Looking for firmware for RDC6445S(ec)

I have the above controller with firmware RDC-V35.01.03
everything seemed not bad until I tried a rotary by switching the y
after doing that and trying to return to normal I’m having homing issues . controller no longer homes y at start
if i try to home from lightburn it trys to drive through the limits
I also don’t think its firing the laser correctly
(at first I couldn’t move the y from control but now it moves after opening rd works )

it will home from rdworks but I really don’t know rd works

i’,mabout to uninstall/reinnstall lightburn
