General Mach Discussion / Re: Work offset changes if i press reset

What is in the fixture offset table before and after this happens?

Why are you using so many fixture offsets?

Can you post your gcode.

You can set your Fixture position in to offset G59.253 and set the option in general config, this will then copy the figures into G54 on start up of mach3.

Are you saving your fixture offsets after you have set them from the offset tab.

If you are working from the table top.

1. Go to mach3 offsets screen, select G54 top centre of screen, making sure end of spindle or what ever you use for the datum is correct value from Z home to table top.

2. Bottom right of offset screen set tool number to 1 and 'Gauge Block Height' to zero or if you are using a feeler gauge set to thickness of gauge.

3. Move tool and touch on table top or feeler.  Press 'Set Tool Offset' button.

4. Change to tool 3, set tool number to 3, touch on table top or feeler, press 'Set Tool Offset' button.

That should be all you need to do.

That is a post issue in fusion, try using a different post, fanuc 6 mill may be better, there may also be an option on the post config screen to change the rapid move to xy then z

You need to change the H0 to H1 when using tool offset 1 and H3 when using tool and offset 3

your tool offsets need to be set too.

T1 M6
S5000 M3
G0 X-21.415 Y-1.669
G43 Z15. H0

Have you checked for a setting in the PMDX that might send the machine to a point after homing.

My guess would be you need to set the A axis rotation in Config - Control - Tool path

You also have no Y axis start point in the code.

I seem to remember you have to set the plane to XY (G17) just before the canned cycle and put it back to XZ (G18) after the G80


G00 G90 X0 Z5. G97 S500 M3
G81 Z-4. R1. F.15
G00 X50. Z100.

G91 G28 A0 will home the A axis.

You can change the motor direction in the servo drive parameters.
