Newbie next steps before running a program

Hi,

So homing works for me on my 6040 3-axis (three combined home and limit switches, XY in the same corner and Y at the top of travel).  I back off the switches by 2mm.  My Z has to have inverted direction.

So when I home my LCNC DRO reads ABS X 2.000, Y 2.000, Z -2.000.

I'm starting to become slightly familiar with the notion of work vs machine coordinates.

I'm a bit unsure about what I do now prior to running a program.  In another thread I hit gold:

rodw: "The biggest revelation I had as a newb was to use the G54 offsets to set the zero position and forget about G53.  The best way to do this for Z is to use a milling cutter or drill bit of known diameter (lets assume its 10mm) jog down until you can just roll the drill bit under your tool. Then use the touch off feature to touch off at 10mm. This is equivalent to running G54 Z10 in the MDI window. Watch The DRO's to confirm the zero position has changed. Now Z0 will be the top of your job.  Likewise use a wobbler to touch off your X0 & Y0 coordinates. Say your wobbler is 6mm in diameter (3mm radius) and you are touching off at top left,
touch off x = 3mm, y=3mm. Alternatively, a sharp pointer in the spindle should let you position to X0,Y0 so touch off accordingly."

So I'm using gmoccapy, what buttons do I press and what do I enter where to be ready to run the program?

Please explain it like I'm 5, I have zero experience on CNC and machining.

From my research the LCNC docs cover each part of the system really well but I'm not finding any workflow?

A video that shows the process from homing to running a program on gmoccapy (bonus points for the Vectric config would be epic?  If such a thing doesn't exist then if I can figure all this out I might record and post one.

Thanks.

This video is quite good showing how to use an edge finder (wobbler) correctly.  

I am very much a noob with miling too. But it is more or less identical to how I worked with a DRO on a manual mill. I used 200-300 rpm.
I can highly recommend buying a Starret edge finder. Way better than Chinese ones! 
An alternative is to put a very csharp stylus in the spindle and set it close to the stock and jog to the 0,0 position
Gmocappy has a button aong the bottom that opens the work offsets. The video shows a 2 step process, but in practice, you do it in one step.
But if you are cutting a part from a sheet of wood, you probably just need to jog to where you want to start and touch off X & Y .

Without a tool changer, I was told to generate seperate G code for every tool you use. 
Then all you need to do  is touch off X & Y, load a gcode file and touch of on Z with the appropriate tool.
I suggested  to use a milling cutter of known diameter and they use a tool setter to do the same thing...

Good luck!
