Thanks everyone, for your insights and answers.
I’m actually working on a mount to put the driver just above the laser, using HicWic’s universal mounting system, but I might end up not using it, depending on some of the other wiring. Speaking of which:
I think I saw that there is a place to connect the laser cooling fan on the driver board – is that correct?
I also have two line lasers, to create a target for positioning the big laser – is there a place on the driver I could get power for them, as well?
