Am I doing this right?

RE: Am I doing this right?
If the calibration of the playing surface is perfect, there should not be problems with any blue feature outside the playing "area" but that might be a likely problem if the camera sees any blue-ish object on the playing court beside the robot :-\

Does the robot make the "test pattern" correctly? (there is a video in the assembly guide showing the movements the robot should make.)

Beside all of this.
How much did you reduce the metal bars lenght? There is one thing you will need to modify. It is not related with the lack of movement of the robot, but has to be done: That will increase the accuracy of the robot movements

Inside the configuration.h file, the dimension parameters are set:
Code:
// This is the center of the table. All units in milimeters
// This are the dimensions of the official air hockey table Exploter from Buffalo
#define TABLE_LENGTH 895
#define TABLE_WIDTH 435
#define ROBOT_CENTER_X TABLE_WIDTH/2   // Center of robot.
#define ROBOT_CENTER_Y TABLE_LENGTH/2

// Absolute Min and Max robot positions in mm (measured from center of robot pusher)
#define ROBOT_MIN_X 60
#define ROBOT_MIN_Y 58
#define ROBOT_MAX_X TABLE_WIDTH-ROBOT_MIN_X
#define ROBOT_MAX_Y ROBOT_CENTER_Y-80[/i]

Set the correct dimensions of the new air hockey table.

One last thing: trim the current output of the stepper motor drives using a screwdriver. In the assembly guide there is info about how to do that. There is a small screw on top of the stepper motor drivers, rotate it sligthly in order to get more power from them (just a little bit)

Let us know how it goes!
