Hi all

I have a question about this device in https://www.thingiverse.com/thing:2948680/files. Where can I find more information/reading material about this type of mechanical movement (for example, what is the ratio between the motor circle radius, pin location and the table bearings).

I wish to print a smaller one but I do not know where to start.

Thanks

Welcome, @JohnSa !

Do you need an specific output for the sample to be rocked?
Example: frequency, maximum angle, weight of sample, way to fix sample to platform, etc.
The one shown in your link has an electronic panel controlling the motor.
It seems that because of that, the frequency and duration of the oscillation can be programed.

Welcome to PF.

Start reading here; https://en.wikipedia.org/wiki/Linkage_(mechanical)

If you can post your required dimensions and the rocking angle limits, we can compute the length between the pins, and so the pin positions on the components.
