newbie diy 4 dof ferrari p4/5

starting to build 4 dof diy prototype from mdf wood . with 1/3 scale ferrari p4/5 polyester body . body is with permission from Glikenhaus to manufactering . using all cheap materials for building the prototype .
im into sim racing some time , now it is time to upgrade to motion sim racing . did read alot of post in this forum , helpt me alot , i,m not there yet , stil learning . 4 dof is setup with smc3 and moving with only 3 dof . based onto arduino uno with 3x bts7960 and smc3 . im now into downloading the simtools and from there learning how to setup and get this project running with a game . based onto ps 4 .
the p4/5 is polyester body only . need to complete it fully . windows , lights , grils , enz enz .........1/3 scale , so you postion is sitting 1 seat in the center. wil post some pic here from building the prototype .

hi,
that’s pretty!! what are you using as a motor?
I am also on a current project and smc3 and ibt2.
great project!! câlin :

for the project i,m using windshield motor , 24 v with 24 v 21 amp 500w power supplys and 15 amp fuse between motor and controller , but some bigger one,s like normal and with 2 carbon brush one each side . convert them to straight true shaft 20mm thick . in the pic there is a 24 v normal windshield motor and the bigger one . smaller is 77 mm diameter , bigger is 95mm. wiring is almost done and will testrun it this week with lfs . the smaller 77 mm motor im using for yaw. for now arduino uno wil drive 3 motors , im looking into it now onto this forum for using arduno mega ore a second arduino uno for driving more motors .

vouss I plan to use 2 arduino r3 with 2 actuator motors per card

maybe that is my next step , first to try and setup 1 motor running , learning how to wire up and software settings with smc3 ..did already try it , thx to this forum setup was easy , 1 motor running now , pwm max to 255, pwm rev 180 . ibt driver is about 26 c heat after letting it do motion for 20 min ...without any weight to lift . windshield motors themself are about 22 c heating up .amps i dont know . what i dont like ...... the pinconnectors to arduino connection . already 1 pin connector did going to fall out of the arduino . thinking for soldering the pin connectors to the arduino . for testing now it is ok ..happy to see already 1 motor moving , wil wire up the other 2 and putting the motion box onto my playseat with 3 dof working , without the yaw for now . for the ferrari project i already got 4 x 750w servo drivers and motors . into now for cnc alu accurator parts for it . not gone print the parts . got a 5 axis cnc here ad home and a cnc plasma cutter table for making mounting plates . playseat i already used for years , verry nice sitting position , you can rest your arms and legs , verry nice sitting position for long rides ..sound onto the seat works also great . had it first on my tv sound and screen , sound onto the playseat is much nicer .the bas module is fibrating the seat ...... playseat is cheap to make and stil holding up . mdf and some trespa parts and 3d printing parts .everything in autocad files .

1 problem solved ... arduino connectors , did buy proto screw shield for arduino 5 euro amazon

update , did order another arduino uno for adding the 4 axis . got it al running now with 3 dof with simtools . next step is to figure out how i get it running with ps4 . would like to keep the ps4 because did buy al the games for it . main games are the dirt rally games .... so wanting to setup the simtools working with ps4 and if it wil work with dirt rally . udp and network setting up is new to me , so lots of reading for now for how to setup , didnt find a ps4 plugin ? btw : got wiper motors 95 mm with 2 coils and 4 carbon brush . did use for now 1 coil en 2 carbon brush . 1 motor did lift me up easy 78 kg . did make a platform for testing , did buy me a joystick for testing the platform , but til now i cant download the joystick plugin, no permission is says ?
some questions:
1- is simtools compitable with ps4 ? ifso is there a plugin needed ?
2-is ps4 dirt rally compitable with simtools motion ?
3- i did notice that axis 1 and 2 in smc3 settings the fpwm is nice adjustible in settings , axis 3 only got 2 settings ? 4khz ore 31 khz ? because the analoog output of arduino ? with my second arduino uno can i correct this ?, so 1 arduino driving 2 axis so i can adjust fpwm correct ? and the second arduino the other 2 axis with adjusting fpwm with 10 to 35 settings /adjustible ? ore is this not possible because smc3 showing only 3 axis to adjust ?
4- joystick plugin . got the error no permission to download ?
5- ps4 network , i playing games onto ps4 with network, if i set simtool to ps4 udp , can i only play simtools with udp ore is my normal ps4 network for playing games stil working ore not working because the udp setup ?

