Hi All,
Just finishing off my cnc controller. I need to install an emergency stop button. Can anyone tell me which wires I connect to the button? Is it the power supply wires? If so, and if I need to stop, that will basically shut off the controller unit. Is that correct?
Thanks.
Alex
As I understand it you need to wire the e-stop through your controller and software to prevent damage by simply cutting the power, and also wire it up for your spindle to stop it rotating.
It might help if you tell people what controller and software are you using?
Unfortunately I don't think I personally will be able to offer much advice.
are you using mach?i wired my E-stop to the software,this stops without loosing position and having to repickup,ive never had a problem doing it this way so far,usually with mach pin 12 is for estop,one wire goes to pin 12 and the other goes to ground on,usually pin 18-25 on the breakout board,let me know what software?ill let you know,some people use estop to cut the motor ,but on some boards,like xylotex,that can blow the board
do you have n estop button already?
one problem with shutting off the power supply is i think the program will keep running,so you would have to reset everything and pickup,using software estop stops all motion and when reset you can keep position,unless you crashed it,then pickup anyway,if needed you can always flip the switch on the controller for the power off,i myself prefer a hand help E-stop for quick response while starting off with a program
Hi all,
I am such a fool. There is an e-stop connection on my breakout board.

But how do I connect the wires? It says pin 10 and pin 5V.
Yes, I just bought an e-stop button. I was thinking it wasn't such a good idea to connect to the power line. So anyone can explain how I can connect it up?
Thanks.
I am using Keling KL5056 driver and CNC4PC breakout board.Originally Posted by thkoutsidthebox
im not sure about that breakout board,never seen one like that,looks like pin 10 is a ground,it color green,and the other is 5v red,for positive,does the instructions say anything about it?did you get it from keling with the drivers?
let me know.you could try one wire from the estop to pin 12 the other wire of the estop to ground normally open,when depressed it grounds pin 12 and signals mach for estop,you are using mach2 or 3?
Hi Sor,
Thanks for the info. I tried connecting one wire to pin 10 and another to the 5V. Nothing happened when I depressed the button. I am using mach2 demo for now. Mach3 runs funny on my other pc. I am not sure what pin 12 is so I don't dare to connect them up that way. Only what is shown on the drawing.\
Yes, the drawing is from Keling site. Th e breakout board is from cnc4pc.com. I think I will write both of them an email regarding this. Once I know, I will post the result.
There aren't any instruction with the kit. Its simple enough once you get down to studying the whole setup. But little things like the home and limit switches and e-stop aren't explained.
You will need to configure the input in the software.
Refer to 'Parallel input setup' on page 5-8 of the MAch2 manual.
Looking at the piece of paper you attached earlier I would say you are correct in connecting it between pin 10 and 5V.

pin 12 is just pin 12 on the breakout board,mach2 is default set for pin 12 on the estop,try to use 10 and 5v,one wire from the estop to each,when depressed should send signal up pin 10,but change the setting in mach estop to be pin 10,than try it
remember mach2 is defualted for pin12,so nothing happens until you change to pin 10 in the software
