wiring limit switches
« on: November 17, 2014, 05:39:14 PM »
Brief background. I have a bridgeport MDI with servos that I am retrofitting with ESS, c32, dugong drivers, antek 1500w 105v power supply, mach3 obviously. Anyways, I just started putting together the boards and cabinet after a long break from tearing the cabinet apart. I am looking at adding my limit switches, but not sure what is my best option. I am looking at running the estop and limit switches (I will be wiring both the + and - limit switches for each of the three axis) and thought I would use the optoisolated RJ45's on the c32, but it looks like I could only use RJ45 #7 and #11 as RJ45 #8 does not have four available pins to use. Anyways, if I use these, I will need to buy two c27 BOB's to wire them in, OR I could buy a c10 and use the third port on the ESS and have more choices, only problem is, they are not optoisolated, and not sure why both the c27 and c10 need resistors wired in series, would this not negate the advantage of running them on 24vdc compared to an easier 5vdc?

I plan on trying to use the + limit switches also as a home, can this be done easily? thanks in advance!

I have been trying to set up the limit switches but what ever I do I cannot get any response from the switches, they are wired as per the manual, I have motion on all axes but cannot set the limits . I have tried a second BoB and rechecked the wiring as per the manual but cannot get any switch to work . The switches seem to respond when checked with a multimeter,  still not working ,  Have I missed something, misread something or am I just going crazy??
