      I have a cartesian setup and I want my 0,0,0 home to be in the center for X and Y. For instance, my X settings range from -243 to 243 but when I home it is still setting the X min as 0 rather than -243.

      I've tried adding "G92 x -243" to the end of homex.g and attempted entering it into the console. It does not seem to acknowledge negative values.

        Don't use G92.

        Use M208 to redefine your minima and maxima values such that 0 is in the center.

        Here's a detailed example: https://drmrehorst.blogspot.com/2018/07/ummd-better-way-to-set-up-origin-and.html
