There might be a safety issue here, in that keeping the spindle running until it moves to the safe place might prevent the bit from snapping (or worse, damaging the milling motor) if it were to hit the stock.

This is my pause.g file (it includes triggering a LED to show it's in Pause mode and a method of storing the spindle speed on resume*):

; pause.g M42 P8 S0 ; pause/resume LED off set global.PausePress = !global.PausePress ; toggle the value from whatever it was before set global.savedSpindleSpeed = spindles[0].active ; sets the global variable echo "Spindle speed saved at ", {global.savedSpindleSpeed}, "RPM" ; shows saved spindle speed in the Console G1 Z{max(move.axes[2].userPosition+5,move.axes[2].max-5)} F2400 ; move the Z axis to a safe height G0 X273.5 Y560 ; move XY to a safe place M5 ; turn the spindle off

...and the respective resume.g (with a bit of tool confirmation, but some of this might be spurious - but it works!) but note the indents are critical:

; resume.g M42 P8 S1 ; pause/resume LED off set global.PausePress = !global.PausePress ; toggle the value from whatever it was before if state.currentTool =-1 echo "No tool active. Selecting tool zero" T0 ; select tool zero if state.currentTool >= 0 echo "Spindle state on tool ", state.currentTool, " is ", spindles[state.currentTool].state if {state.currentTool >= 0} & {tools[state.currentTool].spindleRpm >= 0} M3 S{global.savedSpindleSpeed} ; resume saved spindle speed G4 S1 ; wait 1 second to allow the spindle to spin up echo "Spindle speed resumed at " ^ {global.savedSpindleSpeed} ^ "RPM" ; this should show that the setting was successful G0 R1 X0 Y0 ; move X and Y back to saved work XY location G1 R1 Z0 F240 ; move Z slowly down to saved work Z location

*I'm happy to provide the configuration lines from the config.g, stop.g and trigger2.g files, if you want to incorporate those features, too?

Sorted it and dancing around the workshop .
Looked at all the frequency settings on VFD and noticed that PD011 was set to 200.00. Set it to factory 0 and it all works.
Thanks so much for all your help. This forum is invaluable.

@peteupshall I do XYZ probing on my milling machine.

A - I have a physical endstop for each axis (XYZ) that lets me set a physical origin. These, with config.g settings, are used to set up the physical bounds for the machine.

B - when milling I use the XYZ probing to set the stock origin.

I've considered using XYZ probing to set the physical origin and boundaries but really there's no easy way to do that initial probe automatically without endstops so never bothered setting it up.

There's a writeup in my personal wiki (with script for the probe and results of physical tests) here: http://eadia.com/pmwiki.php?n=Taig.Probing

My Globals settings for the probe->

; global <new-variable-name> = <expression> ; touchpad center and height global TouchX = 15 global TouchY = 84 global TouchZ = 13.125 ; the touchpad Z offset from ground ; speeds for probing global ProbeFastZ = 400 global ProbeFastXY = 300 global ProbeSlowZ = 200 global ProbeSlowXY = 50

Here's my Z probe code (I use the bed location usually, so) ->

G53 G0 X{global.TouchX} Y{global.TouchY} G30 S-1 ; lower z until the metal probe is hit G10 L20 P2 Z{global.TouchZ} ; Z = 0 + puck height in second coord system G1 Z38 F600 ; raise z one inch

Here's my X probe current code (with a 1/4" bit)

And the submacro:
