Wire disconnected and bed crashed in extruder

Recommended Posts

Hello everyone,

 

I received my UM2 yesterday and when I was ready for bed-leveling, I followed the instructions on the LCD and the bed crashed on the extruder. I immediately turned off the printer and after I unscrewed the screw z to put the bed on the bottom. I tried again and the bed is still violently collided with extruder and bed was distorted by force. I am afraid of having damaged my printer .. I looked at the circuit and a connector there was disconnected! I do not know where it goes, I do not know what to do.

 

Few picture of the connection problem:

I have not yet managed to make it work properly and I look forward to my first impression!

 

I hope someone can help me here,

 

Thank you in advance

That wire isn't supposed to be connected to anything.

The only wire relevant for bed positioning is the two black wires twisted together that goes to the z end stop - in your third picture. Is that properly connected?

I presume you took the glass out from under the bed, and installed it on the bed. With the power off, you should be able to move the bed up and down by hand - do you see/hear the screw sticking out of the back of bed against the wall? That should trigger the end stop under the base. Do you hear it clicking when the bed gets to the bottom position? And unclicking when you raise the bed up a bit?

    • "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.
