X Y Plotter using Arduino Uno

Using Arduino Project Guidance
#1

Hi Everyone,

I'm working on a project to do X Y Plotter. This project basically to reduce the human error to get the right location to plot. Currently we are using a manual X Y roller

I intend to do like | Insert Location X: Insert Location Y: | and this machine will automatically go to that specific location. However, i not really sure how to do it cause wafer is a circle (hand size), and I dont want it to measure out of the circle. Is it like set the codes to not go beyond certain point?

Thank you, hope to hear something :slight_smile:

set the codes to not go beyond certain point?

To plot (x,y) points that fall only within or on a circle of radius R

   if (x*x + y*y <= R*R) plot(x,y);

assuming that the origin of (x,y) is the center of the circle.

It is more complicated if that is not true. If the circle is centered at (x0, y0) then:

   if ((x-x0)*(x-x0) + (y-y0)*(y-y0) <= R*R) plot(x,y);

This gives no useful guidance as to what you want help with.

It may be with mathematics, as @jremington has surmised.

Or it may be with the design of a mechanical device that can move something (what?) to a specific location.

Or you may already have a machine (what machine?) and need help writing a program to control it.

Hi, sorry for not giving specific details.

Yup, my group is designing a X Y Plotter machine that can move X-axis & Y-axis. (my partner already started building). I want this machine to go to specific location for example ( X= 5, Y= 6.5) automatically when i enter this 2 data in a prompt box (if possible).
Example like Arduino Controlled XY T-Slot Table - YouTube . It moves and stops and different location.

No manual button/ analog involved in moving the axis but automatically. Is this possible?

And yes, i need help writing a program to control it. Thank you

Then you need to provide details of the hardware that the Arduino needs to control.

  • Post a link to the datasheet for your stepper motors
  • What stepper drivers are you using
  • What stepper power supply are you using (volts and amps)
  • There will need to be limit switches so the Arduino can tell when the device is at the HOME position.
  • How many steps are required to move 1 mm?

and I’m sure there is a lot more

If you have no programming experience this will be a major challenge.

Even if you are not a beginner, you need to break the project into lots of small pieces. Have a look at Planning and Implementing a Program
