In the program below, I have removed all Z moves, both rapid and feed rate. If you look at line 90 there is a G00. This is where a Z rapid would normally be but since I removed that line in the post, the Z move does not appear. Is there a way to make the entire line go away?

OK…Made it go away by setting rapid clearance to 0, but I’d rather make a change to the post so rapid clearance can be left alone. Setting it back for a plasma part after changing it to 0 for a flame cut part is just one more thing to forget. 
That line is harmless but if you want to get rid of it, put this line right at the beginning of your OnRapid()
if(math.hypot(currentX - endX, currentY - endY) < 0.001) then return end
