!need Help CNC6040Z USB Limit switch wiring!

[john swift]

as Clive said
wire N/C switches in series

it should be the safer option as the machine will stop if a wire breaks
as this is more likely than a two core cable being short circuited
(although it could happen if a cable is crushed)

the last diagram of post 11 is for 1 axis ,
you will need three pairs of N/C switches for the 3 axis

as mach 3 only homes 1 axis at a time you could connect all 6 switches in series and use just 1 input

Hi there John but your drawing has com and NO pin connected and mine is NC and COM pin on mini limit switches...
check my pic of 2 switches for one axis in series connected and tell me if I have wired it correctly???

Then which one of the COM or NC(NO) is GND or +5V and which one signal???

also Can I use all ground connections from that free connector on the right side of the board near 24V that says::--->> C NO 0-10V GND-<<<---?????
on this pic??????

I'm confused

Where does it say that John shows com and NO? Do you have a multi meter? I suggest you read the post again. As the drawing clearly shows you the way it is wired.
With a multi meter is is very easy to check you have it OK. You can also check if the two grounds ie the 5V one and the one you referred to are indeed connected together. If you are not sure use the 5v ground

now I have seen the photo of your micro switch
I can see why you are confused

on my diagram the N/C contact is shown as the centre terminal
and on your switches the N/C terminal is at the opposite end to the common



John

PS
I can not find any details of the board to tell if the unused GND
terminal can be used as an additional Ground / common for your switches



you will have to check for continuiy with the switch common terminal

or use an additional terminal block to connect all the common switch wires together to a single wire from the switch common terminal

Hi,there Clive I was saying that Johns pic of two limit switches in Normally Closed connection at the top of this page looked different to my limit switches in NC connection. that's all I guess the the limit switches were different, but thank you both for being patient and very supportive,as I wouldn't even get this far.:)

Now My machine is a cnc6040Z USB 3 axis and I would like to know how and what I need to select from Step 1: of the installing of Mach 3.exe :::of this pic


And then from Step 2: after installation on this pic---->

ect ect..thank you sorry to be a pain but i'm learning allot from you guys :))

Hi I suggest you read through the various manuals and installation vids first.

[john swift]

assuming you have the USB motion controllers "plug in " installed so Mach3 works via the USB connection

to add the probe you will need to go into mach 3 ports & pins
and select input signals


about halfway down you will find the probe

Hi there john I managed to get a few things setup.
what I found out was that in order for mach 3 to run on my laptop it needed to have Parallel Port checkbox ticked on initial installation and now it shows in Diagnostics tab :: pulse and other processors incrementing and decrementing which watching the you tube video shows thats what I need to see ,also I did a Driver Test on my Laptop and it said Excellent in green and all stable.so all that is good. So I proceeded forward to the Motor outputs tab and looked at the pdf they sent for my machine and set the Step pin and Dir pin according to the pdf spec pinout ,so I need to know what else needs to be checked on the motor output tab.I also want Mach 3 to control spindle automatically do I need to check that and anything else on that page and also on the Input signals tab what needs to be ticked for all limit switches and homing to work having trouble with that not working???????Please help thank you
