Hi all i have a mazak sqt200-msy with t plus control. I am trying to tap holes on sub spindle side with eia program.

The tool holder is a double z axis live tool, one side for main and one for sub. To use on sub side you have to program

the tool rotation oppisite (m204). The problem is i program

m204s500
(position for hole)
g84.2 z___f___m204
g80

the mill spindle stops before it starts the tap cycle then starts m203 and at bottom reverses to m204. This is oppisite of what i need it to do. Does anyone know how to make it do what i need to do here??
 
By chance are you running one of those reverse geared live toolholders? ...if so, just change the program to read M203. (I have to do this on some of ours)
