Resume print after comms failure
Having the ability to resume a print after a communication failure. Perhaps create a log of all failed prints and their last acknowledged line of g-code. Then have the ability to resume the print at that location in gcode. It would probably need the ability to reheat the bed and nozzle before resuming. Perhaps also have the option to run a custom gcode script before resuming as well.
This would allow print resuming if the power fails and you have a UPS on your computer, a battery backed RPI, or after a simple comms glitch, etc...
The Raise3d N2/N2+ has a controller / touch ui that is similar to a battery backed RPI that does this if the power fails.

In next release we have a history. I will see if I can add something like position in the history notes and maybe add a @continueAt command to skip lines. But as I said it requires you to be able to rehome to continue.
Unless the printers firmware can retain (or send) from history what the last mesh bed leveling values were, it would not be able to restore/resume the print no matter how much history you have from the previous g-code.
Trust me, it would be awesome if we could get this, however most printers are a one way street in regards to data.
Next server release will put in history log at which line and layer the print stopped so you have the chance to prepare a print for continue if physical possible.
Most printers won't loose their physical Z position if power is lost and the server would know the last acknowledged z position. You could move the Z axis up say 5-10mm home the X and Y and reload the z position. If all else fails let the user manually set the level of the Z axis and like you would on a CNC machine. Again if you have the feature firmware support will come.
