M911 won’t work
-
I’ve set the M911 option on my duet but, also manually decrease volt from 24 to 12 volt with a decrement also step of 0.1V duet won’t stop.
There are need some specific file in order to activate this features?
I’ve set M911 to pause print at 22 volt and resume at 30 volt ( no auto resume ).
Please help me!!

Please tell us the M911 command you are using, and the version of firmware on your Duet.

Firmware 1.21
M911 S25.0 R50.0 P"M913 X1000 Y1000 G91 M83 G1 Z3 E-5 F1000 G90 G1 X0 Y0"I’ve found that if I set the parameter R to a normal voltage like 24 volt then the auto pause is working properly... maybe a bug?

I have just checked the code. Currently it requires the initial voltage to be at least the resume voltage in order to prime the auto save system. This is to prevent the firmware thinking that there has been a power failure during startup.

@dc42 understand. Then no auto resume option?
https://duet3d.dozuki.com/Wiki/Gcode#Section_M911_Configure_auto_save_on_loss_of_power
Raaa Resume threshold in volts. Must be greater than the auto save voltage. Set to a high value to disable auto resume.
-
What might work is to set a low auto resume setting initially, then use a G4 delay command to allow the system to prime itself, then increase the auto resume voltage.
I guess I could allow the system to prime itself when the voltage exceeds the power loss threshold by 0.5V or something like that.
