Motion Sim w/ Surge & Traction Loss

I honestly don't actually know what the problem is right now. Luckily my father in law is down here this weekend and hes an engineer who deals with motors like this all the time but we opened it up and actually couldn't see any problem but the key had slid out of gear a little so we hit that back in, however I put everything back together and it still does it

basically has a clanking sound when it rotates one direction at a certain point (doesn't do it both directions). Possibly bent the worm gear or something with all my crashes last night (I was purposely slamming into walls for testing jrk errors etc lol), it actually doesn't affect using it, just has a clanking sound which is a bit irritating more then anything (seems worse when using jrk config as I barely notice it in any racing game itself)

I have upped my P on the pid now which is helping with adding a bit of accl etc to motion but Ive gotta test it more to make sure jrk doesn't lock up with errors if I go too high etc during crashes especially

I was previous using around 0.39 while I'm testing around 0.5 right now but we did go right up to 0.9 too for awhile and also upping my max duty etc and feedback numbers for larger motion range but gotta find the right numbers to avoid these damn jrk dropouts etc.

One issue which ive had for awhile is my bounce I get on my rig due to the linear rails which have a bit of slop up and down and motors at rear making a bouncing occur (its not the frame flexing), This is possibly the clanking sound you could hear @Nick Moxley as that video was before my motor issue last night. It's on my to-do list to stop the bounce but just haven't had time to sort it yet but I have a couple ideas to stop it which shouldn't be too difficult to stop.

testing out gt3 around Bathurst on iRacing, added a couple webcams this time

looks good man

You have - no doubts - a very nice rig! Again congratulations for this great piece of craftsmanship. Anyway I have to admit that your SimTools settings are not reflecting the real motion. No surge (hardly to see, but IMO not present), no sway, wrong heave...please do not understand my intention as a harsh comment or a criticism, I write this to show you there is more space for immersion if you will agree to dig a little bit deeper into the SimTools settings
BTW each force has to be adjusted alone, not together.

@Pit no worries at all, glad to hear any feedback at all if possible. to be honest ive setup this profile properly 30 times trying to get good motion feel out of iracing but I struggle every time to get anything great, I agree about lack of surge when I was looking at video but it is actually there however I have motor turned down quite a lot as I don't like big surge movement, I find it feels way more realistic to me to have it go slow for braking forward etc. What's your thoughts on how much it should move? I'm happy to adjust my settings further as I don't like the motion I get in iracing vs project cars for instance which feels 10x more alive while driving. With sway you say theres none but I do have it, do you think there needs to be a lot more movement for sway? and what do you mean by wrong heave? again, heave is there but are you saying I should be having much more movement again?

I do adjust each force by itself, then mix then all together, then adjust again. Could you give me more detail on what you mean please for each as 'no heave' and 'no sway' doesn't make sense to me when they are both there etc. I was putting the motion problems down to iracing physics engine more then anything as I have tried time and time again to get an awesome motion profile for it but cant achieve it. Assetto and Project Cars give me awesome motion in comparison

@Pit , IMHO, you dont have an opinion.
Ive just spoken to booms over the phone.
Motion is personal preference and because everyones sim reflects different settings, what you see may not be happening doesnt mean it is.
Booms is getting sway and heave to his liking. Just because you cannot see it does not mean he is Not getting sway and heave.

@Boomslangnz not all forces are everybody's like, so very often it is a question of what you prefer or not. Nevertheless you have to ask yourself, which forces are important and which aren't.
F.eg. do you like that the seat goes backward when you climb a short and steep hill? (Pitch)
Do you prefer small lifting to the left or right while driving over curbs only with one side of the car? (Roll)
Would you like to see your seat shifting to the left when you are cornering to the right? (Sway)
Could you imaging it could be immersive if the seat goes backward if you are accelerating or forward while braking? Also the opposite is imaginable! (Surge)
Do you like the surfaces of any laser scanned tracks? If so Heave is mandatory!

Finally all forces are influencing to each others. You have to set up all forces separately and then combine them not all together. Short said you enable pitch and roll, then sway and surge (only), then heave and roll, then heave and sway, then surge and pitch etc.

Begin with 20%. Set the value in the tuning center to 3. From there you start your experiences.

What did you smoke today?

I havent, thats probably the issue

Things are escalating when the memes are pulled out

ill do some more fiddling with the profile (31st time most likely) and lower my tuning center numbers to see how it goes tomorrow

perhaps more motion then ive been setting is the key to success, ill post a new video showing and see what you think

Put some LEDs on the back of the seat so we can see it move better in the video

I have spent months of fiddling out the forces...and still wip! btw you could upload your new SimTools settings before and if you will make a new video try to brighten the room eventually for a better analysis.

@Pit What do you think of this?

Its dark for a reason noorbeast, its called Projectors. and yes traction loss is activated all the time, because its a test where I just lowered all the tuning numbers...and the motion feels absolutely terrible to be honest but its just a test to show movement with low as hell tuning numbers

As @noorbeast already suggested the sim is very small in the video and the darkness makes it hard to see all within this small window

Surge seems to work fine. The other moves I cannot assign or allocate, f.eg. at 0:19 the car drops on the left and right side and two seconds later the seat "drops" as well...The car on the screen does something different in comparison with the sim IMHO. I will upload a short video this afternoon to show you what I mean about car - rig synchronization.
