Arduino due + CNC Protoneer v3

[WZdunski]

Hi, First of all, thank you for this project.
After uploading, there is an error: 9, 18. I changed $ 14 to 7 and the alarm disappears.
But the problem I am struggling with is connecting the motors. After connecting the Protoneer v3 CNC board, there is always power on the motors control pins. I have implemented every map and this problem is always there.
What should I change to solve this problem?

Thanks for any advice.
