Issues with 21313 IDEAS Grand Piano

Recommended Posts

Ok, I am building the set right now but ever since the testing steps in the in instructions I’ve been having trouble making the thing work properly. 

i guess the orange beam (see picture) should be perfectly horizontal or vertical but it hardly ever isn’t. There always seems to be a tooth off of the 24t gear. When I try to fix this by adjusting the gear there seems to arise another problem. There is a calibration button in the app but that doesn’t fix the issue either. 

thing is: calibration works but as soon as I lift the grey stop beam, the orange beam is off one tooth. 

Result: the long axle making the keys move won’t rotate when I play a song. 

also: the smarthub keeps on lighting up in orange and blue. 

who can help?
