Question about scaling up

I notice that in the configuration.h file the following lines:

// Robot
#define ROBOT_MIN_X 0
#define ROBOT_MIN_Y 0
#define ROBOT_MAX_X 358
#define ROBOT_MAX_Y 123

If I wanted to scale this robot up, say to a 45″ by 36″ whiteboard, would I only need to change the MAX_X and MAX_Y values to match the new board?

How would I scale svgs and other drawings up to the size of the larger board? Would that require further modification inside of the app? I would probably be using the offline app posted on this forum for an offline mode for the final application.

The “cloud” service will send the same movement commands to the iboardbot and the robot, locally (via Arduino code) will have to re-scale everything to the new dimensions. I mean, the motors will have to move X times applying the new SCALEFACTOR you have chosen.
So, you can leave those ROBOT_MIN and MAX parameters as they are and re-scale the motor movements the required proportions. Of course, you will reduce the resolution accordingly.
