It should work driving IN with pwm.
With pwm wired to the laser enable, you wouldn’t know what IN has voltage wise. With the need to pull IN low, indicates a faulty lps. It should not lase with no connection to the IN terminal.
Once you get it working properly you can solve most of these, but depending on the category, you might not be able to mark it solved. I don’t think the community laser talk has the ability to be marked solved… I have no idea how this is figured.
It will have a check box if you can solve it 
at the bottom or within the hamburger menu icon
, also at the bottom.
