Hi I Have Problem With Probe Basic Probing
So My CNC is:
X+ Left To Right( 0 - 330)
Y+ From Front To Back ( 0 - 200)
However When I Want To Probe Front Left Corner It Seems Like It Is Probing X Properly But Y Is Flipped
So In order to probe Front Left Corner In RL I'm forced to choose Back Left Corner in PB GUI

I think Probe basic is based on this:

It Seems Like My Y Axis Is Inverted In Wrong Direction
However I Did Set My Params in Ini
HOME = 200.0
MIN_LIMIT = 0.0
MAX_LIMIT = 200.5
HOME_OFFSET = 200.0
HOME_SEARCH_VEL = -5.0
HOME_LATCH_VEL = -5.0
After Homing It Moves In opposite direction
Is that Mean I need to Invert Motor Direction and Change Home_Search_vel to positive?

Axis direction is the direction the cutter moves through the work on a Cartesian coordinate system. For moving gantry machines it is literal but for table motion machines it can be confusing because it's inverse of what one might expect (if thinking the table is what is traveling in the + or - direction. When the table moves toward the front, the cutter is moving in the y+ direction through the work, when the table moves to the left it is the x+ direction because the cutter moves through the work in the positive direction. So setup your machine accordingly. Home should be 0's, if your switches are on the wrong side you can use the home offset setting to correct.

Thanks For Info I Fixed It. Followed Directions From LinuxCNC Docs On Referncing Axis Movement And Directions Noted by pommen
