Probe Basic Probing Inverted

While using probe basic I have found for outside corners probe selection.  I have to select all opposite corners except the center in the 3x3 (tic tac toe looking ) matrix.  Everything appears to be working correctly just have to invert.  I have checked all of my accesses and all seems to be fine except the probing function of probe basic. Anyone else experience this or have any thoughts?

Thank in advance,

i responded to your git issue. the probe routines are correct, your issue is your machine setup. many new folks get things a bit twisted as they view motion from the perspective of the table when whats actually happening is motion relative to the spindle.

gantry machines (head moves around) DOES actually follow expect cartesian motion because the spindle is what is moving in all 3 axes. however when you have a machine where the table moves, everything is opposite to the motion of the table because the spindle is still in the x and y axis. so we are moving the work and not the spindle.

in a traditional mill where the table is what moves:

table moving rearward = Y minus
table moving forward = Y plus
table move right = X minus
table moving left = X plus

because the spindle motion relative to the work is what is moving.

Z axis is also tricky. on a knee mill it is also opposite, where the knee moves up it is Z minus

on a VMC, Head Moving up is Z plus, Head moving down is Z minu. this is because the tool is actually moving with expected cartesian coordinate system.

Hope this helps!
