UPS 24v on SKR PRO RRF 3
Hello all i wonder if i can get some help here , i have the following :
SKR PRO ver 1.2
Smart Effector ver 2
Board: STM32F4 SBC (STMSBC)
DSF Version: 3.2.0-beta1+1
Firmware: RepRapFirmware for STM32F4 based Boards 3.2-beta1_2 (2020-09-15b1)
Am trying to add Resume by using the Bigtree UPS 24v , which have 2 wires to the PS 24v and another plug for a 3 pin connector , anyone can help how to configure it in the RRF config files and where to connect it to which connector on the SKR PRO
thanks in advance

AFAIk RRF3 doesn't yet have support for a power loss input, but you have to set it up as a trigger on a available pin and have the trigger macro in turn execute your pause.g (or replicate its function in the trigger macro)

@bearer so i put the 3 pin one one empty one ok then i put the M581 in the config.g as
M581 P"e0stop+e1stop" T2 C1
Trigger 2 is a pause
now my questions how to save the last position of the hotend and how to resume ? and how to make the 3 pin monitor the power ?

i thought pause handles the saving, according to https://duet3d.dozuki.com/Wiki/Gcode#Section_M916_Resume_print_after_power_failure
and how to make the 3 pin monitor the power ?
presumably one of the three pins go high or low when the power input fails, but i'm not familiar with the module
so i need also to use M911 in the config.g but let me ask you this if the pause saves the last position of the print i need to make a marco to get this info and resume how ??
@bearer here is the one am talking about https://www.biqu.equipment/collections/expansion-board/products/btt-ups-24v-v1-0-resume-printing-while-power-off-module
@bearer so if i do this M581 P"!e2stop" T2 C0 means when the inverted pin goes from 5 v to 0 do a pause is that right ?
but if the power is cut and these capacitor keep it alive for 1 more min and it paused how it will resume what do i need to do to get it to resume ?

@sankafola I'm interested too because I have a 12VDC power supply and to be able to use the resume after power outage I thought to buy this:
So it would be possible to connect the otuput port of this "UPS" to a free pin of the DUET 2 Wifi and trigger a pause?
