If you set simulation solver model to iterative 64 passes and update timestep to 1/120, the wobbling should be significantly reduced.

Thank you very much Anton, this helped

Spring joints are for linear motion, not for angular. Either use angular spring, or since you want to dampen the whole thing, simply change hinge mode to Angular Friction and increase the friction parameter, to say, 4000000.

This worked great, although I think I found the solution I was somewhat looking for using servos with an angular limit
Here's what I was aiming for
SU15, MSPhysics 1.0.2, hinged test end product with servos and hinges

I have an odd result with a test I've been trying to get to work:
I have two aluminium pieces, connected through two aluminium bars.
One aluminium piece is static with two hinge joints (each connected to one bar).
One of the hinge joints I have set up as an angular spring to dampen the fall.
The other aluminium piece is connected to two hinge joints, each on the end of the two bars.

My problem is, the system starts to wobble after 10 seconds , and after 30 seconds it spins out of control .

what am I doing wrong?

attached is the SU15 model with MSPhysics 1.0.2 and AMS_lib 3.5.2SketchUp 2015 model of MSPhysics hinged test

edit: I wanted to attach a spring (instead of using the angular spring hinge) but I believe that springs are fixed and non-movable) and somehow I can't implement this idea.

Can someone help. Ive tried deleting and reloading the MSphysics and ams files but keep getting this load error.

Error Loading File C:/Users/Brian/AppData/Roaming/SketchUp/SketchUp 2016/SketchUp/Plugins/MSPhysics/main.rb

have you made sure that the file msp_lib.so exists in the above mentioned directory/folder?

Just a heads up replying to my post:

thanks

Thank you,

the new version "0.3.0" runs smoothly on SU 15 and 16

Great work

@Anton_S yeah, I changed the name when I posted the log. Assume that the UserName is correct.

I just realized the following entries in the log:

Error; #<RuntimeError; An error occurred while trying to load Ruby FFI!
5; Access is denied.   - C;/Users/UserName/AppData/Roaming/SketchUp/SketchUp 2014/SketchUp/Plugins/SketchyPhysics/lib/2.0/ffi_c.so

and therein lied the problem Norton AV has some weird "insight WS.Reputation.1" score, which quarantines files it thinks are not safe because not many users have reported it as safe, or the developer didn't submit it to their safe-list https://submit.symantec.com/dispute/insight/ which I have done now.
Sometimes these AV are a PITA but more than that, they save one from a lot of trouble

so far I got SP3.3 working now.

Thank you!

New update will come today, and well see if it works. Sorry for inconvenience.

No inconvenience at all really glad that SP is being worked on for the newer SU versions.
Thank you.

Hi, I'm on Win7 and have SketchUp 14 (free). I downloaded the SketchyPhysics_3.3.0.zip file, installed the files in C:\Users*UserName\AppData\Roaming\SketchUp\SketchUp 2014\SketchUp\Plugins* and can't get it to work
One reason - I think - is that I have no "Plugins" menu:

but the main reason stems from the following Load Errors:

can anybody shed some light on this?
