Some board configuration/setting questions

So the cutter is finally running, some questions raised:
0. is there a manual/walkthrough to all the functions and settings for the Mk6 interface?

How do I set the center of origin for the cutter?
I have tried that and the on startup the red dot is on zero x/y (which is less than the x/y end switches, which is fine). But when I place something in lightburn just at the edge of zero y, the cut starts at -20mm (which left some engravings in the alu frame and messed my cut.
Correct power setting on the cutter (min/max 1 and 2)
I remember fiddling around with the power setting in the cutter ending up having all values set to 99%

The way most use it is with User origin.
Press the Origin button on the keypad and the current position of the laser head will now be the start point.

If you share your set up it will be easier to see whats going on.

Lightburn as some good info on this.

# Coordinates and Job Origin

There are a couple different ways to tell LightBurn how to cut the project within the work area of your machine.  You choose them in the "Start From" box on the Laser tab:

## Absolute Coordinates

**Absolute Coordinates** is the simplest - The page grid you see in the main editing window represents your machine's work area.  Anything you place in that area will be cut in the corresponding place on your machine.  Users with small lasers like the K40 will likely find this the simplest and most intuitive option.

In the image below, the two circles placed in the middle of the work area will be cut in the middle of the machine work area.  The green square in the lower-left of the image represents the Job Origin, and the red square in the same place shows the Machine Origin.  In "Absolute Coordinates" these are always in the same place.

For power, Min means the lowest power it can go when at slow speeds (changing direction or small circles due to acceleration) Max is then the power it will use when at normal speeds.
99% is the max the controller can visualize
