find a replacement part? 

 

Thanks, 

Audrey

I've been able to clean things up a few times by heating it up with a hot air gun and blowing compressed air through it...

The PTFE hotend isolator part has a tendency to deform over time, especially if you print with "hot" or temperature conductive materials. Once it does, it will cause blockages, and it should be replaced.

 

I think you can still find replacement PTFE parts from chinese manufacturers on aliexpress.
