i am new to the cnc building a plasma table and had mach 3 set up and running motors in my house tore down the computer cabling to move to shop and now i dont have motor movement that i had in my home .

any help is apreciated to figure out this problem.

i looked in the computer diagnostics area in mach 3 and i dont have the first 3 pins light up in led lights 1,2,3 but 4,5,6,7 are light up , i have no motor movement and the fan is not running on the motor control board. the board has power to it 120 volt and aproximately 3 volts to the output side to motors but I have no motor movement and like stated the fan is not runnung either in the driver boards housing.

i have been building off and on for quite a few years a 5x10 plasma table with gear rack on x & y and zaxis is built by c & cnc .iam thinking maybe the cabling is bad like a pushed pin or something in the printer port cabling any way to check that out?
