!need Help CNC6040Z USB Limit switch wiring!

[Schematicsman]

hi i have managed to upload my cnc6040Z XML settings file that came with the cd for my machine.great i hope you can help me with everything from start to milling something.

i have also attached a pic of the actual limit switches i would like wire in series 2 per axis on the actual board....
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
<<<Now i know that 2 limit switches will have 2 wires coming from them ---->1) Com(black wire GND) /// 2) NC(Red wire)
so that is 6 wires /6 limit switches...>>>
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
now how and where on my jp-3163B v3.9 board i have attached a pic of , will 3 black wires and the 3 red wires be plugged in exactly ???

Also do i have use resisters with my limit switches or not i need full explanation i hope not ?????/??

Sorry for my persistence and rambling. :)

This is how I would connect the limit switches.

I see Eddycurrent beet me to it

while I was adding to one of your pictures


with only the link to select either the internal +5v or an external positive suppy for the input opto isolators
but no link to break the ground connection

it looks like you can not take full advantage of the input
opto-isolators

as soon as I can I will down load mach3 to see what the XML file setting are

Hi,there john hows things,have managed to figure out how to wire up my board, I'm stuck cant get to use my machine I need help on how to wire up 2 limits per axis for my board in the most simplest way and also do i need resisters and what value . basically I need a complete instruction on wiring limit switches on the board specified above???? then exact Mach 3 XML setup to get my machine moving quick and start pcb isolation milling and aluminum milling,Please HeLP ASAP its frustrating me the whole thing is catching dust....

You have the user name "Schematicsman", you are going to mill a pcb, and yet you can't wire two switches in series ? plus you can't read the previous two posts ! having a laugh ?

Hi john I would like to know How to wire 2 limits so when either one
Is pressed that axis stopes??? Which one Normally Opened
or Normaly Closed??? Can I use the ground from the pic I upload of my board that has that single black
Wire ??? Or does it need to come from what you have on your drawing???

hi there John for starters that is just a user name i came up with, has nothing to do with anything and im a newbie in all of this wiring and cnc stuff.so im trying to learn how to wire everything up and properly setup Mach 3 like everybody else to start doing some milling ect.and I need to know,do i need to use resisters and also how do I wire all coms together and fit the wires in the connector???? :(

Hi Schematicsman

if you have the jumper J1 set for using the boards +5V supply
you don't need to add any resistors - that's why I removed them from the original diagram

as to how you physically wire the switches it depends on what connectors you have fitted to the control box


very often you find "aviation" connectors are used on Chinese control boxes
the boxes having a number of holes for 4 limit switches and a probe
blanked off by a paper label when the connectors have not been installed

a photo of your box will help

if you fit four 2 pin connectors
then one pin on each connector is connected to the common ground
then printer port pins 10 ,11, 12, 13 can be connected to the remaining connector terminals
pin 15 can go to your E-stop switch

I will add more later when I return home

John

PS

this is the typical connectors found on Chinese control boxes
note – the danger of mains voltage on chassis mounting plugs !!!


from other posts
some other DIY options that have been used are
either pass the limit switch cable through a strain relief or
used a terminal block fastened to the box






once I know what you have and what method you want to use
either wire the limit switches directly to the breakout board or go via connectors mounted on the box
I will add more diagrams of the wiring

[B]hi i have managed to upload my cnc6040Z XML settings file that came with the cd for my machine.great i hope you can help me with everything from start to milling something.

That is not a MACH3 xml file, a simple check is to search the file in the text editor you are viewing it with, if "Mach3" doesn't appear multiple times in the file then it is not a Mach3 XML file.
