I'm running a mini mill with physical limit and homing switches.  No tool changer or anything fancy. 

I fire up the machine, Ref All axes and zero all axes, and then move the machine to some arbitrary position and click "Remember Position".  If I then jog the machine to some other position and click "Return To Position", the Z axis moves up until it hits the home switch, but the X and Y axes don't move at all.  No errors or warnings show on the screen.

Not sure why it doesn't return to the position where I originally clicked on "Remember Position".  Have I misunderstood how these buttons should work?  Or missed a step somewhere?  Or is there is a bug in my setup?

PoKeys / Pokeys57CNC and homing to middle ?
« on: August 16, 2019, 08:06:53 PM »
I'm converting a mill to use a Pokeys57CNC controller with Mach4, and looking at setting up the homing switches.  Currently the homing switches on the X and Y axes use inductive probes for homing switches, and they're located in the middle of the travel.

The Pokeys user manual describes how homing switches can be configured for various options ("On home" and "Out home"events etc) but I can't see one which allows for homing to a switch in the middle of travel, ie when the machine powers up, it may be either to the left or the right of the home switch, and will need to travel in the appropriate direction until the home switch changes state.

Is this possible with the Pokeys575cnc or will I need to change to home switches at the ends of the travel instead ?
