Hi all I'm new here,
I just assembled the machine in the title, I'm not sure about the limit switches wiring (3 pins from the switch, two pole from the cable, red and black), anyway I installed mach3 following the instructions from the seller and I plugged the machine on the computer with its usb cable but the machine doesn't move at all and mach3 sais that cnc is not connected, I took a photo of the control board maybe it helps.
