Spring on top of the second print core

Recommended Posts

I was removing the PVA Filament from the printer when it got stuck and broke off in the feeder. I was able to get it out of the Bowden tubes by removing the tubes from the print head. I inserted the tube back into the print head and everything seemed okay at first. I changed the core so that I could use a different color and inserted the filament into the feeder to start getting the printer ready (I did follow the steps given on screen). I waited for the filament to start extruding as per the instructions and nothing happened for a long time. That's when I notice a spring above the second printcore that was not there before. Does anyone know what that spring is and know how to put it back into the print head if possible?

wtf?  What is that?  Take that spring out.  There shouldn't be a spring there.  I think someone played a joke on you?  Do you have a 3 year old who puts things in places?

 

Hi to all !

It's not a joke !

I don't own an UM3 but I had the opportunity to disassemble an UM3 print head

this spring exist, it serves to keep well in pressure the 2 level switch parts,

something goes wrong for the Orange_42 case, the spring went out from it position, For an unknown reason, I think it turned while screwing out through the hole ?

it will need to open the top head to reposition it under the condition that there is no level broken parts,

Without this spring the level switch would not "switch" perfectely.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
