Y Axis not working in Plasmac screen

If it is a gantry machine then it needs to be homed before you can manually jog the Y axis.

Interestingly if I unlink haul.program.is-paused in a sim I see similar behaviour:
[b]Actions on the simulator:[/b]
Homed the machine and enabled the torch
Started a job
While the thing was moving to start the cut, I set the ohmic volts right up
When it tried to do the ohmic sensing it failed with the message "pierce height would exceed Z axis maximum limit". This stopped the machine
Pressed the pulse button. The button shows the countdown timer, but the torch does not fire
I cannot get it to fire by activating the float switch though.

I will  get the clients current config.  we may not be using the runstep.hal file any more as we are using the external button pins.
Not sure about the sim

Is there a complete sim config somewhere that can be used to test for this issue?
If so I can probably make a bit time to have a look.

The config posted above is not a sim but a quick glance does show a couple of oddities in runstep.hal:
# External Program Pause/Resume and Run/Step Buttons
# Pause/Resume Section
unlinkp halui.program.is-paused
unlinkp halui.program.is-running
net plasmac:program-is-paused => pr-or2.in0
net ispaused halui.program.is-paused => pr-or2.in1
net plasmac:program-is-running => pr-or3.in0
The two plasma:program-is-... signals seem to have nothing driving them, just two inputs connected together.

Have you thought of using the provided external button pins?
