No Home All button in Axis

From reading other posts I believe this is an error in my homing configuration so this button in not displayed. I suspect this issue relates to my 4th axis. This machine is a Bridgeport knee mill with a rotary 4th axis (A) which spends most of it's life on the floor next to the machine unplugged. I have my XYZ where I can home them individually. Z is Home search sequence 0, X is 1, Y is 2, A is 3. When I home all I want X,Y,& Z to seek to home and A to just Home where it is. Am I on track or totally off base?

Thanks!

I'm afraid the RTFM was not helpful, I've read that document and I have no idea what it says! All of this documentation is reference documentation and is only useful to somebody who already knows the system. That HAL code makes no sense to me and I can't even find that section in my HAL file.

A valid HOME_SEQUENCE number should usually be included since omitting a HOME_SEQUENCE eliminates the joint from HOME ALL behavior as noted above.

You have not configured your home sequence in your INI.

In your X-axis section:
HOME_SEQUENCE = 1

In your Y-axis section:
HOME_SEQUENCE = 2

In your Z-axis section:
HOME_SEQUENCE = 0

In your A-axis section:
HOME_SEARCH_VEL = 0
HOME_LATCH_VEL = 0
HOME_USE_INDEX = NO
HOME_SEQUENCE = 0 (or other valid sequence number)

Humm, I specified those values in pncconf. Do I also need to manually add them to the .ini file manually??

Everything Aciera wrote is missing from your ini file, they have to be added manually or by editing the config in pncconf, but it is easier to edit it.
