Com Port Errors, JRK, XSim3, PC?

[Erwan960]

Hi !
I just finished my cockpit prototype based on Zyt 90-155 motors driven by 12v12 jrk. Everything works fine under jrk configuration utility (speed, pid, min, max...).

But when I launch X-Sim, I get that : "error opening USO comport..." for my 2 jrk (com4 and com6).


I am using usb cable from pololu. I have just ordered new one on amazon. Hope it will help !

Hi, is there a reason why you are using uso commands for the jrk's?
I would recommend you to use the interface plugin for the jrk's - as you can use 12bit of resolution insted of 8bit (with uso).



setup like in this video - you have toignore the part from the beginning up to 1:30min...
make sure all the uso entries for all jrk's are removed!!!

if you dont have created axis in the math section before - x-simwill ask you what of your outputs should be used for a new axis. otherwise refer to the video and assign them "manual".

Hope this helps! Your pololu usb cables should be fine - no need for other one.

It seems that I mixed information from different subjects... Thank you very much for this development.
Now I am able to correctly associate the software (Project CARS) with the dynamic cockpit without error.

Remains to adjust the motor courses and the spring tension at the ball.
