Advice needed regarding cutting and engraving

[shadowfang]

Hi everyone, this is my first time posting here. Hope you are all safe and well.

I work at a design agency and amongst all our equipment we have a hpc laser cutter that I have been trying to get going. We moved premises and I was given the task of getting it all set up again.

I have everything set up and ready to go, done some test files but having problems with inconsistent engraving and cutting results across the bed.

I have attached pictures of the results here:






Do you think this could be a mirror alignment issue? It seems as if the engraving changes strength across the bed of the machine?

Any help would be great?

Thanks
Matt

Yes - typical issue when bed is not level of mirrors out. Check bed is level with the ruler tool in each corner of the bed first then move to the mirrors.
