Two AFOLs here who are stuck on the Lego Typewriter build. We have built large and complex sets before, but this one has us stumped. We have now rebuilt Sections 5-7 twice, but we can't get the carriage mechanism working.
See the video at Reddit. All of the gears seem to be turning, and the carriage moves when we manually press the lever next to the lime green part on the left side of the back (looking at the front). However, the keys don't move the carriage. When we push the carriage all the way to the right as shown on page 170 of the instructions, typing on the keys does not move the carriage back to the left as shown on page 171.
The keys don't seem to be striking any of the mechanisms. The grey and blue pieces (closest to the keyboard in the back section) are moving, but the keys and the carriage don't seem to be connected. It's hard to describe, but the video shows the problem more clearly.
Can anyone help troubleshoot this?
