Hi Everyone,

I am setting my my 4' by 8' router table controlled by a F8025M. I've just finished setting up all the parameters associated with the "Machine Reference Search."

When I finish a machine home, the "Machine Reference Zero" point turns out to be at X=-6.365, Y=-0.134, and Z=5.75 with respect to the actual origin (corner of) of my 4'x8' table. Here's a rough diagram where "M" is the machine reference Zero point and "o" is the origin (corner of the table):

........|......................................| ^
........|......................................| |
........|......................................| Y
........|......................................| |
M......|o_______________________| v
.........<----------- X ------------>


What is the best way to set up my table parameters and post processor with offsets, etc. to account for the difference between these two points?

My first thought is to set parameters P119=-6.365, P219= -0.134, and P319=5.75 then do a G00 X0 Y0 Z0 to move the spindle to the corner of the table. Then I can use a G59 X0 Y0 Z0 for my offsets.

Would this be the correct way to do this?
Is there a bettery way?

If I do this, will G90 moves still be referenced to the M point as the 0,0,0 point or will the G90 moves be referenced to the corner of the table?

Thanks for any help or suggestions.
