K40 controller card

I been reading forums all day so now im really confused lol. I know that i would need to do a card upgrade to run lightburn but what are the best control card to update that is plug and play? So i guess this question is geared towards those on here that own a K40 any info would be great.

I purchased a Mini Gerbil controller card to upgrade my K40 Laser. It’s plug and play and works very well with Lightburn software.


The other option is the Cohesion3D LaserBoard that I make. The LaserBoard has built in Trinamic stepper drivers for super smooth and quiet motor performance, native support for a Z Table and Rotary attachment, the ability to hook up a screen, and comes with a power supply included to power it since the K40 cannot provide enough power to run everything I just said.
