As a close out to the topic...(unless I find other issues).
PM728VT, X Y and Z axis.
X is now positive i.e 0 to 480, homing on left corner of table, and cutter moving to the right, table moving to left. Total distance 480mm.
Y is negative. 0 to negative. Homing on front of table. This sets home in the negative. With table cutting moving towards back (i.e. table moving to front)
Z is Negative 0 to negative number. Homing at top of Mill. Distance 317mm.
Working as expected. So basically unless homing at back for Y and bottom for Z, these numbers will reference negative unless there is another way to "set" zero as home at the other end of the soft limits.
Thanks for everyones input.

I think using words adds complexity from interpretation of explanation, Machine Coordinates for X0, Y0, Z0
Z0 = Head Fully Up
X0 = Table fully Right
Y0 = Table fully Forward
Axis travel direction for table and head:
Z+ = /\ Head moves up
X+ = < Table moves tot he left
Y+ = \/ Table moves towards the front
Z0 = Head Fully Up
X0 = Table fully Right
Y0 = Table fully Forward
Axis travel direction for table and head:
Z+ = /\ Head moves up
X+ = < Table moves tot he left
Y+ = \/ Table moves towards the front

Excellent! do you have a build log somewhere on social media?

Unfortunately not yet, but am looking to get this cataloged for others as I have completed quite a few 3d printed parts to help support the PM728VT machine to CNC.
As such this can help others move across more quickly.
I want to make sure there is a positive ending before releasing the build program, just to make sure others get to a realistic endpoint.
Currently using a laptop, and seems to be Ok. But may need to get a miniPC to run it all so just incrementally addressing each issue.

nice! please post up when its done, that is an interesting machine, look robust for a bench mill/
