I think the sensor cable I'm using now for my mill project is 22ga 4 conductor shielded.. But don't know what the gage is for the motor drive 2 conductor shielded cable. I don't think the size of the sensor cables is so important seeing they don't carry much load but.....
Also was wondering if the motor drive cables should go to a larger gage seeing for the 4x8 the length would be longer then on the mill and driving the larger 1100oz motor.
Any suggestions there would help. I know there was a thread on cables here although I don't think they were talking about motor drive cable sizes..
