Nothing too fancy about the Chinese scale I examined. IIRC they have guard marks both sides of the index marks a few mm each side of the 50 mm. Simplistic way to home would be to jog to a given point and kick loose homing and pickup the first real mark on each axis. I did. Something like this on one of my machines. Used a tab on one end of the table with a hole in it. Jog to align laser pointer with hole, that gave me a XY starting point, Jog to Z max, switch or another laser pointer and kick loose homing. Clearly it is time to go read the newest version of homing see what is easy. I’m a great believer in the KISS principle.
