@Jet0024 Welcome to the forum
The two tools will have to different requirements on how they run. Also depending on how the pen is mounted, weather replacing the plasma cutting tip or mounted to the side of the plasma torch would adjust the relationship between the tool center and origin .
You will need a a pause for a tool change.
the code for the sharpie will also need . NO THC. no pierce delay, no pierce height, no fire on, no fire off.
if you have Hyperthem 45xp you could use marking consumables the would make marking a little easier code wise. Marking with plasma torch?
or the Easyscriber https://www.theeasyscriber.com/ these two options do keep the relationship between the origin the a the tool center the same which is a huge benefit.
In the end if you want one program when using a sharpie we will need to produce then modify the code for the sharpie then combine the code with standard code to the cut the part.
Running two programs that have the same origins back to back would be my preference.
