Shortcuts needed for remote

Hi, I’m building a simple remote for my co2 laser using arduino and an ESP32 board that can emulate a bluetooth keyboard, here is the preliminary layout so far

What I’m missing and from what I read so far, there is no STOP or PAUSE shortcuts due to security reasons.

I think a remote of this type can benefit greatly by having at least a pause button, even better pause and stop buttons.

Is it much of a hassle if I ask for an obscure keyboard combination or even obscurer keyboard escape code for pause and stop that can be only used by a keyboard emulator remote like the one I’m building?

Pretty please with sugar and a cherry on top? :grinning:


What co2 controller do you have?


I have a Ruida 6442 controller on an Aeon Mira7 connected via LB Bridge.

I ran across this app for an Android… Not sure if it works with the bridge or at all… Use at your own risk… I got it off the android apps from Google…


The ruida remote is not what I have in mind, I’m emulating a keyboard keystroke but wirelessly, its like having a second keyboard attached to the computer running LB.

Please dev team!!

Today I made the frame for the switches. Then wiring and finally coding. Still hoping to get these missing scan codes!

I’m not sure what you are looking for here. I would think it would be different for a Mac, Windows or Linux.

If you get the ‘codes’, how do you ‘inject’ this codes into Lightburn?


Its easy, I’m just emulating a bluetooth keyboard, so I send the appropiate shortcut and that’s it.

If you hoover over the buttons some of them show the shortcut, but, PAUSE and STOP have none

That seems to simplify it quite a bit. Maybe you should post questioning what those specific ones are.

There is also Feature Suggestions that will allow you to post a request and the users vote on it. I’d love to be able to pulse my laser when I’m at the back opposite corner adjusting a mirror…


Before posting this I read previous posts about this same thing, shortcuts for STOP, and there were always concerns regarding safety. Thats why I ask for keyboard codes that cannot be easily entered on a regular keyboard
That would eliminate the concerns and keep the benefits.

slowly advancing during the weekend, I have all the keys ready for breadboarding…!

All the addressable keypresses are working! at least using a Keyboard Event Viewer, tomorrow I will be able to test them live.

image shows working Alt-Shift-Z (focus) and Alt-S (start)

I’m still wishing for stop/pause keycodes

so anxious to test it…


it works!!

This would be faaar better with an API, but for the time being, I have no better idea on how to implement a remote.
