set up google voice, you will be able to disconnect it and provide it here I will call you and provide you explanations and routes.
After I did research on your set up it is not even what I was expecting, not 50um it is 270um -380um, depending what/which lens you have, just horrible.
Scan Lenses, f-theta lenses for CO2 Lasers
this is why you have a problem.The hybrid you have - lens is the problem.
Keyence lens F0 theta for field 300mm x 300mm 5um is 1000.00 alone.
what is your google voice number or email me to keyencelasers gmail
Kind Regards.
