disable home button while running

I'm pretty sure EMC will not try and home when a program is running. You should try and see when running a safe program.

If not then you want to "and" the button and halui is in manual pins to your halui home pin. To do this you use the and2 component.

www.linuxcnc.org/docview/html/man/man9/and2.9.html

The and2 component takes two inputs and has one output. If both inputs are on the output is on. So one input is your button and one is the halui is in manual pin (don't know the exact name).

The xml file only creates the pyvcp things. The and2 is a HAL component so it will be in your .hal file.

Look in your .hal file to see if you all ready have a loadrt and2 line. If not you can in your postgui.hal and add the and2 and don't forget to add it to your servo-thread with addf. The reason you do it there is you are connecting to the pyvcp button so you have to wait for it to load.

So get the and2 part added first and make sure that works...

You should have two threads the base-thread and the servo-thread. I have no idea why they are named that. The base-thread is the fast one used to generate steps and the servo-thread is a one that runs about 1/4 as fast as the base-thread. The servo-thread is the one you normally use for things like this.

It doesn't matter what kind of machine you have hal commands go in one of the hal files and pyvcp stuff goes in the xml file.

You can load and add the and2 in either hal file. Only the connections to any pyvcp component MUST be done in the postgui hal file.

What is your addf line?
