some questions about configuration

droftarts

@cosmowave For (1), you're using the RepRapFirmware 2 notation for MCU temperature. See https://duet3d.dozuki.com/Wiki/Mounting_and_cooling_the_board#Section_Notes

For (2), I'm not sure why it triggers on rising and falling edge, when you've set S0. @dc42 ?

for (3), it's because the status changes to 'busy' when you run a macro, even if the printer is idle (at least it does when I just tried it out). I think the following document lists the main runtime states as idle, busy, printing, paused, halted, resuming and changingTool (though may be slightly out of date): https://duet3d.dozuki.com/Wiki/Status_Responses
Again, @dc42 may be able to elaborate on all the different states and exact wording reported for each state.

@droftarts thanks for your explanation.

For (1), you're right! I will try it like this and check it today evening:

M308 S3 P"mcu-temp" Y"mcu-temp" A"MCU"    ; configure sensor 3 as mcu-temp on pin mcu-temp, show temp in graph as MCU
M950 F1 C"fan1" Q500                      ; create fan 1 on pin fan1 and set its frequency (MCU fan)
M106 P1 T25:60 L0.4 X1.0 H3               ; set fan 1 value. Thermostatic control is turned on (MCUtemp start @25°with40%, full @60°)

for (3)
i think, my coding (with status.state) is not the best for option for switching between "no print is running" and "a print is running"!
Do you know which variable i can take to make a switch if a print is running or not?

@cosmowave said in some questions about configuration:

The trigger is working, but on falling and rising edge of the signal. This is not a big problem, but i d'like to know why! With this code, it should only trigger at falling edge!?

Contact bounce, perhaps? I can look at adding a debounce option to M950 with J parameter.

cosmowave

@dc42 hmmm, that can be. Its an old relais switching this input.
I try to measure it with my scope...

Do you have an idea about my other problem described above?

@cosmowave, I think there are several values in 'job' that you could test, such as job.duration and job.fileName.

cosmowave

@dc42 i can't see job.duration in the object model! Does it exist?
i think, job.layer can be a good candidate?

droftarts

@cosmowave Or you could flip the macro around so that it checks if it's not printing:

if state.status!="printing"
  M98 P"0:/macros/NoFlowNotIdle"
else
  M98 P"0:/macros/NoFlowIdle"

@droftarts yes, that's an option.
But i'm not sure, if the state is changing to something other than "printing" during a print!?

I can see job.duration in the OM browser, it's null because no print is running. I am running firmware 3.3beta3.

job.layer is not reliable in firmware 3.3 because we've given up trying to second-guess which layer is printing, unless there are layer comments in the GCode file.

Is it possible to add a debounce option?
