I then tried bypassing my modified Ramps fan extender, and still the exact same result. (Still running the G28,G29 command direct from the SD card without connecting USB cable / Pronterface)

Going to try one other thing, but at this point I'm about stumped...

Did a few more tests:

Replaced the vector_3.cpp file with the original file before the Roxy update. No Luck. Same result as before. Reverted back to the Roxy change.

Enabled both EEPROM_SETTINGS and EEPROM_CHITCHAT. (They have been disabled up until this point) No Luck. Still same results.

Changed the "#define NUM_SERVOS" to "1" in the Configuration.h file (mine was set to "3") Still no luck.

Finally I reverted to the version of the Marlin_main.cpp file I used before the Roxy updates. I am currently probing for the 10th time without any issues. (running G28,G29 from Pronterface)

It must be something with my "Marlin_main.cpp" that has been updated with the Roxy code... I've attached a link to that file, if anyone feels inclined to give it a stab. (Thanks in advance!)

One more thing, when I go back to the Roxy version of Marlin_main.cpp and upload it to my Arduino the LCD screen gets all wacky. I have to power down and then up again to get it back to normal. Here's a link to what it looks like:

Hopefully this helps.
Thanks again for any help!
