SimHawk's motion simulator

[SimHawk]

Thks a lot
You only use distributor 5/3 open and card velleman K0855 for pneumatic assembly?

I use 5/3 center closed and one Velleman K0855. And one way checkervalves for regulating exhaust port air flow. (Cylinder speed control)

arf closed what i said^^.
Are checkervalves necessary?

The needle check valves controls the air flow and thus the cylinder speed. Pneumatic theory I found on the internet says that to control the force of the cylinder adjust the air pressure, to adjust the speed - adjust the airflow. And restrict it at the exhaust port (not input port) of the cylinder. See below for more info.

I found this on the web explaining the best way to control an air cylinder:

As a result, air flow into the cylinder ports at either end of the cylinder is totally unencumbered providing high-force piston movement. The piston is trying to go fast and at full power, but since the exhaust flow of air is impeded by the cylinder flow control, the piston moves with full power, but at a controlled and desired rate.

hello
i have a problem to test velleman card:
I just connect velleman card , relay card and the potentiometer, when I plug the cable "clamp" to "0" relays card, Relays are not working

when i disconnet "clamp/0" cable , relays works
why?
if you have an idea
thank you

hello
I need your help soon if you want it! well
your tire simulator work really well on the last video!
I ordered 4 dealer 5 / 3 center, because I had 2 open center.
I'm in the stage settings, and I certainly need your experience.
for the matrix I already have a first test, there is progress on my post:
simulator-frex-home-made-in-france-t469-130.html
I have some questions:
the axes are offset by 45 °, it is not a problem with the information for direct X who are in the right direction?
if the right of the simulator is in the left corner ,and left in the game/direct x is in the normal left how move the simulator?
I do not understand this point!

I have another question:
After calibration, the simulator center?
I have no effect on the board Velleman after calibration, I did not feel that the simulator test center
thanks

hello,
I need help for the effect in the profiler for GTR2
I do not know how to apply the effect to be in the right direction
have you a .rnr for my simulator "Frex design"?

thank you
