Do you have the ‘pot’ controlling the voltage on the IN pin of the lps?
The L input of the lps is wired to your pwm output.
If this is correct ensure that the $30 is set to 1000 and S-value Max is also 1000.
$32=1 and $31=0…
If these are off, it can change the range of the pwm…
Try this setup for Lightburn
Good luck
