Posted July 5, 2024Jul 5 Hello, I have a question. I am currently building a lego pneumatic motor, that means building without electricity but only with an air pump as an experiment but the motor just won't turn. I have made a tiktok video where you can see the problem Tiktok video as an info
July 5, 2024Jul 5 A little hard to tell from the video but it doesn't look like you have the right timing advance on your switches. Around 45-90 degrees ahead of the piston works best, yours appears to be at 0 or 180. The design I've had success with puts them 60 degrees ahead, so when the piston is at bottom the switch is already opening, and 30 degrees later the switch is full open and the piston can expand. With a 2 piston engine you might be able to route the air to opposite pistons to get 90 degrees, that should be capable of moving itself but it might be more jerky than at the ideal spot.
