I am resurrecting my old MaxNC 15CL. It has been doing well but now having trouble just getting up and going. When jogging any of the axes in the direction of the limit switches I get a servo error. I took my multi meter to that circuit and I have at least one of the limit switches not working as it is permanently in an open position. To verify this, I was able to jog all axes by bypassing the circuit altogether by connecting the 2 pins from the circuit board to each other and everything works fine. I know I can run it this way, but would like the limit switches in place.
Does anyone know of the make/model of the limit switches in these old Maxnc machines? Mine's a 15CL
