General Mach Discussion / G28.1 and Ref All Home Issue
« on: July 19, 2013, 06:52:47 PM »
The Good: I have just set up a Kitamura MC0 with Fanuc DC Servos with an Ajax/Centroid controller. General tuning is complete. Limit switches on + travel are intended to be used as homing switches when called for. Jog direction and limit switches are correlated (+Jog will activate + limit switch).
The Bad: If I hit the Ref All Home Button nothing happens. If I put G28.1 X(value short of limit switch) the axis moves to this intermediate point (in working coordinate system/not machine coordinate system) and then stops. If I put G28.1 X (Value past limit switch) the machine gives an "Axis X Position Error" Message. I have tried a G90 and G91 before the G28.1 (per forum suggestions) with no improvement. I have X++, X--, X Home enabled in Config/Ports Pins/Inputs. I have tried both with and without "Homed true with no home switches". If I select G28.1 No Initial Move the intermediate point move does not happen (so I unchecked that box). I have my soft min and Max set way beyond table travel so they are not involved. I have tried with Auto Zero on and off with no effect.
Other facts that may or may not be important: I can not Jog off a tripped limit switch. I either use hardware over ride and jog off or turn off machine and turn ball screw by hand to move off switch. I am using a demo copy to verify compatibility before purchase. Simple path G Code works fine.
I have attached .xml file. Thanks for any insight that can be given.
