Questions regarding various job time

[modl]

Hi everyone
I have a few questions I couldn't find an answer for in the different documentations and changelogs.

1. Does job.pauseDuration account for time that passed while the machine was off after a pause. e.g. if i pause my print, wait for 1mn , shut down the printer for 1 minute, then switch the printer back on and resume the print, will job.pauseDuration report 60 or 120 ?

2. Is there a way to store the start date and time of a print using a macro, as a global variable, at the beginning of a print for later access and operations in other macros ?

3. Does job.timesLeft.file use simulation mode? Will it take into account pause times determined by a macro ?

Thank you in advance

Best

1. I think pauseDuration only counts the time the machine is in paused state (pausing/paused/resuming). Making it also count the off time is quite hard because the time is probably unset when the machine comes back online, although I suppose you could save the current datetime when the machine encounters a power loss event. Then you could work it out yourself.

2. You can calculate that AFAIK because you can substract a number of seconds from state.time.

3. I think job.timesLeft.file just computes the ETA just by checking how quickly the current print file is being processed. No macro times are taken into account there.

If you shut down the printer and later resume the print, the calculated print finish time based on filament extruded will be wrong, because the amount already extruded isn't saved anywhere. Also job.pauseDuration won't account for any pauses done before the job was restarted, because the pause time (and heating time) are not saved..

You could set a global variable to the current start date/time in start.g.

No, it works on the proportion of the file that has been printed and the current rate at which the file is being consumed.

Thank you both for your answers I'll work with this in mind for now.

@dc42 if i set a start date time in the start macro , will it be persistent after machine is powered off, or there is a powerfailure ?

[modl]

i think I have my answer after some testing: no, global variables are not persistent when there is a power failure or emergency cut off. Anyway this can be done ? Like written to a single file using echo and read later ? Can i read strings from another file inside a macro ?

Yes, you can echo a command to a file to set a global variable.

@dc42 Thank you very much it works, I had to reread the Documentation to remember to use two double quotes to add a double quote to a string, to set globals in a datetime format.

@modl I'm glad you got it working. I'll mark this as solved, but you can revert it if you need to.
