Thanks! I think I have this right. It seems to be slower executing the M220 S100 in my trigger file. I think I have this set right. There might be a better way but it works!
M950 J0 C"duex.e2stop"
M581 T7 P0 S0
In my trigger7.g file I have
M220 S5 ; set speed 5%
G4 S5 ;delay 5 seconds
M220 S100 ; set speed 100%
