Laser module won't switch to Precise mode just stays in Normal mode

Creality Falcon

When I press the button on the laser head it won’t switch into the 22w precision mode. I have to cut/engrave everything at the full 40w setting and I don’t need that all the time. Has anyone else experienced the same?

You need to press the button for 3-4 seconds for it to change.

Thank you. I have tried that and no matter how long I hold it down it does not switch the modes. I don’t know if the button has gone bad. I have updated the firmware, taken the laser module apart and cleaned it out well but it still doesn’t respond.

I’m suffering the exact same problem although I’m also having an issue that when I switch the M/C on it automatically goes into Alarm mode so I reset then have to reconnect to laptop / Lightburn - as when reset it loses connection- and have to manually select COMS4 rather than Auto how it normally would connect :man_shrugging::man_facepalming: - HELP PLEASE
