ShopMaster MILL TURN, Setup Manual

Page: 23 / 23

EDIT- click on that and the G Code file will show in a window. You want to put a
pause in the program so that you can adjust your rpm.
You will see a line that reads M0 3 S??? (The S number will be the rpm you set in
the wizard )
Hit enter and on the blank line type in M1. M1 is a code to stop the program.
Close the edit window and say “yes” to save the changes. Now you are ready to run
the threading program- on the lower left selections you will see “CYCLE START”
click on it and the program will begin. You will see a couple of quick Z, X moves,
then nothing because you have come to the M1 command which has stopped the
program. Now it’s time to set your spindle rpm.
Go to your VFD key pad and press RUN and then turn the speed control knob to
start the spindle. Watching your S TRUE line on the Mach 3 screen and adjust the
control knob until the rpm matches the speed you selected on the S line. It won’t be
possible to get the match absolutely perfect, but within 5 rpm is fine. Now you can
go back to the Mach 3 screen, hit cycle start again and the program will run its full
course. By setting the spindle speed manually, what you have accomplished is to
eliminate one of the functions of Mach 3 and freed it up to “concentrate” on
adjusting the feed rate to match the rpm.
