"The latest hardware versions of the EBB (1.5 and 2.0) with the latest firmware (2.0.1) have the ability to monitor the power input from the wall. Because the boards are also powered from USB, you can't easily tell (from the LEDs, for example) if you've got good wall power on your EggBot.
This is a request to add a feature to the Inkscape extension that would query the EBB for the current voltage level at the power input jack, and warn the user if they try to run their EB without power (or with power less than, say 8V).
The EBB command to use is the QC command."
From Ragstian:
"Code to manually read the voltage and current setting has been added to the eggbot extension, (eggbot.py and eggbot.inx). See this forum thread for the updated files.

From Brian:
"The code that ragstian added works to properly detect the input voltage to the EBB. Note, however, that you need to use v2.2.3 of the EBB firmware in order for this to work correctly. Previous versions had a semi-broken QC command.
At this point, I think all it would take is a little python to send the QC command and verify a minimum voltage (say 8.5V) before the beginning of a plot."
