If you are milling the holes to size you need to use one type of program if you are boring with a boring bar then another is needed :-

To mill the holes.

(USING 10mm CUTTER)

G21 G40 G00 G49 G54
M6 T1
S7000 M3
G90X107.5 Y-35.
G43 H1 Z6.
M98 P1001
X107.5 Y35.
M98 P1001
X-107.5 Y35.
M98 P1001
(Etc......)
M30

O1001
G90Z1.
G91G01 Z-5. F50.
X4.25 F100.
G03 I-4.25 F125.
G01X-4.25
G00 G90 Z1.
M99

(USING A 18.5 DIA BORING BAR)

G21 G40 G00 G99 G54
M6 T1
S7000 M3
G90G43H1Z6.
X107.5Y-35.
G81 G98 Z-5. R1. F25.

Mach3 is a different system, will your original code work on a Haas, Fanuc, Anilam, Meldas, Heidenhein, Sinumerik no it will not so why should it run an Mach3 and why is your old control doing it the right way and every other doing it wrong, simple answer is they are not, they are all g-code controls and all produce a part.  They just use a different dialect with custom functions.

General Mach Discussion / Re: Lathe Tool Compensation Is there a better way??

The other option is to make tool holders that hold the tools at 30 degrees and keep the tool post at zero.

The original idea was to have moderators from all time zones so we had 24 hour coverage.  As we have just about stopped the spammers that used to drive us all mad with there constant bombardment we probably don't need as many, but what the hell it costs nothing to have plenty.

No, Mach3 has to have a file loaded into memory, Mach3 has no limit on file size.

G31 z-10 f25. will move the z axis minus 10mm unless it senses the probe touch something. At the touch point it stops and you can take a reading and do what ever you want with the data by calling a M code.
