Hot end pack washer

Recommended Posts

Posted · Hot end pack washer

Hiya. I just got the hot end pack in, and theres an extra part that I dont recognize. Yes there are several references to the little washer, but no instructions on where it goes. It only fits over the threads of the nozzle, but in so doing, only leaves 3 or 4 threads for the collar to screw onto. That concept doesnt agree with me, especially when you consider it pushes up against the spring by that extra 2 or 3 mm. How about a little help there? Thanks

It goes over the actual nozzle and goes between the nozzle and fan shroud to stop melted plastic getting up underneath.

Awesome , thanks for that info!!!! I already crushed it, because yeah, it also happens to fit over the threads of the hotend. Those folks at UM should have made note of that. Thats really a good idea now because of The Olsen block I installed. It has two little slots to push the heater element And temperature sensor out case they get stuck which Would be really bad if they got clogged
