Great…
The way a laser module works says you are not correct. Likely that your assumptions are leading you down the wrong path.
A solid state laser module for these hobby machine is directly driven by the pwm, so it’s on when high and off when low.
The way the controller besides on 1/2 power is by the production of a 50% pwm control signal. This turns your laser on for 1/2 the time and off for 1/2 the time. This resolves to 50% power.
If your machine is configured properly, then this is pretty much impossible to do.
What’s more likely is that the material you’re using isn’t responding linearly to the lasers effect.
If it starts to burn at 40%, then turns to charcoal at 60% it’s only linear in a small range.
Knowing this, maybe your conclusions will change?

You’re literally agreeing that my assessment is correct, while ASSUMING that my theory is the laser. It doesn’t matter what the cause is, right? What matters is the results! LOL!
Unfortunately, there is a correlation between knowing the cause and interpreting the results. But that is the real fun in this game. It is never boring!
Those speeds are absolutely insane for such a small print. The laser will never ever reach that speed in such a short space. So your values are not a real test but just arbitrary. It looks like those letters are about 20-40 mm in width, so either you turn on a high overscan or use a maximum speed of 1000-3000 mm/min.
What you are seeing is some arbitrary output based on the acceleration curve that is different in both cases, but you never reach the actual values, as such, it’s just guessing.
In general: cutting speeds are 500-1500 mm/min, engraving speeds are 1000-10k maximum. Everything above is just marketing. Such a heavy laser head cannot move faster, only if you laser a 400 mm line, and then it reaches this speed in the middle part.
Additionally, if you use it for images later, the maximum speed is 7000 mm/min at grayscale, because the serial interface is not faster.

This is super helpful information! I only recently started using the 60W mode, so I assumed that I could go much faster and have been experimenting. I was actually looking for a way to get machine feedback on actual speeds, because I was questioning whether it was actually hitting the programmed speeds.
Thank you!
