G25 Calibration woes...
« on: February 27, 2009, 05:40:31 am »
Well, it would seem my race season is over this year  :cry:

All of a sudden my wheel does not calibrate correctly any longer. It ends up about 90 degree's out to the left. I have tried everything, installed the new 504 driver set which produced the same results so I tried the older 501 driver set and no go. Tried all USB ports by moving stuff around. I am running Vista at the moment.

Went as far to clean all the dust out of my PC. I have a feeling this is terminal because when I go to Game Controllers\Properties all the buttons on the shifter and wheel are working along with all the pedals. When the wheel calibrates it goes all the way to the right, all the way to the left then back half way to center (sometimes the degree varies). I have sent a email to logitech in hopes something good will happen.

Before I go and reinstall my OS (considering returning to XP to get it going) has anyone heard of this type of issue at all? I have done searching in the logitech forums, here and a couple other places but the closest thing I find is a thread about calibration issues with a PS2 or something, not PC :(

Any suggestions or thoughts would be appreciated gents :)

 :cry: I want my wheel back  :cry:

Hi Stein,

Thank you for posting this however I had tried the clear calibration tool last night to no avail.

Hey Buds I know this may sound wierd but, plug the wheel into vir just to see. It might be like a slap upside the head to it. Then reconnect to tower. Hope it's not too silly of a thought.

I was thinking of bringing it by your place tonight to swap out for yours (since you already have the software installed) I am pretty sure it will do the same there, I am 99% sure it is a hardware issue inside the wheel.

I can run to the store for you also... will I need to run by the bank or ?

  Yes good idea for trying the wheel here. It might just need a jolt that way. Hope that makes sense  :D

Below was a response to the message noted above, do I need to run down to your bank or just come by?

Well all is not lost... A friend has offered me his spare Momo wheel to use until my G25 issue is sorted.

Thanks Richie :)

As for my wheel it is definitely the contraptions inside that move the wheel to the left, when calibrating on Dee's PC it would spin to the right then die out spinning back to the left. I hope logitech will replace under warranty.

They should replace it under warranty. I have no experience with that, but from what I have heard it should be no problem. Glad you have a back up! :)

They just did it for me and the wheel was 14 months "old"..
Just be patient... I think they know the problem and they will replace it.

Good luck !

I fixed the wheel a little while ago now... Here is the post I made at TWiP about it :)

OK. Here goes.

You will notice the picture below. The red circle highlights a cap on the back end of a Servo. Inside there is how the calibration is accomplished (I don't have pictures of the inside but may in the future). Under the cap which is easily removed with a small flat head screwdriver is a circuit board with an LED light and a small COG (I guess) on the end of the Servo shaft. The COG or tiny wheel has a bunch of holes in it that directly line up with the LED light.

So you power your wheel up, the servos spin the wheel all the way to the right. Then while the wheel is spinning all the way back left the LED is on and the light passes through the little holes in the wheel to a receptacle. I believe the receptacle counts how many pulses of light go through while the wheel spins left. Say 10, 000 pulses. The wheel then knows that it is 5000 pulses back to center.

What happened to my wheel is that little tiny plastic wheel (COG) with the holes wasn't attached to the Servo shaft any more. It seems they are just a quick press fit, there is no key of any sort locking the two together. For the moment I have glued the two together with some strong stuff but will probably have to hack saw the servo shaft in future to help the plastic, glue and metal bond better. Time will tell for that though.

Well that's all it was that broke my $300 (at the time) wheel  rotfl I am glad I just went ahead and looked around a bit in instead of other going down other possible roads in front of me  :tut:

I will say this though... I removed the screws on the metal plate facing you in the picture (the servos are protruding from it) and Logitech sure put some effort into their force feedback assembly  thumbs up
