Declaring variables in config.g

Nightowl

@owend So the original line should be changed to this:

if {state.currentTool >= 0} & {tools[state.currentTool].spindleRpm >= 0}
      set {global.savedSpindleSpeed} = {tools[state.currentTool].SpindleRpm}
...

... or should the lower line be enclosed within a single pair of curly parentheses?

As an aside, is "SpindleRPM" the same as "spindlerpm" and SPINDLERPM?

Thanks

No, you only need the curly brackets when doing a comparison using OR or AND
This groups and separates the parts of the equations
You don't need them when setting the value of the variable.

if {global.A = global.B} & {global.B<global.C}
   set global.D = global.B

if {global.A = global.B} || {global.B<global.C}
   set global.D = global.B

You also need them when you must calculate something as part of a standard command such as using a variable in a speed setting

G1 X100 Y100 F{global.D}

No they are not the same.
The object model values and variable names are case sensitive.

@owend Well, I'm definitely missing something, because the resume.g file doesn't restart the spindle, when I expect it should.

This is the declared variable in config.g:

global savedSpindleSpeed = 0

This is my pause.g file:

G1 Z{max(move.axes[2].userPosition+5,move.axes[2].max-5)}			; move the Z axis to a safe height
if {state.currentTool >= 0} & {tools[state.currentTool].spindleRpm >= 0}
	set global.savedSpindleSpeed = tools[state.currentTool].spindleRpm	; save current spindle speed
G1 X273.5 Y560 F2400								; move XY to a safe place
M5										; turn the spindle off
echo "Spindle speed saved at", global.savedSpindleSpeed, "RPM"			; spindle speed saved

...and this my resume.g:

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"
G1 R1 X0 Y0 F2400			; go above the paused XY position

This should be easy with all the help I've had, but what have I missed..?

Can you try this to ensure that the condition is being met.

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"
       G1 R1 X0 Y0 F2400	
else
       echo "condition not met.  Spindle speed remains at " ^ tools[state.currentTool].spindleRpm ^  "RPM"

I can, @owend, but running pause.g indicates the spindle speed of 0RPM is saved, not the 18,000RPM it's running at, so it seems to be an issue with pause.g?

This will be the problem.
See the other thread.

@owend

This is Line 14 from resume.g...

   echo "condition not met.  Spindle speed remains at " ^ tools[state.currentTool].spindleRpm ^ "RPM"

with the same error when I changed it to:

   echo "condition not met.  Spindle speed remains at ", tools[state.currentTool].spindleRpm, "RPM"

See the other thread.
I suspect you have no tool defined when the resume starts.
