Thanks for sharing. Everyone has slightly different techniques. For example, I use my tacking iron completely differently. You seem to use the tip to 'draw' lines, where I just put it down flat and slightly move it back and forth on one spot. This seems to be more gentle with the print.
One contribution I like to make refers to the print position on the mount board (see attached). It's called: finding the optical center. I don't use it as a rigid rule, but as a starting point from where to improve the print position further. I also look for even borders (top and sides) as long as the bottom border is always slightly wider than the top.
