Continued from Transfer Table Staging-Part V
Just a quick update. The styrene piece I was using to trigger the photo-interrupter sensor had a blunt edge. This was causing the drawer to stop at two different spots depending on the direction of travel. One of the forum members at nscale.net recommended that I taper the end symmetrically from both sides so the sensor will be triggered at the same spot regardless of direction of travel. What a brilliant idea. It worked beautifully.
I temporarily taped some track in place and tested this with some hoppers. Here’s a video.
I am very excited! I can’t wait for the rest of the parts to arrive so I can finish this up!
