Ah, this may be a Python2 issue...hard to believe you are the first to use the plugin with Python 2, however. I'll take a look!

Edit: it also appears you are having unrelated issues with eeprom_marlin plugin.

[The-EG]

Please install the latest version of the plugin, 0.3.2. This should now be fixed.

[BigDi]

Thanks. Plugin starts now. BTW: It shows values but the bed level visualizer plugin shows completely different values. It also shows correct values (NA) in the corners for my delta printer.

[The-EG]

I don't have a delta printer so feedback there would be good. I can't really speak to BLV, since that's a different plugin with different goals (BLV is more for seeing the overall orientation of the bed, this plugin is intended for manually editing the individual values).
