What is the best replacement board for a K40 laser upgrade

What is the best replacement board for a K40 laser upgrade?
I am looking for one that supports the rotary option.
It looks like Cohesion 3D is no longer available.

I ran my 45W machine with a MKS DLC32 controller. I didn’t try to run a rotary, but I don’t see any reason it won’t work with a rotary.

There is also boards made by Monport that claim to be plug compatible, so they should just plug and play…

:smiley_cat:

I did put a monport board on my k40. Difficult to get it connected. after a year I finally got it. Monport support is non existant.
