First repetitive clog
I have been printing for about a year and I am now getting, for the 1st time a repetitive clog...
I clean it, works good for 1 minutes and then clog...
Change that I have applied before the clogging started:
- Upgraded from Duet 0.8.5 to Wifi
- Changed E3d V6 aluminum heater block to stainless steel heater bllock
But everything was working... until the 1st clog
Here is what I tried... I cold plugged it, I torched it (nozzle and heat break), I changed my nozzle, the compound on the heat break and a new spool... I am running out of idea.
Here are some pictures, I noticed that there seem to be a straw like filament residue...
Thank you for any assistance

Steel doesn't conduct heat as well as aluminum- that's why it gets used for heatbreaks. The temperature may be too low at the filament because the heater block isn't transferring the heat to it. Why would you want a steel heater block? I can understand a steel nozzle for use with abrasive filaments, but the heater block should be as thermally conductive as possible.
After you unclog it, can you see light through the nozzle?
Yes, I can see the light and I changed the aluminum heater block because I broke it...
I over tight the nozzle and heatbreak and ripped the threadout...
thought that steel would be more viable for me.
Go back to aluminum and don't tighten it so much. I put anti-seize compound on everything threaded into the heater block - it makes it easy to disassemble if I want to change nozzles, etc.
@nylkos the e3d documentation mentions using quite light force to tighten the nozzle:
Ant this might be useful as well:
