Diode mm/min vs CO2 mm/sec

Hello hope you are all well.

I have not found the answe, thus my presence here.
Why do we choose these units for the mentionned lasers? Why not have 1 generic unit mm/s? From a diode laser to CO2 laser is it possible to convert the speed values?

You can use any unit of measure you’re comfortable with. Just be aware of the conversions when using others’ designs or reading blogs/posts/discussions.

Is mostly a bit of history
Co2’s were always able to - for the most part - have speeds of operation big enough that would make sense to use mm/sec instead of mm/min
500mm/sec is more convenient to write than 30000mm/min even though they are the same
Also, the granularity needed on co2 is much smaller than in diode machines. 500/501/502 make no diference
500-600-700mm/min in diodes does

Diode lasers were also very under powered by order of magnituedes, something that is less acurate now with diodes being able to output 40W, at first 2.5W was a “LOT of power” for diodes (circa 2018-2020)

So the use of mm/min on diode lasers is more a matter of scale and granularity that is NEEDED and usable on diodes but isnt on CO2 (or fibers)

Also became a industry sort of standard, all communities of diodes speak in mm/min, Co2s in mm/sec.


And, if only the USA would have “gone metric” back in the day, things would be so much simpler!

Nobody would have trouble with a machine set to inch/min when they’re thinking mm/min. Or the other way around. Or, worse, the bizarre option of distances in inches and speeds in `mm/min’.
