Pot axis display with Frex style sim

[SimHawk]

Hello,
While I am waiting for my valves I am testing my Frex style chair with pots mounted.

Is the red dot in the simulator diagram supposed to follow the cylinder axis/pot feedback or the simulator axis? On a Frex like chair when the simulator is full forward both the cylinders are extended and the red dot is up in one corner of the diagram cause both pots are in one end as well. I had expected it to follow the center line up and down when I move the sim forward and backwards.

How can I tell the profiler that I have a frex configuration?

At the moment the dots are 45° degree false oriented as Frex setup.
To get a Frex setup, you have to find the left/right values
and add twice g-forces, one for x, one for y.
Invert now one of this axis, because they have to work against.
Then you have to find forward/backward and add them as g-force effect
to x+y. You have to reduce the maximal percent to under 50. It is
impossible to drive them all the possible way.
You now should have 5 lines in your profiler calulation table (right).

Thank you. So during calibration run, when profiler says "Simulator goes up" it is actually extending one cylinder and my frex chair will move to e.g. fully right?

@egoexpress - I'll try the profiler setup that I found in your link.

BTW: A friend and I had an entertaining and funni driving session this weekend. Since the valves are missing we moved the chair by hand while the other drove! LOL! Who said I'am grown up??

The calibration run is dedicated for RnR type sims. It is just important that it extends both cylinders to their /startend positions one by one. If the direction isnt right, you just have to exchange the air hoses connected to the cylinders.

You need a frex type valve matrix config as well. Please ask Ferrari_man for it. I have given him the config file.

@egoexpress - You say it is dedicated for RnR. I assume I do have to run it in order to get my pots calibrated? Just that the "up" and "down" in the dialog boxes have no meaning in a Frex setup?

And one more question. Profiler says during calibration that a potmeter has too little travel or something. How much of the 256 values from the AD must be in use for profiler to accept it?

[egoexpress]

make sure you get the max travel without destroying the pots.

I dont have it in mind, but you need almost the full length.

Make sure to use linear (not logarithmic) pots!

I have alredy broken one pot! I had them calibratet to almost full travel, but one control rod jumped off and I reconnected it wrong with pot destruction as a result- I use 50k linear conductive plastic.

@ Sirnoname - What you said about 45 deg rotation is actually very describing. I made a profile yesterday and tested it with the LFS plugin. Although I got four lines, not five in my G-force calculations. Thank you for your help folks!
