Here is a portion of what i believe is my profile.
Like I said, the file is huge I can't post it all.

I noticed that my profile.xml is in the macros folder as well as the mach3 root folder. However, they are different ie do not contain the same information

Thanks for the replies.
The torch seems to be doing initial ihs at the start of the first cut. When it moves to the second pierce it does not do ihs, it lifts from the table about 2 inches and tries to spark.
I do not now how to set up the THC, assign a pin to the ohmic cap and I'm not sure what thc I'm using.
Basically, I bought the unit from a shop where it was being used on a daily basis. I kept everything set up the way it was when I bought it. I was able to cut various pieces but something changed and I don't know how or why.
My profile is huge, won't let me upload to the forum. Is there a section that I should copy and paste?

As far I know the THC button is off(LED is off)
I have been able to run the table with it off.
It is a machitech 300 and Hypertherm Powermax 1650

I'm not really sure how to use the THC function. It seems like when I have it on, it doesn't work. torch drives right in to the plate if there are uneven surfaces. Ohmic sensing cap does not seem to be working. Please pardon my ignorance, this is all brand new to me.

I am very new to CNC and trying to learn how to use mach software to run my plasma table. I have been able to cut parts after some trial and error, lots of reading and tutorials.
For some reason, my torch is moving off it's path and sparking about 2 inches off the table when it goes from cutting one part to the next. It cuts the first piece fine and then moves to it's next position in the cut sequence, then it raises about 2 inches and tries to spark. Sometimes it does not move to the next part in the cut sequence but goes way off course and tries to spark several inches off the table. I have all new tip, nozzle, cap etc. so that's not the problem.
I feel like it's something simple but I don't now what a lot of the controls in mach 3 actually do or mean. I have been reading and watching tutorials but just can't figure it out. I need to get it running. Any help would be greatly appreciated.
Thanks!
