 for i=1:11
      tar_point=['X',num2str(pos(i,1)),' Y',num2str(pos(i,2)),' Z',num2str(pos(i,3))]; 
      comd1=['G01 F200 ',tar_point]; 
      writeline(s,'M03 on') ;
      writeline(s,comd1);
      pause(1.0);
      writeline(s,'M05 off') ;
  end  
%Each mark point is in the pos variable.

Hi Matthew,

I understand that you would like to loop over for 324-mark positions.

You can update the code by replacing "for i = 1:11" with "for i = 1:324"; this change ensures the loop encompasses all 324 mark positions and the rest of the code remains the same.

You can refer to the updated code below:

for i = 1:324
    % Create a G-code command for the target point
    tar_point = ['X', num2str(pos(i, 1)), ' Y', num2str(pos(i, 2)), ' Z', num2str(pos(i, 3))];
    comd1 = ['G01 F200 ', tar_point];
    
    % Send commands to turn on the valve (M03), move to the target point, and turn off the valve (M05)
    writeline(s, 'M03 on');
    writeline(s, comd1);
    pause(1.0);  % Pause for 1 second (adjust as needed)
    writeline(s, 'M05 off');
end
