Nozzle temperature sensor functionality test Error01

[jeroendewijs 0]

After some trouble with my Ultimaker 2(+) having unclear stops during printing I was looking for way's to find out what it caused.

The problem reveiled itself with an Error01 Temperature sensor and a halt during printing. OR it did just stopped with printing, no message just the last printing status vissible but the printer was 'hanging' in that situation. So I could not confirm if it was the temperature sensor only or for example the mainboard having isseus. 

The regular described procedure of Ultimaker did not help me but seemed to confirm that the sensor was working fine. Most of the time, the printer, turned on and not running a job, did not show any errors or halts, the problems occurs when the printer is in printing modus.

 

When you don't have electronic tools, multimeters or so, this is a simple way to roughly check a bad connectivity of the sensor to the mainboard.

Hook the printer up to a computer (USB) running Cura and select the monitor tab. When the printer is connected you can see the bed and nozzle temperature.

These valeus should reflect the actual temperatures. 

Now gently move the printer head around the printable square by hand, bend the bowden tube a little, move the sleeved wiring in several directions. Watch in the mean time the temperature valeu on the computer screen. I pulled also a little at the rear of the sensor where it appeared to have this signal break.

In my case, suddenly the temperature was far too low, or extreem high (the cooler starts to run instantly as well). Then you can find a spot where it happens. In that case you can conclude that you have a bad cable (the sensor is still OK but unable to pass through good valeus) and you need to replace the sensor and cable together (as it is assembled as one piece).

 

So take your advantage with this procedure to find the cause of the problem you face.
