Can't get PLA in to the machine....

Recommended Posts

Sounds like a suspect connector on the temperature sensor cable. I had a bad sensor wire, only fixed by changing the whole thing.


Thanks! One more question... Do you know what it can be when I'm printing something that takes about 10 hours so after 5 hours the temperatur will drop rom 210C to about 40 - 60 c for about 10sec and then back to 210 c and again and a again until the machine says stop...

I have a UM2, so it may not be exactly the same but try moving the cables in the area of the head to see if anything happens during a test print. If you get an error when you move them, you have found the problem.

this is something on nozzle changing




I'm new with this wich wire is it? And how can I change the nozzle?

On the print head the blue light has to be on, really crucial... and the 2 wires in the little green block fastened well, check those, they are very thin an can loose their grip.

There are two white connectors: black/red are from the fans, and a 3color connector from the heater block. This one can wiggle itself loose during printing, so keep an eye on this one.

There is also a spare wire, not connected, can be used instead of the other 3colored one, but change the other end at the electronics board as well when switching those.

Remember the wire colors and check if they are all ok at the electronics board.

    • "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.
