If you enter G01 G91 Z-10. F50. the machine will move in incremental steps of 10mm.

General Mach Discussion / Re: Mach4 Stops at G98 G81 - No error

Line 118 has 2 G00 commands (G00 & G0)

Try putting the G98 on the line before the G81

Are you going to hit the Z- softlimit ?

It Could be a setting in the 'General config'

G50 S2000 before the G96 line will set the maximum spindle speed to 2000 RPM in G96 mode E.g.

G50 S1500 (max rpm set to 1500)
G00 X100. Z1. G96 S200 M3
G01 X-1. F.25
G00 X100.

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.

General Mach Discussion / Re: MACH 3 M6 modifies Z in the G54

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.

(2D CONTOUR2)

T1 M6
S5000 M3
G54
G0 X-21.415 Y-1.669
G43 Z15. H0

Mach4 General Discussion / Re: How do I disable fixture offset (after reference all axes)?

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