I bought an Up Box a few years ago for my school (I’m a French D&T teacher) and now I have an issue that I’m not sure about how to solve it.
Like you can see in the photos below, the strip for the initial positionning of the head has moved from the sensor. Should I just put it back in a specific way (if yes which one?) or is there something else to do (change the complete sensor?).
Thanks a lot for your help.
