The HOME/G28 buttons functionality is hard coded into the binary of the control, In other words, there is no way to alter the functionality of this button. The only way to assure this button does not get pressed is to place a cover over the button.

I have a Haas VF 2ss and need to modify the Home/G28 macro. I have a very complex set up and if an operator were to send all axes home, it would crash. I usually do Fanuc, but this is the first time I am working with a Haas. The machine has a setup that will not be changed, as it was bought to run a specific family of parts for many years. Can anyone tell me if there is a linked macro for this button? I am hoping that it is not being handled in the ladder

What happens if the power goes out???
Sounds like a disaster waiting to happen.
You can home each axis seperately. Disaster averted!Originally Posted by WallyL7

There are 2 phases of the zeroing process, I and II. By default, all axes zero during phase I. By setting any of the bits below to 1, that axis will be zeroed in phase II.
266:6 - X
267:6 - Y
268:6 - Z
269:6 - A
270:6 - B

He's worried about the operator "accidently" pressing the power up button or sending all the axis' home...I doubt this operator will only "accidently" zero one axis at a time...
No, he is referring to the HOME/G28 button/function and not the PWR UP.
Sounds to me like he is worried about the machine simply going home - since that is where it will crash. And yes. It sounds like a disaster waiting to happen given his confidence level in the operator.
If you are going to cover one of the buttons, you can cover both.
The parameters I listed previously, will alter the behavior of every G28 type command/button.

Bing! Bing! Bing! And there lies the real problem.
Ken, can you explain to me a little about the differences in phase I & II.
I can go to the home position, just not all at once.
Normal VF-2SS G28/Power-up procedure:
Z
XY
Tool-Changer
If you want: XY, then Z: Set parameter 268:6 to 1 The new procedure:
XY
Tool-Changer
Z
As a reference, if you set all of the values for the parameters mentioned to 1, it will behave normally.
Thanks,
Ken Foulks
