@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.

@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.

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 ?

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 ?

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

Yes i have double checked the orientation, accelero +x = machine +x ; accelero +z = machine -y

M593 P parameter is temporary i was playing around with it, but 66hz is what i get all the time

Hello everyone,

I have installed and wired an LIS3DH accelerometer from Adafruit, got it to work and am able to capture data both with M956 or via the Input Shaping plugin.
However when applying any of the shapers and recapturing a motion profile, i do see a reduction in ringing for the X and Z values , but Y doesn't change or even gets worse.

Y axis is driven by two steppers on two seperate drivers could it be the reason ?

Thank you in advance

@dc42 That's good to know thank you !

Hi everyone, I would like the resuming of a print after an accidental switch off or blackout to be automated. It needs to work of the power has been shut or the print paused multiple times in a row. I guess I can call M916 in config.g if resurrect.g exists. But in order for it to not trigger when i start a new print, it means i should delete or rename resurrect.g at the end of the print ? Or rename it right after it has been executed ? Both ?
Also I'm not very good at electronics and would appreciate if someone could explain to me how to wire the capacitor as per this statement "Adding a 10000uF capacitor across the VIN rail can help increase the amount of stored power " in https://docs.duet3d.com/en/User_manual/Tuning/Resume

I have tested my setup and the resurrect seems to work, it seems like i don't need to home z as my lead screw has a 2mm pitch, i'll need to tune the settings and maybe add a high endstop to z but i'm not to worried about this part.

Thank you in advance

It was actually pretty fast, and the driver is doing fine

@jay_s_uk OK I'll try that. Again thank you very much!
