Hi, I have recently purchased this machine from Amazon - OMTech 60W CO2 Laser Engraver with LightBurn and Water Chiller, 16"x24" Laser Engraving Cutting Machine. I am using LightBurn Pro 2.0.01 on an HP Windows 11 system. Laser is using Ruida. The issue I am having is: I typed the text in my LightBurn grid, but my output position is not corresponding to where I positioned it on the grid in LightBurn. Basically, where I am seeing my job on screen is not matching where the laser is firing.
It’s likely because you have start from in the laser window set to something other than absolute coordinates. Change it to that value in the laser window. It should end up where you have it in your work area.
I commonly have user origin set as I place the head then press origin on the Ruida keyboard.
I also have my return position in the Ruida set to origin.
Make sense?
Review the documentation on the coordinate system.
I have matched your settings (see attached) however my screen bed size is not corresponding to the actual machine bed size. Approximately 3 inches of the entire top is not being recognised. My bed is 600mm x 400mm but it seems as the lightburn is moving everything to fit within 600mm x 324mm
Are you using Absolute Coords? Do you have a workspace offset entered into the Ruida?
I am using Absolute Coords. How can I check if a workspace offset is entered?
You need a Ruida user to get that answer. Pretty sure one will jump in.

This is where the Ruida knows it’s work area size.
Lightburn also has to be told when you configure the device. That’s done when you create the device.
You can also check it in
I’m not sure what you mean here. If you don’t want it keyed to your work area you can set the origin and that offsets the artwork…?
That’s a concept applying to decendants of GRBL / CNC family. Ruida controllers don’t have any of that, because they’re not CNC machines.
For a Ruida controller:
- The home switches set the machine origin
- The
Machine Travel Limitsset the platform size - Then the LightBurn
Workspace Areamust match that those values
All machine home to 0, 0 for an origin, what this does do is identify the quadrant of operation.
I think if you press the origin button and use that, you’re applying an offset from origin.
If these are not computer numerical control (CNC) machines then do you believe they are not computers or they don’t use numerical control ?
How would you classify them?
My wife’s Subaru is a cnc machine, there is no steering shaft, just an encoder and the computer turns the wheels… perfect example of a cnc machine… also does a bunch of other stuff, along with beeps too much. 
ok I figured out my error which was I was confusing the honeycomb bed size which is smaller with my actual bed size 400x600mm, i do apologize

No problem 
You’re right …
I’m biased by thinking of CNC in the context of multi-axis general-purpose machine tools capable of making anything, rather than 2D gadgets tied to specific software that cuts flat stuff.
But, yeah, computer control is computer control.

My electric tooth brush is a cnc machine … it has a micro controller… as does the coffee pot.
Most everything runs on some type of computer or controller. Discrete electronics would be large and not cost effective for home computing or most commercial products.
We saw that with computers made up of vacuum tubes, then ttl… technology marches on although, at that time, a bit expensive for the home.
I guess it’s in the mind of the beholder and coupled with time.
