This phase of work is about training the machine to know its X,Y,Z limits. I reckon it could be done in about an hour by an expert so I'm putting three evenings down to our training needs as well. We had to calibrate several times due to human error.
The test print (the white objects) is a set of tools needed for final calibration tests, but I dare say there will be more tweaks to do in the future. Print time was about 2 hours.
The photo shows a vertical column on one of the pieces being made.
