Marlin 2.0 Bug? Bed centering issues on Lulzbot-Prusa Mini Hybrid (no replies)

I’m currently in the process of upgrading my Lulzbot Mini into having a Prusa Mini bed. Making good progress on it. Decided that with removing the bed leveling washers i needed to flash custom marlin firmware. I grabbed Marlin 2.0 and got nearly everything configured and even got a test print (although it needs some tuning). The problems arose when i tried to follow this guide to center the print on the new print bed. [www.youtube.com]

When i went to uncomment the //#define MANUAL_X_HOME_POS & the //#define MANUAL_Y_HOME_POS i ran into really weird problems. I was able to get the x-axis to center although instead of being a negative value it was positive. But when i went to put in the values for Y i got some weird grinding sounds as if the stepper motor was running the wrong way. I tried switching the y value to the opposite since the y axis is flipped, but either way it does not work. Additionally when inputting a G00 X90 command sometimes the Y-Axis will move too! This should not be happening! And only seems to cause issues when the #define MANUAL_Y_HOME_POS is uncommented. I’m wondering if i encountered a weird bug in Marlin 2.0. Some have suggested that Marlin 1.1.9.1 is more stable.

Anyway, any suggestions? Comments on my project? This is the first time i have dug into marlin on my own.
