Laser machine got slower

[aritaliang]

I was using the same speed and the same power, but then it slows down a lot, but i dont know the reason, what reason can it be?

Without any further information, this can be anything. Maybe you have been simply drunk (no offense )
Show the project, the speed settings, the result, the laser model, settings used…

Hi Misken,
thank you for your reply, I was using my laser cut machine to cut the polywood in 3mm and with the suggested speed power and pass, but then the machine just no more able to cut it through as from the beginning
for my laser the suggested speed is 350, 100 power with 1 pass.

So not the machine slows down, but it doesn’t cut as well as before? Did you clean the lens regularly? Using the diode at 100% constantly will also decrease lifetime.
