Probe Screen Combined with Tool Touch Off

Hi All,

I have been playing around with Linuxcnc for a while now. I have found that I want to have a tool probe as in the famous Probe Screen . But I also want to have a Tool Touch Off for x y and z. I have found some basic code online that I modified to suit my machine.

However, since installing the Probe screen, my touch off does not work. My experience level is only sufficient to let me modify existing and understand the general principles. My problem is that I cannot work out why the probe screen and the touch off will not work. Does anyone have any ideas?

I have attached my full machine setup.

Many Thanks,
