Can I define an own under voltage value?

Hi!

I am running a Duet3D 1.03 at 24V but sometimes it happens at power-up, that my PSU provides 12V only. I know, that there is someting wrong with the PSU. But it is possible the set a custom under voltage value? For example at <21V.

@ikarisan in terms of undervoltage for pausing the print.. M911 allows you to set voltage below a set threshold that will initiate the power fail actons:
https://duet3d.dozuki.com/Wiki/Gcode#Section_M911_Configure_auto_save_on_loss_of_power

So you could potentially re-purpose this to check the power level at the start of a print, using M117 to send you message if the power was below your set threshold ( i have not tried this).

@T3P3Tony This is an interesting approach. I'm gonna check this out...
