If you go to the Diagnostics, page just above the reset button you can turn off the toolpath.

It should help.

Put this on the last line of your code


This will make the machine home them stop

G28 X0 Y0 Z0 (go to axis home)
M30 (end)

Or

This will make the machine loop for ever or until you select optional stop

M1  (optional stop)
M47 (run from start)

Hi,

Machines work from a datum point, this can be set anywhere within its working envelope, you can then work in absolute movements or incremental moves.

Absolute (G90) commands work from the datum point to the commanded position.

Incremental (G91) commands work from the current point and move the commanded amount.

E.G. to move in a 2" square using absolute the code would look like this :-

G20 G40
G00 G90 X0 Y0
G01 X2. F10.
Y-2.
X0
Y0
M30

And the same in incremental :-

G20 G40
G00 G90 X0 Y0
G91
G01 X-2. F10.
Y-2.
X2.
Y2.
M30

I hope this helps.

Graham.

G03X3.2480Y1.0313I-0.1250J0.0000 Q0.1250

Mach dose not support the Q command in G03's

You need to amend the post processor to remove the Q's

I must agree with Hood, the only safe way is to stop the machine, you can not send it to home as you have no idea what the safe path to home is at any given point.

You could make the spindle switch latch a relay that cuts the power to the spindle and the axis drives.

Normally you would output without any options ticked, then you should get a single line of code for each move down in Z.

E.g. 

G03 I-.25 Z-.05
G03 I-.25 Z-.10
Etc.

What did you use to create the code and the drawing?

The code is very long for such a simple job.

What are you using to draw the DXF's ?

There is no threading in ether of your files.

If I am understanding what you intend to do then Mach3 is not designed to do that, it has no direct feed back from your machine.
