Recovering a stopped print after a fault
-
I have a long print mid way through and experienced a heater fault that stopped the print. M562 cleared the fault ok DWC did not keep the print active as it was sleeping. is it possible to find the print stop position and recommence (continue) the print?
-
@iains I have found the Resurrect.g file relative to this print. I homed the printer and ran M916. When I run M916 i get this:
Error: M916: Resume prologue file 'resurrect-prologue.g' not found.
Yet the prologue file is present in the resurrect file? as below. What steps am I missing to resume the print?; File "0:/gcodes/CFFFP_Mask 13 Pattern correct for 3D PRINT (2) Full Size PLA.gcode" resume print after print paused at 2020-08-19 05:02
; File "0:/gcodes/CFFFP_Mask 13 Pattern correct for 3D PRINT (2) Full Size PLA.gcode" resume print after print paused at 2020-08-19 05:02

Do you have a file called resurrect-prologue.g in the /sys folder? You'd want to set it up so that you can home the printer without hitting the print on the bed.

No i dont have it set up. Does a manual home sequence not have the same effect

Well if you want to use M916 to resume the print it expects there to be a prologue file to prepare the machine for resuming the job. You can probably safely home X and Y with G28 XY?
Then for z you can either add a manual probing at a specific safe XY coordinate and probe type 0 (M558 P0) to give yourself a jog dialogue to manually touch the nozzle to the bed to home Z. Or you can position it at a known height and use G92 to set it.
It's really up to you how you do it. The file could be largely blank if you want as long as you know you've got XYZ homed to match what's on the build plate.
