Fatal error when parsing G92 commands - 'NoneType' in AxisPosition.py #60

Open AndrewFRC135 opened 3 years ago

I am using this plugin in conjunction with the GPX plugin to run my Makerbot Replicator 2. I suspect maybe there is a conflict between the two, since the GPX plugin manages the gcode offset commands. Below is a snippet of my log file showing the error.

ExcludeRegion seems to fail whenever a G92 command is issued, as one of the variables appears to be a 'NoneType'. This failure causes the GPX plugin to ignore the G92 commands, leading to incorrect printer behavior. Below are my relevant version numbers. I am using Simplify3D as my slicer, if that matters.

Octoprint Version: 1.5.3 Exclude Region Version: 0.3.0 GPX Plugin Version: 2.6.8

Same thing. Python 3.9, OctoPrint 1.9.2 Latest version of the plugin.
