this is my first cnc build and exposer to hal and ini files so bare with me please.
after setting up the Plasmac configuration i received and error when i tried to start the program.

The error
Starting LinuxCNC IO program: io

net plasmac:torch-on => parport.0.pin-01-out

# a 1 here allows multiple tools to be used

setp plasmac.multi-tool 0
net plasmac:air-scribe-arm plasmac.air-scribe-arm => parport.0.pin-16-out
net plasmac:air-scribe-start plasmac.air-scribe-start => parport.0.pin-17-out

i understand why the pin needs to be a float i just have not been able to figure out how to change it from a bit to a float, any help would be appreciated. thank you

The parallel port pin is a bit type pin.
Normally plasmac.arc-voltage-in would be connected to something like the output of an encoder.
What hardware do you have and how is it physically connected?

I am using a C10 parallel port breakout board at the moment( www.cnc4pc.com/c10-bi-directional-parall...-interface-card.html ).
i was hoping to get started with this then move on to add more and upgrade later

I don't have an external THC at the moment, i was going to add one later or attempt to build one with either a raspberry pi or an arduino.
do you need a THC to use plasmac?

Yes. That is the main reason why it was built.
But you can run the sim without any hardware, to get used to it.

It should be possible to use a Mesa THCAD and run that into a software encoder .
That should work with a parallel port and you could upgrade from a parallel port at a later date and keep the THCAD.
You would be restricted with I/O and probably need shared home switches and no limit switches.

But if you go to the trouble of ordering a THCAD, you might as well add a 7i96 to the order and be done with it. Its really the cheapest THC available.

The plasma cutter i ordered has a 1/50 torch head voltage divider built into it. couldn't i use run that into and arduino analog input then write a bit of code to output one pin or another based on voltage readings, then i could use Plasmac mode 2 for the z control

Probably but don't go over 250 volts or you'll fry the input.
That is probably fairly safe upper limit for a plasma cutter in the 40-50 amp range though.
It will still be a crude substitute for a THCAD.
