Hi.

Looking at those calibration patterns - Isn't that what is described in the instructions (referring to the "square" here)
Quote:
Q:When calibrating I see an open book shape rather than a square.

A: We have seen this happen with some computer / monitor power supplies, try using a cell phone charger (500ma or greater) or plugging in to a different power source.

Maybe some issues can be resolved here with an external/different power-supply.?

Looking forward to seeing more prints. Keep up the good work

Kind regards
Martin - Really depressed that I only heard of this Kickstarter last week. Looking forward to web-shop opening to the rest of us.
