MA staying around 12-14

#1 · May 5, 2020, 1:57 pm

I changed out the standard K40 board to the Mini Gerbil and no matter what percentage I put the settings at it always puts out 12-14ma, even at only 1%. I followed the video for installing it and have all the default settings setup for this site but it still doesn't adjust the power with the percentage I set in Lightburn.

Any help would be greatly appreciated.

usually a loose PWM wire or bad connection causes this issue. Check the connection between the PWM output pin on the Mini and the IN terminal on the Laser power supply.

The dupont headers can be a bit loose sometimes.
