printhistory failing with AttributeError: 'NoneType' object has no attribute 'parse' #48

Closed pdvorak57 closed 7 years ago

pdvorak57 commented 7 years ago

I installed printhistory plugin on octoprint 1.3.1, and I don't have any print history information, and I am getting the following error in the logs:

what slicer did you use for that gcode file?

pdvorak57 commented 7 years ago

cura 2.3.1 on Mac. It fails for all the prints I am doing, do you need to see the gcode?

imrahil commented 7 years ago

do you need to see the gcode?

yes, please

WDI_elf_ranger_supports.gcode.gz

I have the same problem:

BTW - I have this problem when using Cura 15.02.1, when I use Simplyfi3d, it's ok.

danielei commented 7 years ago

but before I installed Octoprint 1.3.1 it used to work on Cura as well.

Parser searches for Cura_SteamEngine string on the first 3 lines. Increasing this constant to 10 should help. https://github.com/imrahil/OctoPrint-PrintHistory/blob/master/octoprint_printhistory/parser.py#L49 p.s. i will check
