Very cool.  Im not that concerned about it right now.  I have no issues doing the z.. but how do you make sure the x and y are not affected? 

in what way?

Well so just say you have a piece that requires 3 different bits..

You do the first one, you pull that one out.. you put a different one in, you redo the z manually?  how do you ensure the x/y of where it is.. remains in proper position?  sorry if this is dumb questions, I am new to this..

As I set the initial work XYZ 0 in the centre of the workpiece the spindle can always be sent back to this initial position.

I just remove the first tool fit the new tool and re zero the z axis at the initial position.

There is never a dumb question so never apologise for that

I see, I am curious about one button on the dashboard.. 

 

What does this do?  Sets all three to 0,0,0?

 

How do we use this?  I usually just set the z.. then thats it.. should I be setting x and y too?  how will that affect my cam/gcode?

Yes exactly that, it’s your workpiece datum’s ? 

Once set you can return back to the same position over and over

So just say I use that,  I position a piece of wood on my bed.  I put the bit to the bottom left corner, and set the x,y,z to the bottom left corner.  How does that affect my gcode I am running?

 

I am thinking in my cam software, right now I am using Easel, which is not great.  I want to setup fusion but I am not knowledable on it.

So the software ( Vectric Aspire ) I use asks firstly asks for the dimensions of workpiece. Let’s say a nice bit of oak 300x300 and 30mm thick.

Then again within the software it then asks where will the workpiece datum 0,0,0 be I select top face and the middle in X and Y axis on the material.

So 150mm in from bottom and side edge.

Then I create my design could be text or a relief whatever you like.

Then let it create my cutter path G codes based on cutters selected.

Export the G code cutter path to my desktop.

Now on the router I home the machine first and then move the spindle to somewhere central in the workable area.

i use a rule diagonally across the corners to lightly mark a cross in the centre of the timber.

Fasten down the material making sure its edges are square to frame if the machine.

I use a v carve bit in most of my projects so install and tighten then jog the cutter / spindle over this cross and whilst lowering the cutter making sure to zone in on the cross on the timber.

In the Z axis use a feeler gauge between the top of the timber and the tip of the cutter till I just can’t move the feeler freely. (0.15mm)

Once there set this as your “ SET WORK XYZ “ on your control screen. This datum now tallies up with what I selected originally in the software.

Upload your g code and press start and away you go that’s it.

Hope this helps I’m sure that there are many ways in which to do this and to be honest it’s the way I have always done it without any issues.
