Head included with Upgrade kit for UM2E+

[Galad 0]

Morning,

 

I've previously installed the upgrade kit and has worked awesome for some time.  We've had a recent mishap where the ID threads for the nozzles have been contaminated with PLA.  It's been cleaned since, but I'm curious: If I want to replace that head, what part would I order?  Is it essentially the Olsson block?

 

Thanks

Yes.  The Olsson block.  I sell them in USA at thegr5store.com.  I also sell a slightly better version called the "block v3" which has less heat loss to air and better heat conduction to the nozzle.  

 

But you should be fine.  Just always change the nozzle when it's at least 130C.  I usually change the nozzle at 150C to 180C.  And you can ignore the plastic in the thread.  Also I recommend you use a torque wrench at around 0.5 to 1.0nM.  This one works great:
