I appreciate the advice you are getting from Pololu, but even David Grayson himself has said that you should discuss with the guys at x-sim.
Even he was stunned that we run JRKS at 30 amps continuous, not peak.
Plenty of us, including myself have used and destroyed JRKS over the years.
If no one else here has used capacitors for a "noise" issue, then you are welcome to try, but you are on your own.
When I ran wipers, if there was a problem with the motor being earth isolated or just a bad motor, I bought a different one and that fixed my problem with wipers.
Now I run proper motors, being these
http://www.motiondynamics.com.au/worm-d ... orque.html they are perfectly isolated and quiet motors. Much better than wipers by far. Yes, they cost a bit though.
With "noise" NEVER HAD A PROBLEM!!!! Granted a shielded cable to the pots may help a bit , but "noise" is NOT a comport error problem. "noise" is more a feedback jitteryness to x-sim and slightly off motion.
I have had comport errors in the past, but that was only because I was using the front ports on my PC box, of which are connected to a cable to the motherboard. I now run USB extention cable and plug my jrks directly into the motherboard at the back. No more problem.
The other thing that caused comport errors was a lousy power supply not putting enough power into the motors and causing the jrks to crash.
And the other thing again was running big arse motors and figuring out PID issues. And then setting motion, blah, blah.
So please prove us wrong and show us capacitors work if you need to.
