There's lots of different ways of making a Polargraph machine. You will get better help if you can describe your machine.

Describe:
What kind of microcontroller you have (eg arduino UNO / MEGA)
What kind of motor driver you have (eg Adafruit Motor shield v1, Adafruit motor shield v2, Polarshield)
Which firmware you're using (where you got it from, what version)
Which controller you're using (where you got it from, what version)

It might also be helpful to mention what your motors are like (steps per revolution or step size).

Tell us what you have done (step by step).
What you expected to happen.
What actually happened.

Start a new thread for your troubleshooting session, and continue that thread until you have got a working machine. Each time you solve a part of your problem, update the thread so other people can benefit from your experience. This helps us know that we are helping too!

Hello
I start to build a polargraph with a arduino uno and l293d driver with a clone of adafruit motorshield v1, the firmware and controles are the last versión, I follow the steps from many places. The problem is when the polargraph starts to work after some lines arduino disconnect and the controller appearrs busy and if I check the conexión dissaper the com3 that is when arduino is conectted. I Was using a 12 volts a 2 amps and i check with 2 different usb cables. If i disconnect the motorshield arduino uno works properly.

Thanks and sorry for my English

Pd. I didmt find where is the new threat, for that o wrote here, sorry again

Hi this sounds like it might be a power supply issue. Does the Arduino restart?

When the motors start moving, they often draw a lot of current, which sometimes starves the microprocessor of power and causes it to reset. That could be if you haven't separated the motor power supply from the arduino power supply.

Your power supply seems like it would be powerful enough though.

Alternatively the L293Ds may be overheating and that can cause a reset. You will be able to feel the heat if this is the case.

This is obviously not a problem with the arduino or with the firmware since it runs ok on it's own. There could be a fault on the motorshield. Other things you might try to narrow it down.

Disconnect a motor or remove a L293D - disconnect both motors or L293Ds
Disconnect the 12v power supply. Do the motors run at all?
