Hello, I want to make a cnc shield grbl supported laser diode machine. I have encountered some errors. I can upload the grbl software to arduino and manually make the x and y movements of the machine without any problems. However, when I try to run the cam program, I get the errors in the attachment after 5-6 lines. Also, when I try to connect the endstop switches to the machine, the machine does not see the switches. Can you help me on how to connect them?
