setting up EMERGENCY STOP button on GRBL arduino CNC machinery (3 methods)

Industrial equipment needs to have a fast, safe method to turn the machine off if something goes wrong. GRBL is becoming a very popular method of controlling CNC milling machines and a multitude of other types of computer number-controlled devices. In this video I show three methods to wire up a safety stop with an Arduino.

Awesome video. My 3018 is just a kit, so I was just trying to figure out which connector on the board the stop switch was supposed to plug into. So this was way more depth than I needed, but it helped greatly with my understanding of what's going on. I plugged it into "reset" and it works great. Thanks!

thanks for the video. i’m in the process of installing an e-stop to my ox cnc using arduino and from what i saw one input goes to Analog-0 according to the grbl diagram and the other end goes to a ground pin? thanks i wasn’t able to see which pin you connected the other wire & i do notice that on uno board and mega the first analog pin changes but is the mega worth getting for grbl if i already use the uno? i know that the uno board is maxed out with the grbl code & theres no room for extra features

i have i what i think they call the woodpecker or camxtool v3.5 grbl board so its one of the smaller all in one boards that have the stepper drivers built into the board. i just got the board about 2 weeks ago an ive had the machine for about 2 yrs but had mainly used it with a laser so never used the z axis due to the laser having a focusable lens so when i started back with the spindle i found it dead an got a new control board an decided it was better to have a emergency stop switch than to try to fumble for the abort button on a laptop but is all i have to do is plug it up into the stop port on the grbl board an i dont have to do anything in the setting or firmware or gcode? this not what im used to. im coming from dealing with 3d printer an if u add a new sensor or enstop or pretty much any change to the machine u have to do something in the firmware to make it work properly. only thing i can think of that u can do without a firmware update is changing the hotend an that still requires pid tune an saving the new settings an that can be a pain with a board without eprom enable and adding cooling u dont have to do anything other than that but for anything else u have to make changes either in the firmware or settings. theres alot more differences than i had thought until i started trying to use the router more.

Hi,
Thanks a lot, its really greate effort and great knowledge.
i need to do a project for a preset position linear actuator with a DC motor abd a stepper motor, with Arduino Mega or UNO but i am not able to write the code and the scheme, can you please help.
Regards

Hello. What software are you using? Is browser based?

[@mberglof]

That would be CNCjs, github.com/cncjs/cncjs

cncjs i think
