I have a calibration object, 20mm x 20mm x 4mm. Top layer in the gcode is at 3.90 - this shows as well if I use octo's gcode viewer. The file list (and the stats in the gcode viewer) shows size (including skirt) as "Model size: 27.63mm × 27.63mm × 3.52mm".
What I'm wondering is why the size is so far off of what's in the gcode? it also happens to be printing at almost exactly this size - but i'm in the recalibration process after upgrading from 18tooth to 20tooth drive pulleys... it's just weird that it's printing the same "off" size that OctoPrint says the print is.
