How to change from Ohmic to float switch

Hi
I have a machine that is fitted with a float switch and an ohmic probe (proximity sensors). I need to remove the ohmic function and replace the probing with the float switch.
I looked at all the usual files but could not find a way to do that. I could not find where the ohmic probe debounce output is used for instance so I am a bit lost here.

If it is a PlasmaC config it will be in the connections.hal file.

I am looking at a backup of the config files. This is what I see. Dont know if it is complete or correct
Code:
#***** debounce for the float, ohmic and breakaway switches ***** # the lower the delay here the better # each 1 is a 0.001mm (0.00004") increase in probed height result loadrt  debounce          cfg=3 setp    debounce.0.delay  5 addf    debounce.0        servo-thread setp  hm2_7i76e.0.encoder.00.scale -1 setp  hm2_7i76e.0.encoder.00.filter 1 setp  hm2_7i76e.0.encoder.00.counter-mode 1 loadrt and2 count=1 addf and2.0 servo-thread #***** arc voltage lowpass cutoff frequency ***** #***** change to the cutoff frequency you require ***** setp plasmac.lowpass-frequency 0 #***** the joint associated with the Z axis ***** net plasmac:axis-position joint.2.pos-fb => plasmac.axis-z-position net plasmac:arc-voltage-in hm2_7i76e.0.encoder.00.velocity => plasmac.arc-voltage-in net plasmac:arc-ok-in hm2_7i76e.0.7i76.0.0.input-06 => plasmac.arc-ok-in net plasmac:float-switch hm2_7i76e.0.7i76.0.0.input-04-not => debounce.0.0.in # net plasmac:breakaway hm2_7i76e.0.7i76.0.0.input-03-not => debounce.0.1.in net plasmac:ohmic-probe hm2_7i76e.0.7i76.0.0.input-03-not  =>  and2.0.in0 #net plasmac:ohmic-probe hm2_7i76e.0.7i76.0.0.input-03-not =>  net plasmac:ohmic-probe_out  and2.0.out => debounce.0.2.in net plasmac:ohmic-enable plasmac.ohmic-enable  => and2.0.in1 net plasmac:torch-on => hm2_7i76e.0.7i76.0.0.output-01 # a 1 here allows multiple tools to be used # gcode M3 S1 needs to be changed to: # M3 $0 S1 for the plasma torch # M3 $1 S1 for the scribe # M3 $2 S1 for spotting setp plasmac.multi-tool 0 # net plasmac:scribe-arm plasmac.scribe-arm => ***YOUR_SCRIBE_ARMING_OUTPUT*** # net plasmac:scribe-on  plasmac.scribe-on  => ***YOUR_SCRIBE_ON_OUTPUT***

Yea, that is the one. According to that you have a float switch on input 4 and ohmic on input 3

That is correct. The ohmic is put through an AND gate to disable the probe during cutting.
As I understand the float switch will act as a safeguard for the ohmic probe as it is setup at the moment. So the question is how do I ignore the ohmic and only use the float for probing?

In the Run Tab uncheck Ohmic Probe Enable.

And then I have to calibrate the float travel again right?

Yes, if you haven't been using it then it is best to be safe.

or '#' out the ohmic line in the Hal file
