Lightburn recognizing correct files

LightBurn Software Questions
1

Hi there,
I am a laser machine supplier. My client have a very high requirement on the accuracy. They have about 16 Galvo laser on earth. They need all lasers under their system follow the same home position. Ultimately, any lasers can be swap within their system but no further finetuned is not needed. To do so, I have developed a procedure to synchronized all machines:

  1. Print a grid line image by the master machine.
  2. Coat the etched image by a red pen and this is already the benchmark plate.
  3. etch the same image by the fellow machines.
  4. keep finetuning the correct file until the image is perfectly overlapped on the master. Normally we can make thew artwork fully overlapped by fellow machines. We say this is perfectly aligned.

However, some factories reported the grid line is suddenly not aligned. Then we need to finetune the correct again. but it will change sometimes again.
Till now i cannot figure out the pattern of the changing size nor if this is a hardware or software problem. Does any one has seen any similar case before?

Never seen that before but…
From what I could understand, to know if the problem comes from the software, it will be enough to analyze the changes that exist in the file. If there are no changes to the file, and considering that the problem is sporadic on some machines, I’d point to a problem in the machines.

Hi Kuth,
Thank you for your reply.
if we think the problem comes from the machine, would you think that is from the scanner? Thanks

Peter,
I don’t know exactly. I’m just trying to point out where the problem might be.
As I mentioned, I’ve never experienced the same issue nor do I work with this type of laser machine.
I drew an analogy to the problem and indicated what seems most logical to me.
I don’t feel comfortable giving more specific guidance because I risk pointing in the wrong direction.
I hope you understand! :+1:

I assume these are fiber machines? Galvo can be attached to other lasers also.

Are these standard type fiber galvo machines with all the same configuration between all of them?

Many of these, especially with longer lenses don’t seem that the Z adjustment is actually super accurate. I’ve seen a bunch of these that the head isn’t mounted securely to the piece that moves up/down.

Any variation of the head position will effect the burn area.
