ProbeBasic and sidemount, retractable 3D Probe

Hi, I'm new over here.  
I made a CNC router with a retractable 3D probe mounted next to the ATC Spindle.



I also installed ProbeBasic last year, as it seems to be a fantastic GUI with everything I could want from my CNC router. 
So far I have ProbeBasic up and running and I can run the probe subroutines. 



But my retractable, offsetted 3D probe configuration is maybe a bit special and needs a bit of customization to work. 
I'm hoping its possible in ProbeBasic.

Before I start hacking away , can someone point me in the right direction for the following:
- Configuring the offset position of the 3D probe relative to the spindle
- Programming a command that triggers an output, when initiating a probing subroutine (which I can use to control a pneumatic 3/2 valve). Would I need to add this to every subroutine, or is there an easier way?   
- And maybe an interlock to make sure no tool is loaded when probing

Any help is much appreciated. ) 

very easy, enter an x and y offset in the tool table for the probe. these are normally 0.0000 since the tool and spindle share the same centerline, but if your probe is offset, you can find the center of a probe calibration ring with an indicator on the spindle, and set a work offset to zero for x and y. then use the probe (with the probe tool offset for x and y set to zero and use the probe position only option on the probing page. when the center has been probed, the x and y dro's will show you how far from the spindle centerline the offset probe center is. enter these in the tool table under the x and y offset column, save and reload the table. if the entries are correct, the main dro's should now show zero.

now when you load the probe tool, the tool offset is called up which will include the x and y offset. so when you probe the work to set an offset it will be taken into account and when the probe tool is unloaded in the user interface and its offset deactivated the zero point will correspond to the spindle centerline.

if you do not have the x and y columns showing in the tool table, open the custom_config.yml file from your config folder and at XY to the tool table display settings as shown below:

This will now display those columns in the tool table when you next run probe basic!

Enjoy!

The tool table should look like this once you add X and Y to the custom_config.yml file:
