To make the Mcode open the VB editor from the main screen.
Type in the command
DoOemButton(1014)
Save the Code as M### (pick your number here) Say M900
Save it to the macro directory.
How I normally use that particlur call is to use it with the block delete charector that way I can turn it on and off in the program. Most times when running a new or copmplex program I start the program at 1/2 of the normal feedrate. Then IF all is well I up the feedrate to normal.
Hope that helps, (;-) TP
