电机不运转，发送的正确值不起作用

Question

我正在尝试使电动机运行，并且代码正在将正确的值发送给电动机，而电动机才刚刚不运行。我认为Movement1变量有问题。电机可以工作是因为我已经用另一个程序对其进行了测试，但是我很确定它与移动1值有关。

ScaleImage = imread('Images/Menu.jpg');
imshow(ScaleImage);

[xClick1,yClick1] = ginput(1)

Movement1 = xClick1

%Peanut butter
if Movement1>14.7 && Movement1<493
Movement1=2.75
end

%Jelly 
if Movement1>500 && Movement1<1000
Movement1=8
end 

%Honey
if Movement1>1123 && Movement1<1495
Movement1=13.75
end

pause(5)

if Movement1 == 2.75
MovementPB = 2 
MovementJ = 0
MovementH = 0
end

if Movement1 == 8
MovementJ = 2
MovementPB = 0
MovementH = 0
end

if Movement1 == 13.75
MovementH = 2
MovementJ = 0
MovementPB = 0
end

try
s = serial('/dev/tty.usbmodem1421')
set(s,'BaudRate',115200)
fopen(s)
pause(2)
fprintf (s, 'G17 G20 G90 G94 G54')
pause(2)
CNCMotion = ['G1 x',num2str(Movement1), 'F10']
pause(2)
CNCMotion = ['G1 y',num2str(MovementJ), 'F10']

pause(2)



fprintf(s,CNCMotion)

catch ME
fclose(s)
ME.message
end
