G940 rudder pedal spiking

[Ack-Ack]

Ah, thanks.

Still using my TM Elite rudder pedals I bought back in '98.   I converted those to a Hall effect sensor a while ago with one of Cubby's upgrades.   They're not USB though, and when I tried the game-to-USB converter I used to use with them before the Hall conversion, it didn't work properly.   Not sure if the Hall conversion would cause that problem, I would've thought not.

No worries, still hanging in there with the Cougar.   

The Hall sensors or a potentiometer shouldn't have any affect on the gameport to USB adaptor and most likely the problem is the adaptor itself.  Does your adaptor have a switch or maybe driver selections you can select the number of axis?  The old Rockfire adaptor I used to have had switches for 2 axis, 3 axis and 4 axis controllers and then I had to select the same in Windows game controller applet.

ack-ack

Hello all - time for a Logitech update:

My 2nd replacement G940 arrived this week.   It has the same problem as the previous replacement - wild spiking on the rudder axis, and the right toe brake is either off or full on - there is no gradual transition as with the left toe brake.

I always uninstall the previous Logitech software and install a fresh copy from the new installation CD.    I am using Win 7 64-bit.

I don't know if you've been paying attention to the forums at logitech, but it appears they are very very close to having new drivers to fix a lot of these issues... we're talking a few days... so just hang in there and see what the new software does before jumping the gun any further.

Beyond this, I can't help.  Good luck

I do hope its a driver issue.   I've updated my support ticket at Logitech; we'll see what they advise.

Thanks for the heads up on the drivers impending release.

Oboe, I've had the same problem with my G940 also.  Most of the time, both brakes lock up, and sometimes just one.  After trying to recalibrate with the Logitech software and having no luck, I went into the AHII clip board. In the Map Controller, I select the rudder pedals and calibrate each, close the clip board, and am good to go.  Most of the time the brakes will operate normally.  Occasionally, when switching to another aircraft the problem will occur and is solved with clip board calibration.  The problem also seems to occur almost everytime after I turn the computer on.  Hope this helps.  I'll be watching for the new drivers also.

does the logitec software work in unison with the AH calibration or do you use one or the other?
I got the impression when I was using my X52 that less problems occured when I disabled scaling in AH and just used Saitek software

The logitech software is stand alone.   I am able to access the calibration routine right after I install the software, after that I can't find how to get to it.   But I can get to a properties window that shows the spiking.

Same in AH calibration routine - the advanced tab for the rudder axis reveals the extent of the spiking (I can also just go OTR, select external view and watch the rudder whip back and forth as I try to hold a steady, medium input.   Full deflection seems to work fine, it's only partial inputs.

Only the right toe brake has a problem - its either full on or full off, unlike the other toe brake.  This also shows up in both AH and Logitech software.

Logitech service reps have asked for more time to escalate my situation to a higher level.   I hope this gives them time to introduce new drivers.

Is spiking a result of mechanical/electrical problems?

I have just bought a CH stick plugged it in, there was spiking.

I disabled the scaling in AH etc and spiking stopped.

I think it can be either.  I've taken the pots in my Cougar apart several times and cleaned them to cure spiking.   I think it could also be caused by defective components, but I've had this with 3 G940s in a row, so I think its not likely (though still possible).