hi , for arduino limitation:
Updates Version 0.6

• Added ability to change PWM freq (5,10,15,20,25,30,35 kHz for motors 1 and 2) (4 and 31 kHz for Motor 3 - Arduino limitations)

update , second arduino is in , added connector shield onto it , programt it in smc3 , did put smc3 software onto it , using 2 com ports now direct via usb to pc , so 1 arduino into pc with usb and 2 arduino into pc onto differend usb port , not with a usb hub , wil wire it up this weekend and do a test . i think with this setup stil only 3 dof , need racingmat arduino code and some rewriting ...for 4 dof

i got lots of these 2 coil planetarie windshieldmotor. is it possible to get 1 signal motor output from the arduino to drive 1 ibt motor , the same connection wiring up to another ibt with motor onto it ? so i got 2 ibt with motors driving with 1 signal from arduino . doing the same motion ? did find out with my 4 dof construction i can go/get surging movement because the balljoin construction ,not much , but stil the movement from the balljoint free play . so i wanted to ad 2 motors to the back from the triangel motion box i did make , the back is where the most weight is , and using 2 motors for 1 motion..im seeing lots of motion designs with having gas stud for holding up the weight ore maybe for reducing the ..slack .. with planetarie i got almost no slack ... i got now rol / pitch , heaving , yawing and some surging . the yawing is great , better then i thought , the yaw motion slide is not long i thought , but seeing in real and test it with sitting onto the test plateau its lots of movemend .testing the motion normaly , ibt about 27 graden c . wile i,m reading there getting hot and burn/explode ? a 15 amp fuse wil hold with normaly motion 5 kg weight . the 10 amp wil burn with some heavy motion . 20 amp fuse now and 21 amp psu now .

i know i would fall into this problem , but got 2 egual motors and 2x ibt , same power source , gone give it a try next week , maybe fine tuning with some little/minimum fighting against is acceptable ..will then not using the u shape bridge to seat that is onto it now , but separate support beams/legs to the seat just for the back connection .

problem 1 : got differend pot meters , differend brand name . 1 x 10 k 15% and 1x 10k 5%. the 5 % i did test . working in smc3 for using axis 3 and 4 with 2 arduinos ... arduino 1 for using axis 1 and 2 ,15% pot . arduino 2 axis 3 and 4 with the 5 % ,, but 10 times slower than the 15 % ? can i adjust this in smc3 settings ? already did order 3x the 15 % because they are working correct for my setup , fast moving and response . the 5% is verry verry slow .... the 15%

the 5 %

update: got the motion working , did test lfs , works for now with 2 dof . got the parts and convert it to 4 dof this weekend .. motors feeling verry strong , lifting up easy ... 15 amp fuse did not go . verry smooth and not loud , motors are wp planetary 90 mm 24v . you only hearing the fan motors from the power psu when in motion with 1 person into the seat . some adjusting need in simtools , but already much fun with playing lfs with motion .. the second motion rig ferrari p4/5 is starting up in a few weeks , got al the parts now .

.stil figuring out why my second uno for 4 dof is not working . the same software onto the card , adressed for 2 motors a1 and a2 setup for arduino nr 2 . com for arduino 2 is visseble and set for interface 2 , but no motion ..got no usb hub , connecting the uno with usb direct to pc usb port , so each uno have his usb cable to pc usb . pc is seeing com 3 and 4 when connecting the 2 usb cabels ..1 arduno is official other is a clone ..clone is uno r3 to interface 2 . blinking test did work ....wiring connection to arduino 2 is same as arduino 1 who is working 2 dof , also a1 and a2 assign to it and works . arduino 1 is for rol/pitch/ that is working now , , arduino 2 is for heave and jaw . after i got arduino 2 working i have to ad arduino 1 a1/a2 heave to it ?

yes smc3 . further testing will take some time now , see my topic .. type error ..

for sale in a second hand store this seat ...... nice for the ferrari project . did do him a offer already .

2 arduinos running now ,, 3dof motion now . interface error was setting axis interface , arduino 1 A<axis1a> for arduino nr 2 it would be A<axis1b> . that was my error , all working now ...did use for both interface arduino 1a , arduino 2 also 1a, would be 1b.... stil learning , but it works ..did test run lfs , , realy nice motion 44 % , bts driver did get heat up to 34c /39c ... 2 x 200n gas struts attach to it now , almost to much lift now . i think 1 gas strut 200n wil do the job .. just some printing job to do and then for 4 dof yaw ....
