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.

Well rather than “RTFM”, which is a bit rude, is no help, talk about which bits you don’t understand.
Not only will this help you but help the devs make them understandable to a wider audience.
Help is a two way street.

Perhaps there is an error in the pncconf wizard? Or more likely I've done something wrong. I'll certianly go back and try editing my ini file directly , but shoulden't the screen shots below have worked? Thanks

I added those lines to the HAL file and I did get it working, but I needed to put them under the joint section, not the axis section. What is the joint anyway? How is it different than an axis? there seem to be duplicate entries for the limits in both the axis section and the joint section. Should the limits be duplicated in both sections? It's working so I guess it does not matter.

Thanks

i believe you have an A axis with no homing switches. It's why pncconf didn't set the home sequence. I have modified pncconf to ignore the A axis home switch requirement.

joints are the motors that are required to make an axis move.
Some axis require more then one motor (joint)
