Hi, wonder if anyone still interest about this topic --- the Power loss function is not fake and actually included with the firmware, just waiting to be activated for some older machines.

I wonder why no-one from Geeetech response to you so far, so I post the simple solution as my A20T also do not have the resume function when I got it, but can be reactivate using Gcode input to the firmware.

I test the method with my A20T and get satisfactory results - using Gcode command only.

Method -......

Connect your printer to "Repetier Host" baud rate should be 25000 and make sure the Repetier Host can manual control the printer.
use the Gcode input box to send Gcode as below

M413 S1
M500

Hit send ....... and you are done.

you can try next print using pause print function and it should be asking for resume print for you to continue print....

Same when you turn the power button off and re-start or power come back after power lost.
But do not leave the printer un-attended after power loss, turn off the power button and switch power button on after power resume to continue print.

I am just another user try to share what I find out about this topic. :geek:
