This is going to be tricky to not have a local computer attached. Some options.
- I believe the X20 has an off-line mode where you can run gcode from USB flash drive. You could save the gcode from your office LightBurn install, save to USB, and run from X20
- It looks like X20 has a wifi interface. If the wifi interface is available in GRBL mode you might be able to connect LightBurn through wifi to your laser. I do now know Atomstack’s implementation and haven’t heard of anyone using wifi on GRBL lasers to successfully do this but the ability to interface through IP was introduced recently. However, it would be deeply impractical, and potentially unsafe, to try to remotely control your laser as you’d need to be going back and forth quite a bit. You could potentially try to remotely control your computer from your phone/tablet while your computer is remotely controlling your laser. See here for some background on this:
How dou You connect Lightburn to DI via wifi? - #3 by berainlb - I believe Atomstack have a mobile APP that connects through wifi to the laser. I don’t know if there’s a feature to run gcode but if so, you could potentially save to gcode from your computer and run from your phone.
For your case I suspect option 1 or getting a cheap dedicated computer would be your best bet.
