Problem whit pololu jrk 21v3 and converter

[motiondave]

O mi god.
So if i keap that mi simulator it is ready!!!!
A little plastic object!!!
Ahahahahaha
Tanck you my friend...
You are mi angel.
I think that now i ave understood.
Sorry last question.
Pololu jrk 12v12 support 30a?
Or it dead if i use tath power?!!!??
Ahahaha

30 amps continuous all day with heat sink and cooling, and 40 amps peaks
I run my big motors with 2 x 40 amps power supplies for extra power when heeded, but as yoko says, a car battery and 20 amp or more power supply or a car charger in parallel will do the job as well.
Big motors depending on intensity of motion and power settings in utility can draw 32 amps each average at full power or about 22-25 amps each with better power settings and still get great motion.

Motiondave the pot have somthing that i have to do?
It is dangerous if i do a diy pot!?
It is only for stop the wiper motors course?
Tank you mi friend
Best regard

Yes the pot setup is neeeded or you will have no feedback for the control board.
DIY pot is fine, 5kohm or 10khohm single turn will do nicely, refer to the pictures I sent you.
You dont need gears as a start, just use a cut out lever like I have done. It may only go 90-120 deg, but thats enough to get you moving.
You can look at gears and multiturn pots later once you get a better understanding of how a feedback pot works.
Once the pot is fitted to the lever arm , if the motor lever goes too far, the motor will stop, feedback disconnect.

Please!!!!
Someone can explain me how and what do I do with the potentiometers.
I have to change them? someone can 'tell me what to do?
I'm 'going crazy
It is simple but i do not understand!!!!
or, someone wants to prepare two potentiometers?
I need two pots that do move through an angle of 90 degrees to the two wiper motors
PLEASE HELP!!!!

Hi, you have to connect the three pins as described in the manual. One to pin GND, one to 5Volt and one to the analogue input.
You see the pot position inside the pololu software. Your pot has a bigger angle, no problem.
For the first run you move your rig manual to max postion and set your pololu to that value, same with the minimum. 90° will be scaled for you.

Some days later you might exchange this pots for 90° pots like described in the open source arduino post.

Ok Sir tomorrow i think received a new pots and i can try.
Intime i have search in google and i have see tath.

Change the direction pins or the 5V + GND on your pot.
Make a wiring schematic (on paper and scan it)
