engraver control

ok has anybody had success with the mp1000-dthc.scriber post. i am having a hard time setting the limits in the post. i have set the offsets but the engraver is still not set with the offset that its at in relation to the plasma torch. i have included the post to see were im going wrong. i would also like to install a pause at m08 for a second or two. any help would be great. thanks

function OnAbout(event)
   ctrl = event:GetTextCtrl()
   ctrl:AppendText("plasma MP1000-THC post processor with engraver\n")
   ctrl:AppendText("Tools 100 and up are the engraver\n")
   ctrl:AppendText("\n")
   ctrl:AppendText("Modal G-codes and coordinates\n")
   ctrl:AppendText("Comments enclosed with ( and )\n")
   ctrl:AppendText("M03/M05 turn the torch on/off\n")
   ctrl:AppendText("M08/M09 turn the engraver on/off\n")
   ctrl:AppendText("Incremental IJ - set in mach2\n")
   ctrl:AppendText("The torch is referenced at cut start and every 500mm of movement thereafter\n")
   ctrl:AppendText("Designed for use with Mach3 and CandCNC MP1000-THC and Floating head Touch-n-Go\n")
   ctrl:AppendText("Post variables:\n")
   ctrl:AppendText("refdistance - set the distance between each reference\n")
   ctrl:AppendText("switchoffset - set your net switch offset amount \n")
   ctrl:AppendText("\nScriber uses tool numbers 100 and up")
