Lens Calibration Issue

Hello. I am trying to calibrate a 220 lens for a SFX 60W fiber laser. The lens came with the laser, however, the dimensions were a bit off, and I wanted to fix this. I am able to get a square of 215x215mm (centered) marked correctly, however, once I try to mark a 100x100mm square (also centered) this square measures 98.4x98.4mm. And once I scale this the 215mm square is off. Is there something I am missing or should try? Thank you!


You may have already completed this step.
Next to The galvo 1 and galvo 2 axis right of the scale you will see a . in a box
if you click on the box it will ope a scale correction process.

Do this for both axis and then test your output.

I do not see a video on youtube or lightburn explaining this part of the procedure.
Hope this may help

Tony, thanks for the response! I have used this pop out to adjust the x and y axis and it is very helpful. Unfortunately, it has not solved the issue.
