do we use the previous link for version 2?
Do we need to delete the version 1?

Yes, the Link has another name, the filename is the same.
Simple overwrite the old dll file, the pololu program is missing this time, did forget it to include it.

I take it the pololu program is the utility program. This has to be installed anyway to get the computer to recognise the jrks, so we can open it manually to adjust PID.

Tacking on to the folks that have used this setup, I am also using this new method. The switchover from USO was quite simple in my opinion. I dont know that I see such an increase in accuracy. I have been using 10k pots from digikey which are pretty high accuracy. I dont have any jitter. I have not tried to recalibrate my profiles. I tend to use 15-20 mathplugins per actuator. i matched my pid ms and all ms down to 5ms. my pid settings are 2/0 1/1 3/0---thats from not looking at is so I might have that mixed. But my point in showing that not all wipers are the same and not all power supplies to them are either so caution in using someone elses as when i matched the post above I believe from motiondave, my motion is supppper slow and lethargic.

I wrote 2/2 0/3 1/1 as PID for wipers, and by the way, thats what Bobbuilt suggested originally and its worked for me and at least 3-4 others.
Then you can fiddle with PID and power settings to suit yourself.
If you lowered the power settings from 600 down to 250-350, move them up again.
The idea of a "default" PID for different motors is a base line for people to start with.

yes, but if they think that is law then they might not get that great of experience. Not all PID are creted equal. Again this is my perspective.

Your perspective is accepted.
Yes not all PID is created equal.
Base line settings are not law, just a place to start.
There have been enough people, including myself , that have needed a base line to work with.
I have supplied some base lines for people. Then its up to them to adjust settings, but if a base line gets them moving, thats a good start.
As you said yourself, you may have set it wrong.
If you are such an expert, then advise people of what best to do.
I am no expert and never claim to be.
