Laser power low

(Michiel Vrolix) #1

Machine: generic Chinese Lasercutter

Board: cohesion 3D laser board

Firmware: Smoothie

Problem/ Question: When the laser is powered, the laser power is way lower than usual. I’ve read somewhere else on this forum that this could be due to the LPSU not being able to work with the pwm. However this is not the case because the previous controller (an arduino running GRBL) used to pwm the LPSU withouth any problems.
The name of the LPSU is HY-T150.

I tried to upload the config file but couldn’t since I’m a new user.

Hi Michiel.

Take a look at this and let me know if it helps. Sometimes the frequency needs changed.
