Mcfly surfacing wasteboard

[Kmcbrien1220 (Keith McBrien)]

i tried flattening my waste board on my Shapeoko 5 pro -4x2 using the facing tool path
i have set the Y axis as far as it will go , and when i start the file it starts about 1/8" from the edge(see pictures)
i cant get the Y AXIS to go any further to zero out ,i tried recentering it
if anyone knows why this is happening ,please help

Try the file/technique/documentation at:

Shapeoko 5 Pro - 4x2 Flattening File

This is the file that I used from cut rocket and it will not surface the entire wasteboard
It surfaces it and the x axis fine. but not the y axis, there is still a good 1/8” off from front that it does not surface

Hopefully @KevBarn14 or someone else with a stock machine will be able to chime in here.

Maybe enable the MDI and enter the command

G0 Y-0.125

(if that moves it 1/8th of a mm, then try Y-3.175)
