printing on the back half of bed

[shackleford92]

i am honestly not sure whether i have fudged the printer or an orcaslicer setting.
printer: neptune 4 pro
steps for ME to reproduce: set an object centered on the build plate in orcaslicer, upload, and print
expected outcome: object to print centered on the bed as displayed in slicer software
issue incurred: object is sort of centered on the x axis but prints on the back 3/4 of the y axis
what i believe may be relevant information: printer homes to x:141.75 y:97.05 z:10(the asymmetrical x,y raises flags in my mind), i have been dealing with this for a while but i do small prints and have not run into too many issues, the homing seems to be a printer thing and not slicer?, i have not directly edited printer.cfg MUCH the last thing i did was add and comment out resonance includes
#[include adxlX.cfg] ; Comment this out when you disconnect the Pico/MellowFly accelerometer mounted to print head
#[include adxlY.cfg] ; Comment this out when you disconnect the Pico/MellowFly accelerometer mounted to print bed
i do not remember it being an issue at that time in the may time frame 20240521,

EDIT:
the gcode preview shows objects being centered
it bed meshes the proper area
it then proceeds to print on unheated area of the bed

it seems something has gone screwy in printer.cfg or if an end stop has shifted
any help in resolving this would be greatly appreciated

i have attached a 3 minute cylinder print and a photo of my outcome, can someone verify this is a ME problem with their WORKING printer. apparently github does not support *.gcode so i have zipped it
Cylinder_T=2m55s_W=1g_C=$0.01.zip

this is what comes out of my printer

not as far back as usual, but the machine has attempted to print OFF the back of the bed on most larger prints, this behavior is semi erratic

sooo, not sure if this was from bit corruption from an outage BUT those asymmetrical homing coordinates were baked into my printer.cfg

[safe_z_home]
home_xy_position: 141.75,97.05
speed: 100
z_hop: 10
z_hop_speed: 5

making these alterations seems to have resolved my issue

[safe_z_home]
home_xy_position: 117.5,117.5
speed: 100
z_hop: 10
z_hop_speed: 5

unsure if this came from fat fingering, source, corruption, a bad git pull, who knows

may be worthwhile to commit @halfmanbear

"When using a probe to home the z-axis, it is recommended to define a safe_z_home section in printer.cfg to home toward the center of the print area."

Due to the inductive probe being offset from the print nozzle, the homing coordinates are the centre of the bed with the sensor offset applied to X and Y. This ensures the probe is homing in the very middle of the bed.
