Power Loss

Hello,

in case of Power Loss, is it possible to save the state of the print and start over from that point?
I did not find any topic on this.

I do not print from SD and Marlin or other solutions are always from a print initiated from the sd card.
I use software to manage the printer so I would like to have the option to save the state of the print and in case of power loss, to recover the print from the point it stopped.

Possible?
Thx

  • In combination Repetier-Firmware 1.0.4dev and Repetier-Server that is possible. Repetier-Server is our only product supporting recover.

    If you use any other firmware recover will still work but it will not know exactly where you stopped, so you need to select the starting point manually. Works quite good if the pc running server does not also loose power or if it was just a usb disconnect. Works better if firmware can send a message to detect power loss early.

    You can still print over host using repetier-server connector, only for recovering you need to switch to server gui.

    ok. I use repetier host and have Marlin firmware on the custom printer.
    Isn't possible to recover from repetier-host by saving the state/layer at which is printing? like resume print?
    Got cases where power was lost or print stopped, and just want to restart the print from where it was stopped.
    I am going to print for a couple of days so having this would be great.
    Maybe is a feature request?
    thx
  • As said repetier-server can do that. It logs positions send and can continue. Problem is just when you loose power the end of log will be missing and firmware will not tell where it stopped. So it is then up to you to find the correct position. Server will show until where it logged and the gcode in question and you just say from where to start.

    You also need a way to find correct xyz position. For xy you can say to home xy which normally works. For Z you can do z max homing or assume you start at last Z so you define Z with G92 (ok server does that). And hope firmware does not require homing z in that case. If firmware requires home z to move and you have z min homing you are lost anyway.
