Gcode and soft limits question

Thinking about upgrading my crossfire with Langmuirs THC rather then building everything my self… I have most of the parts, but never seem to get around to designing some of the parts I need for the conversion.

Using Langmuirs conversion would require moving to FireControl. And I would like to see a complete list of support Gcode and Mcodes for Firecontrol, along with any other supported commands. Any support for Macros? I know people have asked in my Mach3 test macro thread if my program works in FireControl.

Also I have not been able to find anything about soft limits with FireControl… I really enjoy using soft limits on Mach3, it prevents me from running parts that do not fit depending on where I set my start location.
