Mysterious loose cable

Recommended Posts

Posted · Mysterious loose cable

Greetings!

I recently installed a new Olsson block on my UM2 and think I have inadvertently damaged the temp sensor as I am now receiving a temp sensor error upon heating up the hot end. I understand that this is fairly common when replacing the block so have already ordered a replacement sensor.

In preparation for the new sensors arrival I thought I would open the bottom panel of my UM2 and have a look at the PCB and connections.

I have come across a loose cable and at first thought may be the cause of my temp error but soon realised that this connector is not the Temp2 cable responsible for detecting the temperature of the hot end.

Can anyone shed any light on what this cable is for and if it should just be left unconnected??

Many thanks,

Matt

Is it red and brown? If so, you can ignore it, it should be left unconnected.

As for the error. Make sure your temperature sensor and heater is fully inserted and held firmly in place. Also check that the block or nozzle does not touch any part of the fan shroud.

It is red and brown, thank you.

I have checked and double checked the the sensor/heater and have ensured that the fan shroud is not touching the block or nozzle.

The error appears as soon as you switch on the machine now.

I will install the new sensor as soon as it arrives and let you know how I get on.

Thanks again
