« on: July 25, 2013, 04:00:33 PM »

all you need to do is this :-

Rapid to the center + the circle radius + or - the radius of the cutter e.g.

G20 G40
(1/2" dia cutter and 3" hole centered around X0 Y0)
G00 G90 X1.25 (1.5-.25) Y0 Z1.
Z.05
G01 Z-1. F10.
G02 I-1.25
G00 Z1.
(Then a 1/2" cutter and a 4" boss centered around X0 Y0)
G00 X2.25 (2.0+.25) Y0 Z1.
Z.05
G01 Z-1. F10.
G02 I-2.25
G00 Z1.
M30

I sounds as if the tool definition in BOBCAM has a max length of 2"

Try it like this :-

N0040 G53 G90 G91.1 G40
N0090 M06 T2 F2000.0  (2000mm/min)

N0110 X89.4288 Y86.4878
N0120 Z0.0000
N0130 G28.1 Z0 (Z-Achse auf Home fahren)
N0140 G00 Z0 (Z-Achse von Offset auf 0)
N0150 M03
N0160 G03 J9.7500
N1000 M05 M30

All I will say is, don't expect future versions of Mach to work that way.

I am not sure what it is you are trying to do, G28 on its own will do nothing useful it needs an axis commanded with it, e.g. G28 X0 or G28 Z0 to tell it which axis to home not only that but you would normally have the machine in G91 mode to stop it rapiding via the datum point first.

A normal G28 command would look something like this :-

G91 G28 X0 Y0 Z0

This will send all 3 axis to the home position in one direct move.

G90 G28 X0 Y0 Z0

Will move to the home position by going to the current XYZ zero point first then to the machines home position.

You can also use G91.1 with G28 to search for the home position.

Something along this line will do the job
