Ender Pro 3 Laser Conversion Question

I’m a total noob. Okay well I know some basics and I have great support through my Brother who has worked some magic with my Ender Pros. (I have two). I’m thinking about converting one of them to a laser engraver.

Reaching out to the community to help me breakdown what I need to do to the machine to get it to “GO”.

It’s running Marlin bugfix 2.0.x (2023/04/16) Mesh Leveling
Board Details: Creality V4
Protocol: 1.0
PSU: Generic

I’m assuming the thermistor info is not relevant and I do know that I’ll need the engraver module to replace the printer head. I see them on Amazon for about $70 so I’m thinking this may be an economical conversion.

I want to run the printer from my iMac. Other than maybe updating printer firmware is there anything else I need to be aware of to make this operational?
