Question ABOUT IBT2 12v or 24v

For smc3, you use in mode 2 code for the 2 x 100amp 12v à 48v dual h brige?

like i did say in the post before , til now didnt test them . just did buy them and did not look into it . got 2 projects , 1 for my old sim seat making it 4 dof and a project going on for the ferrari setup . market place in nl for sale is now 4 motors 24v 1200 watt ..with planetarie gearbox , al 4 for -300 euro , using them for sfu setup , diy plasma cutting already the sfy parts . my 4 dof motors are also planetarie drive , no wormgear .

ok, to be continued then!!

I want to make it like 35-40 degree of pitch and roll so did u mean that i cant reach that degrees withs ibt2 ?
and what do u mean about day and night like respons speed? please would u tell more difference

@Stefzouille

@Stefzouille Yes I can see your problem with possibly needing larger capacity controllers for your amp draw and the cost associated with this. My worm drives operate at around 30amp under load. They stall at 60amp! The sabretooth 2 x 32 runs with no heat transfer what so ever!

I can't comment on what you'll require because I don't know about your motors. I would recommend using a SLA 60 plus AH battery as a regenerative current power soak with what ever motors or controllers are used. It will protect your PSU's and controllers, plus give your motors the required current when needed. They are superior to PSU's for the delivery of current. Use a battery with your PSU's in parallel. Your one way diodes to your PSU's are a good idea. They look like rectifier diodes that are used with car alternators?

@Doga Darko Can you post some pics of your setup? what motors etc are you planning on using? actuator, worm drive, gear drive? it's hard to comment with no information about your design.

A practical example of what translates to my motors from SMC3, Sim Tools, and game telemetry between IBT-2's and sabretooth is what is felt when gaming. The IBT-2's did not provide as much road surface information when driving or enough turbulence or gun fire information when flying (examples of heave) compared to the feedback I get with the sabretooth. My range of motion with the IBT-2's was ok (the same as the sabretooth which was 180 degrees in total) but it was slow and had quite a bit of lag compared to the sabretooth.

The sabretooth provides instant feedback. My next 4DOF tutorial on my thread will show this in a video next week. You will see how fantastic the sabretooth works with road meshing in Assetto Corsa. Of course the other advantage of the 4DOF design, is the introduction of a second arduino. This means only two motors are now controlled by one arduino instead of three motors. This helps with the amount of information the arduino has to manage.

I did not write the code for the arduino's working with IBT-2's or the Sabretooths. Credit for this goes to @BlazinH for his SPS modification to @RufusDufus 3DOF code for the sabretooths and @RufusDufus for his H bridge code for 3DOF.

@Kevinski
ha in addition I have 2 sabertooth cards 2x32a, but my motors are 24v 750w 32a, I was afraid that it would be fair given the theoretical peak at 100a peak, but yes we can put 2 12v 60ah batteries?!? the saberts would be good!!

so yes I have on each power supply a schottky diode 50v 30a on the negative of the psu, and on the positive a rectifier diode bridge kbpc5010 1000v 50a 2 like the plan below found on xsimulator and of course 1 resettable fuse 24v 40a on the plus of the psu…

That sounds great @Stefzouille. Just check about that fuse between the PSU/battery and sabretooth. I read on the dimension engineering website they do not recommend fuses between your power source and sabretooth. Only between sabretooth and motors. Unless you use a really high amp fuse.

No, I didn't actually plug it in. I was too afraid of burning the sabertooth which costs 130th pieces I tested it by uploading the arduino code, but I preferred to switch to the ibt2 at least if it burns, it's only ten euros.. so The fuse is for the IBTs, but if I can be sure that my 2 × 32 cards are not at risk then that's really good news

@Stefzouille I'd be researching and spending some time reading the literature on Dimensions website. Don't take my word for it, as I'm only a novice and only passing on info I have read myself. You can also email them directly with any questions you might have. I contacted Dimension myself and they advised me not to use a fuse between PSU/Battery and sabretooth.

I just sent a message to dimension with the map of my engine to know what he thinks, if the 2x32a are sufficient or not..

hi i use
https://www.amazon.de/-/en/2200RPM-Stainless-Steel-Motor-XD5D90-24A121SRV-RV40/dp/B08RDHKMFR/ref=sr_1_10?crid=3HX7K3AJC8GHI&keywords=XD5d90&qid=1703854059&sprefix=xd5d90g,aps,109&sr=8-10 these motors 24v 90w 11a 1/60 reduction (36rpm)
i need 40-45 degree of pitch and roll pictures attached
i also ask a question but its hard to tell in words i make a video for it

if i didnt try its always bits my brain ''what if what if'' i must try it
if i make it possible and dont like it i turn it down to 20-25 degrees
by the way i want to make fun not control and precision lap times.

and chat gpt says 45 degree is equal to 1g and thats equal to 100km/h to zero like 2 seconds break time

I agree with @noorbeast on the lever range. Although my levers can physically achieve a 180 degree arc, they only operate 45 degree off 90 up and down on my setup. I have actually introduced spring buffers to limit them from exceeding their 45 degrees travel up and down because of inertia, as well as the software limits.

I found larger rangers of motion although possible, caused them to slow in those regions and heat the motors up more (as like @noorbeast has described) because of the effort they had to make to come out of those angles.

Hoping I'm making some sense here. And again @noorbeast is on the money. Fast accurate motion wins hands down if you are really trying to emulate realistic motion in a sim. Unless you are more interested in an arcade ride which is OK as well. It just comes down to what you are trying to simulate.

Hey @Doga Darko I do not have an answer for your question because I have no experience with the gear box style motors. I think you will find that that amount of motion will be very distracting when you are gaming. Maybe in a flight sim those ranges of motion are ok IF your motors can sustain the work load. In a racing sim you will never need so much range. You want short, sharp, accurate motion with racing sims. You need a good quality fast motor controller.

i see a video on yuotube less motion is best moniton and everybody else use lessmotion I just want to try
Yaw 2 has great degree im try to simulate its rotations.
There is a common Turkish word.
1 bad exprience is better than 1000 good suggestions. Lets try it then i share my exprience from here.
im also driver on weekdays when i got home and race without motion i get kinda bored.
and if i build something like this it must have range for 45 degree.
thanks for advices i keep in mind them.

Hi i got a response :

Sabertooth has current limit protection. So the 2x32 will not burn because of too much current demand by the motors. It will current limit at 64A on each channel.

Provided the weight load is 300 pounds or less, the 2x32 should work for this application.

That is great news @Stefzouille ! I am a heavy person and I never have any problems with the sabretooth so far. But my rig is very well balanced.

Spend the time to balance your rig and you will be OK.
