how do I fix power issues with Vevor 80w laser running latest version of Lightburn Pro on an IMac
You need to explain a little more, what kind of power problems, related to LB are you experiencing?
In your profile it says grbl as the controller for your 80Watt CO2 laser, is that correct?

please forgive my ignorance, I have read in so many post about the s-value sometimes needing to be changed in order to get the full power of you r machine . I could not find what mine was and where i can find that value. I use Lightburn 2.0.08 pro i believe (I am away from my other PC). sometimes when I run the machine at 45 percent power 25 speed in an attempt to cut 5mm birch at times it will not cut through cleanly.
After how many hours of use should the machines mirrors be recalibrated and cleaned just curious my laser is only a month old but gonna do it anyway
This does not apply to your C02 laser. It is for GRBL based Diode lasers (and possibly some others)
Did you do it when you first got it? Many lasers are not calibrated correctly at the factory, or things moved during shipping. I would definitely check the mirror adjustment. As far as cleaning, do a visual inspection and clean as necessary. The time between cleanings is a direct result of what materials you’re working with, the amount and type of smoke produced and airflow / exhaust of your machine
In addition to what @thelmuth writes, it is worth noting that exterior plywood can easily be a challenge even for 80Watt machines.
If it is interior glued plywood, you need to find the fault in your optics/focus.
Thank you all for the advice. I began in detail to clean the machine thinking this may have been the cause of the inconsistency, as I took apart the focal lens housing for cleaning I noticed my issue. I had a cracked focal lens. I should have checked this before posting as I had a similar issue with xtool 20w. now just waiting on Amazon.
Does anyone have any recommendations as far as focal lenses go CVD or PVD?
You don’t have to apologize, it’s relatively rare for the lens to break and many others including myself wouldn’t have thought of the lens as the No. 1 problem either. Good that you figured it out.
Sorry, I don’t know what CVD or PVD means.
You should pick your lens depending on the operation. Something that is thicker needs a longer lens so the depth of focus (dof) will allow it to be in focus for the entire operation. A shorter lens for higher detail.
You want the material to lie within the dof of the lens. Meaning you need to focus 1/2 way though the material.
