Zprobe on Rambo with laser

Is it still possible to use a zprobe if you’ve remapped the z min to be a fan header to control a laser? Am I correct in assuming that the z min pins were used for homing Z? Would I need to remapped the z max to be minimum?

You can assign the zmin function to many different pins. So if you’ve used the pin named zmin for the laser, you can either move the laser to zmax or move the zmin (function) to the zmax (pin). Either one requires configuring pins_Rambo.h and reflashing.
