@featheryjam2 said in Homing Issues with CoreXY and two z-axis drivers [SOLVED]:
I may have figured it out. Apparently it does not like when you do G28 X or G28 Y in the homez.g script.
That's correct. You can use M98 Phomex.g and M98 Phomey.g instead if you need to. However, as you are homing Z using a G30 command, you should have the Z endstop position set to "none" in the M574 command, and in that case the firmware will not let you home Z unless X and Y have already been homed.
