Control LED lights with conditional code

Thanks - I've combined that and another piece of conditonal g-code into the deomon.g file in this way:

if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed || !move.axes[3].homed ; if axes are 0,1,2 and 3 are not homed do...
M42 P4 S0 ; Turn LED off (Warm White)
M42 P5 S0 ; Turn LED off (Blue)
M42 P6 S0 ; Turn LED off (Red)
M42 P7 S0.1 ; Turn LED on (Yellow)

elif state.status == "paused"
M42 P4 S0 ; Turn LED off (WW)
M42 P5 S0 ; Turn LED off (Blue)
M42 P6 S0 ; Turn LED off (Red)
M42 P7 S0.1 ; Turn LED on (Yellow)

elif state.status == "processing"
M42 P4 S0 ; Turn LED off (WW)
M42 P5 S0 ; Turn LED off (Blue)
M42 P6 S0.1 ; Turn LED on (Red)
M42 P7 S0 ; Turn LED off (Yellow)

else
M42 P4 S0.1 ; Turn LED on (WW)
M42 P5 S0 ; Turn LED off (Blue)
M42 P6 S0 ; Turn LED off (Red)
M42 P7 S0 ; Turn LED off (Yellow)

I'm finding state.status == "resuming" doesn't work - I'm not sure if it is happening too quickly so I'm about to try put a dwell command in the resume.g file. Otherwise the lights remains yellow from the pause while the machine has already resumed the cutting procedure.

I've also had another idea - therefore a question about oscillating the PWM signal from the fan headers to differentiate between a solid yellow for axis being un-homed and a diming to bright looping yellow for paused. Do you have any advice on where I can find information to help me do that? Thanks again.

Just to add to the above - it seems that the resuming state happens after the resume.g file occurs - which is why I can't refer to state.status == "resume" in the resume.g file.

As it stands it can take up to 10 seconds before the red warming lights turns on after resuming form a pause with the above code in the daemon.g file by which time the machine has already started cutting. The pause.g and pause state occur more simultaneously.

Where this could become a bigger problem is if I were to write additional M42 commands in the daemon.g file to trigger relay modules to operate a dust extractor and air filter for a CNC router machine - up to 10 seconds is too long to wait for the extraction to turn on - especially if a cnc machine is already cutting and producing dust.

you could "cheat" the system I suppose and use a work place co-ordinate as a trigger that resume has been called.
I.e. something like

G10 L9 X1

Then check if its set to one in the daemon file.

if move.axes[0].workplaceOffsets[8]==1
   do x
   G10 L9 X0

So running the code and then setting it back to 0.

This will be easier once variables come in

@jay_s_uk just had a thought that I could call the daemon.g file using the m98 command in resume.g - but I'll have to wait to test that next time I can get in.

@EducatingSavvas daemon.g is ran roughly every second on its own thread i believe so theres no need to call it

I will investigate whether or not the Resuming state is being reported correctly.

dc42

I confirm that the Resuming state is not reported correctly. I will try to get this fixed in time for 3.2beta3.

@dc42 The resume state is behaving properly now. I though there was a problem with the pause but had change my conditional code to the following to include the pausing state. Really happy with how this works now.

if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed || !move.axes[3].homed ; if axes are 0,1,2 and 3 are not homed do...
M42 P4 S0 ; Turn LED off (Warm White)
M42 P5 S0 ; Turn LED off (Blue)
M42 P6 S0 ; Turn LED off (Red)
M42 P7 S0.1 ; Turn LED on (Yellow)

elif state.status == "paused" | state.status == "pausing"
M42 P4 S0 ; Turn LED off (WW)
M42 P5 S0 ; Turn LED off (Blue)
M42 P6 S0 ; Turn LED off (Red)
M42 P7 S0.1 ; Turn LED on (Yellow)

elif state.status == "resuming" | state.status == "processing" | state.status == "halted"
M42 P4 S0 ; Turn LED off (WW)
M42 P5 S0 ; Turn LED on (Blue)
M42 P6 S0.1 ; Turn LED off (Red)
M42 P7 S0 ; Turn LED off (Yellow)

else
M42 P4 S0.1 ; Turn LED on (WW)
M42 P5 S0 ; Turn LED off (Blue)
M42 P6 S0 ; Turn LED off (Red)
M42 P7 S0 ; Turn LED off (Yellow)

Thanks for confirming.
