Hello all,
After several years of good services, the wades block of my mendel90 broke.
I got a new one printed by a friend of mine, and started the replacement operation.
When I disassembled the extruder assembly, I noticed that some material had flowed along the hot end. I thought it was PLA that had flowed during a failed print, so I heated it to remove it softly. I understood it was not PLA when it suddenly broke instead of flowing.
So I am wondering what it is. Could it be the car exhaust patty that Nophead is mentionning in the documentation, and which is use as a cement for the resistor and the thermistor ?
That leads me to several other questions :
> what could have caused this ? (I recently started to print a soft PLA which require a printing temperature of 200°C. Is it too much for that hot end ?)
> have I damaged my hot end ? if yes, how can I fix it ?
Thanks
Adrien
