I will also include any specific files I created / edited with the caveat that they have been created for my specific needs. I will also try to link the sites I found useful and link to the places I got firmware from.

This instructable will assume you can connect up the board to the machine.

Spoiler, it works really well for my needs, noting I only use the K40 occasionally and for relatively small gifts mainly for friends and family. Inevitably I needed the SKR board to run a Mainly Printed CNC router that I was building, and I had the CNC Shield, some spare DRV8825 stepper drivers and a spare Arduino and thought I would give it a bash instead of splashing out for another BTT SKR board. This worked really well and is the subject of a different instructable. I then installed a BigTreeTech SKR V1.3 with DRV8825 stepper drivers. I also downloaded Lightburn to give it a go as I had heard good things and spent a couple of weeks creating stuff in lightburn, saving as on SVG, loading into K40 Whisperer and engraving, quite successfully. So I bought the K40 Laser having read all the horror stories about the controller and the wiring and the lack of power control and setting the house on fire and so on.
