Strong work, Luke! That does indeed look nice.
:)
i think that's it (oh, except the step needs adjusting to 15mil not 5mil as it is now). now i have to identify where in the PADS file the rectangle for the keepout area is, add *that* to the parser as well, then do the same maths and create a tethered keepout area. *sigh*...
I'm sorry I didn't fill in more of the geometric considerations. Looks like you have them in hand.
in drunken-walk programming style .... yyyeah :)
When the step offset is d, then the 45 degree step travel will be sqrt(2.0) * d.
Looks like you have the starting positions parallel which was the intent but I did not specify the mathematics. I didn't know what origin or reference point and direction you would like to use.
i had the picture you drew memorised in my mind and realised the mistake.
so... ah.... key question here... is the taper needed or not? :) should i instead be just setting 15mil clearance all round? (and put a GND keepout underneath the ESD)?
