Change position of A axis home

[mishikwest]

Can't seem to find parameter to change the A axis home position. Need to change it to facilitate loading and unloading a fixture upon cycle completion.

parameter 224 rot axis zero offset doesn't seem to do anything.

There's no need to change the home position:

(END OF PROGRAM)
G0 G54 Aa.aaa
M30

Or what I do:

(END OF PROGRAM)
G0 G53 Z0.
G53 X-15. Y0. Aa.aaa
M30

Using G53 you can handle jog the A axis to where you want to park it at the end of a cycle, go to the position screen and simply use the value you see in the A axis readout.

I don't think you can change the home axis itself with parameter, if you look at rotor motor of the axis you will see the red eye, that is what detect home. make sure you know what you are doing, if intend to alter the home.

Kinda like matt is saying you can use a fixture offset for the A axis at the end of your part program.

Lets say you run G55 on your part program.
at the end
have a G00 G90 G56 A0.0

just jog your A axis to were it needs to be when loading and set your g56 fixture offset.
