Question SaberTooth 2x32 SCM3 Arduino - output testing doesn't move the motor

After a while away from here when we doing some rebuilding in the workshop i picked the build up a few days ago but struggling to make the motor move in output testing in simtools engine.

(in photos is shows simtools demo because i have a new laptop and haven't patched the diy version i have bought yet).

While simtools testing i did close the scm software before starting up simtools. My settings are posted below.

I followed the tutorial from blazinH : https://www.xsimulator.net/communit...ket-serial-pid-motor-driver-w-softstart.9277/

and when the motor is powered on it does move correctly to the zero point so to say.

If anybody has any idea what im doing wrong or what mistakes i have made i am happy to hear.

Thanks in advance.

I just found out i was using the output on motor 2 from the sabertooth, in simtools i sway and surge to axis2a and it worked.

easy fix luckily but maybe a bit dumb

Just have to figure out the jittering now when using the square structure in scm3.

If you got some pointers that would be nice. Tried a few things in the pid settings but not a lot of luck so far.

If i up the pwm max to a bout a 100 it jitters that hard that it goes mental and i have to shut it down because it just keeps on rotating full circles on way.

here a quick movie of the jitter.

Been reading that pdf file and watched some of the video's. But i can't get rid of the overshoot unless i lower the proportional dramaticly or the pwm max. If i add integral only by 1 it starts to jitter even more. When adding derative even up to a 1000 it still overshoots.

Having such a low proportial just doesnt feel good. In your previous post you mentioned try 235. I tried that and it just went nuts with pwm max at over an 100.
