I followed this tutorial (youtube.com/watch?v=3vS4_V_lJ9A) to analyze the motion of a gear train (drive.google.com/drive/folders/1iq75zYOcFWaWFZeucYx9aPnbf2fSsNLA?usp=sharing) but although I think I have correctly followed all the steps the motion is not what is expected. My goal is for the motion to correspond to motion study 2 of the tutorial shown at the end at time 20:40. When you suppress the concentric and gear mates in the tutorial, the gears move correctly but in my assembly the central gear translates. Can anyone explain what I am doing wrong? My gear train assembly can be accessed through this link (https://drive.google.com/drive/folders/1iq75zYOcFWaWFZeucYx9aPnbf2fSsNLA?usp=sharing).
