I have y and a axis slaved on my G540. The slaving works fine when jogging and driving the mill but when I try to home the axis only the Y motor spins then the A motor spins when the Y has found home. They are trying to home independently of each other. "Big problem when you are driving a big gantry with two motors, it tends to want to rip your gantry in half" I can get the Y-A slaving axis to home but then the A axis tries to home. How do I make sure my A axis does not try to home while at the same time making sure slaved Y-A axis homes. I'm using Mach3. I've tried using the Mach3Mill.XML file from the Gecko site but I get the same thing. I have limits on the X Y and Z which I am also using as home switches.
I was using a cheap ebay driver board with no homing problems using the slaved Y-A. The Grecko G540 is a tremendous improvement over the ebay board except for this one nagging issue. I'm sure it's something I don't have correct in the Mach3 setup.
Any ideas?
