d max project

Hi to all guys
im ready to order all my staff ..please if someone could chek if all is right for start the war ahhaha
1 - elettrocookie uno
3 Sensore, Hall, 0,2 V, 20 V a -10 V, PIN,
3 HiLetgo BTS7960 43A Dual H-Bridge Stepper Motor Drive Curr
2 24V 25A 600W 110/220VAC-DC24V Adattatore Trasformato
1 arduino rev 3
2 pc fan
1 box for electric wire
3 motor i decide to take from au is just difficult project for me i f i complicate more changing something from the step by step video im sure something 'll go bad so... ttp://www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html
, they sell them in 12 or 24 volt wich one i've to buy ?? 12 0r 24 ?
also they can put a shaft inside so i dont have to make modification in the hole motor like max and they say: (Please note that the shaft we supply is not a TIGHT fit. There is approximately a 0.3mm tolerance between the internal tube and the shaft.
If you want the shaft to be a little extra snug, you need it to be ~12.3mm!) best choice for the project ?
thank you very much and sorry for the begginners questions

I found it on alibaba ...all the other staff are right for start ?or im missing something ?
Last question the motor are 24 volt and im not sure for that motor gear ratio 1:25 or 1:50 they can supply in two option im ordering from china i wanna buy the right one
Thanks

Here the motor

Hello, the motors seem to be fine, the sensors use 0-5v, I also buy in China, I am from Spain, for me the cheapest option is AliExpress, I will post a photo with the material that has worked well for me

I say on the title the frame and project is the same of d max so 2 gear front and 1 on rear for traction loss ..so is 1 :50 finally ?
With the simulator calc i lost myself it make me more confusion im too begonner for use it naw and at this momdnt i dont have the frame i'll proced like d max with his measure fig go myself but thd same frame dimension etc so ll be easear
sorry and thanks

thanks you very much ...naw the nightmare/dream can start
ahahha

Finally ...after about 3 day of speaking with all the world , my china man is missed ...aahahahahah i decide to buy this like Antonio

Sorry guy i was reading the sim tools guide and all the staff, im missing one point because im too beginner
He say the interfaccia depend on the hardware...
I use arduino and dc motor wich one i need to chose as platform in this guide photo ?
Thanks

So. I think is a plugin to have only if you use other type ...?i m reading a lot of all the post in this forum and is my furst week approaching ....
So is a plugin that i dont need ...?

Sorry guy im missing myself , and i dont wanna stop during setup
in that point n3 of the sim tool guide he say that the interface i use depend on the hardware i use for to control the simulator once installed ...
What does it mean ( in the picture there are ...Serial, memory map...etc) i ve to choose one of that or anyone ? Wich is mine ?
Oh my god ....aahah give me some helps

Tank you beast ...i can sleep quite tonaight

I upload some progresss ...

Sorry guys ...ive a dubt
For my first profile it say i must run live for speed before ....but I must run live for speed in demo mode also if I never'll play with that game ? Or i can make a profile on acc directly?
Or i must do a profile on live fof speed and after i'll use that profile as base profile for acc ?
Thanks .

Ok thank you very much
