JMahon thank you for sharing your knowledge, helped us big time today

if you guys are running haas machine use g47 for the engraving. the machine will generate the code for you once you have the proper values into the program. here is the hand written program we use, for all our engraving on the haas we just change the values according to the size of the part. IF THE PROGRAM IS CORRECT THE MACHINE WILL GENERATE THE CODE FOR EACH NUMBER, LETTER AND CHARACTER THAT YOU HAVE GIVEN IT IN THE BRACKETS. (THIS PROGRAM WAS WRITTEN USING THE CENTER OF THE CHECK AS Z0.0) THIS PROGRAM IS FOR ENGRAVING ON A 4TH AXIS, THE Q=D OF SURFACE YOU ARE ENGRAVING, I = DIRECTION OF LETTERING, J = SIZE OF LETTERING (HEIGHT AND WIDTH WILL BE AFFECTED.) TO CHANGE SERIAL # ALL YOU HAVE TO DO IS CHANGE THE LAST NUMBER. ONLY HAAS MACHINES CAN USE THE G47. WE DO ALL OUR ENGRAVING THIS WAY VERY EASY TO CHANGE ANYTHING WE NEED TO ENGRAVE ON THE PART, NO NEED TO WRITE LONG COMPLEX PROGRAMS) T22 M06 (engraving tool) G00 G90 G54 X8.0 Y0.0 A-155.0 S6000 M03 G107 A0.0 Y0.0 Q4.36 G43 H22 Z3.0 M08 Z2.75 G47 P0 Y0 I90.0 Z2.168 J0.25 R2.225 F10.0 E5.0 (PN-50-16-605 REV B.0 PO#2354 W0#99028-01 PTS 72907) G00 Z5.0 M09 G107 M05 G91 G28 Z0.0 Y0.0 M00 (CHECK CIRCUMFERENCE OF PART) G00 G90 A-155.0 M00 G90 A0.0 M30
